-The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.

+ Chapter 14: The inline disease
+
+There appears to be a common misperception that gcc has a magic "make me
+faster" speedup option called "inline". While the use of inlines can be
+appropriate (for example as a means of replacing macros, see Chapter 11), it
+very often is not. Abundant use of the inline keyword leads to a much bigger
+kernel, which in turn slows the system as a whole down, due to a bigger
+icache footprint for the CPU and simply because there is less memory
+available for the pagecache. Just think about it; a pagecache miss causes a
+disk seek, which easily takes 5 miliseconds. There are a LOT of cpu cycles
+that can go into these 5 miliseconds.
+
+A reasonable rule of thumb is to not put inline at functions that have more
+than 3 lines of code in them. An exception to this rule are the cases where
+a parameter is known to be a compiletime constant, and as a result of this
+constantness you *know* the compiler will be able to optimize most of your
+function away at compile time. For a good example of this later case, see
+the kmalloc() inline function.
+
+Often people argue that adding inline to functions that are static and used
+only once is always a win since there is no space tradeoff. While this is
+technically correct, gcc is capable of inlining these automatically without
+help, and the maintenance issue of removing the inline when a second user
+appears outweighs the potential value of the hint that tells gcc to do
+something it would have done anyway.

+I/O Barriers
+============
+Tejun Heo <htejun@gmail.com>, July 22 2005
+
+I/O barrier requests are used to guarantee ordering around the barrier
+requests. Unless you're crazy enough to use disk drives for
+implementing synchronization constructs (wow, sounds interesting...),
+the ordering is meaningful only for write requests for things like
+journal checkpoints. All requests queued before a barrier request
+must be finished (made it to the physical medium) before the barrier
+request is started, and all requests queued after the barrier request
+must be started only after the barrier request is finished (again,
+made it to the physical medium).
+
+In other words, I/O barrier requests have the following two properties.
+
+1. Request ordering
+
+Requests cannot pass the barrier request. Preceding requests are
+processed before the barrier and following requests after.
+
+Depending on what features a drive supports, this can be done in one
+of the following three ways.
+
+i. For devices which have queue depth greater than 1 (TCQ devices) and
+support ordered tags, block layer can just issue the barrier as an
+ordered request and the lower level driver, controller and drive
+itself are responsible for making sure that the ordering contraint is
+met. Most modern SCSI controllers/drives should support this.
+
+NOTE: SCSI ordered tag isn't currently used due to limitation in the
+ SCSI midlayer, see the following random notes section.
+
+ii. For devices which have queue depth greater than 1 but don't
+support ordered tags, block layer ensures that the requests preceding
+a barrier request finishes before issuing the barrier request. Also,
+it defers requests following the barrier until the barrier request is
+finished. Older SCSI controllers/drives and SATA drives fall in this
+category.
+
+iii. Devices which have queue depth of 1. This is a degenerate case
+of ii. Just keeping issue order suffices. Ancient SCSI
+controllers/drives and IDE drives are in this category.
+
+2. Forced flushing to physcial medium
+
+Again, if you're not gonna do synchronization with disk drives (dang,
+it sounds even more appealing now!), the reason you use I/O barriers
+is mainly to protect filesystem integrity when power failure or some
+other events abruptly stop the drive from operating and possibly make
+the drive lose data in its cache. So, I/O barriers need to guarantee
+that requests actually get written to non-volatile medium in order.
+
+There are four cases,
+
+i. No write-back cache. Keeping requests ordered is enough.
+
+ii. Write-back cache but no flush operation. There's no way to
+gurantee physical-medium commit order. This kind of devices can't to
+I/O barriers.
+
+iii. Write-back cache and flush operation but no FUA (forced unit
+access). We need two cache flushes - before and after the barrier
+request.
+
+iv. Write-back cache, flush operation and FUA. We still need one
+flush to make sure requests preceding a barrier are written to medium,
+but post-barrier flush can be avoided by using FUA write on the
+barrier itself.
+
+
+How to support barrier requests in drivers
+------------------------------------------
+
+All barrier handling is done inside block layer proper. All low level
+drivers have to are implementing its prepare_flush_fn and using one
+the following two functions to indicate what barrier type it supports
+and how to prepare flush requests. Note that the term 'ordered' is
+used to indicate the whole sequence of performing barrier requests
+including draining and flushing.
+
+typedef void (prepare_flush_fn)(request_queue_t *q, struct request *rq);
+
+int blk_queue_ordered(request_queue_t *q, unsigned ordered,
+ prepare_flush_fn *prepare_flush_fn,
+ unsigned gfp_mask);
+
+int blk_queue_ordered_locked(request_queue_t *q, unsigned ordered,
+ prepare_flush_fn *prepare_flush_fn,
+ unsigned gfp_mask);
+
+The only difference between the two functions is whether or not the
+caller is holding q->queue_lock on entry. The latter expects the
+caller is holding the lock.
+
+@q : the queue in question
+@ordered : the ordered mode the driver/device supports
+@prepare_flush_fn : this function should prepare @rq such that it
+ flushes cache to physical medium when executed
+@gfp_mask : gfp_mask used when allocating data structures
+ for ordered processing
+
+For example, SCSI disk driver's prepare_flush_fn looks like the
+following.
+
+static void sd_prepare_flush(request_queue_t *q, struct request *rq)
+{
+ memset(rq->cmd, 0, sizeof(rq->cmd));
+ rq->flags |= REQ_BLOCK_PC;
+ rq->timeout = SD_TIMEOUT;
+ rq->cmd[0] = SYNCHRONIZE_CACHE;
+}
+
+The following seven ordered modes are supported. The following table
+shows which mode should be used depending on what features a
+device/driver supports. In the leftmost column of table,
+QUEUE_ORDERED_ prefix is omitted from the mode names to save space.
+
+The table is followed by description of each mode. Note that in the
+descriptions of QUEUE_ORDERED_DRAIN*, '=>' is used whereas '->' is
+used for QUEUE_ORDERED_TAG* descriptions. '=>' indicates that the
+preceding step must be complete before proceeding to the next step.
+'->' indicates that the next step can start as soon as the previous
+step is issued.

+

+
+
+Random notes/caveats
+--------------------
+
+* SCSI layer currently can't use TAG ordering even if the drive,
+controller and driver support it. The problem is that SCSI midlayer
+request dispatch function is not atomic. It releases queue lock and
+switch to SCSI host lock during issue and it's possible and likely to
+happen in time that requests change their relative positions. Once
+this problem is solved, TAG ordering can be enabled.
+
+* Currently, no matter which ordered mode is used, there can be only
+one barrier request in progress. All I/O barriers are held off by
+block layer until the previous I/O barrier is complete. This doesn't
+make any difference for DRAIN ordered devices, but, for TAG ordered
+devices with very high command latency, passing multiple I/O barriers
+to low level *might* be helpful if they are very frequent. Well, this
+certainly is a non-issue. I'm writing this just to make clear that no
+two I/O barrier is ever passed to low-level driver.
+
+* Completion order. Requests in ordered sequence are issued in order
+but not required to finish in order. Barrier implementation can
+handle out-of-order completion of ordered sequence. IOW, the requests
+MUST be processed in order but the hardware/software completion paths
+are allowed to reorder completion notifications - eg. current SCSI
+midlayer doesn't preserve completion order during error handling.
+
+* Requeueing order. Low-level drivers are free to requeue any request
+after they removed it from the request queue with
+blkdev_dequeue_request(). As barrier sequence should be kept in order
+when requeued, generic elevator code takes care of putting requests in
+order around barrier. See blk_ordered_req_seq() and
+ELEVATOR_INSERT_REQUEUE handling in __elv_add_request() for details.
+
+Note that block drivers must not requeue preceding requests while
+completing latter requests in an ordered sequence. Currently, no
+error checking is done against this.
+
+* Error handling. Currently, block layer will report error to upper
+layer if any of requests in an ordered sequence fails. Unfortunately,
+this doesn't seem to be enough. Look at the following request flow.
+QUEUE_ORDERED_TAG_FLUSH is in use.
+
+ [0] [1] [2] [3] [pre] [barrier] [post] < [4] [5] [6] ... >
+ still in elevator
+
+Let's say request [2], [3] are write requests to update file system
+metadata (journal or whatever) and [barrier] is used to mark that
+those updates are valid. Consider the following sequence.
+
+ i. Requests [0] ~ [post] leaves the request queue and enters
+ low-level driver.
+ ii. After a while, unfortunately, something goes wrong and the
+ drive fails [2]. Note that any of [0], [1] and [3] could have
+ completed by this time, but [pre] couldn't have been finished
+ as the drive must process it in order and it failed before
+ processing that command.
+ iii. Error handling kicks in and determines that the error is
+ unrecoverable and fails [2], and resumes operation.
+ iv. [pre] [barrier] [post] gets processed.
+ v. *BOOM* power fails
+
+The problem here is that the barrier request is *supposed* to indicate
+that filesystem update requests [2] and [3] made it safely to the
+physical medium and, if the machine crashes after the barrier is
+written, filesystem recovery code can depend on that. Sadly, that
+isn't true in this case anymore. IOW, the success of a I/O barrier
+should also be dependent on success of some of the preceding requests,
+where only upper layer (filesystem) knows what 'some' is.
+
+This can be solved by implementing a way to tell the block layer which
+requests affect the success of the following barrier request and
+making lower lever drivers to resume operation on error only after
+block layer tells it to do so.
+
+As the probability of this happening is very low and the drive should
+be faulty, implementing the fix is probably an overkill. But, still,
+it's there.
+
+* In previous drafts of barrier implementation, there was fallback
+mechanism such that, if FUA or ordered TAG fails, less fancy ordered
+mode can be selected and the failed barrier request is retried
+automatically. The rationale for this feature was that as FUA is
+pretty new in ATA world and ordered tag was never used widely, there
+could be devices which report to support those features but choke when
+actually given such requests.
+
+ This was removed for two reasons 1. it's an overkill 2. it's
+impossible to implement properly when TAG ordering is used as low
+level drivers resume after an error automatically. If it's ever
+needed adding it back and modifying low level drivers accordingly
+shouldn't be difficult.

+Introduction
+
+Modern advances in system architectures have introduced advanced error
+reporting and correction capabilities in processors. CPU architectures permit
+partitioning support, where compute resources of a single CPU could be made
+available to virtual machine environments. There are couple OEMS that
+support NUMA hardware which are hot pluggable as well, where physical
+node insertion and removal require support for CPU hotplug.
+
+Such advances require CPUs available to a kernel to be removed either for
+provisioning reasons, or for RAS purposes to keep an offending CPU off
+system execution path. Hence the need for CPU hotplug support in the
+Linux kernel.
+
+A more novel use of CPU-hotplug support is its use today in suspend
+resume support for SMP. Dual-core and HT support makes even
+a laptop run SMP kernels which didn't support these methods. SMP support
+for suspend/resume is a work in progress.
+
+General Stuff about CPU Hotplug
+--------------------------------
+
+Command Line Switches
+---------------------
+maxcpus=n Restrict boot time cpus to n. Say if you have 4 cpus, using
+ maxcpus=2 will only boot 2. You can choose to bring the
+ other cpus later online, read FAQ's for more info.
+
+additional_cpus=n [x86_64 only] use this to limit hotpluggable cpus.
+ This option sets
+ cpu_possible_map = cpu_present_map + additional_cpus
+
+CPU maps and such
+-----------------
+[More on cpumaps and primitive to manipulate, please check
+include/linux/cpumask.h that has more descriptive text.]
+
+cpu_possible_map: Bitmap of possible CPUs that can ever be available in the
+system. This is used to allocate some boot time memory for per_cpu variables
+that aren't designed to grow/shrink as CPUs are made available or removed.
+Once set during boot time discovery phase, the map is static, i.e no bits
+are added or removed anytime. Trimming it accurately for your system needs
+upfront can save some boot time memory. See below for how we use heuristics
+in x86_64 case to keep this under check.
+
+cpu_online_map: Bitmap of all CPUs currently online. Its set in __cpu_up()
+after a cpu is available for kernel scheduling and ready to receive
+interrupts from devices. Its cleared when a cpu is brought down using
+__cpu_disable(), before which all OS services including interrupts are
+migrated to another target CPU.
+
+cpu_present_map: Bitmap of CPUs currently present in the system. Not all
+of them may be online. When physical hotplug is processed by the relevant
+subsystem (e.g ACPI) can change and new bit either be added or removed
+from the map depending on the event is hot-add/hot-remove. There are currently
+no locking rules as of now. Typical usage is to init topology during boot,
+at which time hotplug is disabled.
+
+You really dont need to manipulate any of the system cpu maps. They should
+be read-only for most use. When setting up per-cpu resources almost always use
+cpu_possible_map/for_each_cpu() to iterate.
+
+Never use anything other than cpumask_t to represent bitmap of CPUs.
+
+#include <linux/cpumask.h>
+
+for_each_cpu - Iterate over cpu_possible_map
+for_each_online_cpu - Iterate over cpu_online_map
+for_each_present_cpu - Iterate over cpu_present_map
+for_each_cpu_mask(x,mask) - Iterate over some random collection of cpu mask.
+
+#include <linux/cpu.h>
+lock_cpu_hotplug() and unlock_cpu_hotplug():
+
+The above calls are used to inhibit cpu hotplug operations. While holding the
+cpucontrol mutex, cpu_online_map will not change. If you merely need to avoid
+cpus going away, you could also use preempt_disable() and preempt_enable()
+for those sections. Just remember the critical section cannot call any
+function that can sleep or schedule this process away. The preempt_disable()
+will work as long as stop_machine_run() is used to take a cpu down.
+
+CPU Hotplug - Frequently Asked Questions.
+
+Q: How to i enable my kernel to support CPU hotplug?
+A: When doing make defconfig, Enable CPU hotplug support
+
+ "Processor type and Features" -> Support for Hotpluggable CPUs
+
+Make sure that you have CONFIG_HOTPLUG, and CONFIG_SMP turned on as well.
+
+You would need to enable CONFIG_HOTPLUG_CPU for SMP suspend/resume support
+as well.
+
+Q: What architectures support CPU hotplug?
+A: As of 2.6.14, the following architectures support CPU hotplug.
+
+i386 (Intel), ppc, ppc64, parisc, s390, ia64 and x86_64
+
+Q: How to test if hotplug is supported on the newly built kernel?
+A: You should now notice an entry in sysfs.
+
+Check if sysfs is mounted, using the "mount" command. You should notice
+an entry as shown below in the output.
+
+....
+none on /sys type sysfs (rw)
+....
+
+if this is not mounted, do the following.
+
+#mkdir /sysfs
+#mount -t sysfs sys /sys
+
+now you should see entries for all present cpu, the following is an example
+in a 8-way system.

+
+Under each directory you would find an "online" file which is the control
+file to logically online/offline a processor.
+
+Q: Does hot-add/hot-remove refer to physical add/remove of cpus?
+A: The usage of hot-add/remove may not be very consistently used in the code.
+CONFIG_CPU_HOTPLUG enables logical online/offline capability in the kernel.
+To support physical addition/removal, one would need some BIOS hooks and
+the platform should have something like an attention button in PCI hotplug.
+CONFIG_ACPI_HOTPLUG_CPU enables ACPI support for physical add/remove of CPUs.
+
+Q: How do i logically offline a CPU?
+A: Do the following.
+
+#echo 0 > /sys/devices/system/cpu/cpuX/online
+
+once the logical offline is successful, check
+
+#cat /proc/interrupts
+
+you should now not see the CPU that you removed. Also online file will report
+the state as 0 when a cpu if offline and 1 when its online.
+
+#To display the current cpu state.
+#cat /sys/devices/system/cpu/cpuX/online
+
+Q: Why cant i remove CPU0 on some systems?
+A: Some architectures may have some special dependency on a certain CPU.
+
+For e.g in IA64 platforms we have ability to sent platform interrupts to the
+OS. a.k.a Corrected Platform Error Interrupts (CPEI). In current ACPI
+specifications, we didn't have a way to change the target CPU. Hence if the
+current ACPI version doesn't support such re-direction, we disable that CPU
+by making it not-removable.
+
+In such cases you will also notice that the online file is missing under cpu0.
+
+Q: How do i find out if a particular CPU is not removable?
+A: Depending on the implementation, some architectures may show this by the
+absence of the "online" file. This is done if it can be determined ahead of
+time that this CPU cannot be removed.
+
+In some situations, this can be a run time check, i.e if you try to remove the
+last CPU, this will not be permitted. You can find such failures by
+investigating the return value of the "echo" command.
+
+Q: What happens when a CPU is being logically offlined?
+A: The following happen, listed in no particular order :-)
+
+- A notification is sent to in-kernel registered modules by sending an event
+ CPU_DOWN_PREPARE
+- All process is migrated away from this outgoing CPU to a new CPU
+- All interrupts targeted to this CPU is migrated to a new CPU
+- timers/bottom half/task lets are also migrated to a new CPU
+- Once all services are migrated, kernel calls an arch specific routine
+ __cpu_disable() to perform arch specific cleanup.
+- Once this is successful, an event for successful cleanup is sent by an event
+ CPU_DEAD.
+
+ "It is expected that each service cleans up when the CPU_DOWN_PREPARE
+ notifier is called, when CPU_DEAD is called its expected there is nothing
+ running on behalf of this CPU that was offlined"
+
+Q: If i have some kernel code that needs to be aware of CPU arrival and
+ departure, how to i arrange for proper notification?
+A: This is what you would need in your kernel code to receive notifications.
+
+ #include <linux/cpu.h>
+ static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
+ unsigned long action, void *hcpu)
+ {
+ unsigned int cpu = (unsigned long)hcpu;
+
+ switch (action) {
+ case CPU_ONLINE:
+ foobar_online_action(cpu);
+ break;
+ case CPU_DEAD:
+ foobar_dead_action(cpu);
+ break;
+ }
+ return NOTIFY_OK;
+ }
+
+ static struct notifier_block foobar_cpu_notifer =
+ {
+ .notifier_call = foobar_cpu_callback,
+ };
+
+
+In your init function,
+
+ register_cpu_notifier(&foobar_cpu_notifier);
+
+You can fail PREPARE notifiers if something doesn't work to prepare resources.
+This will stop the activity and send a following CANCELED event back.
+
+CPU_DEAD should not be failed, its just a goodness indication, but bad
+things will happen if a notifier in path sent a BAD notify code.
+
+Q: I don't see my action being called for all CPUs already up and running?
+A: Yes, CPU notifiers are called only when new CPUs are on-lined or offlined.
+ If you need to perform some action for each cpu already in the system, then
+
+ for_each_online_cpu(i) {
+ foobar_cpu_callback(&foobar_cpu_notifier, CPU_UP_PREPARE, i);
+ foobar_cpu_callback(&foobar-cpu_notifier, CPU_ONLINE, i);
+ }
+
+Q: If i would like to develop cpu hotplug support for a new architecture,
+ what do i need at a minimum?
+A: The following are what is required for CPU hotplug infrastructure to work
+ correctly.
+
+ - Make sure you have an entry in Kconfig to enable CONFIG_HOTPLUG_CPU
+ - __cpu_up() - Arch interface to bring up a CPU
+ - __cpu_disable() - Arch interface to shutdown a CPU, no more interrupts
+ can be handled by the kernel after the routine
+ returns. Including local APIC timers etc are
+ shutdown.
+ - __cpu_die() - This actually supposed to ensure death of the CPU.
+ Actually look at some example code in other arch
+ that implement CPU hotplug. The processor is taken
+ down from the idle() loop for that specific
+ architecture. __cpu_die() typically waits for some
+ per_cpu state to be set, to ensure the processor
+ dead routine is called to be sure positively.
+
+Q: I need to ensure that a particular cpu is not removed when there is some
+ work specific to this cpu is in progress.
+A: First switch the current thread context to preferred cpu
+
+ int my_func_on_cpu(int cpu)
+ {
+ cpumask_t saved_mask, new_mask = CPU_MASK_NONE;
+ int curr_cpu, err = 0;
+
+ saved_mask = current->cpus_allowed;
+ cpu_set(cpu, new_mask);
+ err = set_cpus_allowed(current, new_mask);
+
+ if (err)
+ return err;
+
+ /*
+ * If we got scheduled out just after the return from
+ * set_cpus_allowed() before running the work, this ensures
+ * we stay locked.
+ */
+ curr_cpu = get_cpu();
+
+ if (curr_cpu != cpu) {
+ err = -EAGAIN;
+ goto ret;
+ } else {
+ /*
+ * Do work : But cant sleep, since get_cpu() disables preempt
+ */
+ }
+ ret:
+ put_cpu();
+ set_cpus_allowed(current, saved_mask);
+ return err;
+ }
+
+
+Q: How do we determine how many CPUs are available for hotplug.
+A: There is no clear spec defined way from ACPI that can give us that
+ information today. Based on some input from Natalie of Unisys,
+ that the ACPI MADT (Multiple APIC Description Tables) marks those possible
+ CPUs in a system with disabled status.
+
+ Andi implemented some simple heuristics that count the number of disabled
+ CPUs in MADT as hotpluggable CPUS. In the case there are no disabled CPUS
+ we assume 1/2 the number of CPUs currently present can be hotplugged.
+
+ Caveat: Today's ACPI MADT can only provide 256 entries since the apicid field
+ in MADT is only 8 bits.
+
+User Space Notification
+
+Hotplug support for devices is common in Linux today. Its being used today to
+support automatic configuration of network, usb and pci devices. A hotplug
+event can be used to invoke an agent script to perform the configuration task.
+
+You can add /etc/hotplug/cpu.agent to handle hotplug notification user space
+scripts.
+
+ #!/bin/bash
+ # $Id: cpu.agent
+ # Kernel hotplug params include:
+ #ACTION=%s [online or offline]
+ #DEVPATH=%s
+ #
+ cd /etc/hotplug

