+sysfs interface
+---------------
+
+The pktcdvd module (packet writing driver) creates
+these files in the sysfs:
+(<devid> is in format major:minor )
+
+/sys/class/pktcdvd/
+ add (0200) Write a block device id (major:minor)
+ to create a new pktcdvd device and map
+ it to the block device.
+
+ remove (0200) Write the pktcdvd device id (major:minor)
+ to it to remove the pktcdvd device.
+
+ device_map (0444) Shows the device mapping in format:
+ pktcdvd[0-7] <pktdevid> <blkdevid>
+
+/sys/class/pktcdvd/pktcdvd[0-7]/
+ dev (0444) Device id
+ uevent (0200) To send an uevent.
+
+/sys/class/pktcdvd/pktcdvd[0-7]/stat/
+ packets_started (0444) Number of started packets.
+ packets_finished (0444) Number of finished packets.
+
+ kb_written (0444) kBytes written.
+ kb_read (0444) kBytes read.
+ kb_read_gather (0444) kBytes read to fill write packets.
+
+ reset (0200) Write any value to it to reset
+ pktcdvd device statistic values, like
+ bytes read/written.
+
+/sys/class/pktcdvd/pktcdvd[0-7]/write_queue/
+ size (0444) Contains the size of the bio write
+ queue.
+
+ congestion_off (0644) If bio write queue size is below
+ this mark, accept new bio requests
+ from the block layer.
+
+ congestion_on (0644) If bio write queue size is higher
+ as this mark, do no longer accept
+ bio write requests from the block
+ layer and wait till the pktcdvd
+ device has processed enough bio's
+ so that bio write queue size is
+ below congestion off mark.
+ A value of <= 0 disables congestion
+ control.
+
+
+Example:
+--------
+To use the pktcdvd sysfs interface directly, you can do:
+
+# create a new pktcdvd device mapped to /dev/hdc
+echo "22:0" >/sys/class/pktcdvd/add
+cat /sys/class/pktcdvd/device_map
+# assuming device pktcdvd0 was created, look at stat's
+cat /sys/class/pktcdvd/pktcdvd0/stat/kb_written
+# print the device id of the mapped block device
+fgrep pktcdvd0 /sys/class/pktcdvd/device_map
+# remove device, using pktcdvd0 device id 253:0
+echo "253:0" >/sys/class/pktcdvd/remove

25-line terminal screens here), you have more empty lines to put
comments on.
+ 3.1: Spaces
+
+Linux kernel style for use of spaces depends (mostly) on
+function-versus-keyword usage. Use a space after (most) keywords. The
+notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
+somewhat like functions (and are usually used with parentheses in Linux,
+although they are not required in the language, as in: "sizeof info" after
+"struct fileinfo info;" is declared).
+
+So use a space after these keywords:
+ if, switch, case, for, do, while
+but not with sizeof, typeof, alignof, or __attribute__. E.g.,
+ s = sizeof(struct file);
+
+Do not add spaces around (inside) parenthesized expressions. This example is
+*bad*:
+
+ s = sizeof( struct file );
+
+When declaring pointer data or a function that returns a pointer type, the
+preferred use of '*' is adjacent to the data name or function name and not
+adjacent to the type name. Examples:
+
+ char *linux_banner;
+ unsigned long long memparse(char *ptr, char **retptr);
+ char *match_strdup(substring_t *s);
+
+Use one space around (on each side of) most binary and ternary operators,
+such as any of these:
+
+ = + - < > * / % | & ^ <= >= == != ? :
+
+but no space after unary operators:
+ & * + - ~ ! sizeof typeof alignof __attribute__ defined

+no space before the postfix increment & decrement unary operators:
+ ++ --

+Using the pktcdvd sysfs interface
+---------------------------------
+
+Since Linux 2.6.19, the pktcdvd module has a sysfs interface
+and can be controlled by it. For example the "pktcdvd" tool uses
+this interface. (see http://people.freenet.de/BalaGi#pktcdvd )
+
+"pktcdvd" works similar to "pktsetup", e.g.:
+
+ # pktcdvd -a dev_name /dev/hdc
+ # mkudffs /dev/pktcdvd/dev_name
+ # mount -t udf -o rw,noatime /dev/pktcdvd/dev_name /dvdram

+ # umount /dvdram
+ # pktcdvd -r dev_name
+
+

+Fault injection capabilities infrastructure
+===========================================
+
+See also drivers/md/faulty.c and "every_nth" module option for scsi_debug.
+
+
+Available fault injection capabilities
+--------------------------------------
+
+o failslab
+
+ injects slab allocation failures. (kmalloc(), kmem_cache_alloc(), ...)
+
+o fail_page_alloc
+
+ injects page allocation failures. (alloc_pages(), get_free_pages(), ...)
+
+o fail_make_request
+
+ injects disk IO errors on devices permitted by setting
+ /sys/block/<device>/make-it-fail or
+ /sys/block/<device>/<partition>/make-it-fail. (generic_make_request())
+
+Configure fault-injection capabilities behavior
+-----------------------------------------------
+
+o debugfs entries
+
+fault-inject-debugfs kernel module provides some debugfs entries for runtime
+configuration of fault-injection capabilities.
+
+- /debug/fail*/probability:
+
+ likelihood of failure injection, in percent.
+ Format: <percent>
+
+ Note that one-failure-per-hundred is a very high error rate
+ for some testcases. Consider setting probability=100 and configure
+ /debug/fail*/interval for such testcases.
+
+- /debug/fail*/interval:
+
+ specifies the interval between failures, for calls to
+ should_fail() that pass all the other tests.
+
+ Note that if you enable this, by setting interval>1, you will
+ probably want to set probability=100.
+
+- /debug/fail*/times:
+
+ specifies how many times failures may happen at most.
+ A value of -1 means "no limit".
+
+- /debug/fail*/space:
+
+ specifies an initial resource "budget", decremented by "size"
+ on each call to should_fail(,size). Failure injection is
+ suppressed until "space" reaches zero.
+
+- /debug/fail*/verbose
+
+ Format: { 0 | 1 | 2 }
+ specifies the verbosity of the messages when failure is
+ injected. '0' means no messages; '1' will print only a single
+ log line per failure; '2' will print a call trace too -- useful
+ to debug the problems revealed by fault injection.
