+Date: July 2010
+Contact: Thomas Renninger <trenn@suse.de>
+Description:
+
+General information like which GPE is assigned to the EC and whether
+the global lock should get used.
+Knowing the EC GPE one can watch the amount of HW events related to
+the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
+/sys/firmware/acpi/interrupts/gpeXY
+
+The io file is binary and a userspace tool located here:
+ftp://ftp.suse.com/pub/people/trenn/sources/ec/
+should get used to read out the 256 Embedded Controller registers
+or writing to them.
+
+CAUTION: Do not write to the Embedded Controller if you don't know
+what you are doing! Rebooting afterwards also is a good idea.
+This can influence the way your machine is cooled and fans may
+not get switched on again after you did a wrong write.

+
+<para>The LIRC device interface is a bi-directional interface for
+transporting raw IR data between userspace and kernelspace. Fundamentally,
+it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
+of standard struct file_operations defined on it. With respect to
+transporting raw IR data to and fro, the essential fops are read, write
+and ioctl.</para>

+<title>LIRC read fop</title>
+
+<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and what
+mode has been selected. lircd obtains supported modes and sets the active mode
+via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
+preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
+describing an IR signal are read from the chardev.</para>

+<section id="lirc_write">
+<title>LIRC write fop</title>
+
+<para>The data written to the chardev is a pulse/space sequence of integer
+values. Pulses and spaces are only marked implicitly by their position. The
+data must start and end with a pulse, therefore, the data must always include
+an unevent number of samples. The write function must block until the data has
+been transmitted by the hardware.</para>
+</section>
+
+<section id="lirc_ioctl">
+<title>LIRC ioctl fop</title>
+
+<para>The LIRC device's ioctl definition is bound by the ioctl function
+definition of struct file_operations, leaving us with an unsigned int
+for the ioctl command and an unsigned long for the arg. For the purposes
+of ioctl portability across 32-bit and 64-bit, these values are capped
+to their 32-bit sizes.</para>
+
+<para>The following ioctls can be used to change specific hardware settings.
+In general each driver should have a default set of settings. The driver
+implementation is expected to re-apply the default settings when the device
+is closed by user-space, so that every application opening the device can rely
+on working with the default settings initially.</para>

+--- What is AppArmor? ---
+
+AppArmor is MAC style security extension for the Linux kernel. It implements
+a task centered policy, with task "profiles" being created and loaded
+from user space. Tasks on the system that do not have a profile defined for
+them run in an unconfined state which is equivalent to standard Linux DAC
+permissions.
+
+--- How to enable/disable ---
+
+set CONFIG_SECURITY_APPARMOR=y
+
+If AppArmor should be selected as the default security module then
+ set CONFIG_DEFAULT_SECURITY="apparmor"
+ and CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1
+
+Build the kernel
+
+If AppArmor is not the default security module it can be enabled by passing
+security=apparmor on the kernel's command line.
+
+If AppArmor is the default security module it can be disabled by passing
+apparmor=0, security=XXXX (where XXX is valid security module), on the
+kernel's command line
+
+For AppArmor to enforce any restrictions beyond standard Linux DAC permissions
+policy must be loaded into the kernel from user space (see the Documentation
+and tools links).

------------

+In order to utilize the full power of the new multi-touch and multi-user
+devices, a way to report detailed data from multiple contacts, i.e.,
+objects in direct contact with the device surface, is needed. This
+document describes the multi-touch (MT) protocol which allows kernel
+drivers to report details for an arbitrary number of contacts.
+
+The protocol is divided into two types, depending on the capabilities of the
+hardware. For devices handling anonymous contacts (type A), the protocol
+describes how to send the raw data for all contacts to the receiver. For
+devices capable of tracking identifiable contacts (type B), the protocol
+describes how to send updates for individual contacts via event slots.
-Usage
------
+Protocol Usage
+--------------
-Anonymous finger details are sent sequentially as separate packets of ABS
-events. Only the ABS_MT events are recognized as part of a finger
-packet. The end of a packet is marked by calling the input_mt_sync()
-function, which generates a SYN_MT_REPORT event. This instructs the
-receiver to accept the data for the current finger and prepare to receive
-another. The end of a multi-touch transfer is marked by calling the usual
+Contact details are sent sequentially as separate packets of ABS_MT
+events. Only the ABS_MT events are recognized as part of a contact
+packet. Since these events are ignored by current single-touch (ST)
+applications, the MT protocol can be implemented on top of the ST protocol
+in an existing driver.
+
+Drivers for type A devices separate contact packets by calling
+input_mt_sync() at the end of each packet. This generates a SYN_MT_REPORT
+event, which instructs the receiver to accept the data for the current
+contact and prepare to receive another.
+
+Drivers for type B devices separate contact packets by calling
+input_mt_slot(), with a slot as argument, at the beginning of each packet.
+This generates an ABS_MT_SLOT event, which instructs the receiver to
+prepare for updates of the given slot.
+
+All drivers mark the end of a multi-touch transfer by calling the usual
input_sync() function. This instructs the receiver to act upon events
-accumulated since last EV_SYN/SYN_REPORT and prepare to receive a new
-set of events/packets.
+accumulated since last EV_SYN/SYN_REPORT and prepare to receive a new set
+of events/packets.
+
+The main difference between the stateless type A protocol and the stateful
+type B slot protocol lies in the usage of identifiable contacts to reduce
+the amount of data sent to userspace. The slot protocol requires the use of
+the ABS_MT_TRACKING_ID, either provided by the hardware or computed from
+the raw data [5].
+
+For type A devices, the kernel driver should generate an arbitrary
+enumeration of the full set of anonymous contacts currently on the
+surface. The order in which the packets appear in the event stream is not
+important. Event filtering and finger tracking is left to user space [3].
+
+For type B devices, the kernel driver should associate a slot with each
+identified contact, and use that slot to propagate changes for the contact.
+Creation, replacement and destruction of contacts is achieved by modifying
+the ABS_MT_TRACKING_ID of the associated slot. A non-negative tracking id
+is interpreted as a contact, and the value -1 denotes an unused slot. A
+tracking id not previously present is considered new, and a tracking id no
+longer present is considered removed. Since only changes are propagated,
+the full state of each initiated contact has to reside in the receiving
+end. Upon receiving an MT event, one simply updates the appropriate
+attribute of the current slot.
+
+
+Protocol Example A
+------------------
+
+Here is what a minimal event sequence for a two-contact touch would look
+like for a type A device:
+
+ ABS_MT_POSITION_X x[0]
+ ABS_MT_POSITION_Y y[0]
+ SYN_MT_REPORT
+ ABS_MT_POSITION_X x[1]
+ ABS_MT_POSITION_Y y[1]
+ SYN_MT_REPORT
+ SYN_REPORT
+
+The sequence after moving one of the contacts looks exactly the same; the
+raw data for all present contacts are sent between every synchronization
+with SYN_REPORT.
+
+Here is the sequence after lifting the first contact:
+
+ ABS_MT_POSITION_X x[1]
+ ABS_MT_POSITION_Y y[1]
+ SYN_MT_REPORT
+ SYN_REPORT
+
+And here is the sequence after lifting the second contact:
+
+ SYN_MT_REPORT
+ SYN_REPORT
+
+If the driver reports one of BTN_TOUCH or ABS_PRESSURE in addition to the
+ABS_MT events, the last SYN_MT_REPORT event may be omitted. Otherwise, the
+last SYN_REPORT will be dropped by the input core, resulting in no
+zero-contact event reaching userland.
+
+
+Protocol Example B
+------------------
+
+Here is what a minimal event sequence for a two-contact touch would look
+like for a type B device:
+
+ ABS_MT_SLOT 0
+ ABS_MT_TRACKING_ID 45
+ ABS_MT_POSITION_X x[0]
+ ABS_MT_POSITION_Y y[0]
+ ABS_MT_SLOT 1
+ ABS_MT_TRACKING_ID 46
+ ABS_MT_POSITION_X x[1]
+ ABS_MT_POSITION_Y y[1]
+ SYN_REPORT
+
+Here is the sequence after moving contact 45 in the x direction:
+
+ ABS_MT_SLOT 0
+ ABS_MT_POSITION_X x[0]
+ SYN_REPORT
+
+Here is the sequence after lifting the contact in slot 0:
+
+ ABS_MT_TRACKING_ID -1
+ SYN_REPORT
+
+The slot being modified is already 0, so the ABS_MT_SLOT is omitted. The
+message removes the association of slot 0 with contact 45, thereby
+destroying contact 45 and freeing slot 0 to be reused for another contact.
+
+Finally, here is the sequence after lifting the second contact:
+
+ ABS_MT_SLOT 1
+ ABS_MT_TRACKING_ID -1
+ SYN_REPORT
+
+
+Event Usage