+ echo `date` ":cpu.agent" add cpu >> /tmp/hotplug.txt

+ offline)
+ echo `date` ":cpu.agent" remove cpu >>/tmp/hotplug.txt

+1.4 What are exclusive cpusets ?
+--------------------------------
+
+If a cpuset is cpu or mem exclusive, no other cpuset, other than
+a direct ancestor or descendent, may share any of the same CPUs or
+Memory Nodes.
+
+A cpuset that is cpu_exclusive has a scheduler (sched) domain
+associated with it. The sched domain consists of all CPUs in the
+current cpuset that are not part of any exclusive child cpusets.
+This ensures that the scheduler load balancing code only balances
+against the CPUs that are in the sched domain as defined above and
+not all of the CPUs in the system. This removes any overhead due to
+load balancing code trying to pull tasks outside of the cpu_exclusive
+cpuset only to be prevented by the tasks' cpus_allowed mask.
+
+A cpuset that is mem_exclusive restricts kernel allocations for
+page, buffer and other data commonly shared by the kernel across
+multiple users. All cpusets, whether mem_exclusive or not, restrict
+allocations of memory for user space. This enables configuring a
+system so that several independent jobs can share common kernel data,
+such as file system pages, while isolating each jobs user allocation in
+its own cpuset. To do this, construct a large mem_exclusive cpuset to
+hold all the jobs, and construct child, non-mem_exclusive cpusets for
+each individual job. Only a small amount of typical kernel memory,
+such as requests from interrupt handlers, is allowed to be taken
+outside even a mem_exclusive cpuset.
+
+
+1.5 What does notify_on_release do ?
+------------------------------------
+
+If the notify_on_release flag is enabled (1) in a cpuset, then whenever
+the last task in the cpuset leaves (exits or attaches to some other
+cpuset) and the last child cpuset of that cpuset is removed, then
+the kernel runs the command /sbin/cpuset_release_agent, supplying the
+pathname (relative to the mount point of the cpuset file system) of the
+abandoned cpuset. This enables automatic removal of abandoned cpusets.
+The default value of notify_on_release in the root cpuset at system
+boot is disabled (0). The default value of other cpusets at creation
+is the current value of their parents notify_on_release setting.
+
+
+1.6 What is memory_pressure ?
+-----------------------------
+The memory_pressure of a cpuset provides a simple per-cpuset metric
+of the rate that the tasks in a cpuset are attempting to free up in
+use memory on the nodes of the cpuset to satisfy additional memory
+requests.
+
+This enables batch managers monitoring jobs running in dedicated
+cpusets to efficiently detect what level of memory pressure that job
+is causing.
+
+This is useful both on tightly managed systems running a wide mix of
+submitted jobs, which may choose to terminate or re-prioritize jobs that
+are trying to use more memory than allowed on the nodes assigned them,
+and with tightly coupled, long running, massively parallel scientific
+computing jobs that will dramatically fail to meet required performance
+goals if they start to use more memory than allowed to them.
+
+This mechanism provides a very economical way for the batch manager
+to monitor a cpuset for signs of memory pressure. It's up to the
+batch manager or other user code to decide what to do about it and
+take action.
+
+==> Unless this feature is enabled by writing "1" to the special file
+ /dev/cpuset/memory_pressure_enabled, the hook in the rebalance
+ code of __alloc_pages() for this metric reduces to simply noticing
+ that the cpuset_memory_pressure_enabled flag is zero. So only
+ systems that enable this feature will compute the metric.
+
+Why a per-cpuset, running average:
+
+ Because this meter is per-cpuset, rather than per-task or mm,
+ the system load imposed by a batch scheduler monitoring this
+ metric is sharply reduced on large systems, because a scan of
+ the tasklist can be avoided on each set of queries.
+
+ Because this meter is a running average, instead of an accumulating
+ counter, a batch scheduler can detect memory pressure with a
+ single read, instead of having to read and accumulate results
+ for a period of time.
+
+ Because this meter is per-cpuset rather than per-task or mm,
+ the batch scheduler can obtain the key information, memory
+ pressure in a cpuset, with a single read, rather than having to
+ query and accumulate results over all the (dynamically changing)
+ set of tasks in the cpuset.
+
+A per-cpuset simple digital filter (requires a spinlock and 3 words
+of data per-cpuset) is kept, and updated by any task attached to that
+cpuset, if it enters the synchronous (direct) page reclaim code.
+
+A per-cpuset file provides an integer number representing the recent
+(half-life of 10 seconds) rate of direct page reclaims caused by
+the tasks in the cpuset, in units of reclaims attempted per second,
+times 1000.

+EDAC - Error Detection And Correction
+
+Written by Doug Thompson <norsk5@xmission.com>
+7 Dec 2005
+
+
+EDAC was written by:
+ Thayne Harbaugh,
+ modified by Dave Peterson, Doug Thompson, et al,
+ from the bluesmoke.sourceforge.net project.
+
+
+============================================================================
+EDAC PURPOSE
+
+The 'edac' kernel module goal is to detect and report errors that occur
+within the computer system. In the initial release, memory Correctable Errors
+(CE) and Uncorrectable Errors (UE) are the primary errors being harvested.
+
+Detecting CE events, then harvesting those events and reporting them,
+CAN be a predictor of future UE events. With CE events, the system can
+continue to operate, but with less safety. Preventive maintainence and
+proactive part replacement of memory DIMMs exhibiting CEs can reduce
+the likelihood of the dreaded UE events and system 'panics'.
+
+
+In addition, PCI Bus Parity and SERR Errors are scanned for on PCI devices
+in order to determine if errors are occurring on data transfers.
+The presence of PCI Parity errors must be examined with a grain of salt.
+There are several addin adapters that do NOT follow the PCI specification
+with regards to Parity generation and reporting. The specification says
+the vendor should tie the parity status bits to 0 if they do not intend
+to generate parity. Some vendors do not do this, and thus the parity bit
+can "float" giving false positives.
+
+The PCI Parity EDAC device has the ability to "skip" known flakey
+cards during the parity scan. These are set by the parity "blacklist"
+interface in the sysfs for PCI Parity. (See the PCI section in the sysfs
+section below.) There is also a parity "whitelist" which is used as
+an explicit list of devices to scan, while the blacklist is a list
+of devices to skip.
+
+EDAC will have future error detectors that will be added or integrated
+into EDAC in the following list:
+
+ MCE Machine Check Exception
+ MCA Machine Check Architecture
+ NMI NMI notification of ECC errors
+ MSRs Machine Specific Register error cases
+ and other mechanisms.
+
+These errors are usually bus errors, ECC errors, thermal throttling
+and the like.
+
+
+============================================================================
+EDAC VERSIONING
+
+EDAC is composed of a "core" module (edac_mc.ko) and several Memory
+Controller (MC) driver modules. On a given system, the CORE
+is loaded and one MC driver will be loaded. Both the CORE and
+the MC driver have individual versions that reflect current release
+level of their respective modules. Thus, to "report" on what version
+a system is running, one must report both the CORE's and the
+MC driver's versions.
+
+
+LOADING
+
+If 'edac' was statically linked with the kernel then no loading is
+necessary. If 'edac' was built as modules then simply modprobe the
+'edac' pieces that you need. You should be able to modprobe
+hardware-specific modules and have the dependencies load the necessary core
+modules.
+
+Example:
+
+$> modprobe amd76x_edac
+
+loads both the amd76x_edac.ko memory controller module and the edac_mc.ko
+core module.
+
+
+============================================================================
+EDAC sysfs INTERFACE
+
+EDAC presents a 'sysfs' interface for control, reporting and attribute
+reporting purposes.
+
+EDAC lives in the /sys/devices/system/edac directory. Within this directory
+there currently reside 2 'edac' components:
+
+ mc memory controller(s) system
+ pci PCI status system
+
+
+============================================================================
+Memory Controller (mc) Model
+
+First a background on the memory controller's model abstracted in EDAC.
+Each mc device controls a set of DIMM memory modules. These modules are
+layed out in a Chip-Select Row (csrowX) and Channel table (chX). There can
+be multiple csrows and two channels.
+
+Memory controllers allow for several csrows, with 8 csrows being a typical value.
+Yet, the actual number of csrows depends on the electrical "loading"
+of a given motherboard, memory controller and DIMM characteristics.
+
+Dual channels allows for 128 bit data transfers to the CPU from memory.
+
+
+ Channel 0 Channel 1
+ ===================================
+ csrow0 | DIMM_A0 | DIMM_B0 |
+ csrow1 | DIMM_A0 | DIMM_B0 |
+ ===================================
+
+ ===================================
+ csrow2 | DIMM_A1 | DIMM_B1 |
+ csrow3 | DIMM_A1 | DIMM_B1 |
+ ===================================
+
+In the above example table there are 4 physical slots on the motherboard
+for memory DIMMs:
+
+ DIMM_A0
+ DIMM_B0
+ DIMM_A1
+ DIMM_B1
+
+Labels for these slots are usually silk screened on the motherboard. Slots
+labeled 'A' are channel 0 in this example. Slots labled 'B'
+are channel 1. Notice that there are two csrows possible on a
+physical DIMM. These csrows are allocated their csrow assignment
+based on the slot into which the memory DIMM is placed. Thus, when 1 DIMM
+is placed in each Channel, the csrows cross both DIMMs.
+
+Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
+Thus, 2 single ranked DIMMs, placed in slots DIMM_A0 and DIMM_B0 above
+will have 1 csrow, csrow0. csrow1 will be empty. On the other hand,
+when 2 dual ranked DIMMs are similiaryly placed, then both csrow0 and
+csrow1 will be populated. The pattern repeats itself for csrow2 and
+csrow3.
+
+The representation of the above is reflected in the directory tree
+in EDAC's sysfs interface. Starting in directory
+/sys/devices/system/edac/mc each memory controller will be represented
+by its own 'mcX' directory, where 'X" is the index of the MC.
+
+
+ ..../edac/mc/
+ |
+ |->mc0
+ |->mc1
+ |->mc2
+ ....
+
+Under each 'mcX' directory each 'csrowX' is again represented by a
+'csrowX', where 'X" is the csrow index:
+
+
+ .../mc/mc0/
+ |
+ |->csrow0
+ |->csrow2
+ |->csrow3
+ ....
+
+Notice that there is no csrow1, which indicates that csrow0 is
+composed of a single ranked DIMMs. This should also apply in both
+Channels, in order to have dual-channel mode be operational. Since
+both csrow2 and csrow3 are populated, this indicates a dual ranked
+set of DIMMs for channels 0 and 1.
+
+
+Within each of the 'mc','mcX' and 'csrowX' directories are several
+EDAC control and attribute files.
+
+
+============================================================================
+DIRECTORY 'mc'
+
+In directory 'mc' are EDAC system overall control and attribute files:
+
+
+Panic on UE control file:
+
+ 'panic_on_ue'
+
+ An uncorrectable error will cause a machine panic. This is usually
+ desirable. It is a bad idea to continue when an uncorrectable error
+ occurs - it is indeterminate what was uncorrected and the operating
+ system context might be so mangled that continuing will lead to further
+ corruption. If the kernel has MCE configured, then EDAC will never
+ notice the UE.

+

+ are reported through the system message log system. UE statistics
+ will be accumulated even when UE logging is disabled.