+
+- /debug/fail*/task-filter:
+
+ Format: { 'Y' | 'N' }
+ A value of 'N' disables filtering by process (default).
+ Any positive value limits failures to only processes indicated by
+ /proc/<pid>/make-it-fail==1.
+
+- /debug/fail*/require-start:
+- /debug/fail*/require-end:
+- /debug/fail*/reject-start:
+- /debug/fail*/reject-end:
+
+ specifies the range of virtual addresses tested during
+ stacktrace walking. Failure is injected only if some caller
+ in the walked stacktrace lies within the required range, and
+ none lies within the rejected range.
+ Default required range is [0,ULONG_MAX) (whole of virtual address space).
+ Default rejected range is [0,0).
+
+- /debug/fail*/stacktrace-depth:
+
+ specifies the maximum stacktrace depth walked during search
+ for a caller within [require-start,require-end) OR
+ [reject-start,reject-end).
+
+- /debug/fail_page_alloc/ignore-gfp-highmem:
+
+ Format: { 'Y' | 'N' }
+ default is 'N', setting it to 'Y' won't inject failures into
+ highmem/user allocations.
+
+- /debug/failslab/ignore-gfp-wait:
+- /debug/fail_page_alloc/ignore-gfp-wait:
+
+ Format: { 'Y' | 'N' }
+ default is 'N', setting it to 'Y' will inject failures
+ only into non-sleep allocations (GFP_ATOMIC allocations).
+
+o Boot option
+
+In order to inject faults while debugfs is not available (early boot time),
+use the boot option:
+
+ failslab=
+ fail_page_alloc=
+ fail_make_request=<interval>,<probability>,<space>,<times>
+
+How to add new fault injection capability
+-----------------------------------------
+
+o #include <linux/fault-inject.h>
+
+o define the fault attributes
+
+ DECLARE_FAULT_INJECTION(name);
+
+ Please see the definition of struct fault_attr in fault-inject.h
+ for details.
+
+o provide a way to configure fault attributes
+
+- boot option
+
+ If you need to enable the fault injection capability from boot time, you can
+ provide boot option to configure it. There is a helper function for it:
+
+ setup_fault_attr(attr, str);
+
+- debugfs entries
+
+ failslab, fail_page_alloc, and fail_make_request use this way.
+ Helper functions:
+
+ init_fault_attr_entries(entries, attr, name);
+ void cleanup_fault_attr_entries(entries);
+
+- module parameters
+
+ If the scope of the fault injection capability is limited to a
+ single kernel module, it is better to provide module parameters to
+ configure the fault attributes.
+
+o add a hook to insert failures
+
+ Upon should_fail() returning true, client code should inject a failure.
+
+ should_fail(attr, size);

+Fan Control
+-----------
+
+Both PWM (pulse-width modulation) and DC fan speed control methods are
+supported. The right one to use depends on external circuitry on the

+properly. The driver will report the method, but won't let you change

+
+When the PWM method is used, you can select the operating frequency,

+fan model. As a rule of thumb, lower frequencies seem to give better
+control, but may generate annoying high-pitch noise. Fintek recommends
+not going below 1 kHz, as the fan tachometers get confused by lower
+frequencies as well.
+
+When the DC method is used, Fintek recommends not going below 5 V, which
+corresponds to a pwm value of 106 for the driver. The driver doesn't
+enforce this limit though.
+
+Three different fan control modes are supported:
+
+* Manual mode
+ You ask for a specific PWM duty cycle or DC voltage.
+
+* Fan speed mode
+ You ask for a specific fan speed. This mode assumes that pwm1
+ corresponds to fan1, pwm2 to fan2 and pwm3 to fan3.
+
+* Temperature mode
+ You define 3 temperature/fan speed trip points, and the fan speed is
+ adjusted depending on the measured temperature, using interpolation.

+ 0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for Winbond W83793G/W83793R chips.
+
+* Exported features
+ This driver exports 10 voltage sensors, up to 12 fan tachometer inputs,
+ 6 remote temperatures, up to 8 sets of PWM fan controls, SmartFan
+ (automatic fan speed control) on all temperature/PWM combinations, 2
+ sets of 6-pin CPU VID input.
+
+* Sensor resolutions
+ If your motherboard maker used the reference design, the resolution of
+ voltage0-2 is 2mV, resolution of voltage3/4/5 is 16mV, 8mV for voltage6,
+ 24mV for voltage7/8. Temp1-4 have a 0.25 degree Celsius resolution,
+ temp5-6 have a 1 degree Celsiis resolution.
+
+* Temperature sensor types
+ Temp1-4 have 2 possible types. It can be read from (and written to)
+ temp[1-4]_type.
+ - If the value is 3, it starts monitoring using a remote termal diode
+ (default).
+ - If the value is 6, it starts monitoring using the temperature sensor
+ in Intel CPU and get result by PECI.
+ Temp5-6 can be connected to external thermistors (value of
+ temp[5-6]_type is 4).
+
+* Alarm mechanism
+ For voltage sensors, an alarm triggers if the measured value is below
+ the low voltage limit or over the high voltage limit.
+ For temperature sensors, an alarm triggers if the measured value goes
+ above the high temperature limit, and wears off only after the measured
+ value drops below the hysteresis value.
+ For fan sensors, an alarm triggers if the measured value is below the
+ low speed limit.
+
+* SmartFan/PWM control
+ If you want to set a pwm fan to manual mode, you just need to make sure it
+ is not controlled by any temp channel, for example, you want to set fan1
+ to manual mode, you need to check the value of temp[1-6]_fan_map, make
+ sure bit 0 is cleared in the 6 values. And then set the pwm1 value to
+ control the fan.
+
+ Each temperature channel can control all the 8 PWM outputs (by setting the
+ corresponding bit in tempX_fan_map), you can set the temperature channel
+ mode using temp[1-6]_pwm_enable, 2 is Thermal Cruise mode and 3
+ is the SmartFanII mode. Temperature channels will try to speed up or
+ slow down all controlled fans, this means one fan can receive different
+ PWM value requests from different temperature channels, but the chip
+ will always pick the safest (max) PWM value for each fan.