A set of ABS_MT events with the desired properties is defined. The events
are divided into categories, to allow for partial implementation. The

+Emulating cr0.wp
+================
+
+If tdp is not enabled, the host must keep cr0.wp=1 so page write protection
+works for the guest kernel, not guest guest userspace. When the guest
+cr0.wp=1, this does not present a problem. However when the guest cr0.wp=0,
+we cannot map the permissions for gpte.u=1, gpte.w=0 to any spte (the
+semantics require allowing any guest kernel access plus user read access).
+
+We handle this by mapping the permissions to two possible sptes, depending
+on fault type:
+
+- kernel write fault: spte.u=0, spte.w=1 (allows full kernel access,
+ disallows user access)
+- read fault: spte.u=1, spte.w=0 (allows full read access, disallows kernel
+ write access)
+
+(user write faults generate a #PF)
+
+Large pages
+===========
+
+The mmu supports all combinations of large and small guest and host pages.
+Supported page sizes include 4k, 2M, 4M, and 1G. 4M pages are treated as
+two separate 2M pages, on both guest and host, since the mmu always uses PAE
+paging.
+
+To instantiate a large spte, four constraints must be satisfied:
+
+- the spte must point to a large host page
+- the guest pte must be a large pte of at least equivalent size (if tdp is
+ enabled, there is no guest pte and this condition is satisified)
+- if the spte will be writeable, the large page frame may not overlap any
+ write-protected pages
+- the guest page must be wholly contained by a single memory slot
+
+To check the last two conditions, the mmu maintains a ->write_count set of
+arrays for each memory slot and large page size. Every write protected page
+causes its write_count to be incremented, thus preventing instantiation of
+a large spte. The frames at the end of an unaligned memory slot have
+artificically inflated ->write_counts so they can never be instantiated.