+
+============================================================================
+'mcX' DIRECTORIES
+
+
+In 'mcX' directories are EDAC control and attribute files for
+this 'X" instance of the memory controllers:
+
+
+Counter reset control file:
+
+ 'reset_counters'
+
+ This write-only control file will zero all the statistical counters
+ for UE and CE errors. Zeroing the counters will also reset the timer
+ indicating how long since the last counter zero. This is useful
+ for computing errors/time. Since the counters are always reset at
+ driver initialization time, no module/kernel parameter is available.
+
+ RUN TIME: echo "anything" >/sys/devices/system/edac/mc/mc0/counter_reset
+
+ This resets the counters on memory controller 0
+
+
+Seconds since last counter reset control file:
+
+ 'seconds_since_reset'
+
+ This attribute file displays how many seconds have elapsed since the
+ last counter reset. This can be used with the error counters to
+ measure error rates.
+
+
+
+DIMM capability attribute file:
+
+ 'edac_capability'
+
+ The EDAC (Error Detection and Correction) capabilities/modes of
+ the memory controller hardware.
+
+
+DIMM Current Capability attribute file:
+
+ 'edac_current_capability'
+
+ The EDAC capabilities available with the hardware
+ configuration. This may not be the same as "EDAC capability"
+ if the correct memory is not used. If a memory controller is
+ capable of EDAC, but DIMMs without check bits are in use, then
+ Parity, SECDED, S4ECD4ED capabilities will not be available
+ even though the memory controller might be capable of those
+ modes with the proper memory loaded.
+
+
+Memory Type supported on this controller attribute file:
+
+ 'supported_mem_type'
+
+ This attribute file displays the memory type, usually
+ buffered and unbuffered DIMMs.
+
+
+Memory Controller name attribute file:
+
+ 'mc_name'
+
+ This attribute file displays the type of memory controller
+ that is being utilized.
+
+
+Memory Controller Module name attribute file:
+
+ 'module_name'
+
+ This attribute file displays the memory controller module name,
+ version and date built. The name of the memory controller
+ hardware - some drivers work with multiple controllers and
+ this field shows which hardware is present.
+
+
+Total memory managed by this memory controller attribute file:
+
+ 'size_mb'
+
+ This attribute file displays, in count of megabytes, of memory
+ that this instance of memory controller manages.
+
+
+Total Uncorrectable Errors count attribute file:
+
+ 'ue_count'
+
+ This attribute file displays the total count of uncorrectable
+ errors that have occurred on this memory controller. If panic_on_ue
+ is set this counter will not have a chance to increment,
+ since EDAC will panic the system.
+
+
+Total UE count that had no information attribute fileY:
+
+ 'ue_noinfo_count'
+
+ This attribute file displays the number of UEs that
+ have occurred have occurred with no informations as to which DIMM
+ slot is having errors.
+
+
+Total Correctable Errors count attribute file:
+
+ 'ce_count'
+
+ This attribute file displays the total count of correctable
+ errors that have occurred on this memory controller. This
+ count is very important to examine. CEs provide early
+ indications that a DIMM is beginning to fail. This count
+ field should be monitored for non-zero values and report
+ such information to the system administrator.
+
+
+Total Correctable Errors count attribute file:
+
+ 'ce_noinfo_count'
+
+ This attribute file displays the number of CEs that
+ have occurred wherewith no informations as to which DIMM slot
+ is having errors. Memory is handicapped, but operational,
+ yet no information is available to indicate which slot
+ the failing memory is in. This count field should be also
+ be monitored for non-zero values.
+
+Device Symlink:
+
+ 'device'
+
+ Symlink to the memory controller device
+
+
+
+============================================================================
+'csrowX' DIRECTORIES
+
+In the 'csrowX' directories are EDAC control and attribute files for
+this 'X" instance of csrow:
+
+
+Total Uncorrectable Errors count attribute file:
+
+ 'ue_count'
+
+ This attribute file displays the total count of uncorrectable
+ errors that have occurred on this csrow. If panic_on_ue is set
+ this counter will not have a chance to increment, since EDAC
+ will panic the system.
+
+
+Total Correctable Errors count attribute file:
+
+ 'ce_count'
+
+ This attribute file displays the total count of correctable
+ errors that have occurred on this csrow. This
+ count is very important to examine. CEs provide early
+ indications that a DIMM is beginning to fail. This count
+ field should be monitored for non-zero values and report
+ such information to the system administrator.
+
+
+Total memory managed by this csrow attribute file:
+
+ 'size_mb'
+
+ This attribute file displays, in count of megabytes, of memory
+ that this csrow contatins.
+
+
+Memory Type attribute file:
+
+ 'mem_type'
+
+ This attribute file will display what type of memory is currently
+ on this csrow. Normally, either buffered or unbuffered memory.
+
+
+EDAC Mode of operation attribute file:
+
+ 'edac_mode'
+
+ This attribute file will display what type of Error detection
+ and correction is being utilized.
+
+
+Device type attribute file:
+
+ 'dev_type'
+
+ This attribute file will display what type of DIMM device is
+ being utilized. Example: x4
+
+
+Channel 0 CE Count attribute file:
+
+ 'ch0_ce_count'
+
+ This attribute file will display the count of CEs on this
+ DIMM located in channel 0.
+
+
+Channel 0 UE Count attribute file:
+
+ 'ch0_ue_count'
+
+ This attribute file will display the count of UEs on this
+ DIMM located in channel 0.
+
+
+Channel 0 DIMM Label control file:
+
+ 'ch0_dimm_label'
+
+ This control file allows this DIMM to have a label assigned
+ to it. With this label in the module, when errors occur
+ the output can provide the DIMM label in the system log.
+ This becomes vital for panic events to isolate the
+ cause of the UE event.
+
+ DIMM Labels must be assigned after booting, with information
+ that correctly identifies the physical slot with its
+ silk screen label. This information is currently very
+ motherboard specific and determination of this information
+ must occur in userland at this time.
+
+
+Channel 1 CE Count attribute file:
+
+ 'ch1_ce_count'
+
+ This attribute file will display the count of CEs on this
+ DIMM located in channel 1.
+
+
+Channel 1 UE Count attribute file:
+
+ 'ch1_ue_count'
+
+ This attribute file will display the count of UEs on this
+ DIMM located in channel 0.
+
+
+Channel 1 DIMM Label control file:
+
+ 'ch1_dimm_label'
+
+ This control file allows this DIMM to have a label assigned
+ to it. With this label in the module, when errors occur
+ the output can provide the DIMM label in the system log.
+ This becomes vital for panic events to isolate the
+ cause of the UE event.
+
+ DIMM Labels must be assigned after booting, with information
+ that correctly identifies the physical slot with its
+ silk screen label. This information is currently very
+ motherboard specific and determination of this information
+ must occur in userland at this time.
+
+
+============================================================================
+SYSTEM LOGGING
+
+If logging for UEs and CEs are enabled then system logs will have
+error notices indicating errors that have been detected:
+
+MC0: CE page 0x283, offset 0xce0, grain 8, syndrome 0x6ec3, row 0,
+channel 1 "DIMM_B1": amd76x_edac
+
+MC0: CE page 0x1e5, offset 0xfb0, grain 8, syndrome 0xb741, row 0,
+channel 1 "DIMM_B1": amd76x_edac
+
+
+The structure of the message is:
+ the memory controller (MC0)
+ Error type (CE)
+ memory page (0x283)
+ offset in the page (0xce0)
+ the byte granularity (grain 8)
+ or resolution of the error
+ the error syndrome (0xb741)
+ memory row (row 0)
+ memory channel (channel 1)
+ DIMM label, if set prior (DIMM B1
+ and then an optional, driver-specific message that may
+ have additional information.
+
+Both UEs and CEs with no info will lack all but memory controller,
+error type, a notice of "no info" and then an optional,
+driver-specific error message.
+
+
+
+============================================================================
+PCI Bus Parity Detection
+
+
+On Header Type 00 devices the primary status is looked at
+for any parity error regardless of whether Parity is enabled on the
+device. (The spec indicates parity is generated in some cases).
+On Header Type 01 bridges, the secondary status register is also
+looked at to see if parity ocurred on the bus on the other side of
+the bridge.
+
+
+SYSFS CONFIGURATION
+
+Under /sys/devices/system/edac/pci are control and attribute files as follows:
+
+
+Enable/Disable PCI Parity checking control file:
+
+ 'check_pci_parity'
+
+
+ This control file enables or disables the PCI Bus Parity scanning
+ operation. Writing a 1 to this file enables the scanning. Writing
+ a 0 to this file disables the scanning.
+
+ Enable:
+ echo "1" >/sys/devices/system/edac/pci/check_pci_parity
+
+ Disable:
+ echo "0" >/sys/devices/system/edac/pci/check_pci_parity
+
+
+
+Panic on PCI PARITY Error:
+
+ 'panic_on_pci_parity'
+
+
+ This control files enables or disables panic'ing when a parity
+ error has been detected.
+
+
+ module/kernel parameter: panic_on_pci_parity=[0|1]
+
+ Enable:
+ echo "1" >/sys/devices/system/edac/pci/panic_on_pci_parity
+
+ Disable:
+ echo "0" >/sys/devices/system/edac/pci/panic_on_pci_parity
+
+
+Parity Count:
+
+ 'pci_parity_count'
+
+ This attribute file will display the number of parity errors that
+ have been detected.
+
+
+
+PCI Device Whitelist:
+
+ 'pci_parity_whitelist'
+
+ This control file allows for an explicit list of PCI devices to be
+ scanned for parity errors. Only devices found on this list will
+ be examined. The list is a line of hexadecimel VENDOR and DEVICE
+ ID tuples:
+
+ 1022:7450,1434:16a6
+
+ One or more can be inserted, seperated by a comma.
+
+ To write the above list doing the following as one command line:
+
+ echo "1022:7450,1434:16a6"
+ > /sys/devices/system/edac/pci/pci_parity_whitelist
+
+
+
+ To display what the whitelist is, simply 'cat' the same file.
+
+
+PCI Device Blacklist:
+
+ 'pci_parity_blacklist'
+
+ This control file allows for a list of PCI devices to be
+ skipped for scanning.
+ The list is a line of hexadecimel VENDOR and DEVICE ID tuples:
+
+ 1022:7450,1434:16a6
+
+ One or more can be inserted, seperated by a comma.
+
+ To write the above list doing the following as one command line:
+
+ echo "1022:7450,1434:16a6"
+ > /sys/devices/system/edac/pci/pci_parity_blacklist
+
+
+ To display what the whitelist current contatins,
+ simply 'cat' the same file.
+
+=======================================================================
+
+PCI Vendor and Devices IDs can be obtained with the lspci command. Using
+the -n option lspci will display the vendor and device IDs. The system
+adminstrator will have to determine which devices should be scanned or
+skipped.
+
+
+
+The two lists (white and black) are prioritized. blacklist is the lower
+priority and will NOT be utilized when a whitelist has been set.
+Turn OFF a whitelist by an empty echo command:
+
+ echo > /sys/devices/system/edac/pci/pci_parity_whitelist
+
+and any previous blacklist will be utililzed.

+~~~~~
+
+FUSE sets up the following hierarchy in sysfs:
+
+ /sys/fs/fuse/connections/N/
+
+where N is an increasing number allocated to each new connection.
+
+For each connection the following attributes are defined:
+
+ 'waiting'
+
+ The number of requests which are waiting to be transfered to

+ filesystem is hung or deadlocked.
+
+ 'abort'
+
+ Writing anything into this file will abort the filesystem
+ connection. This means that all waiting requests will be aborted an

+
+Only a privileged user may read or write these attributes.
+
+Aborting a filesystem connection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to get into certain situations where the filesystem is
+not responding. Reasons for this may be:
+
+ a) Broken userspace filesystem implementation
+
+ b) Network connection down
+
+ c) Accidental deadlock
+
+ d) Malicious deadlock
+
+(For more on c) and d) see later sections)
+
+In either of these cases it may be useful to abort the connection to

+
+ - Kill the filesystem daemon. Works in case of a) and b)
+
+ - Kill the filesystem daemon and all users of the filesystem. Works
+ in all cases except some malicious deadlocks
+
+ - Use forced umount (umount -f). Works in all cases but only if
+ filesystem is still attached (it hasn't been lazy unmounted)

+Why cpio rather than tar?
+-------------------------
+
+This decision was made back in December, 2001. The discussion started here:
+
+ http://www.uwsg.iu.edu/hypermail/linux/kernel/0112.2/1538.html
+
+And spawned a second thread (specifically on tar vs cpio), starting here:
+
+ http://www.uwsg.iu.edu/hypermail/linux/kernel/0112.2/1587.html
+
+The quick and dirty summary version (which is no substitute for reading
+the above threads) is:
+
+1) cpio is a standard. It's decades old (from the AT&T days), and already
+ widely used on Linux (inside RPM, Red Hat's device driver disks). Here's
+ a Linux Journal article about it from 1996:
+
+ http://www.linuxjournal.com/article/1213
+
+ It's not as popular as tar because the traditional cpio command line tools
+ require _truly_hideous_ command line arguments. But that says nothing
+ either way about the archive format, and there are alternative tools,
+ such as:
+
+ http://freshmeat.net/projects/afio/
+
+2) The cpio archive format chosen by the kernel is simpler and cleaner (and
+ thus easier to create and parse) than any of the (literally dozens of)
+ various tar archive formats. The complete initramfs archive format is
+ explained in buffer-format.txt, created in usr/gen_init_cpio.c, and
+ extracted in init/initramfs.c. All three together come to less than 26k
+ total of human-readable text.
+
+3) The GNU project standardizing on tar is approximately as relevant as
+ Windows standardizing on zip. Linux is not part of either, and is free
+ to make its own technical decisions.
+
+4) Since this is a kernel internal format, it could easily have been
+ something brand new. The kernel provides its own tools to create and
+ extract this format anyway. Using an existing standard was preferable,
+ but not essential.
+
+5) Al Viro made the decision (quote: "tar is ugly as hell and not going to be
+ supported on the kernel side"):
+
+ http://www.uwsg.iu.edu/hypermail/linux/kernel/0112.2/1540.html

+Creating non-relay files
+------------------------
+
+relay_open() automatically creates files in the relayfs filesystem to
+represent the per-cpu kernel buffers; it's often useful for
+applications to be able to create their own files alongside the relay
+files in the relayfs filesystem as well e.g. 'control' files much like
+those created in /proc or debugfs for similar purposes, used to
+communicate control information between the kernel and user sides of a
+relayfs application. For this purpose the relayfs_create_file() and
+relayfs_remove_file() API functions exist. For relayfs_create_file(),
+the caller passes in a set of user-defined file operations to be used
+for the file and an optional void * to a user-specified data item,
+which will be accessible via inode->u.generic_ip (see the relay-apps
+tarball for examples). The file_operations are a required parameter
+to relayfs_create_file() and thus the semantics of these files are
+completely defined by the caller.
+
+See the relay-apps tarball at http://relayfs.sourceforge.net for
+examples of how these non-relay files are meant to be used.
+
+Creating relay files in other filesystems
+-----------------------------------------
+
+By default of course, relay_open() creates relay files in the relayfs
+filesystem. Because relay_file_operations is exported, however, it's
+also possible to create and use relay files in other pseudo-filesytems
+such as debugfs.
+
+For this purpose, two callback functions are provided,
+create_buf_file() and remove_buf_file(). create_buf_file() is called
+once for each per-cpu buffer from relay_open() to allow the client to
+create a file to be used to represent the corresponding buffer; if
+this callback is not defined, the default implementation will create
+and return a file in the relayfs filesystem to represent the buffer.
+The callback should return the dentry of the file created to represent
+the relay buffer. Note that the parent directory passed to
+relay_open() (and passed along to the callback), if specified, must
+exist in the same filesystem the new relay file is created in. If
+create_buf_file() is defined, remove_buf_file() must also be defined;
+it's responsible for deleting the file(s) created in create_buf_file()
+and is called during relay_close().
+
+The create_buf_file() implementation can also be defined in such a way
+as to allow the creation of a single 'global' buffer instead of the
+default per-cpu set. This can be useful for applications interested
+mainly in seeing the relative ordering of system-wide events without
+the need to bother with saving explicit timestamps for the purpose of
+merging/sorting per-cpu files in a postprocessing step.
+
+To have relay_open() create a global buffer, the create_buf_file()
+implementation should set the value of the is_global outparam to a
+non-zero value in addition to creating the file that will be used to
+represent the single buffer. In the case of a global buffer,
+create_buf_file() and remove_buf_file() will be called only once. The
+normal channel-writing functions e.g. relay_write() can still be used
+- writes from any cpu will transparently end up in the global buffer -
+but since it is a global buffer, callers should make sure they use the
+proper locking for such a buffer, either by wrapping writes in a
+spinlock, or by copying a write function from relayfs_fs.h and
+creating a local version that internally does the proper locking.
+
+See the 'exported-relayfile' examples in the relay-apps tarball for
+examples of creating and using relay files in debugfs.

+SPUFS(2) Linux Programmer's Manual SPUFS(2)
+
+
+
+NAME
+ spufs - the SPU file system
+
+
+DESCRIPTION
+ The SPU file system is used on PowerPC machines that implement the Cell
+ Broadband Engine Architecture in order to access Synergistic Processor
+ Units (SPUs).
+
+ The file system provides a name space similar to posix shared memory or
+ message queues. Users that have write permissions on the file system
+ can use spu_create(2) to establish SPU contexts in the spufs root.
+
+ Every SPU context is represented by a directory containing a predefined
+ set of files. These files can be used for manipulating the state of the
+ logical SPU. Users can change permissions on those files, but not actu-
+ ally add or remove files.
+
+
+MOUNT OPTIONS
+ uid=<uid>
+ set the user owning the mount point, the default is 0 (root).
+
+ gid=<gid>
+ set the group owning the mount point, the default is 0 (root).
+
+
+FILES
+ The files in spufs mostly follow the standard behavior for regular sys-
+ tem calls like read(2) or write(2), but often support only a subset of
+ the operations supported on regular file systems. This list details the
+ supported operations and the deviations from the behaviour in the
+ respective man pages.
+
+ All files that support the read(2) operation also support readv(2) and
+ all files that support the write(2) operation also support writev(2).
+ All files support the access(2) and stat(2) family of operations, but
+ only the st_mode, st_nlink, st_uid and st_gid fields of struct stat
+ contain reliable information.
+
+ All files support the chmod(2)/fchmod(2) and chown(2)/fchown(2) opera-
+ tions, but will not be able to grant permissions that contradict the
+ possible operations, e.g. read access on the wbox file.
+
+ The current set of files is:
+
+
+ /mem
+ the contents of the local storage memory of the SPU. This can be
+ accessed like a regular shared memory file and contains both code and
+ data in the address space of the SPU. The possible operations on an
+ open mem file are:
+
+ read(2), pread(2), write(2), pwrite(2), lseek(2)
+ These operate as documented, with the exception that seek(2),
+ write(2) and pwrite(2) are not supported beyond the end of the
+ file. The file size is the size of the local storage of the SPU,
+ which normally is 256 kilobytes.
+
+ mmap(2)
+ Mapping mem into the process address space gives access to the
+ SPU local storage within the process address space. Only
+ MAP_SHARED mappings are allowed.
+
+
+ /mbox
+ The first SPU to CPU communication mailbox. This file is read-only and
+ can be read in units of 32 bits. The file can only be used in non-
+ blocking mode and it even poll() will not block on it. The possible
+ operations on an open mbox file are:
+
+ read(2)
+ If a count smaller than four is requested, read returns -1 and
+ sets errno to EINVAL. If there is no data available in the mail
+ box, the return value is set to -1 and errno becomes EAGAIN.
+ When data has been read successfully, four bytes are placed in
+ the data buffer and the value four is returned.
+
+
+ /ibox
+ The second SPU to CPU communication mailbox. This file is similar to
+ the first mailbox file, but can be read in blocking I/O mode, and the
+ poll familiy of system calls can be used to wait for it. The possible
+ operations on an open ibox file are:
+
+ read(2)
+ If a count smaller than four is requested, read returns -1 and
+ sets errno to EINVAL. If there is no data available in the mail
+ box and the file descriptor has been opened with O_NONBLOCK, the
+ return value is set to -1 and errno becomes EAGAIN.
+
+ If there is no data available in the mail box and the file
+ descriptor has been opened without O_NONBLOCK, the call will
+ block until the SPU writes to its interrupt mailbox channel.
+ When data has been read successfully, four bytes are placed in
+ the data buffer and the value four is returned.
+
+ poll(2)
+ Poll on the ibox file returns (POLLIN | POLLRDNORM) whenever
+ data is available for reading.
+
+
+ /wbox
+ The CPU to SPU communation mailbox. It is write-only can can be written
+ in units of 32 bits. If the mailbox is full, write() will block and
+ poll can be used to wait for it becoming empty again. The possible
+ operations on an open wbox file are: write(2) If a count smaller than
+ four is requested, write returns -1 and sets errno to EINVAL. If there
+ is no space available in the mail box and the file descriptor has been
+ opened with O_NONBLOCK, the return value is set to -1 and errno becomes
+ EAGAIN.
+
+ If there is no space available in the mail box and the file descriptor
+ has been opened without O_NONBLOCK, the call will block until the SPU
+ reads from its PPE mailbox channel. When data has been read success-
+ fully, four bytes are placed in the data buffer and the value four is
+ returned.
+
+ poll(2)
+ Poll on the ibox file returns (POLLOUT | POLLWRNORM) whenever
+ space is available for writing.
+
+
+ /mbox_stat
+ /ibox_stat
+ /wbox_stat
+ Read-only files that contain the length of the current queue, i.e. how
+ many words can be read from mbox or ibox or how many words can be
+ written to wbox without blocking. The files can be read only in 4-byte
+ units and return a big-endian binary integer number. The possible
+ operations on an open *box_stat file are:
+
+ read(2)
+ If a count smaller than four is requested, read returns -1 and
+ sets errno to EINVAL. Otherwise, a four byte value is placed in
+ the data buffer, containing the number of elements that can be
+ read from (for mbox_stat and ibox_stat) or written to (for
+ wbox_stat) the respective mail box without blocking or resulting
+ in EAGAIN.
+
+
+ /npc
+ /decr
+ /decr_status
+ /spu_tag_mask
+ /event_mask
+ /srr0
+ Internal registers of the SPU. The representation is an ASCII string
+ with the numeric value of the next instruction to be executed. These
+ can be used in read/write mode for debugging, but normal operation of
+ programs should not rely on them because access to any of them except
+ npc requires an SPU context save and is therefore very inefficient.
+
+ The contents of these files are:
+
+ npc Next Program Counter
+
+ decr SPU Decrementer
+
+ decr_status Decrementer Status
+
+ spu_tag_mask MFC tag mask for SPU DMA
+
+ event_mask Event mask for SPU interrupts
+
+ srr0 Interrupt Return address register
+
+
+ The possible operations on an open npc, decr, decr_status,
+ spu_tag_mask, event_mask or srr0 file are:
+
+ read(2)
+ When the count supplied to the read call is shorter than the
+ required length for the pointer value plus a newline character,
+ subsequent reads from the same file descriptor will result in
+ completing the string, regardless of changes to the register by
+ a running SPU task. When a complete string has been read, all
+ subsequent read operations will return zero bytes and a new file
+ descriptor needs to be opened to read the value again.
+
+ write(2)
+ A write operation on the file results in setting the register to
+ the value given in the string. The string is parsed from the
+ beginning to the first non-numeric character or the end of the
+ buffer. Subsequent writes to the same file descriptor overwrite
+ the previous setting.
+
+
+ /fpcr
+ This file gives access to the Floating Point Status and Control Regis-
+ ter as a four byte long file. The operations on the fpcr file are:
+
+ read(2)
+ If a count smaller than four is requested, read returns -1 and
+ sets errno to EINVAL. Otherwise, a four byte value is placed in
+ the data buffer, containing the current value of the fpcr regis-
+ ter.
+
+ write(2)
+ If a count smaller than four is requested, write returns -1 and
+ sets errno to EINVAL. Otherwise, a four byte value is copied
+ from the data buffer, updating the value of the fpcr register.
+
+
+ /signal1
+ /signal2
+ The two signal notification channels of an SPU. These are read-write
+ files that operate on a 32 bit word. Writing to one of these files
+ triggers an interrupt on the SPU. The value writting to the signal
+ files can be read from the SPU through a channel read or from host user
+ space through the file. After the value has been read by the SPU, it
+ is reset to zero. The possible operations on an open signal1 or sig-
+ nal2 file are:
+
+ read(2)
+ If a count smaller than four is requested, read returns -1 and
+ sets errno to EINVAL. Otherwise, a four byte value is placed in
+ the data buffer, containing the current value of the specified
+ signal notification register.
+
+ write(2)
+ If a count smaller than four is requested, write returns -1 and
+ sets errno to EINVAL. Otherwise, a four byte value is copied
+ from the data buffer, updating the value of the specified signal
+ notification register. The signal notification register will
+ either be replaced with the input data or will be updated to the
+ bitwise OR or the old value and the input data, depending on the
+ contents of the signal1_type, or signal2_type respectively,
+ file.
+
+
+ /signal1_type
+ /signal2_type
+ These two files change the behavior of the signal1 and signal2 notifi-
+ cation files. The contain a numerical ASCII string which is read as
+ either "1" or "0". In mode 0 (overwrite), the hardware replaces the
+ contents of the signal channel with the data that is written to it. in
+ mode 1 (logical OR), the hardware accumulates the bits that are subse-
+ quently written to it. The possible operations on an open signal1_type
+ or signal2_type file are:
+
+ read(2)
+ When the count supplied to the read call is shorter than the
+ required length for the digit plus a newline character, subse-
+ quent reads from the same file descriptor will result in com-
+ pleting the string. When a complete string has been read, all
+ subsequent read operations will return zero bytes and a new file
+ descriptor needs to be opened to read the value again.
+
+ write(2)
+ A write operation on the file results in setting the register to
+ the value given in the string. The string is parsed from the
+ beginning to the first non-numeric character or the end of the
+ buffer. Subsequent writes to the same file descriptor overwrite
+ the previous setting.