+
+ In Thermal Cruise mode, the chip attempts to keep the temperature at a
+ predefined value, within a tolerance margin. So if tempX_input >
+ thermal_cruiseX + toleranceX, the chip will increase the PWM value,
+ if tempX_input < thermal_cruiseX - toleranceX, the chip will decrease
+ the PWM value. If the temperature is within the tolerance range, the PWM
+ value is left unchanged.
+
+ SmartFanII works differently, you have to define up to 7 PWM, temperature
+ trip points, defining a PWM/temperature curve which the chip will follow.
+ While not fundamentally different from the Thermal Cruise mode, the
+ implementation is quite different, giving you a finer-grained control.
+
+* Chassis
+ If the case open alarm triggers, it will stay in this state unless cleared
+ by any write to the sysfs file "chassis".
+
+* VID and VRM
+ The VRM version is detected automatically, don't modify the it unless you
+ *do* know the cpu VRM version and it's not properly detected.
+
+
+Notes
+-----
+
+ Only Fan1-5 and PWM1-3 are guaranteed to always exist, other fan inputs and
+ PWM outputs may or may not exist depending on the chip pin configuration.

+
+Building a relocatable kernel is advantageous from the point of view that
+one does not have to build a second kernel for capturing the dump. But

+suitable to his needs.

0. Structure of PCI drivers
~~~~~~~~~~~~~~~~~~~~~~~~~~~
-There exist two kinds of PCI drivers: new-style ones (which leave most of
-probing for devices to the PCI layer and support online insertion and removal
-of devices [thus supporting PCI, hot-pluggable PCI and CardBus in a single
-driver]) and old-style ones which just do all the probing themselves. Unless
-you have a very good reason to do so, please don't use the old way of probing
-in any new code. After the driver finds the devices it wishes to operate
-on (either the old or the new way), it needs to perform the following steps:
+PCI drivers "discover" PCI devices in a system via pci_register_driver().
+Actually, it's the other way around. When the PCI generic code discovers
+a new device, the driver with a matching "description" will be notified.
+Details on this below.
+
+pci_register_driver() leaves most of the probing for devices to
+the PCI layer and supports online insertion/removal of devices [thus
+supporting hot-pluggable PCI, CardBus, and Express-Card in a single driver].
+pci_register_driver() call requires passing in a table of function
+pointers and thus dictates the high level structure of a driver.
+
+Once the driver knows about a PCI device and takes ownership, the
+driver generally needs to perform the following initialization:
Enable the device
- Access device configuration space
- Discover resources (addresses and IRQ numbers) provided by the device
- Allocate these resources
- Communicate with the device
+ Request MMIO/IOP resources
+ Set the DMA mask size (for both coherent and streaming DMA)
+ Allocate and initialize shared control data (pci_allocate_coherent())
+ Access device configuration space (if needed)
+ Register IRQ handler (request_irq())
+ Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+ Enable DMA/processing engines
+
+When done using the device, and perhaps the module needs to be unloaded,
+the driver needs to take the follow steps:
+ Disable the device from generating IRQs
+ Release the IRQ (free_irq())
+ Stop all DMA activity
+ Release DMA buffers (both streaming and coherent)
+ Unregister from other subsystems (e.g. scsi or netdev)
+ Release MMIO/IOP resources
Disable the device
-Most of these topics are covered by the following sections, for the rest
-look at <linux/pci.h>, it's hopefully well commented.
+Most of these topics are covered in the following sections.
+For the rest look at LDD3 or <linux/pci.h> .
If the PCI subsystem is not configured (CONFIG_PCI is not set), most of

-empty or just returning an appropriate error codes to avoid lots of ifdefs

-3. Enabling and disabling devices
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Before you do anything with the device you've found, you need to enable

+3. Device Initialization Steps
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- If you want to use the PCI Memory-Write-Invalidate transaction,
+As noted in the introduction, most PCI drivers need the following steps

+
+ Enable the device
+ Request MMIO/IOP resources
+ Set the DMA mask size (for both coherent and streaming DMA)

+ Access device configuration space (if needed)
+ Register IRQ handler (request_irq())
+ Initialize non-PCI (i.e. LAN/SCSI/etc parts of the chip)
+ Enable DMA/processing engines.
+
+The driver can access PCI config space registers at any time.
+(Well, almost. When running BIST, config space can go away...but
+that will just result in a PCI Bus Master Abort and config reads
+will return garbage).
+
+
+3.1 Enable the PCI device
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Before touching any device registers, the driver needs to enable
+the PCI device by calling pci_enable_device(). This will:
+ o wake up the device if it was in suspended state,
+ o allocate I/O and memory regions of the device (if BIOS did not),
+ o allocate an IRQ (if BIOS did not).
+
+NOTE: pci_enable_device() can fail! Check the return value.
+NOTE2: Also see pci_enable_device_bars() below. Drivers can
+ attempt to enable only a subset of BARs they need.
+
+[ OS BUG: we don't check resource allocations before enabling those
+ resources. The sequence would make more sense if we called
+ pci_request_resources() before calling pci_enable_device().

+in the PCI_COMMAND register. It also fixes the latency timer value if

+3.2 Request MMIO/IOP resources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Memory (MMIO), and I/O port addresses should NOT be read directly
+from the PCI device config space. Use the values in the pci_dev structure
+as the PCI "bus address" might have been remapped to a "host physical"
+address by the arch/chip-set specific kernel support.
+
+See Documentation/IO-mapping.txt for how to access device registers
+or device memory.
+
+The device driver needs to call pci_request_region() to verify
+no other device is already using the same address resource.
+Conversely, drivers should call pci_release_region() AFTER
calling pci_disable_device().
+The idea is to prevent two devices colliding on the same address range.
-4. How to access PCI config space
+[ See OS BUG comment above. Currently (2.6.19), The driver can only
+ determine MMIO and IO Port resource availability _after_ calling
+ pci_enable_device(). ]
+
+Generic flavors of pci_request_region() are request_mem_region()
+(for MMIO ranges) and request_region() (for IO Port ranges).
+Use these for address resources that are not described by "normal" PCI
+BARs.
+
+Also see pci_request_selected_regions() below.