+KVM-specific MSRs.
+Glauber Costa <glommer@redhat.com>, Red Hat Inc, 2010
+=====================================================
+
+KVM makes use of some custom MSRs to service some requests.
+At present, this facility is only used by kvmclock.
+
+Custom MSRs have a range reserved for them, that goes from
+0x4b564d00 to 0x4b564dff. There are MSRs outside this area,
+but they are deprecated and their use is discouraged.
+
+Custom MSR list
+--------
+
+The current supported Custom MSR list is:
+
+MSR_KVM_WALL_CLOCK_NEW: 0x4b564d00
+
+ data: 4-byte alignment physical address of a memory area which must be
+ in guest RAM. This memory is expected to hold a copy of the following
+ structure:
+
+ struct pvclock_wall_clock {
+ u32 version;
+ u32 sec;
+ u32 nsec;
+ } __attribute__((__packed__));
+
+ whose data will be filled in by the hypervisor. The hypervisor is only
+ guaranteed to update this data at the moment of MSR write.
+ Users that want to reliably query this information more than once have
+ to write more than once to this MSR. Fields have the following meanings:
+
+ version: guest has to check version before and after grabbing
+ time information and check that they are both equal and even.
+ An odd version indicates an in-progress update.
+
+ sec: number of seconds for wallclock.
+
+ nsec: number of nanoseconds for wallclock.
+
+ Note that although MSRs are per-CPU entities, the effect of this
+ particular MSR is global.
+
+ Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+ leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME_NEW: 0x4b564d01
+
+ data: 4-byte aligned physical address of a memory area which must be in
+ guest RAM, plus an enable bit in bit 0. This memory is expected to hold
+ a copy of the following structure:
+
+ struct pvclock_vcpu_time_info {
+ u32 version;
+ u32 pad0;
+ u64 tsc_timestamp;
+ u64 system_time;
+ u32 tsc_to_system_mul;
+ s8 tsc_shift;
+ u8 flags;
+ u8 pad[2];
+ } __attribute__((__packed__)); /* 32 bytes */
+
+ whose data will be filled in by the hypervisor periodically. Only one
+ write, or registration, is needed for each VCPU. The interval between
+ updates of this structure is arbitrary and implementation-dependent.
+ The hypervisor may update this structure at any time it sees fit until
+ anything with bit0 == 0 is written to it.
+
+ Fields have the following meanings:
+
+ version: guest has to check version before and after grabbing
+ time information and check that they are both equal and even.
+ An odd version indicates an in-progress update.
+
+ tsc_timestamp: the tsc value at the current VCPU at the time
+ of the update of this structure. Guests can subtract this value
+ from current tsc to derive a notion of elapsed time since the
+ structure update.
+
+ system_time: a host notion of monotonic time, including sleep
+ time at the time this structure was last updated. Unit is
+ nanoseconds.
+
+ tsc_to_system_mul: a function of the tsc frequency. One has
+ to multiply any tsc-related quantity by this value to get
+ a value in nanoseconds, besides dividing by 2^tsc_shift
+
+ tsc_shift: cycle to nanosecond divider, as a power of two, to
+ allow for shift rights. One has to shift right any tsc-related
+ quantity by this value to get a value in nanoseconds, besides
+ multiplying by tsc_to_system_mul.
+
+ With this information, guests can derive per-CPU time by
+ doing:
+
+ time = (current_tsc - tsc_timestamp)
+ time = (time * tsc_to_system_mul) >> tsc_shift
+ time = time + system_time
+
+ flags: bits in this field indicate extended capabilities
+ coordinated between the guest and the hypervisor. Availability
+ of specific flags has to be checked in 0x40000001 cpuid leaf.
+ Current flags are:
+
+ flag bit | cpuid bit | meaning
+ -------------------------------------------------------------
+ | | time measures taken across
+ 0 | 24 | multiple cpus are guaranteed to
+ | | be monotonic
+ -------------------------------------------------------------
+
+ Availability of this MSR must be checked via bit 3 in 0x4000001 cpuid
+ leaf prior to usage.
+
+
+MSR_KVM_WALL_CLOCK: 0x11
+
+ data and functioning: same as MSR_KVM_WALL_CLOCK_NEW. Use that instead.
+
+ This MSR falls outside the reserved KVM range and may be removed in the
+ future. Its usage is deprecated.
+
+ Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+ leaf prior to usage.
+
+MSR_KVM_SYSTEM_TIME: 0x12
+
+ data and functioning: same as MSR_KVM_SYSTEM_TIME_NEW. Use that instead.
+
+ This MSR falls outside the reserved KVM range and may be removed in the
+ future. Its usage is deprecated.
+
+ Availability of this MSR must be checked via bit 0 in 0x4000001 cpuid
+ leaf prior to usage.
+
+ The suggested algorithm for detecting kvmclock presence is then:
+
+ if (!kvm_para_available()) /* refer to cpuid.txt */
+ return NON_PRESENT;
+
+ flags = cpuid_eax(0x40000001);
+ if (flags & 3) {
+ msr_kvm_system_time = MSR_KVM_SYSTEM_TIME_NEW;
+ msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK_NEW;
+ return PRESENT;
+ } else if (flags & 0) {
+ msr_kvm_system_time = MSR_KVM_SYSTEM_TIME;
+ msr_kvm_wall_clock = MSR_KVM_WALL_CLOCK;
+ return PRESENT;
+ } else

+Review checklist for kvm patches
+================================
+
+1. The patch must follow Documentation/CodingStyle and
+ Documentation/SubmittingPatches.
+
+2. Patches should be against kvm.git master branch.
+
+3. If the patch introduces or modifies a new userspace API:
+ - the API must be documented in Documentation/kvm/api.txt
+ - the API must be discoverable using KVM_CHECK_EXTENSION
+
+4. New state must include support for save/restore.
+
+5. New features must default to off (userspace should explicitly request them).
+ Performance improvements can and should default to on.
+
+6. New cpu features should be exposed via KVM_GET_SUPPORTED_CPUID2
+
+7. Emulator changes should be accompanied by unit tests for qemu-kvm.git
+ kvm/test directory.
+
+8. Changes should be vendor neutral when possible. Changes to common code
+ are better than duplicating changes to vendor code.
+
+9. Similarly, prefer changes to arch independent code than to arch dependent
+ code.
+
+10. User/kernel interfaces and guest/host interfaces must be 64-bit clean
+ (all variables and sizes naturally aligned on 64-bit; use specific types
+ only - u64 rather than ulong).
+
+11. New guest visible features must either be documented in a hardware manual
+ or be accompanied by documentation.
+
+12. Features must be robust against reset and kexec - for example, shared
+ host/guest memory must be unshared to prevent the host from writing to
+ guest memory that the guest has not reserved for this purpose.

+3.5 Overriding Configuration for Special Cases
+----------------------------------------------
+When using the bonding driver, the physical port which transmits a frame is
+typically selected by the bonding driver, and is not relevant to the user or
+system administrator. The output port is simply selected using the policies of
+the selected bonding mode. On occasion however, it is helpful to direct certain
+classes of traffic to certain physical interfaces on output to implement
+slightly more complex policies. For example, to reach a web server over a
+bonded interface in which eth0 connects to a private network, while eth1
+connects via a public network, it may be desirous to bias the bond to send said
+traffic over eth0 first, using eth1 only as a fall back, while all other traffic
+can safely be sent over either interface. Such configurations may be achieved
+using the traffic control utilities inherent in linux.
-4. Querying Bonding Configuration
+By default the bonding driver is multiqueue aware and 16 queues are created
+when the driver initializes (see Documentation/networking/multiqueue.txt
+for details). If more or less queues are desired the module parameter
+tx_queues can be used to change this value. There is no sysfs parameter
+available as the allocation is done at module init time.
+
+The output of the file /proc/net/bonding/bondX has changed so the output Queue
+ID is now printed for each slave:
+
+Bonding Mode: fault-tolerance (active-backup)
+Primary Slave: None
+Currently Active Slave: eth0
+MII Status: up
+MII Polling Interval (ms): 0
+Up Delay (ms): 0
+Down Delay (ms): 0
+
+Slave Interface: eth0
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cb
+Slave queue ID: 0
+
+Slave Interface: eth1
+MII Status: up
+Link Failure Count: 0
+Permanent HW addr: 00:1a:a0:12:8f:cc
+Slave queue ID: 2
+
+The queue_id for a slave can be set using the command:
+
+# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
+
+Any interface that needs a queue_id set should set it with multiple calls
+like the one above until proper priorities are set for all interfaces. On
+distributions that allow configuration via initscripts, multiple 'queue_id'
+arguments can be added to BONDING_OPTS to set all needed slave queues.
+
+These queue id's can be used in conjunction with the tc utility to configure
+a multiqueue qdisc and filters to bias certain traffic to transmit on certain
+slave devices. For instance, say we wanted, in the above configuration to
+force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
+device. The following commands would accomplish this:
+
+# tc qdisc add dev bond0 handle 1 root multiq
+
+# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
+ 192.168.1.100 action skbedit queue_mapping 2
+
+These commands tell the kernel to attach a multiqueue queue discipline to the
+bond0 interface and filter traffic enqueued to it, such that packets with a dst
+ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
+This value is then passed into the driver, causing the normal output path
+selection policy to be overridden, selecting instead qid 2, which maps to eth1.
+
+Note that qid values begin at 1. Qid 0 is reserved to initiate to the driver
+that normal output policy selection should take place. One benefit to simply
+leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
+driver that is now present. This awareness allows tc filters to be placed on
+slave devices as well as bond devices and the bonding driver will simply act as
+a pass-through for selecting output queues on the slave device rather than
+output port selection.
+
+This feature first appeared in bonding driver version 3.7.0 and support for
+output slave selection was limited to round-robin and active-backup modes.