+SPU_RUN(2) Linux Programmer's Manual SPU_RUN(2)
+
+
+
+NAME
+ spu_run - execute an spu context
+
+
+SYNOPSIS
+ #include <sys/spu.h>
+
+ int spu_run(int fd, unsigned int *npc, unsigned int *event);
+
+DESCRIPTION
+ The spu_run system call is used on PowerPC machines that implement the
+ Cell Broadband Engine Architecture in order to access Synergistic Pro-
+ cessor Units (SPUs). It uses the fd that was returned from spu_cre-
+ ate(2) to address a specific SPU context. When the context gets sched-
+ uled to a physical SPU, it starts execution at the instruction pointer
+ passed in npc.
+
+ Execution of SPU code happens synchronously, meaning that spu_run does
+ not return while the SPU is still running. If there is a need to exe-
+ cute SPU code in parallel with other code on either the main CPU or
+ other SPUs, you need to create a new thread of execution first, e.g.
+ using the pthread_create(3) call.
+
+ When spu_run returns, the current value of the SPU instruction pointer
+ is written back to npc, so you can call spu_run again without updating
+ the pointers.
+
+ event can be a NULL pointer or point to an extended status code that
+ gets filled when spu_run returns. It can be one of the following con-
+ stants:
+
+ SPE_EVENT_DMA_ALIGNMENT
+ A DMA alignment error
+
+ SPE_EVENT_SPE_DATA_SEGMENT
+ A DMA segmentation error
+
+ SPE_EVENT_SPE_DATA_STORAGE
+ A DMA storage error
+
+ If NULL is passed as the event argument, these errors will result in a
+ signal delivered to the calling process.
+
+RETURN VALUE
+ spu_run returns the value of the spu_status register or -1 to indicate
+ an error and set errno to one of the error codes listed below. The
+ spu_status register value contains a bit mask of status codes and
+ optionally a 14 bit code returned from the stop-and-signal instruction
+ on the SPU. The bit masks for the status codes are:
+
+ 0x02 SPU was stopped by stop-and-signal.
+
+ 0x04 SPU was stopped by halt.
+
+ 0x08 SPU is waiting for a channel.
+
+ 0x10 SPU is in single-step mode.
+
+ 0x20 SPU has tried to execute an invalid instruction.
+
+ 0x40 SPU has tried to access an invalid channel.
+
+ 0x3fff0000
+ The bits masked with this value contain the code returned from
+ stop-and-signal.
+
+ There are always one or more of the lower eight bits set or an error
+ code is returned from spu_run.
+
+ERRORS
+ EAGAIN or EWOULDBLOCK
+ fd is in non-blocking mode and spu_run would block.
+
+ EBADF fd is not a valid file descriptor.
+
+ EFAULT npc is not a valid pointer or status is neither NULL nor a valid

+
+
+SYNOPSIS
+ #include <sys/types.h>
+ #include <sys/spu.h>
+
+ int spu_create(const char *pathname, int flags, mode_t mode);
+
+DESCRIPTION
+ The spu_create system call is used on PowerPC machines that implement
+ the Cell Broadband Engine Architecture in order to access Synergistic
+ Processor Units (SPUs). It creates a new logical context for an SPU in
+ pathname and returns a handle to associated with it. pathname must
+ point to a non-existing directory in the mount point of the SPU file
+ system (spufs). When spu_create is successful, a directory gets cre-
+ ated on pathname and it is populated with files.
+
+ The returned file handle can only be passed to spu_run(2) or closed,
+ other operations are not defined on it. When it is closed, all associ-
+ ated directory entries in spufs are removed. When the last file handle
+ pointing either inside of the context directory or to this file
+ descriptor is closed, the logical SPU context is destroyed.
+
+ The parameter flags can be zero or any bitwise or'd combination of the
+ following constants:
+
+ SPU_RAWIO
+ Allow mapping of some of the hardware registers of the SPU into
+ user space. This flag requires the CAP_SYS_RAWIO capability, see
+ capabilities(7).
+
+ The mode parameter specifies the permissions used for creating the new
+ directory in spufs. mode is modified with the user's umask(2) value
+ and then used for both the directory and the files contained in it. The
+ file permissions mask out some more bits of mode because they typically
+ support only read or write access. See stat(2) for a full list of the
+ possible mode values.
+
+
+RETURN VALUE
+ spu_create returns a new file descriptor. It may return -1 to indicate
+ an error condition and set errno to one of the error codes listed
+ below.
+
+
+ERRORS
+ EACCESS
+ The current user does not have write access on the spufs mount
+ point.
+
+ EEXIST An SPU context already exists at the given path name.
+
+ EFAULT pathname is not a valid string pointer in the current address
+ space.
+
+ EINVAL pathname is not a directory in the spufs mount point.
+
+ ELOOP Too many symlinks were found while resolving pathname.
+
+ EMFILE The process has reached its maximum open file limit.
+
+ ENAMETOOLONG
+ pathname was too long.
+
+ ENFILE The system has reached the global open file limit.
+
+ ENOENT Part of pathname could not be resolved.
+
+ ENOMEM The kernel could not allocate all resources required.
+
+ ENOSPC There are not enough SPU resources available to create a new
+ context or the user specific limit for the number of SPU con-
+ texts has been reached.

+hrtimers - subsystem for high-resolution kernel timers
+----------------------------------------------------
+
+This patch introduces a new subsystem for high-resolution kernel timers.
+
+One might ask the question: we already have a timer subsystem
+(kernel/timers.c), why do we need two timer subsystems? After a lot of
+back and forth trying to integrate high-resolution and high-precision
+features into the existing timer framework, and after testing various
+such high-resolution timer implementations in practice, we came to the
+conclusion that the timer wheel code is fundamentally not suitable for
+such an approach. We initially didnt believe this ('there must be a way
+to solve this'), and spent a considerable effort trying to integrate
+things into the timer wheel, but we failed. In hindsight, there are
+several reasons why such integration is hard/impossible:
+
+- the forced handling of low-resolution and high-resolution timers in
+ the same way leads to a lot of compromises, macro magic and #ifdef
+ mess. The timers.c code is very "tightly coded" around jiffies and
+ 32-bitness assumptions, and has been honed and micro-optimized for a
+ relatively narrow use case (jiffies in a relatively narrow HZ range)
+ for many years - and thus even small extensions to it easily break
+ the wheel concept, leading to even worse compromises. The timer wheel
+ code is very good and tight code, there's zero problems with it in its
+ current usage - but it is simply not suitable to be extended for
+ high-res timers.
+
+- the unpredictable [O(N)] overhead of cascading leads to delays which
+ necessiate a more complex handling of high resolution timers, which
+ in turn decreases robustness. Such a design still led to rather large
+ timing inaccuracies. Cascading is a fundamental property of the timer
+ wheel concept, it cannot be 'designed out' without unevitably
+ degrading other portions of the timers.c code in an unacceptable way.
+
+- the implementation of the current posix-timer subsystem on top of
+ the timer wheel has already introduced a quite complex handling of
+ the required readjusting of absolute CLOCK_REALTIME timers at
+ settimeofday or NTP time - further underlying our experience by
+ example: that the timer wheel data structure is too rigid for high-res
+ timers.
+
+- the timer wheel code is most optimal for use cases which can be
+ identified as "timeouts". Such timeouts are usually set up to cover
+ error conditions in various I/O paths, such as networking and block
+ I/O. The vast majority of those timers never expire and are rarely
+ recascaded because the expected correct event arrives in time so they
+ can be removed from the timer wheel before any further processing of
+ them becomes necessary. Thus the users of these timeouts can accept
+ the granularity and precision tradeoffs of the timer wheel, and
+ largely expect the timer subsystem to have near-zero overhead.
+ Accurate timing for them is not a core purpose - in fact most of the
+ timeout values used are ad-hoc. For them it is at most a necessary
+ evil to guarantee the processing of actual timeout completions
+ (because most of the timeouts are deleted before completion), which
+ should thus be as cheap and unintrusive as possible.
+
+The primary users of precision timers are user-space applications that
+utilize nanosleep, posix-timers and itimer interfaces. Also, in-kernel
+users like drivers and subsystems which require precise timed events
+(e.g. multimedia) can benefit from the availability of a seperate
+high-resolution timer subsystem as well.
+
+While this subsystem does not offer high-resolution clock sources just
+yet, the hrtimer subsystem can be easily extended with high-resolution
+clock capabilities, and patches for that exist and are maturing quickly.
+The increasing demand for realtime and multimedia applications along
+with other potential users for precise timers gives another reason to
+separate the "timeout" and "precise timer" subsystems.
+
+Another potential benefit is that such a seperation allows even more
+special-purpose optimization of the existing timer wheel for the low
+resolution and low precision use cases - once the precision-sensitive
+APIs are separated from the timer wheel and are migrated over to
+hrtimers. E.g. we could decrease the frequency of the timeout subsystem
+from 250 Hz to 100 HZ (or even smaller).
+
+hrtimer subsystem implementation details
+----------------------------------------
+
+the basic design considerations were:
+
+- simplicity
+
+- data structure not bound to jiffies or any other granularity. All the
+ kernel logic works at 64-bit nanoseconds resolution - no compromises.
+
+- simplification of existing, timing related kernel code
+
+another basic requirement was the immediate enqueueing and ordering of
+timers at activation time. After looking at several possible solutions
+such as radix trees and hashes, we chose the red black tree as the basic
+data structure. Rbtrees are available as a library in the kernel and are
+used in various performance-critical areas of e.g. memory management and
+file systems. The rbtree is solely used for time sorted ordering, while
+a separate list is used to give the expiry code fast access to the
+queued timers, without having to walk the rbtree.
+
+(This seperate list is also useful for later when we'll introduce
+high-resolution clocks, where we need seperate pending and expired
+queues while keeping the time-order intact.)
+
+Time-ordered enqueueing is not purely for the purposes of
+high-resolution clocks though, it also simplifies the handling of
+absolute timers based on a low-resolution CLOCK_REALTIME. The existing
+implementation needed to keep an extra list of all armed absolute
+CLOCK_REALTIME timers along with complex locking. In case of
+settimeofday and NTP, all the timers (!) had to be dequeued, the
+time-changing code had to fix them up one by one, and all of them had to
+be enqueued again. The time-ordered enqueueing and the storage of the
+expiry time in absolute time units removes all this complex and poorly
+scaling code from the posix-timer implementation - the clock can simply
+be set without having to touch the rbtree. This also makes the handling
+of posix-timers simpler in general.
+
+The locking and per-CPU behavior of hrtimers was mostly taken from the
+existing timer wheel code, as it is mature and well suited. Sharing code
+was not really a win, due to the different data structures. Also, the
+hrtimer functions now have clearer behavior and clearer names - such as
+hrtimer_try_to_cancel() and hrtimer_cancel() [which are roughly
+equivalent to del_timer() and del_timer_sync()] - so there's no direct
+1:1 mapping between them on the algorithmical level, and thus no real
+potential for code sharing either.
+
+Basic data types: every time value, absolute or relative, is in a
+special nanosecond-resolution type: ktime_t. The kernel-internal
+representation of ktime_t values and operations is implemented via
+macros and inline functions, and can be switched between a "hybrid
+union" type and a plain "scalar" 64bit nanoseconds representation (at
+compile time). The hybrid union type optimizes time conversions on 32bit
+CPUs. This build-time-selectable ktime_t storage format was implemented
+to avoid the performance impact of 64-bit multiplications and divisions
+on 32bit CPUs. Such operations are frequently necessary to convert
+between the storage formats provided by kernel and userspace interfaces
+and the internal time format. (See include/linux/ktime.h for further
+details.)
+
+hrtimers - rounding of timer values
+-----------------------------------
+
+the hrtimer code will round timer events to lower-resolution clocks
+because it has to. Otherwise it will do no artificial rounding at all.
+
+one question is, what resolution value should be returned to the user by
+the clock_getres() interface. This will return whatever real resolution
+a given clock has - be it low-res, high-res, or artificially-low-res.
+
+hrtimers - testing and verification
+----------------------------------
+
+We used the high-resolution clock subsystem ontop of hrtimers to verify
+the hrtimer implementation details in praxis, and we also ran the posix
+timer tests in order to ensure specification compliance. We also ran
+tests on low-resolution clocks.
+
+The hrtimer patch converts the following kernel functionality to use
+hrtimers:
+
+ - nanosleep
+ - itimers
+ - posix-timers
+
+The conversion of nanosleep and posix-timers enabled the unification of
+nanosleep and clock_nanosleep.
+
+The code was successfully compiled for the following platforms:
+
+ i386, x86_64, ARM, PPC, PPC64, IA64
+
+The code was run-tested on the following platforms:
+
+ i386(UP/SMP), x86_64(UP/SMP), ARM, PPC
+
+hrtimers were also integrated into the -rt tree, along with a
+hrtimers-based high-resolution clock implementation, so the hrtimers
+code got a healthy amount of testing and use in practice.