+
+
+3.3 Set the DMA mask size
+~~~~~~~~~~~~~~~~~~~~~~~~~
+[ If anything below doesn't make sense, please refer to
+ Documentation/DMA-API.txt. This section is just a reminder that
+ drivers need to indicate DMA capabilities of the device and is not
+ an authoritative source for DMA interfaces. ]
+
+While all drivers should explicitly indicate the DMA capability
+(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
+32-bit bus master capability for streaming data need the driver
+to "register" this capability by calling pci_set_dma_mask() with
+appropriate parameters. In general this allows more efficient DMA
+on systems where System RAM exists above 4G _physical_ address.
+
+Drivers for all PCI-X and PCIe compliant devices must call
+pci_set_dma_mask() as they are 64-bit DMA devices.
+
+Similarly, drivers must also "register" this capability if the device
+can directly address "consistent memory" in System RAM above 4G physical
+address by calling pci_set_consistent_dma_mask().
+Again, this includes drivers for all PCI-X and PCIe compliant devices.
+Many 64-bit "PCI" devices (before PCI-X) and some PCI-X devices are
+64-bit DMA capable for payload ("streaming") data but not control
+("consistent") data.
+
+
+3.4 Setup shared control data
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Once the DMA masks are set, the driver can allocate "consistent" (a.k.a. shared)
+memory. See Documentation/DMA-API.txt for a full description of
+the DMA APIs. This section is just a reminder that it needs to be done
+before enabling DMA on the device.
+
+
+3.5 Initialize device registers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers will need specific "capability" fields programmed
+or other "vendor specific" register initialized or reset.
+E.g. clearing pending interrupts.
+
+
+3.6 Register IRQ handler
+~~~~~~~~~~~~~~~~~~~~~~~~
+While calling request_irq() is the the last step described here,
+this is often just another intermediate step to initialize a device.
+This step can often be deferred until the device is opened for use.
+
+All interrupt handlers for IRQ lines should be registered with IRQF_SHARED
+and use the devid to map IRQs to devices (remember that all PCI IRQ lines
+can be shared).
+
+request_irq() will associate an interrupt handler and device handle
+with an interrupt number. Historically interrupt numbers represent
+IRQ lines which run from the PCI device to the Interrupt controller.
+With MSI and MSI-X (more below) the interrupt number is a CPU "vector".
+
+request_irq() also enables the interrupt. Make sure the device is
+quiesced and does not have any interrupts pending before registering
+the interrupt handler.
+
+MSI and MSI-X are PCI capabilities. Both are "Message Signaled Interrupts"
+which deliver interrupts to the CPU via a DMA write to a Local APIC.
+The fundamental difference between MSI and MSI-X is how multiple
+"vectors" get allocated. MSI requires contiguous blocks of vectors
+while MSI-X can allocate several individual ones.
+
+MSI capability can be enabled by calling pci_enable_msi() or
+pci_enable_msix() before calling request_irq(). This causes
+the PCI support to program CPU vector data into the PCI device
+capability registers.
+
+If your PCI device supports both, try to enable MSI-X first.
+Only one can be enabled at a time. Many architectures, chip-sets,
+or BIOSes do NOT support MSI or MSI-X and the call to pci_enable_msi/msix
+will fail. This is important to note since many drivers have
+two (or more) interrupt handlers: one for MSI/MSI-X and another for IRQs.
+They choose which handler to register with request_irq() based on the
+return value from pci_enable_msi/msix().
+
+There are (at least) two really good reasons for using MSI:
+1) MSI is an exclusive interrupt vector by definition.
+ This means the interrupt handler doesn't have to verify
+ its device caused the interrupt.
+
+2) MSI avoids DMA/IRQ race conditions. DMA to host memory is guaranteed
+ to be visible to the host CPU(s) when the MSI is delivered. This
+ is important for both data coherency and avoiding stale control data.
+ This guarantee allows the driver to omit MMIO reads to flush
+ the DMA stream.
+
+See drivers/infiniband/hw/mthca/ or drivers/net/tg3.c for examples
+of MSI/MSI-X usage.
+
+
+
+4. PCI device shutdown
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When a PCI device driver is being unloaded, most of the following
+steps need to be performed:
+
+ Disable the device from generating IRQs
+ Release the IRQ (free_irq())
+ Stop all DMA activity
+ Release DMA buffers (both streaming and consistent)
+ Unregister from other subsystems (e.g. scsi or netdev)
+ Disable device from responding to MMIO/IO Port addresses
+ Release MMIO/IO Port resource(s)
+
+
+4.1 Stop IRQs on the device
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+How to do this is chip/device specific. If it's not done, it opens
+the possibility of a "screaming interrupt" if (and only if)
+the IRQ is shared with another device.
+
+When the shared IRQ handler is "unhooked", the remaining devices
+using the same IRQ line will still need the IRQ enabled. Thus if the
+"unhooked" device asserts IRQ line, the system will respond assuming
+it was one of the remaining devices asserted the IRQ line. Since none
+of the other devices will handle the IRQ, the system will "hang" until
+it decides the IRQ isn't going to get handled and masks the IRQ (100,000
+iterations later). Once the shared IRQ is masked, the remaining devices
+will stop functioning properly. Not a nice situation.
+
+This is another reason to use MSI or MSI-X if it's available.
+MSI and MSI-X are defined to be exclusive interrupts and thus
+are not susceptible to the "screaming interrupt" problem.
+
+
+4.2 Release the IRQ
+~~~~~~~~~~~~~~~~~~~
+Once the device is quiesced (no more IRQs), one can call free_irq().
+This function will return control once any pending IRQs are handled,
+"unhook" the drivers IRQ handler from that IRQ, and finally release
+the IRQ if no one else is using it.
+
+
+4.3 Stop all DMA activity
+~~~~~~~~~~~~~~~~~~~~~~~~~
+It's extremely important to stop all DMA operations BEFORE attempting
+to deallocate DMA control data. Failure to do so can result in memory
+corruption, hangs, and on some chip-sets a hard crash.
+
+Stopping DMA after stopping the IRQs can avoid races where the
+IRQ handler might restart DMA engines.
+
+While this step sounds obvious and trivial, several "mature" drivers
+didn't get this step right in the past.