+- CAIF SPI porting -
+
+- CAIF SPI basics:
+
+Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
+Two extra GPIOs have been added in order to negotiate the transfers
+ between the master and the slave. The minimum requirement for running
+CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
+Please note that running as a slave implies that you need to keep up
+with the master clock. An overrun or underrun event is fatal.
+
+- CAIF SPI framework:
+
+To make porting as easy as possible, the CAIF SPI has been divided in
+two parts. The first part (called the interface part) deals with all
+generic functionality such as length framing, SPI frame negotiation
+and SPI frame delivery and transmission. The other part is the CAIF
+SPI slave device part, which is the module that you have to write if
+you want to run SPI CAIF on a new hardware. This part takes care of
+the physical hardware, both with regard to SPI and to GPIOs.
+
+- Implementing a CAIF SPI device:
+
+ - Functionality provided by the CAIF SPI slave device:
+
+ In order to implement a SPI device you will, as a minimum,
+ need to implement the following
+ functions:
+
+ int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
+
+ This function is called by the CAIF SPI interface to give
+ you a chance to set up your hardware to be ready to receive
+ a stream of data from the master. The xfer structure contains
+ both physical and logical adresses, as well as the total length
+ of the transfer in both directions.The dev parameter can be used
+ to map to different CAIF SPI slave devices.
+
+ void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
+
+ This function is called by the CAIF SPI interface when the output
+ (SPI_INT) GPIO needs to change state. The boolean value of the xfer
+ variable indicates whether the GPIO should be asserted (HIGH) or
+ deasserted (LOW). The dev parameter can be used to map to different CAIF
+ SPI slave devices.
+
+ - Functionality provided by the CAIF SPI interface:
+
+ void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
+
+ This function is called by the CAIF SPI slave device in order to
+ signal a change of state of the input GPIO (SS) to the interface.
+ Only active edges are mandatory to be reported.
+ This function can be called from IRQ context (recommended in order
+ not to introduce latency). The ifc parameter should be the pointer
+ returned from the platform probe function in the SPI device structure.
+
+ void (*xfer_done_cb) (struct cfspi_ifc *ifc);
+
+ This function is called by the CAIF SPI slave device in order to
+ report that a transfer is completed. This function should only be
+ called once both the transmission and the reception are completed.
+ This function can be called from IRQ context (recommended in order
+ not to introduce latency). The ifc parameter should be the pointer
+ returned from the platform probe function in the SPI device structure.
+
+ - Connecting the bits and pieces:
+
+ - Filling in the SPI slave device structure:
+
+ Connect the necessary callback functions.
+ Indicate clock speed (used to calculate toggle delays).
+ Chose a suitable name (helps debugging if you use several CAIF
+ SPI slave devices).
+ Assign your private data (can be used to map to your structure).
+
+ - Filling in the SPI slave platform device structure:
+ Add name of driver to connect to ("cfspi_sspi").
+ Assign the SPI slave device structure as platform data.
+
+- Padding:
+
+In order to optimize throughput, a number of SPI padding options are provided.
+Padding can be enabled independently for uplink and downlink transfers.
+Padding can be enabled for the head, the tail and for the total frame size.
+The padding needs to be correctly configured on both sides of the link.
+The padding can be changed via module parameters in cfspi_sspi.c or via
+the sysfs directory of the cfspi_sspi driver (before device registration).