+Generic Mutex Subsystem
+
+started by Ingo Molnar <mingo@redhat.com>
+
+ "Why on earth do we need a new mutex subsystem, and what's wrong
+ with semaphores?"
+
+firstly, there's nothing wrong with semaphores. But if the simpler
+mutex semantics are sufficient for your code, then there are a couple
+of advantages of mutexes:
+
+ - 'struct mutex' is smaller on most architectures: .e.g on x86,
+ 'struct semaphore' is 20 bytes, 'struct mutex' is 16 bytes.
+ A smaller structure size means less RAM footprint, and better
+ CPU-cache utilization.
+
+ - tighter code. On x86 i get the following .text sizes when
+ switching all mutex-alike semaphores in the kernel to the mutex
+ subsystem:
+
+ text data bss dec hex filename
+ 3280380 868188 396860 4545428 455b94 vmlinux-semaphore
+ 3255329 865296 396732 4517357 44eded vmlinux-mutex
+
+ that's 25051 bytes of code saved, or a 0.76% win - off the hottest
+ codepaths of the kernel. (The .data savings are 2892 bytes, or 0.33%)
+ Smaller code means better icache footprint, which is one of the
+ major optimization goals in the Linux kernel currently.
+
+ - the mutex subsystem is slightly faster and has better scalability for
+ contended workloads. On an 8-way x86 system, running a mutex-based
+ kernel and testing creat+unlink+close (of separate, per-task files)
+ in /tmp with 16 parallel tasks, the average number of ops/sec is:
+
+ Semaphores: Mutexes:
+
+ $ ./test-mutex V 16 10 $ ./test-mutex V 16 10
+ 8 CPUs, running 16 tasks. 8 CPUs, running 16 tasks.
+ checking VFS performance. checking VFS performance.
+ avg loops/sec: 34713 avg loops/sec: 84153
+ CPU utilization: 63% CPU utilization: 22%
+
+ i.e. in this workload, the mutex based kernel was 2.4 times faster
+ than the semaphore based kernel, _and_ it also had 2.8 times less CPU
+ utilization. (In terms of 'ops per CPU cycle', the semaphore kernel
+ performed 551 ops/sec per 1% of CPU time used, while the mutex kernel
+ performed 3825 ops/sec per 1% of CPU time used - it was 6.9 times
+ more efficient.)
+
+ the scalability difference is visible even on a 2-way P4 HT box:
+
+ Semaphores: Mutexes:
+
+ $ ./test-mutex V 16 10 $ ./test-mutex V 16 10
+ 4 CPUs, running 16 tasks. 8 CPUs, running 16 tasks.
+ checking VFS performance. checking VFS performance.
+ avg loops/sec: 127659 avg loops/sec: 181082
+ CPU utilization: 100% CPU utilization: 34%
+
+ (the straight performance advantage of mutexes is 41%, the per-cycle
+ efficiency of mutexes is 4.1 times better.)
+
+ - there are no fastpath tradeoffs, the mutex fastpath is just as tight
+ as the semaphore fastpath. On x86, the locking fastpath is 2
+ instructions:
+
+ c0377ccb <mutex_lock>:
+ c0377ccb: f0 ff 08 lock decl (%eax)
+ c0377cce: 78 0e js c0377cde <.text.lock.mutex>
+ c0377cd0: c3 ret
+
+ the unlocking fastpath is equally tight:
+
+ c0377cd1 <mutex_unlock>:
+ c0377cd1: f0 ff 00 lock incl (%eax)
+ c0377cd4: 7e 0f jle c0377ce5 <.text.lock.mutex+0x7>
+ c0377cd6: c3 ret
+
+ - 'struct mutex' semantics are well-defined and are enforced if
+ CONFIG_DEBUG_MUTEXES is turned on. Semaphores on the other hand have
+ virtually no debugging code or instrumentation. The mutex subsystem
+ checks and enforces the following rules:
+
+ * - only one task can hold the mutex at a time
+ * - only the owner can unlock the mutex
+ * - multiple unlocks are not permitted
+ * - recursive locking is not permitted
+ * - a mutex object must be initialized via the API
+ * - a mutex object must not be initialized via memset or copying
+ * - task may not exit with mutex held
+ * - memory areas where held locks reside must not be freed
+ * - held mutexes must not be reinitialized
+ * - mutexes may not be used in irq contexts
+
+ furthermore, there are also convenience features in the debugging
+ code:
+
+ * - uses symbolic names of mutexes, whenever they are printed in debug output
+ * - point-of-acquire tracking, symbolic lookup of function names
+ * - list of all locks held in the system, printout of them
+ * - owner tracking
+ * - detects self-recursing locks and prints out all relevant info
+ * - detects multi-task circular deadlocks and prints out all affected
+ * locks and tasks (and only those tasks)
+
+Disadvantages
+-------------
+
+The stricter mutex API means you cannot use mutexes the same way you
+can use semaphores: e.g. they cannot be used from an interrupt context,
+nor can they be unlocked from a different context that which acquired
+it. [ I'm not aware of any other (e.g. performance) disadvantages from
+using mutexes at the moment, please let me know if you find any. ]
+
+Implementation of mutexes
+-------------------------
+
+'struct mutex' is the new mutex type, defined in include/linux/mutex.h
+and implemented in kernel/mutex.c. It is a counter-based mutex with a
+spinlock and a wait-list. The counter has 3 states: 1 for "unlocked",
+0 for "locked" and negative numbers (usually -1) for "locked, potential
+waiters queued".
+
+the APIs of 'struct mutex' have been streamlined:
+
+ DEFINE_MUTEX(name);
+
+ mutex_init(mutex);
+
+ void mutex_lock(struct mutex *lock);
+ int mutex_lock_interruptible(struct mutex *lock);
+ int mutex_trylock(struct mutex *lock);
+ void mutex_unlock(struct mutex *lock);
+ int mutex_is_locked(struct mutex *lock);

+ PCI Error Recovery
+ ------------------
+ May 31, 2005
+
+ Current document maintainer:
+ Linas Vepstas <linas@austin.ibm.com>
+
+
+Some PCI bus controllers are able to detect certain "hard" PCI errors
+on the bus, such as parity errors on the data and address busses, as
+well as SERR and PERR errors. These chipsets are then able to disable
+I/O to/from the affected device, so that, for example, a bad DMA
+address doesn't end up corrupting system memory. These same chipsets
+are also able to reset the affected PCI device, and return it to
+working condition. This document describes a generic API form
+performing error recovery.
+
+The core idea is that after a PCI error has been detected, there must
+be a way for the kernel to coordinate with all affected device drivers
+so that the pci card can be made operational again, possibly after
+performing a full electrical #RST of the PCI card. The API below
+provides a generic API for device drivers to be notified of PCI
+errors, and to be notified of, and respond to, a reset sequence.
+
+Preliminary sketch of API, cut-n-pasted-n-modified email from
+Ben Herrenschmidt, circa 5 april 2005
+
+The error recovery API support is exposed to the driver in the form of
+a structure of function pointers pointed to by a new field in struct
+pci_driver. The absence of this pointer in pci_driver denotes an
+"non-aware" driver, behaviour on these is platform dependant.
+Platforms like ppc64 can try to simulate pci hotplug remove/add.
+
+The definition of "pci_error_token" is not covered here. It is based on
+Seto's work on the synchronous error detection. We still need to define
+functions for extracting infos out of an opaque error token. This is
+separate from this API.
+
+This structure has the form:
+
+struct pci_error_handlers
+{
+ int (*error_detected)(struct pci_dev *dev, pci_error_token error);
+ int (*mmio_enabled)(struct pci_dev *dev);
+ int (*resume)(struct pci_dev *dev);
+ int (*link_reset)(struct pci_dev *dev);
+ int (*slot_reset)(struct pci_dev *dev);
+};
+
+A driver doesn't have to implement all of these callbacks. The
+only mandatory one is error_detected(). If a callback is not
+implemented, the corresponding feature is considered unsupported.
+For example, if mmio_enabled() and resume() aren't there, then the
+driver is assumed as not doing any direct recovery and requires
+a reset. If link_reset() is not implemented, the card is assumed as
+not caring about link resets, in which case, if recover is supported,
+the core can try recover (but not slot_reset() unless it really did
+reset the slot). If slot_reset() is not supported, link_reset() can
+be called instead on a slot reset.
+
+At first, the call will always be :
+
+ 1) error_detected()
+
+ Error detected. This is sent once after an error has been detected. At
+this point, the device might not be accessible anymore depending on the
+platform (the slot will be isolated on ppc64). The driver may already
+have "noticed" the error because of a failing IO, but this is the proper
+"synchronisation point", that is, it gives a chance to the driver to
+cleanup, waiting for pending stuff (timers, whatever, etc...) to
+complete; it can take semaphores, schedule, etc... everything but touch
+the device. Within this function and after it returns, the driver
+shouldn't do any new IOs. Called in task context. This is sort of a
+"quiesce" point. See note about interrupts at the end of this doc.
+
+ Result codes:
+ - PCIERR_RESULT_CAN_RECOVER:
+ Driever returns this if it thinks it might be able to recover
+ the HW by just banging IOs or if it wants to be given
+ a chance to extract some diagnostic informations (see
+ below).
+ - PCIERR_RESULT_NEED_RESET:
+ Driver returns this if it thinks it can't recover unless the
+ slot is reset.
+ - PCIERR_RESULT_DISCONNECT:
+ Return this if driver thinks it won't recover at all,
+ (this will detach the driver ? or just leave it
+ dangling ? to be decided)
+
+So at this point, we have called error_detected() for all drivers
+on the segment that had the error. On ppc64, the slot is isolated. What
+happens now typically depends on the result from the drivers. If all
+drivers on the segment/slot return PCIERR_RESULT_CAN_RECOVER, we would
+re-enable IOs on the slot (or do nothing special if the platform doesn't
+isolate slots) and call 2). If not and we can reset slots, we go to 4),
+if neither, we have a dead slot. If it's an hotplug slot, we might
+"simulate" reset by triggering HW unplug/replug though.
+
+>>> Current ppc64 implementation assumes that a device driver will
+>>> *not* schedule or semaphore in this routine; the current ppc64
+>>> implementation uses one kernel thread to notify all devices;
+>>> thus, of one device sleeps/schedules, all devices are affected.
+>>> Doing better requires complex multi-threaded logic in the error
+>>> recovery implementation (e.g. waiting for all notification threads
+>>> to "join" before proceeding with recovery.) This seems excessively
+>>> complex and not worth implementing.
+
+>>> The current ppc64 implementation doesn't much care if the device
+>>> attempts i/o at this point, or not. I/O's will fail, returning
+>>> a value of 0xff on read, and writes will be dropped. If the device
+>>> driver attempts more than 10K I/O's to a frozen adapter, it will
+>>> assume that the device driver has gone into an infinite loop, and
+>>> it will panic the the kernel.
+
+ 2) mmio_enabled()
+
+ This is the "early recovery" call. IOs are allowed again, but DMA is
+not (hrm... to be discussed, I prefer not), with some restrictions. This
+is NOT a callback for the driver to start operations again, only to
+peek/poke at the device, extract diagnostic information, if any, and
+eventually do things like trigger a device local reset or some such,
+but not restart operations. This is sent if all drivers on a segment
+agree that they can try to recover and no automatic link reset was
+performed by the HW. If the platform can't just re-enable IOs without
+a slot reset or a link reset, it doesn't call this callback and goes
+directly to 3) or 4). All IOs should be done _synchronously_ from
+within this callback, errors triggered by them will be returned via
+the normal pci_check_whatever() api, no new error_detected() callback
+will be issued due to an error happening here. However, such an error
+might cause IOs to be re-blocked for the whole segment, and thus
+invalidate the recovery that other devices on the same segment might
+have done, forcing the whole segment into one of the next states,
+that is link reset or slot reset.
+
+ Result codes:
+ - PCIERR_RESULT_RECOVERED
+ Driver returns this if it thinks the device is fully
+ functionnal and thinks it is ready to start
+ normal driver operations again. There is no
+ guarantee that the driver will actually be
+ allowed to proceed, as another driver on the
+ same segment might have failed and thus triggered a
+ slot reset on platforms that support it.
+
+ - PCIERR_RESULT_NEED_RESET
+ Driver returns this if it thinks the device is not
+ recoverable in it's current state and it needs a slot
+ reset to proceed.
+
+ - PCIERR_RESULT_DISCONNECT
+ Same as above. Total failure, no recovery even after
+ reset driver dead. (To be defined more precisely)
+
+>>> The current ppc64 implementation does not implement this callback.
+
+ 3) link_reset()
+
+ This is called after the link has been reset. This is typically
+a PCI Express specific state at this point and is done whenever a
+non-fatal error has been detected that can be "solved" by resetting
+the link. This call informs the driver of the reset and the driver
+should check if the device appears to be in working condition.
+This function acts a bit like 2) mmio_enabled(), in that the driver
+is not supposed to restart normal driver I/O operations right away.
+Instead, it should just "probe" the device to check it's recoverability
+status. If all is right, then the core will call resume() once all
+drivers have ack'd link_reset().
+
+ Result codes:
+ (identical to mmio_enabled)
+
+>>> The current ppc64 implementation does not implement this callback.
+
+ 4) slot_reset()
+
+ This is called after the slot has been soft or hard reset by the
+platform. A soft reset consists of asserting the adapter #RST line
+and then restoring the PCI BARs and PCI configuration header. If the
+platform supports PCI hotplug, then it might instead perform a hard
+reset by toggling power on the slot off/on. This call gives drivers
+the chance to re-initialize the hardware (re-download firmware, etc.),
+but drivers shouldn't restart normal I/O processing operations at
+this point. (See note about interrupts; interrupts aren't guaranteed
+to be delivered until the resume() callback has been called). If all
+device drivers report success on this callback, the patform will call
+resume() to complete the error handling and let the driver restart
+normal I/O processing.
+
+A driver can still return a critical failure for this function if
+it can't get the device operational after reset. If the platform
+previously tried a soft reset, it migh now try a hard reset (power
+cycle) and then call slot_reset() again. It the device still can't
+be recovered, there is nothing more that can be done; the platform
+will typically report a "permanent failure" in such a case. The
+device will be considered "dead" in this case.
+
+ Result codes:
+ - PCIERR_RESULT_DISCONNECT
+ Same as above.
+
+>>> The current ppc64 implementation does not try a power-cycle reset
+>>> if the driver returned PCIERR_RESULT_DISCONNECT. However, it should.
+
+ 5) resume()
+
+ This is called if all drivers on the segment have returned
+PCIERR_RESULT_RECOVERED from one of the 3 prevous callbacks.
+That basically tells the driver to restart activity, tht everything
+is back and running. No result code is taken into account here. If
+a new error happens, it will restart a new error handling process.
+
+That's it. I think this covers all the possibilities. The way those
+callbacks are called is platform policy. A platform with no slot reset
+capability for example may want to just "ignore" drivers that can't
+recover (disconnect them) and try to let other cards on the same segment
+recover. Keep in mind that in most real life cases, though, there will
+be only one driver per segment.
+
+Now, there is a note about interrupts. If you get an interrupt and your
+device is dead or has been isolated, there is a problem :)
+
+After much thinking, I decided to leave that to the platform. That is,
+the recovery API only precies that:
+
+ - There is no guarantee that interrupt delivery can proceed from any
+device on the segment starting from the error detection and until the
+restart callback is sent, at which point interrupts are expected to be
+fully operational.
+
+ - There is no guarantee that interrupt delivery is stopped, that is, ad
+river that gets an interrupts after detecting an error, or that detects
+and error within the interrupt handler such that it prevents proper
+ack'ing of the interrupt (and thus removal of the source) should just
+return IRQ_NOTHANDLED. It's up to the platform to deal with taht
+condition, typically by masking the irq source during the duration of
+the error handling. It is expected that the platform "knows" which
+interrupts are routed to error-management capable slots and can deal
+with temporarily disabling that irq number during error processing (this
+isn't terribly complex). That means some IRQ latency for other devices
+sharing the interrupt, but there is simply no other way. High end
+platforms aren't supposed to share interrupts between many devices
+anyway :)

+Introduction
+-------------------------
+The aacraid driver adds support for Adaptec (http://www.adaptec.com)
+RAID controllers. This is a major rewrite from the original
+Adaptec supplied driver. It has signficantly cleaned up both the code
+and the running binary size (the module is less than half the size of
+the original).

+spi_butterfly - parport-to-butterfly adapter driver
+===================================================
+
+This is a hardware and software project that includes building and using
+a parallel port adapter cable, together with an "AVR Butterfly" to run
+firmware for user interfacing and/or sensors. A Butterfly is a $US20
+battery powered card with an AVR microcontroller and lots of goodies:
+sensors, LCD, flash, toggle stick, and more. You can use AVR-GCC to
+develop firmware for this, and flash it using this adapter cable.
+
+You can make this adapter from an old printer cable and solder things
+directly to the Butterfly. Or (if you have the parts and skills) you
+can come up with something fancier, providing ciruit protection to the
+Butterfly and the printer port, or with a better power supply than two
+signal pins from the printer port.
+
+
+The first cable connections will hook Linux up to one SPI bus, with the
+AVR and a DataFlash chip; and to the AVR reset line. This is all you
+need to reflash the firmware, and the pins are the standard Atmel "ISP"
+connector pins (used also on non-Butterfly AVR boards).
+
+ Signal Butterfly Parport (DB-25)
+ ------ --------- ---------------
+ SCK = J403.PB1/SCK = pin 2/D0
+ RESET = J403.nRST = pin 3/D1

+ MOSI = J403.PB2/MOSI = pin 9/D7
+ MISO = J403.PB3/MISO = pin 11/S7,nBUSY
+ GND = J403.GND = pin 23/GND
+
+Then to let Linux master that bus to talk to the DataFlash chip, you must
+(a) flash new firmware that disables SPI (set PRR.2, and disable pullups
+by clearing PORTB.[0-3]); (b) configure the mtd_dataflash driver; and
+(c) cable in the chipselect.