+
+
+4.4 Release DMA buffers
+~~~~~~~~~~~~~~~~~~~~~~~
+Once DMA is stopped, clean up streaming DMA first.
+I.e. unmap data buffers and return buffers to "upstream"
+owners if there is one.
+
+Then clean up "consistent" buffers which contain the control data.
+
+See Documentation/DMA-API.txt for details on unmapping interfaces.
+
+
+4.5 Unregister from other subsystems
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most low level PCI device drivers support some other subsystem
+like USB, ALSA, SCSI, NetDev, Infiniband, etc. Make sure your
+driver isn't losing resources from that other subsystem.
+If this happens, typically the symptom is an Oops (panic) when
+the subsystem attempts to call into a driver that has been unloaded.
+
+
+4.6 Disable Device from responding to MMIO/IO Port addresses
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+io_unmap() MMIO or IO Port resources and then call pci_disable_device().
+This is the symmetric opposite of pci_enable_device().
+Do not access device registers after calling pci_disable_device().
+
+
+4.7 Release MMIO/IO Port Resource(s)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Call pci_release_region() to mark the MMIO or IO Port range as available.
+Failure to do so usually results in the inability to reload the driver.

+
+
+
+10. pci_enable_device_bars() and Legacy I/O Port space
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Large servers may not be able to provide I/O port resources to all PCI
+devices. I/O Port space is only 64KB on Intel Architecture[1] and is
+likely also fragmented since the I/O base register of PCI-to-PCI
+bridge will usually be aligned to a 4KB boundary[2]. On such systems,
+pci_enable_device() and pci_request_region() will fail when
+attempting to enable I/O Port regions that don't have I/O Port
+resources assigned.
+
+Fortunately, many PCI devices which request I/O Port resources also
+provide access to the same registers via MMIO BARs. These devices can
+be handled without using I/O port space and the drivers typically
+offer a CONFIG_ option to only use MMIO regions
+(e.g. CONFIG_TULIP_MMIO). PCI devices typically provide I/O port
+interface for legacy OSes and will work when I/O port resources are not
+assigned. The "PCI Local Bus Specification Revision 3.0" discusses
+this on p.44, "IMPLEMENTATION NOTE".
+
+If your PCI device driver doesn't need I/O port resources assigned to
+I/O Port BARs, you should use pci_enable_device_bars() instead of
+pci_enable_device() in order not to enable I/O port regions for the
+corresponding devices. In addition, you should use
+pci_request_selected_regions() and pci_release_selected_regions()
+instead of pci_request_regions()/pci_release_regions() in order not to
+request/release I/O port regions for the corresponding devices.
+
+[1] Some systems support 64KB I/O port space per PCI segment.
+[2] Some PCI-to-PCI bridges support optional 1KB aligned I/O base.
+
+
+
+11. MMIO Space and "Write Posting"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Converting a driver from using I/O Port space to using MMIO space
+often requires some additional changes. Specifically, "write posting"
+needs to be handled. Many drivers (e.g. tg3, acenic, sym53c8xx_2)
+already do this. I/O Port space guarantees write transactions reach the PCI
+device before the CPU can continue. Writes to MMIO space allow the CPU
+to continue before the transaction reaches the PCI device. HW weenies
+call this "Write Posting" because the write completion is "posted" to
+the CPU before the transaction has reached its destination.
+
+Thus, timing sensitive code should add readl() where the CPU is
+expected to wait before doing other work. The classic "bit banging"
+sequence works fine for I/O Port space:
+
+ for (i = 8; --i; val >>= 1) {
+ outb(val & 1, ioport_reg); /* write bit */
+ udelay(10);
+ }
+
+The same sequence for MMIO space should be:
+
+ for (i = 8; --i; val >>= 1) {
+ writeb(val & 1, mmio_reg); /* write bit */
+ readb(safe_mmio_reg); /* flush posted write */
+ udelay(10);
+ }
+
+It is important that "safe_mmio_reg" not have any side effects that
+interferes with the correct operation of the device.
+
+Another case to watch out for is when resetting a PCI device. Use PCI
+Configuration space reads to flush the writel(). This will gracefully
+handle the PCI master abort on all platforms if the PCI device is
+expected to not respond to a readl(). Most x86 platforms will allow
+MMIO reads to master abort (a.k.a. "Soft Fail") and return garbage
+(e.g. ~0). But many RISC platforms will crash (a.k.a."Hard Fail").

In this example, device 0815 is accessed via subchannel 0 in subchannel set 0,
device 4711 via subchannel 1 in subchannel set 0, and subchannel 2 is a non-I/O
subchannel. Device 1234 is accessed via subchannel 0 in subchannel set 1.
+The subchannel named 'defunct' does not represent any real subchannel on the
+system; it is a pseudo subchannel where disconnnected ccw devices are moved to
+if they are displaced by another ccw device becoming operational on their
+former subchannel. The ccw devices will be moved again to a proper subchannel
+if they become operational again on that subchannel.
+
You should address a ccw device via its bus id (e.g. 0.0.4711); the device can
be found under bus/ccw/devices/.

this function. In such a situation defer it.
+Driver Access
+
+Line discipline methods can call the following methods of the underlying
+hardware driver through the function pointers within the tty->driver
+structure:
+
+write() Write a block of characters to the tty device.
+ Returns the number of characters accepted.
+
+put_char() Queues a character for writing to the tty device.
+ If there is no room in the queue, the character is
+ ignored.
+
+flush_chars() (Optional) If defined, must be called after
+ queueing characters with put_char() in order to
+ start transmission.
+
+write_room() Returns the numbers of characters the tty driver
+ will accept for queueing to be written.
+
+ioctl() Invoke device specific ioctl.
+ Expects data pointers to refer to userspace.
+ Returns ENOIOCTLCMD for unrecognized ioctl numbers.
+
+set_termios() Notify the tty driver that the device's termios
+ settings have changed. New settings are in
+ tty->termios. Previous settings should be passed in
+ the "old" argument.
+
+throttle() Notify the tty driver that input buffers for the
+ line discipline are close to full, and it should
+ somehow signal that no more characters should be
+ sent to the tty.
+
+unthrottle() Notify the tty driver that characters can now be
+ sent to the tty without fear of overrunning the
+ input buffers of the line disciplines.