-The cpumask describes which processors will be used to execute work

+The workqueue wq is where the work will actually be done; it should be

+
+To allocate a padata instance with the cpu_possible_mask for both
+cpumasks this helper function can be used:
+
+ struct padata_instance *padata_alloc_possible(struct workqueue_struct *wq);
+
+Note: Padata maintains two kinds of cpumasks internally. The user supplied
+cpumasks, submitted by padata_alloc/padata_alloc_possible and the 'usable'
+cpumasks. The usable cpumasks are always the subset of active cpus in the
+user supplied cpumasks, these are the cpumasks padata actually use. So
+it is legal to supply a cpumask to padata that contains offline cpus.
+Once a offline cpu in the user supplied cpumask comes online, padata
+is going to use it.
There are functions for enabling and disabling the instance:
- void padata_start(struct padata_instance *pinst);
+ int padata_start(struct padata_instance *pinst);
void padata_stop(struct padata_instance *pinst);
-These functions literally do nothing beyond setting or clearing the
-"padata_start() was called" flag; if that flag is not set, other functions
-will refuse to work.
+These functions are setting or clearing the "PADATA_INIT" flag;
+if that flag is not set, other functions will refuse to work.
+padata_start returns zero on success (flag set) or -EINVAL if the
+padata cpumask contains no active cpu (flag not set).
+padata_stop clears the flag and blocks until the padata instance
+is unused.
The list of CPUs to be used can be adjusted with these functions:
- int padata_set_cpumask(struct padata_instance *pinst,
+ int padata_set_cpumasks(struct padata_instance *pinst,
+ cpumask_var_t pcpumask,
+ cpumask_var_t cbcpumask);
+ int padata_set_cpumask(struct padata_instance *pinst, int cpumask_type,
cpumask_var_t cpumask);
- int padata_add_cpu(struct padata_instance *pinst, int cpu);
- int padata_remove_cpu(struct padata_instance *pinst, int cpu);
+ int padata_add_cpu(struct padata_instance *pinst, int cpu, int mask);
+ int padata_remove_cpu(struct padata_instance *pinst, int cpu, int mask);
-Changing the CPU mask has the look of an expensive operation, though, so it
-probably should not be done with great frequency.
+Changing the CPU masks are expensive operations, though, so it should not be
+done with great frequency.
+
+It's possible to change both cpumasks of a padata instance with
+padata_set_cpumasks by specifying the cpumasks for parallel execution (pcpumask)
+and for the serial callback function (cbcpumask). padata_set_cpumask is to
+change just one of the cpumasks. Here cpumask_type is one of PADATA_CPU_SERIAL,
+PADATA_CPU_PARALLEL and cpumask specifies the new cpumask to use.
+To simply add or remove one cpu from a certain cpumask the functions
+padata_add_cpu/padata_remove_cpu are used. cpu specifies the cpu to add or
+remove and mask is one of PADATA_CPU_SERIAL, PADATA_CPU_PARALLEL.
+
+If a user is interested in padata cpumask changes, he can register to
+the padata cpumask change notifier:
+
+ int padata_register_cpumask_notifier(struct padata_instance *pinst,
+ struct notifier_block *nblock);
+
+To unregister from that notifier:
+
+ int padata_unregister_cpumask_notifier(struct padata_instance *pinst,
+ struct notifier_block *nblock);
+
+The padata cpumask change notifier notifies about changes of the usable
+cpumasks, i.e. the subset of active cpus in the user supplied cpumask.
+
+Padata calls the notifier chain with:
+
+ blocking_notifier_call_chain(&pinst->cpumask_change_notifier,
+ notification_mask,
+ &pd_new->cpumask);
+
+Here cpumask_change_notifier is registered notifier, notification_mask
+is one of PADATA_CPU_SERIAL, PADATA_CPU_PARALLEL and cpumask is a pointer
+to a struct padata_cpumask that contains the new cpumask informations.

+HPSA - Hewlett Packard Smart Array driver
+-----------------------------------------
+
+This file describes the hpsa SCSI driver for HP Smart Array controllers.
+The hpsa driver is intended to supplant the cciss driver for newer
+Smart Array controllers. The hpsa driver is a SCSI driver, while the
+cciss driver is a "block" driver. Actually cciss is both a block
+driver (for logical drives) AND a SCSI driver (for tape drives). This
+"split-brained" design of the cciss driver is a source of excess
+complexity and eliminating that complexity is one of the reasons
+for hpsa to exist.
+
+Supported devices:
+------------------
+
+Smart Array P212
+Smart Array P410
+Smart Array P410i
+Smart Array P411
+Smart Array P812
+Smart Array P712m
+Smart Array P711m
+StorageWorks P1210m
+
+Additionally, older Smart Arrays may work with the hpsa driver if the kernel
+boot parameter "hpsa_allow_any=1" is specified, however these are not tested
+nor supported by HP with this driver. For older Smart Arrays, the cciss
+driver should still be used.
+
+HPSA specific entries in /sys
+-----------------------------
+
+ In addition to the generic SCSI attributes available in /sys, hpsa supports
+ the following attributes:
+
+ HPSA specific host attributes:
+ ------------------------------
+
+ /sys/class/scsi_host/host*/rescan
+ /sys/class/scsi_host/host*/firmware_revision
+
+ the host "rescan" attribute is a write only attribute. Writing to this
+ attribute will cause the driver to scan for new, changed, or removed devices
+ (e.g. hot-plugged tape drives, or newly configured or deleted logical drives,
+ etc.) and notify the SCSI midlayer of any changes detected. Normally this is
+ triggered automatically by HP's Array Configuration Utility (either the GUI or
+ command line variety) so for logical drive changes, the user should not
+ normally have to use this. It may be useful when hot plugging devices like
+ tape drives, or entire storage boxes containing pre-configured logical drives.
+
+ The "firmware_revision" attribute contains the firmware version of the Smart Array.
+ For example:
+
+ root@host:/sys/class/scsi_host/host4# cat firmware_revision
+ 7.14
+
+ HPSA specific disk attributes:
+ ------------------------------
+
+ /sys/class/scsi_disk/c:b:t:l/device/unique_id
+ /sys/class/scsi_disk/c:b:t:l/device/raid_level
+ /sys/class/scsi_disk/c:b:t:l/device/lunid
+
+ (where c:b:t:l are the controller, bus, target and lun of the device)
+
+ For example:
+
+ root@host:/sys/class/scsi_disk/4:0:0:0/device# cat unique_id
+ 600508B1001044395355323037570F77
+ root@host:/sys/class/scsi_disk/4:0:0:0/device# cat lunid
+ 0x0000004000000000
+ root@host:/sys/class/scsi_disk/4:0:0:0/device# cat raid_level
+ RAID 0
+
+HPSA specific ioctls:
+---------------------
+
+ For compatibility with applications written for the cciss driver, many, but
+ not all of the ioctls supported by the cciss driver are also supported by the
+ hpsa driver. The data structures used by these are described in
+ include/linux/cciss_ioctl.h
+
+ CCISS_DEREGDISK
+ CCISS_REGNEWDISK
+ CCISS_REGNEWD
+
+ The above three ioctls all do exactly the same thing, which is to cause the driver
+ to rescan for new devices. This does exactly the same thing as writing to the
+ hpsa specific host "rescan" attribute.
+
+ CCISS_GETPCIINFO
+
+ Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).
+
+ CCISS_GETDRIVVER
+
+ Returns driver version in three bytes encoded as:
+ (major_version << 16) | (minor_version << 8) | (subminor_version)
+
+ CCISS_PASSTHRU
+ CCISS_BIG_PASSTHRU
+
+ Allows "BMIC" and "CISS" commands to be passed through to the Smart Array.
+ These are used extensively by the HP Array Configuration Utility, SNMP storage
+ agents, etc. See cciss_vol_status at http://cciss.sf.net for some examples.