+ SELECT = J400.PB0/nSS = pin 17/C3,nSELECT
+ GND = J400.GND = pin 24/GND
+
+The "USI" controller, using J405, can be used for a second SPI bus. That
+would let you talk to the AVR over SPI, running firmware that makes it act
+as an SPI slave, while letting either Linux or the AVR use the DataFlash.
+There are plenty of spare parport pins to wire this one up, such as:

+Overview of Linux kernel SPI support
+====================================
+
+02-Dec-2005
+
+What is SPI?
+------------
+The "Serial Peripheral Interface" (SPI) is a synchronous four wire serial
+link used to connect microcontrollers to sensors, memory, and peripherals.
+
+The three signal wires hold a clock (SCLK, often on the order of 10 MHz),
+and parallel data lines with "Master Out, Slave In" (MOSI) or "Master In,
+Slave Out" (MISO) signals. (Other names are also used.) There are four
+clocking modes through which data is exchanged; mode-0 and mode-3 are most
+commonly used. Each clock cycle shifts data out and data in; the clock
+doesn't cycle except when there is data to shift.
+
+SPI masters may use a "chip select" line to activate a given SPI slave
+device, so those three signal wires may be connected to several chips
+in parallel. All SPI slaves support chipselects. Some devices have
+other signals, often including an interrupt to the master.
+
+Unlike serial busses like USB or SMBUS, even low level protocols for
+SPI slave functions are usually not interoperable between vendors
+(except for cases like SPI memory chips).
+
+ - SPI may be used for request/response style device protocols, as with
+ touchscreen sensors and memory chips.
+
+ - It may also be used to stream data in either direction (half duplex),
+ or both of them at the same time (full duplex).
+
+ - Some devices may use eight bit words. Others may different word
+ lengths, such as streams of 12-bit or 20-bit digital samples.
+
+In the same way, SPI slaves will only rarely support any kind of automatic
+discovery/enumeration protocol. The tree of slave devices accessible from
+a given SPI master will normally be set up manually, with configuration
+tables.
+
+SPI is only one of the names used by such four-wire protocols, and
+most controllers have no problem handling "MicroWire" (think of it as
+half-duplex SPI, for request/response protocols), SSP ("Synchronous
+Serial Protocol"), PSP ("Programmable Serial Protocol"), and other
+related protocols.
+
+Microcontrollers often support both master and slave sides of the SPI
+protocol. This document (and Linux) currently only supports the master
+side of SPI interactions.
+
+
+Who uses it? On what kinds of systems?
+---------------------------------------
+Linux developers using SPI are probably writing device drivers for embedded
+systems boards. SPI is used to control external chips, and it is also a
+protocol supported by every MMC or SD memory card. (The older "DataFlash"
+cards, predating MMC cards but using the same connectors and card shape,
+support only SPI.) Some PC hardware uses SPI flash for BIOS code.
+
+SPI slave chips range from digital/analog converters used for analog
+sensors and codecs, to memory, to peripherals like USB controllers
+or Ethernet adapters; and more.
+
+Most systems using SPI will integrate a few devices on a mainboard.
+Some provide SPI links on expansion connectors; in cases where no
+dedicated SPI controller exists, GPIO pins can be used to create a
+low speed "bitbanging" adapter. Very few systems will "hotplug" an SPI
+controller; the reasons to use SPI focus on low cost and simple operation,
+and if dynamic reconfiguration is important, USB will often be a more
+appropriate low-pincount peripheral bus.
+
+Many microcontrollers that can run Linux integrate one or more I/O
+interfaces with SPI modes. Given SPI support, they could use MMC or SD
+cards without needing a special purpose MMC/SD/SDIO controller.
+
+
+How do these driver programming interfaces work?
+------------------------------------------------
+The <linux/spi/spi.h> header file includes kerneldoc, as does the
+main source code, and you should certainly read that. This is just
+an overview, so you get the big picture before the details.
+
+SPI requests always go into I/O queues. Requests for a given SPI device
+are always executed in FIFO order, and complete asynchronously through
+completion callbacks. There are also some simple synchronous wrappers
+for those calls, including ones for common transaction types like writing
+a command and then reading its response.
+
+There are two types of SPI driver, here called:
+
+ Controller drivers ... these are often built in to System-On-Chip
+ processors, and often support both Master and Slave roles.
+ These drivers touch hardware registers and may use DMA.
+ Or they can be PIO bitbangers, needing just GPIO pins.
+
+ Protocol drivers ... these pass messages through the controller
+ driver to communicate with a Slave or Master device on the
+ other side of an SPI link.
+
+So for example one protocol driver might talk to the MTD layer to export
+data to filesystems stored on SPI flash like DataFlash; and others might
+control audio interfaces, present touchscreen sensors as input interfaces,
+or monitor temperature and voltage levels during industrial processing.
+And those might all be sharing the same controller driver.
+
+A "struct spi_device" encapsulates the master-side interface between
+those two types of driver. At this writing, Linux has no slave side
+programming interface.
+
+There is a minimal core of SPI programming interfaces, focussing on
+using driver model to connect controller and protocol drivers using
+device tables provided by board specific initialization code. SPI
+shows up in sysfs in several locations:
+
+ /sys/devices/.../CTLR/spiB.C ... spi_device for on bus "B",
+ chipselect C, accessed through CTLR.
+
+ /sys/devices/.../CTLR/spiB.C/modalias ... identifies the driver
+ that should be used with this device (for hotplug/coldplug)
+
+ /sys/bus/spi/devices/spiB.C ... symlink to the physical
+ spiB-C device
+
+ /sys/bus/spi/drivers/D ... driver for one or more spi*.* devices
+
+ /sys/class/spi_master/spiB ... class device for the controller
+ managing bus "B". All the spiB.* devices share the same
+ physical SPI bus segment, with SCLK, MOSI, and MISO.
+
+
+How does board-specific init code declare SPI devices?
+------------------------------------------------------
+Linux needs several kinds of information to properly configure SPI devices.
+That information is normally provided by board-specific code, even for
+chips that do support some of automated discovery/enumeration.
+
+DECLARE CONTROLLERS
+
+The first kind of information is a list of what SPI controllers exist.
+For System-on-Chip (SOC) based boards, these will usually be platform
+devices, and the controller may need some platform_data in order to
+operate properly. The "struct platform_device" will include resources
+like the physical address of the controller's first register and its IRQ.
+
+Platforms will often abstract the "register SPI controller" operation,
+maybe coupling it with code to initialize pin configurations, so that
+the arch/.../mach-*/board-*.c files for several boards can all share the
+same basic controller setup code. This is because most SOCs have several
+SPI-capable controllers, and only the ones actually usable on a given
+board should normally be set up and registered.
+
+So for example arch/.../mach-*/board-*.c files might have code like:
+
+ #include <asm/arch/spi.h> /* for mysoc_spi_data */
+
+ /* if your mach-* infrastructure doesn't support kernels that can
+ * run on multiple boards, pdata wouldn't benefit from "__init".
+ */
+ static struct mysoc_spi_data __init pdata = { ... };
+
+ static __init board_init(void)
+ {
+ ...
+ /* this board only uses SPI controller #2 */
+ mysoc_register_spi(2, &pdata);
+ ...
+ }
+
+And SOC-specific utility code might look something like:
+
+ #include <asm/arch/spi.h>
+
+ static struct platform_device spi2 = { ... };
+
+ void mysoc_register_spi(unsigned n, struct mysoc_spi_data *pdata)
+ {
+ struct mysoc_spi_data *pdata2;
+
+ pdata2 = kmalloc(sizeof *pdata2, GFP_KERNEL);
+ *pdata2 = pdata;
+ ...
+ if (n == 2) {
+ spi2->dev.platform_data = pdata2;
+ register_platform_device(&spi2);
+
+ /* also: set up pin modes so the spi2 signals are
+ * visible on the relevant pins ... bootloaders on
+ * production boards may already have done this, but
+ * developer boards will often need Linux to do it.
+ */
+ }
+ ...
+ }
+
+Notice how the platform_data for boards may be different, even if the
+same SOC controller is used. For example, on one board SPI might use
+an external clock, where another derives the SPI clock from current
+settings of some master clock.
+
+
+DECLARE SLAVE DEVICES
+
+The second kind of information is a list of what SPI slave devices exist
+on the target board, often with some board-specific data needed for the
+driver to work correctly.
+
+Normally your arch/.../mach-*/board-*.c files would provide a small table
+listing the SPI devices on each board. (This would typically be only a
+small handful.) That might look like:
+
+ static struct ads7846_platform_data ads_info = {
+ .vref_delay_usecs = 100,
+ .x_plate_ohms = 580,
+ .y_plate_ohms = 410,
+ };
+
+ static struct spi_board_info spi_board_info[] __initdata = {
+ {
+ .modalias = "ads7846",
+ .platform_data = &ads_info,
+ .mode = SPI_MODE_0,
+ .irq = GPIO_IRQ(31),
+ .max_speed_hz = 120000 /* max sample rate at 3V */ * 16,
+ .bus_num = 1,
+ .chip_select = 0,
+ },
+ };
+
+Again, notice how board-specific information is provided; each chip may need
+several types. This example shows generic constraints like the fastest SPI
+clock to allow (a function of board voltage in this case) or how an IRQ pin
+is wired, plus chip-specific constraints like an important delay that's
+changed by the capacitance at one pin.
+
+(There's also "controller_data", information that may be useful to the
+controller driver. An example would be peripheral-specific DMA tuning
+data or chipselect callbacks. This is stored in spi_device later.)
+
+The board_info should provide enough information to let the system work
+without the chip's driver being loaded. The most troublesome aspect of
+that is likely the SPI_CS_HIGH bit in the spi_device.mode field, since
+sharing a bus with a device that interprets chipselect "backwards" is
+not possible.
+
+Then your board initialization code would register that table with the SPI
+infrastructure, so that it's available later when the SPI master controller
+driver is registered:
+
+ spi_register_board_info(spi_board_info, ARRAY_SIZE(spi_board_info));
+
+Like with other static board-specific setup, you won't unregister those.
+
+The widely used "card" style computers bundle memory, cpu, and little else
+onto a card that's maybe just thirty square centimeters. On such systems,
+your arch/.../mach-.../board-*.c file would primarily provide information
+about the devices on the mainboard into which such a card is plugged. That
+certainly includes SPI devices hooked up through the card connectors!
+
+
+NON-STATIC CONFIGURATIONS
+
+Developer boards often play by different rules than product boards, and one
+example is the potential need to hotplug SPI devices and/or controllers.
+
+For those cases you might need to use use spi_busnum_to_master() to look
+up the spi bus master, and will likely need spi_new_device() to provide the
+board info based on the board that was hotplugged. Of course, you'd later
+call at least spi_unregister_device() when that board is removed.
+
+When Linux includes support for MMC/SD/SDIO/DataFlash cards through SPI, those
+configurations will also be dynamic. Fortunately, those devices all support
+basic device identification probes, so that support should hotplug normally.
+
+
+How do I write an "SPI Protocol Driver"?
+----------------------------------------
+All SPI drivers are currently kernel drivers. A userspace driver API
+would just be another kernel driver, probably offering some lowlevel
+access through aio_read(), aio_write(), and ioctl() calls and using the
+standard userspace sysfs mechanisms to bind to a given SPI device.
+
+SPI protocol drivers somewhat resemble platform device drivers:
+
+ static struct spi_driver CHIP_driver = {
+ .driver = {
+ .name = "CHIP",
+ .bus = &spi_bus_type,
+ .owner = THIS_MODULE,
+ },
+
+ .probe = CHIP_probe,
+ .remove = __devexit_p(CHIP_remove),
+ .suspend = CHIP_suspend,
+ .resume = CHIP_resume,
+ };
+
+The driver core will autmatically attempt to bind this driver to any SPI
+device whose board_info gave a modalias of "CHIP". Your probe() code
+might look like this unless you're creating a class_device:
+
+ static int __devinit CHIP_probe(struct spi_device *spi)
+ {
+ struct CHIP *chip;
+ struct CHIP_platform_data *pdata;
+
+ /* assuming the driver requires board-specific data: */
+ pdata = &spi->dev.platform_data;
+ if (!pdata)
+ return -ENODEV;
+
+ /* get memory for driver's per-chip state */
+ chip = kzalloc(sizeof *chip, GFP_KERNEL);
+ if (!chip)
+ return -ENOMEM;
+ dev_set_drvdata(&spi->dev, chip);
+
+ ... etc
+ return 0;
+ }
+
+As soon as it enters probe(), the driver may issue I/O requests to
+the SPI device using "struct spi_message". When remove() returns,
+the driver guarantees that it won't submit any more such messages.
+
+ - An spi_message is a sequence of of protocol operations, executed
+ as one atomic sequence. SPI driver controls include:
+
+ + when bidirectional reads and writes start ... by how its
+ sequence of spi_transfer requests is arranged;
+
+ + optionally defining short delays after transfers ... using
+ the spi_transfer.delay_usecs setting;
+
+ + whether the chipselect becomes inactive after a transfer and
+ any delay ... by using the spi_transfer.cs_change flag;
+
+ + hinting whether the next message is likely to go to this same
+ device ... using the spi_transfer.cs_change flag on the last
+ transfer in that atomic group, and potentially saving costs
+ for chip deselect and select operations.
+
+ - Follow standard kernel rules, and provide DMA-safe buffers in
+ your messages. That way controller drivers using DMA aren't forced
+ to make extra copies unless the hardware requires it (e.g. working
+ around hardware errata that force the use of bounce buffering).
+
+ If standard dma_map_single() handling of these buffers is inappropriate,
+ you can use spi_message.is_dma_mapped to tell the controller driver
+ that you've already provided the relevant DMA addresses.
+
+ - The basic I/O primitive is spi_async(). Async requests may be
+ issued in any context (irq handler, task, etc) and completion
+ is reported using a callback provided with the message.
+ After any detected error, the chip is deselected and processing
+ of that spi_message is aborted.
+
+ - There are also synchronous wrappers like spi_sync(), and wrappers
+ like spi_read(), spi_write(), and spi_write_then_read(). These
+ may be issued only in contexts that may sleep, and they're all
+ clean (and small, and "optional") layers over spi_async().
+
+ - The spi_write_then_read() call, and convenience wrappers around
+ it, should only be used with small amounts of data where the
+ cost of an extra copy may be ignored. It's designed to support
+ common RPC-style requests, such as writing an eight bit command
+ and reading a sixteen bit response -- spi_w8r16() being one its
+ wrappers, doing exactly that.
+
+Some drivers may need to modify spi_device characteristics like the
+transfer mode, wordsize, or clock rate. This is done with spi_setup(),
+which would normally be called from probe() before the first I/O is
+done to the device.
+
+While "spi_device" would be the bottom boundary of the driver, the
+upper boundaries might include sysfs (especially for sensor readings),
+the input layer, ALSA, networking, MTD, the character device framework,
+or other Linux subsystems.
+
+Note that there are two types of memory your driver must manage as part
+of interacting with SPI devices.
+
+ - I/O buffers use the usual Linux rules, and must be DMA-safe.
+ You'd normally allocate them from the heap or free page pool.
+ Don't use the stack, or anything that's declared "static".
+
+ - The spi_message and spi_transfer metadata used to glue those
+ I/O buffers into a group of protocol transactions. These can
+ be allocated anywhere it's convenient, including as part of
+ other allocate-once driver data structures. Zero-init these.
+
+If you like, spi_message_alloc() and spi_message_free() convenience
+routines are available to allocate and zero-initialize an spi_message
+with several transfers.
+
+
+How do I write an "SPI Master Controller Driver"?
+-------------------------------------------------
+An SPI controller will probably be registered on the platform_bus; write
+a driver to bind to the device, whichever bus is involved.
+
+The main task of this type of driver is to provide an "spi_master".
+Use spi_alloc_master() to allocate the master, and class_get_devdata()
+to get the driver-private data allocated for that device.
+
+ struct spi_master *master;
+ struct CONTROLLER *c;
+
+ master = spi_alloc_master(dev, sizeof *c);
+ if (!master)
+ return -ENODEV;
+
+ c = class_get_devdata(&master->cdev);
+
+The driver will initialize the fields of that spi_master, including the
+bus number (maybe the same as the platform device ID) and three methods
+used to interact with the SPI core and SPI protocol drivers. It will
+also initialize its own internal state.
+
+ master->setup(struct spi_device *spi)
+ This sets up the device clock rate, SPI mode, and word sizes.
+ Drivers may change the defaults provided by board_info, and then
+ call spi_setup(spi) to invoke this routine. It may sleep.
+
+ master->transfer(struct spi_device *spi, struct spi_message *message)
+ This must not sleep. Its responsibility is arrange that the
+ transfer happens and its complete() callback is issued; the two
+ will normally happen later, after other transfers complete.
+
+ master->cleanup(struct spi_device *spi)
+ Your controller driver may use spi_device.controller_state to hold
+ state it dynamically associates with that device. If you do that,
+ be sure to provide the cleanup() method to free that state.
+
+The bulk of the driver will be managing the I/O queue fed by transfer().
+
+That queue could be purely conceptual. For example, a driver used only
+for low-frequency sensor acess might be fine using synchronous PIO.
+
+But the queue will probably be very real, using message->queue, PIO,
+often DMA (especially if the root filesystem is in SPI flash), and
+execution contexts like IRQ handlers, tasklets, or workqueues (such
+as keventd). Your driver can be as fancy, or as simple, as you need.

+Firmware support for CPU hotplug under Linux/x86-64
+---------------------------------------------------
+
+Linux/x86-64 supports CPU hotplug now. For various reasons Linux wants to
+know in advance boot time the maximum number of CPUs that could be plugged
+into the system. ACPI 3.0 currently has no official way to supply
+this information from the firmware to the operating system.
+
+In ACPI each CPU needs an LAPIC object in the MADT table (5.2.11.5 in the
+ACPI 3.0 specification). ACPI already has the concept of disabled LAPIC
+objects by setting the Enabled bit in the LAPIC object to zero.
+
+For CPU hotplug Linux/x86-64 expects now that any possible future hotpluggable
+CPU is already available in the MADT. If the CPU is not available yet
+it should have its LAPIC Enabled bit set to 0. Linux will use the number
+of disabled LAPICs to compute the maximum number of future CPUs.
+
+In the worst case the user can overwrite this choice using a command line
+option (additional_cpus=...), but it is recommended to supply the correct
+number (or a reasonable approximation of it, with erring towards more not less)
+in the MADT to avoid manual configuration.

+ Linux is a clone of the operating system Unix, written from scratch by
+ Linus Torvalds with assistance from a loosely-knit team of hackers across
+ the Net. It aims towards POSIX and Single UNIX Specification compliance.
- It has all the features you would expect in a modern fully-fledged
- Unix, including true multitasking, virtual memory, shared libraries,
- demand loading, shared copy-on-write executables, proper memory
- management and TCP/IP networking.
+ It has all the features you would expect in a modern fully-fledged Unix,
+ including true multitasking, virtual memory, shared libraries, demand
+ loading, shared copy-on-write executables, proper memory management,
+ and multistack networking including IPv4 and IPv6.
It is distributed under the GNU General Public License - see the
accompanying COPYING file for more details.
ON WHAT HARDWARE DOES IT RUN?
- Linux was first developed for 386/486-based PCs. These days it also
- runs on ARMs, DEC Alphas, SUN Sparcs, M68000 machines (like Atari and
- Amiga), MIPS and PowerPC, and others.
+ Although originally developed first for 32-bit x86-based PCs (386 or higher),
+ today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
+ UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH,
+ IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
+ and Renesas M32R architectures.
+
+ Linux is easily portable to most general-purpose 32- or 64-bit architectures
+ as long as they have a paged memory management unit (PMMU) and a port of the
+ GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
+ also been ported to a number of architectures without a PMMU, although
+ functionality is then obviously somewhat limited.

+ * The legacy ABI and the new ARM EABI have different rules making some
+ * syscalls incompatible especially with structure arguments.
+ * Most notably, Eabi says 64-bit members should be 64-bit aligned instead of
+ * simply word aligned. EABI also pads structures to the size of the largest
+ * member it contains instead of the invariant 32-bit.
+ *
+ * The following syscalls are affected:
+ *
+ * sys_stat64:
+ * sys_lstat64:
+ * sys_fstat64:
+ *
+ * struct stat64 has different sizes and some members are shifted
+ * Compatibility wrappers are needed for them and provided below.
+ *
+ * sys_fcntl64:
+ *
+ * struct flock64 has different sizes and some members are shifted
+ * A compatibility wrapper is needed and provided below.
+ *
+ * sys_statfs64:
+ * sys_fstatfs64:
+ *
+ * struct statfs64 has extra padding with EABI growing its size from
+ * 84 to 88. This struct is now __attribute__((packed,aligned(4)))
+ * with a small assembly wrapper to force the sz argument to 84 if it is 88
+ * to avoid copying the extra padding over user space unexpecting it.
+ *
+ * sys_newuname:
+ *
+ * struct new_utsname has no padding with EABI. No problem there.
+ *
+ * sys_epoll_ctl:
+ * sys_epoll_wait:
+ *
+ * struct epoll_event has its second member shifted also affecting the
+ * structure size. Compatibility wrappers are needed and provided below.
+ *
+ * sys_ipc:
+ * sys_semop:
+ * sys_semtimedop:
+ *
+ * struct sembuf loses its padding with EABI. Since arrays of them are
+ * used they have to be copyed to remove the padding. Compatibility wrappers
+ * provided below.