+
+stop() Ask the tty driver to stop outputting characters
+ to the tty device.
+
+start() Ask the tty driver to resume sending characters
+ to the tty device.
+
+hangup() Ask the tty driver to hang up the tty device.
+
+break_ctl() (Optional) Ask the tty driver to turn on or off
+ BREAK status on the RS-232 port. If state is -1,
+ then the BREAK status should be turned on; if
+ state is 0, then BREAK should be turned off.
+ If this routine is not implemented, use ioctls
+ TIOCSBRK / TIOCCBRK instead.
+
+wait_until_sent() Waits until the device has written out all of the
+ characters in its transmitter FIFO.
+
+send_xchar() Send a high-priority XON/XOFF character to the device.
+
+
+Flags
+
+Line discipline methods have access to tty->flags field containing the
+following interesting flags:
+
+TTY_THROTTLED Driver input is throttled. The ldisc should call
+ tty->driver->unthrottle() in order to resume
+ reception when it is ready to process more data.
+
+TTY_DO_WRITE_WAKEUP If set, causes the driver to call the ldisc's
+ write_wakeup() method in order to resume
+ transmission when it can accept more data
+ to transmit.
+
+TTY_IO_ERROR If set, causes all subsequent userspace read/write
+ calls on the tty to fail, returning -EIO.
+
+TTY_OTHER_CLOSED Device is a pty and the other side has closed.
+
+TTY_NO_WRITE_SPLIT Prevent driver from splitting up writes into
+ smaller chunks.
+
+

+"cafe_ccic" is a driver for the Marvell 88ALP01 "cafe" CMOS camera
+controller. This is the controller found in first-generation OLPC systems,
+and this driver was written with support from the OLPC project.
+
+Current status: the core driver works. It can generate data in YUV422,
+RGB565, and RGB444 formats. (Anybody looking at the code will see RGB32 as
+well, but that is a debugging aid which will be removed shortly). VGA and
+QVGA modes work; CIF is there but the colors remain funky. Only the OV7670
+sensor is known to work with this controller at this time.
+
+To try it out: either of these commands will work:
+
+ mplayer tv:// -tv driver=v4l2:width=640:height=480 -nosound
+ mplayer tv:// -tv driver=v4l2:width=640:height=480:outfmt=bgr16 -nosound
+
+The "xawtv" utility also works; gqcam does not, for unknown reasons.
+
+There are a few load-time options, most of which can be changed after
+loading via sysfs as well:
+
+ - alloc_bufs_at_load: Normally, the driver will not allocate any DMA
+ buffers until the time comes to transfer data. If this option is set,
+ then worst-case-sized buffers will be allocated at module load time.
+ This option nails down the memory for the life of the module, but
+ perhaps decreases the chances of an allocation failure later on.
+
+ - dma_buf_size: The size of DMA buffers to allocate. Note that this
+ option is only consulted for load-time allocation; when buffers are
+ allocated at run time, they will be sized appropriately for the current
+ camera settings.
+
+ - n_dma_bufs: The controller can cycle through either two or three DMA
+ buffers. Normally, the driver tries to use three buffers; on faster
+ systems, however, it will work well with only two.
+
+ - min_buffers: The minimum number of streaming I/O buffers that the driver
+ will consent to work with. Default is one, but, on slower systems,
+ better behavior with mplayer can be achieved by setting to a higher
+ value (like six).
+
+ - max_buffers: The maximum number of streaming I/O buffers; default is
+ ten. That number was carefully picked out of a hat and should not be
+ assumed to actually mean much of anything.
+
+ - flip: If this boolean parameter is set, the sensor will be instructed to
+ invert the video image. Whether it makes sense is determined by how
+ your particular camera is mounted.
+
+Work is ongoing with this driver, stay tuned.

-Driver for Trust Computer Products Framegrabber, version 0.6.1
------- --- ----- -------- -------- ------------ ------- - - -
-
-- ZORAN ------------------------------------------------------
- Author: Pauline Middelink <middelin@polyware.nl>
- Date: 18 September 1999
-Version: 0.6.1
-
-- Description ------------------------------------------------
-
-Video4Linux compatible driver for an unknown brand framegrabber
-(Sold in the Netherlands by TRUST Computer Products) and various
-other zoran zr36120 based framegrabbers.
-
-The card contains a ZR36120 Multimedia PCI Interface and a Philips
-SAA7110 Onechip Frontend videodecoder. There is also an DSP of
-which I have forgotten the number, since i will never get that thing
-to work without specs from the vendor itself.
-
-The SAA711x are capable of processing 6 different video inputs,
-CVBS1..6 and Y1+C1, Y2+C2, Y3+C3. All in 50/60Hz, NTSC, PAL or
-SECAM and delivering a YUV datastream. On my card the input
-'CVBS-0' corresponds to channel CVBS2 and 'S-Video' to Y2+C2.
-
-I have some reports of other cards working with the mentioned
-chip sets. For a list of other working cards please have a look
-at the cards named in the tvcards struct in the beginning of
-zr36120.c
-
-After some testing, I discovered that the carddesigner messed up
-on the I2C interface. The Zoran chip includes 2 lines SDA and SCL
-which (s)he connected reversely. So we have to clock on the SDA
-and r/w data on the SCL pin. Life is fun... Each cardtype now has
-a bit which signifies if you have a card with the same deficiency.
-
-Oh, for the completeness of this story I must mention that my
-card delivers the VSYNC pulse of the SAA chip to GIRQ1, not
-GIRQ0 as some other cards have. This is also incorporated in
-the driver be clearing/setting the 'useirq1' bit in the tvcard
-description.
-
-Another problems of continuous capturing data with a Zoran chip
-is something nasty inside the chip. It effectively halves the
-fps we ought to get... Here is the scenario: capturing frames
-to memory is done in the so-called snapshot mode. In this mode
-the Zoran stops after capturing a frame worth of data and wait
-till the application set GRAB bit to indicate readiness for the
-next frame. After detecting a set bit, the chip neatly waits
-till the start of a frame, captures it and it goes back to off.
-Smart ppl will notice the problem here. Its the waiting on the
-_next_ frame each time we set the GRAB bit... Oh well, 12,5 fps
-is still plenty fast for me.