+ * LPC32xx clock management driver overview
+ *
+ * The LPC32XX contains a number of high level system clocks that can be
+ * generated from different sources. These system clocks are used to
+ * generate the CPU and bus rates and the individual peripheral clocks in
+ * the system. When Linux is started by the boot loader, the system
+ * clocks are already running. Stopping a system clock during normal
+ * Linux operation should never be attempted, as peripherals that require
+ * those clocks will quit working (ie, DRAM).
+ *
+ * The LPC32xx high level clock tree looks as follows. Clocks marked with
+ * an asterisk are always on and cannot be disabled. Clocks marked with
+ * an ampersand can only be disabled in CPU suspend mode. Clocks marked
+ * with a caret are always on if it is the selected clock for the SYSCLK
+ * source. The clock that isn't used for SYSCLK can be enabled and
+ * disabled normally.
+ * 32KHz oscillator*
+ * / | \
+ * RTC* PLL397^ TOUCH
+ * /
+ * Main oscillator^ /
+ * | \ /
+ * | SYSCLK&
+ * | \
+ * | \
+ * USB_PLL HCLK_PLL&
+ * | | |
+ * USB host/device PCLK& |
+ * | |
+ * Peripherals
+ *
+ * The CPU and chip bus rates are derived from the HCLK PLL, which can
+ * generate various clock rates up to 266MHz and beyond. The internal bus
+ * rates (PCLK and HCLK) are generated from dividers based on the HCLK
+ * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate,
+ * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high
+ * level clocks are based on either HCLK or PCLK, but have their own
+ * dividers as part of the IP itself. Because of this, the system clock
+ * rates should not be changed.
+ *
+ * The HCLK PLL is clocked from SYSCLK, which can be derived from the
+ * main oscillator or PLL397. PLL397 generates a rate that is 397 times
+ * the 32KHz oscillator rate. The main oscillator runs at the selected
+ * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate
+ * is normally 13MHz, but depends on the selection of external crystals
+ * or oscillators. If USB operation is required, the main oscillator must
+ * be used in the system.
+ *
+ * Switching SYSCLK between sources during normal Linux operation is not
+ * supported. SYSCLK is preset in the bootloader. Because of the
+ * complexities of clock management during clock frequency changes,
+ * there are some limitations to the clock driver explained below:
+ * - The PLL397 and main oscillator can be enabled and disabled by the
+ * clk_enable() and clk_disable() functions unless SYSCLK is based
+ * on that clock. This allows the other oscillator that isn't driving
+ * the HCLK PLL to be used as another system clock that can be routed
+ * to an external pin.
+ * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with
+ * this driver.
+ * - HCLK and PCLK rates cannot be changed as part of this driver.
+ * - Most peripherals have their own dividers are part of the peripheral
+ * block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates
+ * will also impact the individual peripheral rates.

+/*
+ * LPC32XX CPU and system power management
+ *
+ * The LCP32XX has three CPU modes for controlling system power: run,
+ * direct-run, and halt modes. When switching between halt and run modes,
+ * the CPU transistions through direct-run mode. For Linux, direct-run
+ * mode is not used in normal operation. Halt mode is used when the
+ * system is fully suspended.
+ *
+ * Run mode:
+ * The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are
+ * derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from
+ * the HCLK_PLL rate. Linux runs in this mode.
+ *
+ * Direct-run mode:
+ * The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from
+ * SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK
+ * source or the frequency of the main oscillator. In this mode, the
+ * HCLK_PLL can be safely enabled, changed, or disabled.
+ *
+ * Halt mode:
+ * SYSCLK is gated off and the CPU and system clocks are halted.
+ * Peripherals based on the 32KHz oscillator clock (ie, RTC, touch,
+ * key scanner, etc.) still operate if enabled. In this state, an enabled
+ * system event (ie, GPIO state change, RTC match, key press, etc.) will
+ * wake the system up back into direct-run mode.
+ *
+ * DRAM refresh
+ * DRAM clocking and refresh are slightly different for systems with DDR
+ * DRAM or regular SDRAM devices. If SDRAM is used in the system, the
+ * SDRAM will still be accessible in direct-run mode. In DDR based systems,
+ * a transistion to direct-run mode will stop all DDR accesses (no clocks).
+ * Because of this, the code to switch power modes and the code to enter
+ * and exit DRAM self-refresh modes must not be executed in DRAM. A small
+ * section of IRAM is used instead for this.
+ *
+ * Suspend is handled with the following logic:
+ * Backup a small area of IRAM used for the suspend code
+ * Copy suspend code to IRAM
+ * Transfer control to code in IRAM
+ * Places DRAMs in self-refresh mode
+ * Enter direct-run mode
+ * Save state of HCLK_PLL PLL
+ * Disable HCLK_PLL PLL
+ * Enter halt mode - CPU and buses will stop
+ * System enters direct-run mode when an enabled event occurs
+ * HCLK PLL state is restored
+ * Run mode is entered
+ * DRAMS are placed back into normal mode
+ * Code execution returns from IRAM
+ * IRAM code are used for suspend is restored
+ * Suspend mode is exited

+ Say N to disable Embedded Controller /sys/kernel/debug interface
+
+ Be aware that using this interface can confuse your Embedded
+ Controller in a way that a normal reboot is not enough. You then
+ have to power of your system, and remove the laptop battery for
+ some seconds.
+ An Embedded Controller typically is available on laptops and reads
+ sensor values like battery state and temperature.
+ The kernel accesses the EC through ACPI parsed code provided by BIOS
+ tables. This option allows to access the EC directly without ACPI
+ code being involved.
+ Thus this option is a debug option that helps to write ACPI drivers
+ and can be used to identify ACPI code or EC firmware bugs.

+ * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers
+ *
+ * Copyright (c) 2010 by Jarod Wilson <jarod@redhat.com>
+ *
+ * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
+ * Conti, Martin Blatter and Daniel Melander, the latter of which was
+ * in turn also based on the lirc_atiusb driver by Paul Miller. The
+ * two mce drivers were merged into one by Jarod Wilson, with transmit
+ * support for the 1st-gen device added primarily by Patrick Calhoun,
+ * with a bit of tweaks by Jarod. Debugging improvements and proper
+ * support for what appears to be 3rd-gen hardware added by Jarod.
+ * Initial port from lirc driver to ir-core drivery by Jarod, based
+ * partially on a port to an earlier proposed IR infrastructure by
+ * Jon Smirl, which included enhancements and simplifications to the
+ * incoming IR buffer parsing routines.

- * STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.