- Minor cleanups.
- v1.30
- 19990208 Zoltán Böszörményi <zboszor@mail.externet.hu>

- Turned <set_mtrr_up> and <get_mtrr> into function pointers.
- v1.31
- 19990212 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Major rewrite of cyrix_arr_init(): do not touch ARRs,
- leave them as the BIOS have set them up.
- Enable usage of all 8 ARRs.
- Avoid multiplications by 3 everywhere and other
- code clean ups/speed ups.
- 19990213 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Set up other Cyrix processors identical to the boot cpu.
- Since Cyrix don't support Intel APIC, this is l'art pour l'art.
- Weigh ARRs by size:
- If size <= 32M is given, set up ARR# we were given.
- If size > 32M is given, set up ARR7 only if it is free,
- fail otherwise.
- 19990214 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Also check for size >= 256K if we are to set up ARR7,
- mtrr_add() returns the value it gets from set_mtrr()
- 19990218 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Remove Cyrix "coma bug" workaround from here.
- Moved to linux/arch/i386/kernel/setup.c and
- linux/include/asm-i386/bugs.h
- 19990228 Richard Gooch <rgooch@atnf.csiro.au>
- Added MTRRIOC_KILL_ENTRY ioctl(2)
- Trap for counter underflow in <mtrr_file_del>.
- Trap for 4 MiB aligned regions for PPro, stepping <= 7.
- 19990301 Richard Gooch <rgooch@atnf.csiro.au>
- Created <get_free_region> hook.
- 19990305 Richard Gooch <rgooch@atnf.csiro.au>
- Temporarily disable AMD support now MTRR capability flag is set.
- v1.32
- 19990308 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Adjust my changes (19990212-19990218) to Richard Gooch's
- latest changes. (19990228-19990305)
- v1.33
- 19990309 Richard Gooch <rgooch@atnf.csiro.au>
- Fixed typo in <printk> message.
- 19990310 Richard Gooch <rgooch@atnf.csiro.au>
- Support K6-II/III based on Alan Cox's <alan@redhat.com> patches.
- v1.34
- 19990511 Bart Hartgers <bart@etpmod.phys.tue.nl>
- Support Centaur C6 MCR's.
- 19990512 Richard Gooch <rgooch@atnf.csiro.au>
- Minor cleanups.
- v1.35
- 19990707 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Check whether ARR3 is protected in cyrix_get_free_region()
- and mtrr_del(). The code won't attempt to delete or change it
- from now on if the BIOS protected ARR3. It silently skips ARR3
- in cyrix_get_free_region() or returns with an error code from
- mtrr_del().
- 19990711 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Reset some bits in the CCRs in cyrix_arr_init() to disable SMM
- if ARR3 isn't protected. This is needed because if SMM is active
- and ARR3 isn't protected then deleting and setting ARR3 again
- may lock up the processor. With SMM entirely disabled, it does
- not happen.
- 19990812 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Rearrange switch() statements so the driver accomodates to
- the fact that the AMD Athlon handles its MTRRs the same way
- as Intel does.
- 19990814 Zoltán Böszörményi <zboszor@mail.externet.hu>
- Double check for Intel in mtrr_add()'s big switch() because
- that revision check is only valid for Intel CPUs.
- 19990819 Alan Cox <alan@redhat.com>
- Tested Zoltan's changes on a pre production Athlon - 100%
- success.
- 19991008 Manfred Spraul <manfreds@colorfullife.com>
- replaced spin_lock_reschedule() with a normal semaphore.
- v1.36
- 20000221 Richard Gooch <rgooch@atnf.csiro.au>
- Compile fix if procfs and devfs not enabled.
- Formatting changes.
- v1.37
- 20001109 H. Peter Anvin <hpa@zytor.com>
- Use the new centralized CPU feature detects.
-
- v1.38
- 20010309 Dave Jones <davej@suse.de>
- Add support for Cyrix III.
-
- v1.39
- 20010312 Dave Jones <davej@suse.de>
- Ugh, I broke AMD support.
- Reworked fix by Troels Walsted Hansen <troels@thule.no>
-
- v1.40
- 20010327 Dave Jones <davej@suse.de>
- Adapted Cyrix III support to include VIA C3.
-
- v2.0
- 20020306 Patrick Mochel <mochel@osdl.org>
- Split mtrr.c -> mtrr/*.c
- Converted to Linux Kernel Coding Style
- Fixed several minor nits in form
- Moved some SMP-only functions out, so they can be used
- for power management in the future.
- TODO: Fix user interface cruft.

- * the reserved page
- *
- * SAL reserves one page of memory per partition for XPC. Though a full page
- * in length (16384 bytes), its starting address is not page aligned, but it
- * is cacheline aligned. The reserved page consists of the following:
- *
- * reserved page header
- *
- * The first cacheline of the reserved page contains the header
- * (struct xpc_rsvd_page). Before SAL initialization has completed,
- * SAL has set up the following fields of the reserved page header:
- * SAL_signature, SAL_version, partid, and nasids_size. The other
- * fields are set up by XPC. (xpc_rsvd_page points to the local
- * partition's reserved page.)
- *
- * part_nasids mask
- * mach_nasids mask
- *
- * SAL also sets up two bitmaps (or masks), one that reflects the actual
- * nasids in this partition (part_nasids), and the other that reflects
- * the actual nasids in the entire machine (mach_nasids). We're only
- * interested in the even numbered nasids (which contain the processors
- * and/or memory), so we only need half as many bits to represent the
- * nasids. The part_nasids mask is located starting at the first cacheline
- * following the reserved page header. The mach_nasids mask follows right
- * after the part_nasids mask. The size in bytes of each mask is reflected
- * by the reserved page header field 'nasids_size'. (Local partition's
- * mask pointers are xpc_part_nasids and xpc_mach_nasids.)
- *
- * vars
- * vars part
- *
- * Immediately following the mach_nasids mask are the XPC variables
- * required by other partitions. First are those that are generic to all
- * partitions (vars), followed on the next available cacheline by those
- * which are partition specific (vars part). These are setup by XPC.
- * (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
- *
- * Note: Until vars_pa is set, the partition XPC code has not been initialized.

+ * (2) Allocate resources for all enabled devices. If there is

- * This file contains some low-level i2c access routines that
- * need to be used by various bits of the PowerMac platform code
- * at times where the real asynchronous & interrupt driven driver
- * cannot be used. The API borrows some semantics from the darwin
- * driver in order to ease the implementation of the platform
- * properties parser
+ * The linux i2c layer isn't completely suitable for our needs for various
+ * reasons ranging from too late initialisation to semantics not perfectly
+ * matching some requirements of the apple platform functions etc...
+ *
+ * This file thus provides a simple low level unified i2c interface for
+ * powermac that covers the various types of i2c busses used in Apple machines.
+ * For now, keywest, PMU and SMU, though we could add Cuda, or other bit
+ * banging busses found on older chipstes in earlier machines if we ever need
+ * one of them.
+ *
+ * The drivers in this file are synchronous/blocking. In addition, the
+ * keywest one is fairly slow due to the use of msleep instead of interrupts
+ * as the interrupt is currently used by i2c-keywest. In the long run, we
+ * might want to get rid of those high-level interfaces to linux i2c layer
+ * either completely (converting all drivers) or replacing them all with a
+ * single stub driver on top of this one. Once done, the interrupt will be
+ * available for our use.

+ kexec is a system call that implements the ability to shutdown your
+ current kernel, and to start another kernel. It is like a reboot
+ but it is indepedent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. It may help to enable device hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.

+ This is the driver for the built-in watchdog timer on the EPX-C3
+ Single-board computer made by Winsystems, Inc.
+
+ *Note*: This hardware watchdog is not probeable and thus there
+ is no way to know if writing to its IO address will corrupt
+ your system or have any real effect. The only way to be sure
+ that this driver does what you want is to make sure you
+ are runnning it on an EPX-C3 from Winsystems with the watchdog
+ timer at IO address 0x1ee and 0x1ef. It will write to both those
+ IO ports. Basically, the assumption is made that if you compile
+ this driver into your kernel and/or load it as a module, that you
+ know what you are doing and that you are in fact running on an
+ EPX-C3 board!
+
+ To compile this driver as a module, choose M here: the
+ module will be called sbc_epx_c3.

+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!). In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices: The individual chip on a memory stick. These devices
+ * commonly output 4 and 8 bits each. Grouping several
+ * of these in parallel provides 64 bits which is common
+ * for a memory stick.
+ *
+ * Memory Stick: A printed circuit board that agregates multiple
+ * memory devices in parallel. This is the atomic
+ * memory component that is purchaseable by Joe consumer
+ * and loaded into a memory socket.
+ *
+ * Socket: A physical connector on the motherboard that accepts
+ * a single memory stick.
+ *
+ * Channel: Set of memory devices on a memory stick that must be
+ * grouped in parallel with one or more additional
+ * channels from other memory sticks. This parallel
+ * grouping of the output from multiple channels are
+ * necessary for the smallest granularity of memory access.
+ * Some memory controllers are capable of single channel -
+ * which means that memory sticks can be loaded
+ * individually. Other memory controllers are only
+ * capable of dual channel - which means that memory
+ * sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row: All of the memory devices that are selected together.
+ * for a single, minimum grain of memory access.
+ * This selects all of the parallel memory devices across
+ * all of the parallel channels. Common chip-select rows
+ * for single channel are 64 bits, for dual channel 128
+ * bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memmory.
+ * Motherboards commonly drive two chip-select pins to
+ * a memory stick. A single-ranked stick, will occupy
+ * only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently.
+ *
+ * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
+ * A double-sided stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently. "Double-sided"
+ * is irrespective of the memory devices being mounted
+ * on both sides of the memory stick.
+ *
+ * Socket set: All of the memory sticks that are required for for
+ * a single memory access or all of the memory sticks
+ * spanned by a chip-select row. A single socket set
+ * has two chip-select rows and if double-sided sticks
+ * are used these will occupy those chip-select rows.
+ *
+ * Bank: This term is avoided because it is unclear when
+ * needing to distinguish between chip-select rows and
+ * socket sets.
+ *
+ * Controller pages:
+ *
+ * Physical pages:
+ *
+ * Virtual pages:
+ *
+ *
+ * STRUCTURE ORGANIZATION AND CHOICES

+ * PS - I enjoyed writing all that about as much as you enjoyed reading it.

- Changes:
-
- 2001/12/13 BenH New implementation
- 2001/12/15 BenH Add support for "byte" and "quick"
- transfers. Add i2c_xfer routine.
- 2003/09/21 BenH Rework state machine with Paulus help
- 2004/01/21 BenH Merge in Greg KH changes, polled mode is back
- 2004/02/05 BenH Merge 64 bits fixes from the g5 ppc64 tree
-
- My understanding of the various modes supported by keywest are:
-
- - Dumb mode : not implemented, probably direct tweaking of lines
- - Standard mode : simple i2c transaction of type
- S Addr R/W A Data A Data ... T
- - Standard sub mode : combined 8 bit subaddr write with data read
- S Addr R/W A SubAddr A Data A Data ... T
- - Combined mode : Subaddress and Data sequences appended with no stop
- S Addr R/W A SubAddr S Addr R/W A Data A Data ... T
-
- Currently, this driver uses only Standard mode for i2c xfer, and
- smbus byte & quick transfers ; and uses StandardSub mode for
- other smbus transfers instead of combined as we need that for the
- sound driver to be happy

-/* OVERVIEW
- * --------
- *
- * The AMDTP driver is designed to expose the IEEE1394 bus as a
- * regular OSS soundcard, i.e. you can link /dev/dsp to /dev/amdtp and
- * then your favourite MP3 player, game or whatever sound program will
- * output to an IEEE1394 isochronous channel. The signal destination
- * could be a set of IEEE1394 loudspeakers (if and when such things
- * become available) or an amplifier with IEEE1394 input (like the
- * Sony STR-LSA1). The driver only handles the actual streaming, some
- * connection management is also required for this to actually work.
- * That is outside the scope of this driver, and furthermore it is not
- * really standardized yet.
- *
- * The Audio and Music Data Tranmission Protocol is available at
- *
- * http://www.1394ta.org/Download/Technology/Specifications/2001/AM20Final-jf2.pdf
- *
- *
- * TODO
- * ----
- *
- * - We should be able to change input sample format between LE/BE, as
- * we already shift the bytes around when we construct the iso
- * packets.
- *
- * - Fix DMA stop after bus reset!
- *
- * - Clean up iso context handling in ohci1394.
- *
- *
- * MAYBE TODO
- * ----------
- *
- * - Receive data for local playback or recording. Playback requires
- * soft syncing with the sound card.
- *
- * - Signal processing, i.e. receive packets, do some processing, and
- * transmit them again using the same packet structure and timestamps
- * offset by processing time.
- *
- * - Maybe make an ALSA interface, that is, create a file_ops
- * implementation that recognizes ALSA ioctls and uses defaults for
- * things that can't be controlled through ALSA (iso channel).
- *
- * Changes:
- *
- * - Audit copy_from_user in amdtp_write.
- * Daniele Bellucci <bellucda@tiscali.it>

-/* The userspace interface for the Audio & Music Data Transmission
- * Protocol driver is really simple. First, open /dev/amdtp, use the
- * ioctl to configure format, rate, dimension and either plug or
- * channel, then start writing samples.
- *
- * The formats supported by the driver are listed below.
- * AMDTP_FORMAT_RAW corresponds to the AM824 raw format, which can
- * carry any number of channels, so use this if you're streaming
- * multichannel audio. The AMDTP_FORMAT_IEC958_PCM corresponds to the
- * AM824 IEC958 encapsulation without the IEC958 data bit set, using
- * AMDTP_FORMAT_IEC958_AC3 will transmit the samples with the data bit
- * set, suitable for transmitting compressed AC-3 audio.
- *
- * The rate field specifies the transmission rate; supported values
- * are 32000, 44100, 48000, 88200, 96000, 176400 and 192000.
- *
- * The dimension field specifies the dimension of the signal, that is,
- * the number of audio channels. Only AMDTP_FORMAT_RAW supports
- * settings greater than 2.
- *
- * The mode field specifies which transmission mode to use. The AMDTP
- * specifies two different transmission modes: blocking and
- * non-blocking. The blocking transmission mode always send a fixed
- * number of samples, typically 8, 16 or 32. To exactly match the
- * transmission rate, the driver alternates between sending empty and
- * non-empty packets. In non-blocking mode, the driver transmits as
- * small packets as possible. For example, for a transmission rate of
- * 44100Hz, the driver should send 5 41/80 samples in every cycle, but
- * this is not possible so instead the driver alternates between
- * sending 5 and 6 samples.
- *
- * The last thing to specify is either the isochronous channel to use
- * or the output plug to connect to. If you know what channel the
- * destination device will listen on, you can specify the channel
- * directly and use the AMDTP_IOC_CHANNEL ioctl. However, if the
- * destination device chooses the channel and uses the IEC61883-1 plug
- * mechanism, you can specify an output plug to connect to. The
- * driver will pick up the channel number from the plug once the
- * destination device locks the output plug control register. In this
- * case set the plug field and use the AMDTP_IOC_PLUG ioctl.
- *
- * Having configured the interface, the driver now accepts writes of
- * regular 16 bit signed little endian samples, with the channels
- * interleaved. For example, 4 channels would look like:
- *
- * | sample 0 | sample 1 ...
- * | ch. 0 | ch. 1 | ch. 2 | ch. 3 | ch. 0 | ...
- * | lsb | msb | lsb | msb | lsb | msb | lsb | msb | lsb | msb | ...
- *

- * programming the msp34* sound processor family
- *
- * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
- *
- * what works and what doesn't:
- *
- * AM-Mono
- * Support for Hauppauge cards added (decoding handled by tuner) added by
- * Frederic Crozat <fcrozat@mail.dotcom.fr>
- *
- * FM-Mono
- * should work. The stereo modes are backward compatible to FM-mono,
- * therefore FM-Mono should be allways available.
- *
- * FM-Stereo (B/G, used in germany)
- * should work, with autodetect
- *
- * FM-Stereo (satellite)
- * should work, no autodetect (i.e. default is mono, but you can
- * switch to stereo -- untested)
- *
- * NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
- * should work, with autodetect. Support for NICAM was added by
- * Pekka Pietikainen <pp@netppl.fi>
- *
- *
- * TODO:
- * - better SAT support

/* Change Log
- * 6.0.58 4/20/05
- * o Accepted ethtool cleanup patch from Stephen Hemminger
- * 6.0.44+ 2/15/05
- * o applied Anton's patch to resolve tx hang in hardware
- * o Applied Andrew Mortons patch - e1000 stops working after resume
+ * 6.3.9 12/16/2005
+ * o incorporate fix for recycled skbs from IBM LTC
+ * 6.3.7 11/18/2005
+ * o Honor eeprom setting for enabling/disabling Wake On Lan
+ * 6.3.5 11/17/2005
+ * o Fix memory leak in rx ring handling for PCI Express adapters
+ * 6.3.4 11/8/05
+ * o Patch from Jesper Juhl to remove redundant NULL checks for kfree
+ * 6.3.2 9/20/05
+ * o Render logic that sets/resets DRV_LOAD as inline functions to
+ * avoid code replication. If f/w is AMT then set DRV_LOAD only when
+ * network interface is open.
+ * o Handle DRV_LOAD set/reset in cases where AMT uses VLANs.
+ * o Adjust PBA partioning for Jumbo frames using MTU size and not
+ * rx_buffer_len
+ * 6.3.1 9/19/05
+ * o Use adapter->tx_timeout_factor in Tx Hung Detect logic
+ (e1000_clean_tx_irq)
+ * o Support for 8086:10B5 device (Quad Port)
+ * 6.2.14 9/15/05
+ * o In AMT enabled configurations, set/reset DRV_LOAD bit on interface
+ * open/close
+ * 6.2.13 9/14/05
+ * o Invoke e1000_check_mng_mode only for 8257x controllers since it
+ * accesses the FWSM that is not supported in other controllers
+ * 6.2.12 9/9/05
+ * o Add support for device id E1000_DEV_ID_82546GB_QUAD_COPPER
+ * o set RCTL:SECRC only for controllers newer than 82543.
+ * o When the n/w interface comes down reset DRV_LOAD bit to notify f/w.
+ * This code was moved from e1000_remove to e1000_close
+ * 6.2.10 9/6/05
+ * o Fix error in updating RDT in el1000_alloc_rx_buffers[_ps] -- one off.
+ * o Enable fc by default on 82573 controllers (do not read eeprom)
+ * o Fix rx_errors statistic not to include missed_packet_count
+ * o Fix rx_dropped statistic not to include missed_packet_count
+ (Padraig Brady)
+ * 6.2.9 8/30/05
+ * o Remove call to update statistics from the controller ib e1000_get_stats
+ * 6.2.8 8/30/05
+ * o Improved algorithm for rx buffer allocation/rdt update
+ * o Flow control watermarks relative to rx PBA size
+ * o Simplified 'Tx Hung' detect logic
+ * 6.2.7 8/17/05
+ * o Report rx buffer allocation failures and tx timeout counts in stats
+ * 6.2.6 8/16/05
+ * o Implement workaround for controller erratum -- linear non-tso packet
+ * following a TSO gets written back prematurely
+ * 6.2.5 8/15/05
+ * o Set netdev->tx_queue_len based on link speed/duplex settings.
+ * o Fix net_stats.rx_fifo_errors <p@draigBrady.com>
+ * o Do not power off PHY if SoL/IDER session is active
+ * 6.2.4 8/10/05
+ * o Fix loopback test setup/cleanup for 82571/3 controllers
+ * o Fix parsing of outgoing packets (e1000_transfer_dhcp_info) to treat
+ * all packets as raw
+ * o Prevent operations that will cause the PHY to be reset if SoL/IDER
+ * sessions are active and log a message
+ * 6.2.2 7/21/05
+ * o used fixed size descriptors for all MTU sizes, reduces memory load
+ * 6.1.2 4/13/05
+ * o Fixed ethtool diagnostics
+ * o Enabled flow control to take default eeprom settings
+ * o Added stats_lock around e1000_read_phy_reg commands to avoid concurrent
+ * calls, one from mii_ioctl and other from within update_stats while
+ * processing MIIREG ioctl.