--- update 28/7/1999 --
-Don't believe a word I just said... Proof is the output
-of `streamer -t 300 -r 25 -f avi15 -o /dev/null`

- syncer: done
- writer: done
-(note the /dev/null is prudent here, my system is not able to
- grab /and/ write 25 fps to a file... gifts welcome :) )
-The technical reasoning follows: The zoran completed the last
-frame, the VSYNC goes low, and GRAB is cleared. The interrupt
-routine starts to work since its VSYNC driven, and again
-activates the GRAB bit. A few ms later the VSYNC (re-)rises and
-the zoran starts to work on a new and freshly broadcasted frame....
-
-For pointers I used the specs of both chips. Below are the URLs:
- http://www.zoran.com/ftp/download/devices/pci/ZR36120/36120data.pdf
- http://www-us.semiconductor.philips.com/acrobat/datasheets/SAA_7110_A_1.pdf
-Some alternatives for the Philips SAA 7110 datasheet are:
- http://www.datasheetcatalog.com/datasheets_pdf/S/A/A/7/SAA7110.shtml
- http://www.datasheetarchive.com/search.php?search=SAA7110&sType=part
-
-The documentation has very little on absolute numbers or timings
-needed for the various modes/resolutions, but there are other
-programs you can borrow those from.
-
------- Install --------------------------------------------
-Read the file called TODO. Note its long list of limitations.
-
-Build a kernel with VIDEO4LINUX enabled. Activate the
-BT848 driver; we need this because we have need for the
-other modules (i2c and videodev) it enables.
-
-To install this software, extract it into a suitable directory.
-Examine the makefile and change anything you don't like. Type "make".
-
-After making the modules check if you have the much needed
-/dev/video devices. If not, execute the following 4 lines:
- mknod /dev/video c 81 0
- mknod /dev/video1 c 81 1
- mknod /dev/video2 c 81 2
- mknod /dev/video3 c 81 3
- mknod /dev/video4 c 81 4
-
-After making/checking the devices do:
- modprobe i2c
- modprobe videodev
- modprobe saa7110 (optional)
- modprobe saa7111 (optional)
- modprobe tuner (optional)
- insmod zoran cardtype=<n>
-
-<n> is the cardtype of the card you have. The cardnumber can
-be found in the source of zr36120. Look for tvcards. If your
-card is not there, please try if any other card gives some
-response, and mail me if you got a working tvcard addition.
-
-PS. <TVCard editors behold!)
- Don't forget to set video_input to the number of inputs
- you defined in the video_mux part of the tvcard definition.
- It's a common error to add a channel but not incrementing
- video_input and getting angry with me/v4l/linux/linus :(
-
-You are now ready to test the framegrabber with your favorite
-video4linux compatible tool
-
------- Application ----------------------------------------
-
-This device works with all Video4Linux compatible applications,
-given the limitations in the TODO file.
-
------- API ------------------------------------------------
-
-This uses the V4L interface as of kernel release 2.1.116, and in
-fact has not been tested on any lower version. There are a couple
-of minor differences due to the fact that the amount of data returned
-with each frame varies, and no doubt there are discrepancies due to my
-misunderstanding of the API. I intend to convert this driver to the
-new V4L2 API when it has stabilized more.
-
------- Current state --------------------------------------
-
-The driver is capable of overlaying a video image in screen, and
-even capable of grabbing frames. It uses the BIGPHYSAREA patch
-to allocate lots of large memory blocks when tis patch is
-found in the kernel, but it doesn't need it.
-The consequence is that, when loading the driver as a module,
-the module may tell you it's out of memory, but 'free' says
-otherwise. The reason is simple; the modules wants its memory
-contiguous, not fragmented, and after a long uptime there
-probably isn't a fragment of memory large enough...
-
-The driver uses a double buffering scheme, which should really
-be an n-way buffer, depending on the size of allocated framebuffer
-and the requested grab-size/format.
-This current version also fixes a dead-lock situation during irq
-time, which really, really froze my system... :)
-
-Good luck.

+ This gives the physical address where the kernel is loaded.
+
+ If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
+ bzImage will decompress itself to above physical address and
+ run from there. Otherwise, bzImage will run from the address where
+ it has been loaded by the boot loader and will ignore above physical
+ address.
+
+ In normal kdump cases one does not have to set/change this option
+ as now bzImage can be compiled as a completely relocatable image
+ (CONFIG_RELOCATABLE=y) and be used to load and run from a different
+ address. This option is mainly useful for the folks who don't want
+ to use a bzImage for capturing the crash dump and want to use a
+ vmlinux instead. vmlinux is not relocatable hence a kernel needs
+ to be specifically compiled to run from a specific memory area
+ (normally a reserved region) and this option comes handy.
+
+ So if you are using bzImage for capturing the crash dump, leave
+ the value here unchanged to 0x100000 and set CONFIG_RELOCATABLE=y.
+ Otherwise if you plan to use vmlinux for capturing the crash dump
+ change this value to start of the reserved region (Typically 16MB
+ 0x1000000). In other words, it can be set based on the "X" value as
+ specified in the "crashkernel=YM@XM" command line boot parameter
+ passed to the panic-ed kernel. Typically this parameter is set as
+ crashkernel=64M@16M. Please take a look at
+ Documentation/kdump/kdump.txt for more details about crash dumps.
+
+ Usage of bzImage for capturing the crash dump is recommended as
+ one does not have to build two kernels. Same kernel can be used
+ as production kernel and capture kernel. Above option should have
+ gone away after relocatable bzImage support is introduced. But it
+ is present because there are users out there who continue to use
+ vmlinux for dump capture. This option should go away down the
+ line.
+
+ Don't change this unless you know what you are doing.

+ * EC 0x2f not available if GFAN exists
+ *
+ * IBMACPI_FAN_WR_ACPI_SFAN:
+ * ACPI SFAN method: sets fan level, 0 (stop) to 7 (max)
+ *
+ * EC 0x2f might be available *for reading*, but never for writing.
+ *
+ * IBMACPI_FAN_WR_TPEC:
+ * ThinkPad EC register 0x2f (HFSP): fan control loop mode Supported
+ * on almost all ThinkPads
+ *
+ * Fan speed changes of any sort (including those caused by the
+ * disengaged mode) are usually done slowly by the firmware as the
+ * maximum ammount of fan duty cycle change per second seems to be
+ * limited.