- * Free Software Foundation; either version 2 of the License, or (at your

- * You should have received a copy of the GNU General Public License
- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- * function, made more stable (?)
- *
- * ver 0.21 Nov, 2001. Added gamma correction and white balance,
- * due to Alexander Schwartz. Still trying to
- * improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
- * mike@easysw.com) from GIMP, also used in pencam.
- * Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * Took out sharpen function, ran code through
- * Lindent, and did other minor tweaks to get
- * things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- * Fixed the problem with webcam crashing after
- * two pictures. Changed the way pic is halved to
- * improve quality. Got rid of green line around
- * frame. Fix brightness reset when changing size
- * bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- * Fixed a bug in which the driver sometimes attempted
- * to set to a non-supported size. This allowed
- * gnomemeeting to work.
- * Fixed proc entry removal bug.

- * This is a shameless copy from the USB-cpia driver (linux kernel
- * version 2.3.29 or so, I have no idea what this code actually does ;).
- * Actually it seems to be a copy of a shameless copy of the bttv-driver.
- * Or that is a copy of a shameless copy of ... (To the powers: is there
- * no generic kernel-function to do this sort of stuff?)
- *
- * Yes, it was a shameless copy from the bttv-driver. IIRC, Alan says
- * there will be one, but apparentely not yet -jerdfelt
- *
- * So I copied it again for the ov511 driver -claudio
- *
- * Same for the se401 driver -Jeroen
- *
- * And the STV0680 driver - Kevin

- * The driver registers itself with the rfkill subsystem and
- * the Linux backlight control subsystem.
+ * This driver exports a few files in /sys/devices/platform/compal-laptop/:
+ * wake_up_XXX Whether or not we listen to such wake up events (rw)
+ *
+ * In addition to these platform device attributes the driver
+ * registers itself in the Linux backlight control, power_supply, rfkill
+ * and hwmon subsystem and is available to userspace under:
+ *
+ * /sys/class/backlight/compal-laptop/
+ * /sys/class/power_supply/compal-laptop/
+ * /sys/class/rfkill/rfkillX/
+ * /sys/class/hwmon/hwmonX/
+ *
+ * Notes on the power_supply battery interface:
+ * - the "minimum" design voltage is *the* design voltage
+ * - the ambient temperature is the average battery temperature
+ * and the value is an educated guess (see commented code below)
+ *
*
* This driver might work on other laptops produced by Compal. If you
* want to try it you can pass force=1 as argument to the module which
* will force it to load even when the DMI data doesn't identify the
- * laptop as FL9x.
+ * laptop as compatible.
+ *
+ * Lots of data available at:
+ * http://service1.marasst.com/Compal/JHL90_91/Service%20Manual/
+ * JHL90%20service%20manual-Final-0725.pdf
+ *
+ *
+ *
+ * Support for the Compal JHL90 added by Roald Frederickx
+ * (roald.frederickx@gmail.com):
+ * Driver got large revision. Added functionalities: backlight
+ * power, wake_on_XXX, a hwmon and power_supply interface.
+ *
+ * In case this gets merged into the kernel source: I want to dedicate this
+ * to Kasper Meerts, the awesome guy who showed me Linux and C!

+/*
+ * Some Intel Ibex Peak based platforms support so-called "intelligent
+ * power sharing", which allows the CPU and GPU to cooperate to maximize
+ * performance within a given TDP (thermal design point). This driver
+ * performs the coordination between the CPU and GPU, monitors thermal and
+ * power statistics in the platform, and initializes power monitoring
+ * hardware. It also provides a few tunables to control behavior. Its
+ * primary purpose is to safely allow CPU and GPU turbo modes to be enabled
+ * by tracking power and thermal budget; secondarily it can boost turbo
+ * performance by allocating more power or thermal budget to the CPU or GPU
+ * based on available headroom and activity.
+ *
+ * The basic algorithm is driven by a 5s moving average of tempurature. If
+ * thermal headroom is available, the CPU and/or GPU power clamps may be
+ * adjusted upwards. If we hit the thermal ceiling or a thermal trigger,
+ * we scale back the clamp. Aside from trigger events (when we're critically
+ * close or over our TDP) we don't adjust the clamps more than once every
+ * five seconds.
+ *
+ * The thermal device (device 31, function 6) has a set of registers that
+ * are updated by the ME firmware. The ME should also take the clamp values
+ * written to those registers and write them to the CPU, but we currently
+ * bypass that functionality and write the CPU MSR directly.
+ *
+ * UNSUPPORTED:
+ * - dual MCP configs
+ *
+ * TODO:
+ * - handle CPU hotplug
+ * - provide turbo enable/disable api
+ * - make sure we can write turbo enable/disable reg based on MISC_EN
+ *

+ * The ITE8709 device seems to be the combination of IT8512 superIO chip and

+ * In addition of the embedded micro-controller, the IT8512 chip contains a
+ * CIR module and several other modules. A few modules are directly accessible
+ * by the host CPU, but most of them are only accessible by the
+ * micro-controller. The CIR module is only accessible by the micro-controller.
+ * The battery-backed SRAM module is accessible by the host CPU and the
+ * micro-controller. So one of the MC's firmware role is to act as a bridge
+ * between the host CPU and the CIR module. The firmware implements a kind of
+ * communication protocol using the SRAM module as a shared memory. The IT8512
+ * specification is publicly available on ITE's web site, but the communication
+ * protocol is not, so it was reverse-engineered.

+ * Steve's changes to improve transmission fidelity:
+ * - for systems with the rdtsc instruction and the clock counter, a
+ * send_pule that times the pulses directly using the counter.
+ * This means that the LIRC_SERIAL_TRANSMITTER_LATENCY fudge is
+ * not needed. Measurement shows very stable waveform, even where
+ * PCI activity slows the access to the UART, which trips up other
+ * versions.
+ * - For other system, non-integer-microsecond pulse/space lengths,
+ * done using fixed point binary. So, much more accurate carrier
+ * frequency.
+ * - fine tuned transmitter latency, taking advantage of fractional
+ * microseconds in previous change
+ * - Fixed bug in the way transmitter latency was accounted for by
+ * tuning the pulse lengths down - the send_pulse routine ignored
+ * this overhead as it timed the overall pulse length - so the
+ * pulse frequency was right but overall pulse length was too
+ * long. Fixed by accounting for latency on each pulse/space
+ * iteration.