+/* drivers/net/ifb.c:
+
+ The purpose of this driver is to provide a device that allows
+ for sharing of resources:
+
+ 1) qdiscs/policies that are per device as opposed to system wide.
+ ifb allows for a device which can be redirected to thus providing
+ an impression of sharing.
+
+ 2) Allows for queueing incoming traffic for shaping instead of
+ dropping.
+
+ The original concept is based on what is known as the IMQ
+ driver initially written by Martin Devera, later rewritten
+ by Patrick McHardy and then maintained by Andre Correa.
+
+ You need the tc action mirror or redirect to feed this device
+ packets.

-AACRAID Driver for Linux (take two)
-
-Introduction
--------------------------
-The aacraid driver adds support for Adaptec (http://www.adaptec.com)
-RAID controllers. This is a major rewrite from the original
-Adaptec supplied driver. It has signficantly cleaned up both the code
-and the running binary size (the module is less than half the size of
-the original).

-People
--------------------------
-Alan Cox <alan@redhat.com>
-Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration,
- small cleanups/fixes)
-Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages)
-Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers
- added new ioctls, changed scsi interface to use new error handler,
- increased the number of fibs and outstanding commands to a container)
-
- (fixed 64bit and 64G memory model, changed confusing naming convention
- where fibs that go to the hardware are consistently called hw_fibs and
- not just fibs like the name of the driver tracking structure)
-Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas. Performance tuning, card failover and bug mitigations.
-
-Original Driver
--------------------------
-Adaptec Unix OEM Product Group
-
-Mailing List
--------------------------
-linux-scsi@vger.kernel.org (Interested parties troll here)
-Also note this is very different to Brian's original driver
-so don't expect him to support it.
-Adaptec does support this driver. Contact either tech support or Mark Salyzyn.

+config SPI
+ bool "SPI support"
+ help
+ The "Serial Peripheral Interface" is a low level synchronous
+ protocol. Chips that support SPI can have data transfer rates
+ up to several tens of Mbit/sec. Chips are addressed with a
+ controller and a chipselect. Most SPI slaves don't support
+ dynamic device discovery; some are even write-only or read-only.
+
+ SPI is widely used by microcontollers to talk with sensors,
+ eeprom and flash memory, codecs and various other controller
+ chips, analog to digital (and d-to-a) converters, and more.
+ MMC and SD cards can be accessed using SPI protocol; and for
+ DataFlash cards used in MMC sockets, SPI must always be used.
+
+ SPI is one of a family of similar protocols using a four wire
+ interface (select, clock, data in, data out) including Microwire
+ (half duplex), SSP, SSI, and PSP. This driver framework should
+ work with most such devices and controllers.
+
+config SPI_DEBUG
+ boolean "Debug support for SPI drivers"

+ sysfs, and debugfs support in SPI controller and protocol drivers.

+ help
+ With a few GPIO pins, your system can bitbang the SPI protocol.
+ Select this to get SPI support through I/O pins (GPIO, parallel
+ port, etc). Or, some systems' SPI master controller drivers use
+ this code to manage the per-word or per-transfer accesses to the
+ hardware shift registers.
+
+ This is library code, and is automatically selected by drivers that

+Version 1.40
+------------
+Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
+of readpages by eliminating one extra memcpy. Allow update of file size
+from remote server even if file is open for write as long as mount is
+directio. Recognize share mode security and send NTLM encrypted password
+on tree connect if share mode negotiated.
+
Version 1.39

+ * the reserved page
+ *
+ * SAL reserves one page of memory per partition for XPC. Though a full page
+ * in length (16384 bytes), its starting address is not page aligned, but it
+ * is cacheline aligned. The reserved page consists of the following:
+ *
+ * reserved page header
+ *
+ * The first cacheline of the reserved page contains the header
+ * (struct xpc_rsvd_page). Before SAL initialization has completed,
+ * SAL has set up the following fields of the reserved page header:
+ * SAL_signature, SAL_version, partid, and nasids_size. The other
+ * fields are set up by XPC. (xpc_rsvd_page points to the local
+ * partition's reserved page.)
+ *
+ * part_nasids mask
+ * mach_nasids mask
+ *
+ * SAL also sets up two bitmaps (or masks), one that reflects the actual
+ * nasids in this partition (part_nasids), and the other that reflects
+ * the actual nasids in the entire machine (mach_nasids). We're only
+ * interested in the even numbered nasids (which contain the processors
+ * and/or memory), so we only need half as many bits to represent the
+ * nasids. The part_nasids mask is located starting at the first cacheline
+ * following the reserved page header. The mach_nasids mask follows right
+ * after the part_nasids mask. The size in bytes of each mask is reflected
+ * by the reserved page header field 'nasids_size'. (Local partition's
+ * mask pointers are xpc_part_nasids and xpc_mach_nasids.)
+ *
+ * vars
+ * vars part
+ *
+ * Immediately following the mach_nasids mask are the XPC variables
+ * required by other partitions. First are those that are generic to all
+ * partitions (vars), followed on the next available cacheline by those
+ * which are partition specific (vars part). These are setup by XPC.
+ * (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
+ *

+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer. This is purely a performance

+ * Configuration
+ *
+ * All configuration management messaging involves sending a request message
+ * to the TIPC configuration service on a node, which sends a reply message
+ * back. (In the future multi-message replies may be supported.)
+ *
+ * Both request and reply messages consist of a transport header and payload.
+ * The transport header contains info about the desired operation;
+ * the payload consists of zero or more type/length/value (TLV) items
+ * which specify parameters or results for the operation.
+ *
+ * For many operations, the request and reply messages have a fixed number
+ * of TLVs (usually zero or one); however, some reply messages may return
+ * a variable number of TLVs. A failed request is denoted by the presence
+ * of an "error string" TLV in the reply message instead of the TLV(s) the
+ * reply should contain if the request succeeds.

+ * Frequency meter - How fast is some event occuring?
+ *
+ * These routines manage a digitally filtered, constant time based,
+ * event frequency meter. There are four routines:
+ * fmeter_init() - initialize a frequency meter.
+ * fmeter_markevent() - called each time the event happens.
+ * fmeter_getrate() - returns the recent rate of such events.
+ * fmeter_update() - internal routine used to update fmeter.
+ *
+ * A common data structure is passed to each of these routines,
+ * which is used to keep track of the state required to manage the
+ * frequency meter and its digital filter.
+ *
+ * The filter works on the number of events marked per unit time.
+ * The filter is single-pole low-pass recursive (IIR). The time unit
+ * is 1 second. Arithmetic is done using 32-bit integers scaled to
+ * simulate 3 decimal digits of precision (multiplied by 1000).
+ *
+ * With an FM_COEF of 933, and a time base of 1 second, the filter
+ * has a half-life of 10 seconds, meaning that if the events quit
+ * happening, then the rate returned from the fmeter_getrate()
+ * will be cut in half each 10 seconds, until it converges to zero.
+ *
+ * It is not worth doing a real infinitely recursive filter. If more
+ * than FM_MAXTICKS ticks have elapsed since the last filter event,
+ * just compute FM_MAXTICKS ticks worth, by which point the level
+ * will be stable.
+ *
+ * Limit the count of unprocessed events to FM_MAXCNT, so as to avoid
+ * arithmetic overflow in the fmeter_update() routine.
+ *
+ * Given the simple 32 bit integer arithmetic used, this meter works
+ * best for reporting rates between one per millisecond (msec) and
+ * one per 32 (approx) seconds. At constant rates faster than one
+ * per msec it maxes out at values just under 1,000,000. At constant
+ * rates between one per msec, and one per second it will stabilize
+ * to a value N*1000, where N is the rate of events per second.
+ * At constant rates between one per second and one per 32 seconds,
+ * it will be choppy, moving up on the seconds that have an event,
+ * and then decaying until the next event. At rates slower than
+ * about one in 32 seconds, it decays all the way back to zero between

- * we will move it to the actual list again. This way, when our
- * copy is empty, we are done. We are not all that concerned

- * aginst reentry. This way we will not stall another
- * processor. It is possible that this may delay some timers
- * that should have expired, given the new clock, but even this
- * will be minimal as we will always update to the current time,
- * even if it was set by a task that is waiting for entry to
- * this code. Timers that expire too early will be caught by

+/*
+ * SLOB Allocator: Simple List Of Blocks
+ *
+ * Matt Mackall <mpm@selenic.com> 12/30/03
+ *
+ * How SLOB works:
+ *
+ * The core of SLOB is a traditional K&R style heap allocator, with
+ * support for returning aligned objects. The granularity of this
+ * allocator is 8 bytes on x86, though it's perhaps possible to reduce
+ * this to 4 if it's deemed worth the effort. The slob heap is a
+ * singly-linked list of pages from __get_free_page, grown on demand
+ * and allocation from the heap is currently first-fit.
+ *
+ * Above this is an implementation of kmalloc/kfree. Blocks returned
+ * from kmalloc are 8-byte aligned and prepended with a 8-byte header.
+ * If kmalloc is asked for objects of PAGE_SIZE or larger, it calls
+ * __get_free_pages directly so that it can return page-aligned blocks
+ * and keeps a linked list of such pages and their orders. These
+ * objects are detected in kfree() by their page alignment.
+ *
+ * SLAB is emulated on top of SLOB by simply calling constructors and
+ * destructors for every SLAB allocation. Objects are returned with
+ * the 8-byte alignment unless the SLAB_MUST_HWCACHE_ALIGN flag is
+ * set, in which case the low-level allocator will fragment blocks to
+ * create the proper alignment. Again, objects of page-size or greater
+ * are allocated by calling __get_free_pages. As SLAB objects know
+ * their size, no separate size bookkeeping is necessary and there is
+ * essentially no allocation space overhead.

-/* Rusty: This is my (non-mathematically-inclined) understanding of
- this algorithm. The `average rate' in jiffies becomes your initial
- amount of credit `credit' and the most credit you can ever have
- `credit_cap'. The `peak rate' becomes the cost of passing the
- test, `cost'.
-
- `prev' tracks the last packet hit: you gain one credit per jiffy.
- If you get credit balance more than this, the extra credit is
- discarded. Every time the match passes, you lose `cost' credits;
- if you don't have that many, the test fails.
-
- See Alexey's formal explanation in net/sched/sch_tbf.c.
-
- To avoid underflow, we multiply by 128 (ie. you get 128 credits per
- jiffy). Hence a cost of 2^32-1, means one pass per 32768 seconds
- at 1024HZ (or one every 9 hours). A cost of 1 means 12800 passes

+ tristate '"pkttype" packet type match support'
+ depends on NETFILTER_XTABLES
+ help
+ Packet type matching allows you to match a packet by
+ its "class", eg. BROADCAST, MULTICAST, ...
+
+ Typical usage:
+ iptables -A INPUT -m pkttype --pkt-type broadcast -j LOG
+
+ To compile it as a module, choose M here. If unsure, say N.
+
+config NETFILTER_XT_MATCH_REALM
+ tristate '"realm" match support'
+ depends on NETFILTER_XTABLES
+ select NET_CLS_ROUTE
+ help
+ This option adds a `realm' match, which allows you to use the realm
+ key from the routing subsystem inside iptables.
+
+ This match pretty much resembles the CONFIG_NET_CLS_ROUTE4 option
+ in tc world.
+
+ If you want to compile it as a module, say M here and read
+ <file:Documentation/modules.txt>. If unsure, say `N'.
+
+config NETFILTER_XT_MATCH_SCTP
+ tristate '"sctp" protocol match support'
+ depends on NETFILTER_XTABLES
+ help
+ With this option enabled, you will be able to use the
+ `sctp' match in order to match on SCTP source/destination ports
+ and SCTP chunk types.
+
+ If you want to compile it as a module, say M here and read
+ <file:Documentation/modules.txt>. If unsure, say `N'.
+
+config NETFILTER_XT_MATCH_STATE
+ tristate '"state" match support'
+ depends on NETFILTER_XTABLES
+ depends on IP_NF_CONNTRACK || NF_CONNTRACK
+ help
+ Connection state matching allows you to match packets based on their
+ relationship to a tracked connection (ie. previous packets). This
+ is a powerful tool for packet classification.
+
+ To compile it as a module, choose M here. If unsure, say N.
+
+config NETFILTER_XT_MATCH_STRING
+ tristate '"string" match support'
+ depends on NETFILTER_XTABLES
+ select TEXTSEARCH
+ select TEXTSEARCH_KMP
+ select TEXTSEARCH_BM
+ select TEXTSEARCH_FSM
+ help
+ This option adds a `string' match, which allows you to look for
+ pattern matchings in packets.
+
+ To compile it as a module, choose M here. If unsure, say N.
+
+config NETFILTER_XT_MATCH_TCPMSS
+ tristate '"tcpmss" match support'
+ depends on NETFILTER_XTABLES
+ help
+ This option adds a `tcpmss' match, which allows you to examine the
+ MSS value of TCP SYN packets, which control the maximum packet size
+ for that connection.
+
+ To compile it as a module, choose M here. If unsure, say N.

+ * The TIPC locking policy is designed to ensure a very fine locking
+ * granularity, permitting complete parallel access to individual
+ * port and node/link instances. The code consists of three major
+ * locking domains, each protected with their own disjunct set of locks.
+ *
+ * 1: The routing hierarchy.
+ * Comprises the structures 'zone', 'cluster', 'node', 'link'
+ * and 'bearer'. The whole hierarchy is protected by a big
+ * read/write lock, tipc_net_lock, to enssure that nothing is added
+ * or removed while code is accessing any of these structures.
+ * This layer must not be called from the two others while they
+ * hold any of their own locks.
+ * Neither must it itself do any upcalls to the other two before
+ * it has released tipc_net_lock and other protective locks.
+ *
+ * Within the tipc_net_lock domain there are two sub-domains;'node' and
+ * 'bearer', where local write operations are permitted,
+ * provided that those are protected by individual spin_locks
+ * per instance. Code holding tipc_net_lock(read) and a node spin_lock
+ * is permitted to poke around in both the node itself and its
+ * subordinate links. I.e, it can update link counters and queues,
+ * change link state, send protocol messages, and alter the
+ * "active_links" array in the node; but it can _not_ remove a link
+ * or a node from the overall structure.
+ * Correspondingly, individual bearers may change status within a
+ * tipc_net_lock(read), protected by an individual spin_lock ber bearer
+ * instance, but it needs tipc_net_lock(write) to remove/add any bearers.
+ *
+ *
+ * 2: The transport level of the protocol.
+ * This consists of the structures port, (and its user level
+ * representations, such as user_port and tipc_sock), reference and
+ * tipc_user (port.c, reg.c, socket.c).
+ *
+ * This layer has four different locks:
+ * - The tipc_port spin_lock. This is protecting each port instance
+ * from parallel data access and removal. Since we can not place
+ * this lock in the port itself, it has been placed in the
+ * corresponding reference table entry, which has the same life
+ * cycle as the module. This entry is difficult to access from
+ * outside the TIPC core, however, so a pointer to the lock has
+ * been added in the port instance, -to be used for unlocking
+ * only.
+ * - A read/write lock to protect the reference table itself (teg.c).
+ * (Nobody is using read-only access to this, so it can just as
+ * well be changed to a spin_lock)
+ * - A spin lock to protect the registry of kernel/driver users (reg.c)
+ * - A global spin_lock (tipc_port_lock), which only task is to ensure
+ * consistency where more than one port is involved in an operation,
+ * i.e., whe a port is part of a linked list of ports.
+ * There are two such lists; 'port_list', which is used for management,
+ * and 'wait_list', which is used to queue ports during congestion.
+ *
+ * 3: The name table (name_table.c, name_distr.c, subscription.c)
+ * - There is one big read/write-lock (tipc_nametbl_lock) protecting the
+ * overall name table structure. Nothing must be added/removed to
+ * this structure without holding write access to it.
+ * - There is one local spin_lock per sub_sequence, which can be seen
+ * as a sub-domain to the tipc_nametbl_lock domain. It is used only
+ * for translation operations, and is needed because a translation
+ * steps the root of the 'publication' linked list between each lookup.
+ * This is always used within the scope of a tipc_nametbl_lock(read).
+ * - A local spin_lock protecting the queue of subscriber events.