+ * Streamzap Remote Control driver
+ *
+ * Copyright (c) 2005 Christoph Bartelmus <lirc@bartelmus.de>
+ *
+ * This driver was based on the work of Greg Wickham and Adrian
+ * Dewhurst. It was substantially rewritten to support correct signal
+ * gaps and now maintains a delay buffer, which is used to present
+ * consistent timing behaviour to user space applications. Without the
+ * delay buffer an ugly hack would be required in lircd, which can
+ * cause sluggish signal decoding in certain situations.
+ *
+ * This driver is based on the USB skeleton driver packaged with the
+ * kernel; copyright (C) 2001-2003 Greg Kroah-Hartman (greg@kroah.com)

- This driver allows other kernel drivers access to the
- contents of the restricted access region control registers.
-
- The restricted access region control registers
- (rar_registers) are used to pass address and
- locking information on restricted access regions
- to other drivers that use restricted access regions.
-
- The restricted access regions are regions of memory
- on the Intel MID Platform that are not accessible to
- the x86 processor, but are accessible to dedicated
- processors on board peripheral devices.
-
- The purpose of the restricted access regions is to
- protect sensitive data from compromise by unauthorized
- programs running on the x86 processor.

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ * be lost, thus blocking readers forever.
+ * If this synchronization point is not a mutex, but a spinlock or
+ * spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ * are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ * pure reads. But if they have to fetch many values, it's better to not allow
+ * preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ * (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ * read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ * u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ * spin_lock_bh(...) or other synchronization to get exclusive access
+ * ...
+ * u64_stats_update_begin(&stats->syncp);
+ * stats->bytes64 += len; // non atomic operation
+ * stats->packets64++; // non atomic operation
+ * u64_stats_update_end(&stats->syncp);
+ *
+ * While a consumer (reader) should use following template to get consistent
+ * snapshot for each variable (but no guarantee on several ones)
+ *
+ * u64 tbytes, tpackets;
+ * unsigned int start;
+ *
+ * do {
+ * start = u64_stats_fetch_begin(&stats->syncp);
+ * tbytes = stats->bytes64; // non atomic operation
+ * tpackets = stats->packets64; // non atomic operation
+ * } while (u64_stats_fetch_retry(&stats->syncp, start));

+ *
+ * If a wakeup event occurs when the system is in a sleep state, it simply is
+ * woken up. In turn, if an event that would wake the system up from a sleep
+ * state occurs when it is undergoing a transition to that sleep state, the
+ * transition should be aborted. Moreover, if such an event occurs when the

+ * is being written to and may be delivered to user space right before it is
+ * frozen, so the event will remain only partially processed until the system is
+ * woken up by another event. In particular, it won't cause the transition to
+ * a sleep state to be aborted.
+ *
+ * This difficulty may be overcome if user space uses 'wakeup_count' before

+ * or device is responsible for actually aggregating the frames,
+ * as well as deciding how many and which to aggregate.
*
- * When TX aggregation is started by some subsystem (usually the rate control
- * algorithm would be appropriate) by calling the
- * ieee80211_start_tx_ba_session() function, the driver will be notified via

*
* In response to that, the driver is later required to call the

+ * again right away. Note that it is possible for the aggregation
+ * session to be stopped before the driver has indicated that it
+ * is done setting it up, in which case it must not indicate the
+ * setup completion.
*
- * Similarly, when the aggregation session is stopped by
- * ieee80211_stop_tx_ba_session(), the driver's @ampdu_action function will
- * be called with the action %IEEE80211_AMPDU_TX_STOP. In this case, the
- * call must not fail, and the driver must later call ieee80211_stop_tx_ba_cb()
- * (or ieee80211_stop_tx_ba_cb_irqsafe()).
+ * Also note that, since we also need to wait for a response from

+ * AppArmor policy is based around profiles, which contain the rules a
+ * task is confined by. Every task in the system has a profile attached
+ * to it determined either by matching "unconfined" tasks against the
+ * visible set of profiles or by following a profiles attachment rules.
+ *
+ * Each profile exists in a profile namespace which is a container of
+ * visible profiles. Each namespace contains a special "unconfined" profile,
+ * which doesn't enforce any confinement on a task beyond DAC.
+ *
+ * Namespace and profile names can be written together in either
+ * of two syntaxes.
+ * :namespace:profile - used by kernel interfaces for easy detection
+ * namespace://profile - used by policy
+ *
+ * Profile names can not start with : or @ or ^ and may not contain \0
+ *
+ * Reserved profile names
+ * unconfined - special automatically generated unconfined profile
+ * inherit - special name to indicate profile inheritance
+ * null-XXXX-YYYY - special automatically generated learning profiles
+ *
+ * Namespace names may not start with / or @ and may not contain \0 or :
+ * Reserved namespace names
+ * user-XXXX - user defined profiles
+ *
+ * a // in a profile or namespace name indicates a hierarchical name with the
+ * name before the // being the parent and the name after the child.
+ *
+ * Profile and namespace hierarchies serve two different but similar purposes.
+ * The namespace contains the set of visible profiles that are considered
+ * for attachment. The hierarchy of namespaces allows for virtualizing
+ * the namespace so that for example a chroot can have its own set of profiles
+ * which may define some local user namespaces.
+ * The profile hierarchy severs two distinct purposes,
+ * - it allows for sub profiles or hats, which allows an application to run
+ * subprograms under its own profile with different restriction than it
+ * self, and not have it use the system profile.
+ * eg. if a mail program starts an editor, the policy might make the
+ * restrictions tighter on the editor tighter than the mail program,
+ * and definitely different than general editor restrictions
+ * - it allows for binary hierarchy of profiles, so that execution history
+ * is preserved. This feature isn't exploited by AppArmor reference policy
+ * but is allowed. NOTE: this is currently suboptimal because profile
+ * aliasing is not currently implemented so that a profile for each
+ * level must be defined.
+ * eg. /bin/bash///bin/ls as a name would indicate /bin/ls was started
+ * from /bin/bash
+ *
+ * A profile or namespace name that can contain one or more // separators
+ * is referred to as an hname (hierarchical).
+ * eg. /bin/bash//bin/ls
+ *
+ * An fqname is a name that may contain both namespace and profile hnames.
+ * eg. :ns:/bin/bash//bin/ls
+ *
+ * NOTES:
+ * - locking of profile lists is currently fairly coarse. All profile
+ * lists within a namespace use the namespace lock.
+ * FIXME: move profile lists to using rcu_lists

- * and all entries are retrieved by

- * # grep ^keep_domain /sys/kernel/security/tomoyo/exception_policy
- *
- * In the example above, any process which belongs to
- * "<kernel> /usr/sbin/sshd /bin/bash" domain will remain in that domain,