+ *
+ * Reading is not available if GFAN exists.
+ * Writing is not available if SFAN exists.
+ *
+ * Bits
+ * 7 automatic mode engaged;
+ * (default operation mode of the ThinkPad)
+ * fan level is ignored in this mode.
+ * 6 disengage mode (takes precedence over bit 7);
+ * not available on all thinkpads. May disable
+ * the tachometer, and speeds up fan to 100% duty-cycle,
+ * which speeds it up far above the standard RPM
+ * levels. It is not impossible that it could cause
+ * hardware damage.
+ * 5-3 unused in some models. Extra bits for fan level
+ * in others, but still useless as all values above
+ * 7 map to the same speed as level 7 in these models.
+ * 2-0 fan level (0..7 usually)
+ * 0x00 = stop
+ * 0x07 = max (set when temperatures critical)
+ * Some ThinkPads may have other levels, see
+ * IBMACPI_FAN_WR_ACPI_FANS (X31/X40/X41)
+ *
+ * FIRMWARE BUG: on some models, EC 0x2f might not be initialized at
+ * boot. Apparently the EC does not intialize it, so unless ACPI DSDT
+ * does so, its initial value is meaningless (0x07).
+ *
+ * For firmware bugs, refer to:
+ * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * ----
+ *
+ * ThinkPad EC register 0x84 (LSB), 0x85 (MSB):
+ * Main fan tachometer reading (in RPM)
+ *
+ * This register is present on all ThinkPads with a new-style EC, and
+ * it is known not to be present on the A21m/e, and T22, as there is
+ * something else in offset 0x84 according to the ACPI DSDT. Other
+ * ThinkPads from this same time period (and earlier) probably lack the
+ * tachometer as well.
+ *
+ * Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare
+ * was never fixed by IBM to report the EC firmware version string
+ * probably support the tachometer (like the early X models), so
+ * detecting it is quite hard. We need more data to know for sure.
+ *
+ * FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings
+ * might result.
+ *
+ * FIRMWARE BUG: when EC 0x2f bit 6 is set (disengaged mode), this
+ * register is not invalidated in ThinkPads that disable tachometer
+ * readings. Thus, the tachometer readings go stale.
+ *
+ * For firmware bugs, refer to:
+ * http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
+ *
+ * IBMACPI_FAN_WR_ACPI_FANS:
+ * ThinkPad X31, X40, X41. Not available in the X60.
+ *
+ * FANS ACPI handle: takes three arguments: low speed, medium speed,
+ * high speed. ACPI DSDT seems to map these three speeds to levels
+ * as follows: STOP LOW LOW MED MED HIGH HIGH HIGH HIGH
+ * (this map is stored on FAN0..FAN8 as "0,1,1,2,2,3,3,3,3")
+ *
+ * The speeds are stored on handles
+ * (FANA:FAN9), (FANC:FANB), (FANE:FAND).
+ *
+ * There are three default speed sets, acessible as handles:
+ * FS1L,FS1M,FS1H; FS2L,FS2M,FS2H; FS3L,FS3M,FS3H
+ *
+ * ACPI DSDT switches which set is in use depending on various
+ * factors.
+ *
+ * IBMACPI_FAN_WR_TPEC is also available and should be used to
+ * command the fan. The X31/X40/X41 seems to have 8 fan levels,
+ * but the ACPI tables just mention level 7.

+ A human interface device (HID) is a type of computer device that
+ interacts directly with and takes input from humans. The term "HID"
+ most commonly used to refer to the USB-HID specification, but other
+ devices (such as, but not strictly limited to, Bluetooth) are
+ designed using HID specification (this involves certain keyboards,
+ mice, tablets, etc). This option compiles into kernel the generic
+ HID layer code (parser, usages, etc.), which can then be used by
+ transport-specific HID implementation (like USB or Bluetooth).
+
+ For docs and specs, see http://www.usb.org/developers/hidpage/
+
+ If unsure, say Y

+ * x86_emulate_ops:
+ *
+ * These operations represent the instruction emulator's interface to memory.
+ * There are two categories of operation: those that act on ordinary memory
+ * regions (*_std), and those that act on memory regions known to require
+ * special treatment or emulation (*_emulated).
+ *
+ * The emulator assumes that an instruction accesses only one 'emulated memory'
+ * location, that this location is the given linear faulting address (cr2), and
+ * that this is one of the instruction's data operands. Instruction fetches and
+ * stack operations are assumed never to access emulated memory. The emulator
+ * automatically deduces which operand of a string-move operation is accessing
+ * emulated memory, and assumes that the other operand accesses normal memory.
+ *
+ * NOTES:
+ * 1. The emulator isn't very smart about emulated vs. standard memory.
+ * 'Emulated memory' access addresses should be checked for sanity.
+ * 'Normal memory' accesses may fault, and the caller must arrange to
+ * detect and handle reentrancy into the emulator via recursive faults.
+ * Accesses may be unaligned and may cross page boundaries.
+ * 2. If the access fails (cannot emulate, or a standard access faults) then
+ * it is up to the memop to propagate the fault to the guest VM via
+ * some out-of-band mechanism, unknown to the emulator. The memop signals
+ * failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
+ * then immediately bail.
+ * 3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
+ * cmpxchg8b_emulated need support 8-byte accesses.
+ * 4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.

+ * Updates to driver completed by Dwaine P. Garden
+ *
+ *
+ * TODO:
+ * - use submit_urb for all setup packets
+ * - Fix memory settings for nt1004. It is 4 times as big as the
+ * nt1003 memory.
+ * - Add audio on endpoint 3 for nt1004 chip. Seems impossible, needs a codec interface. Which one?
+ * - Clean up the driver.
+ * - optimization for performance.
+ * - Add Videotext capability (VBI). Working on it.....
+ * - Check audio for other devices

* OHCI is the main "non-Intel/VIA" standard for USB 1.1 host controller
* interfaces (though some non-x86 Intel chips use it). It supports
* smarter hardware than UHCI. A download link for the spec available
* through the http://www.usb.org website.
*
- * History:
- *
- * 2004/03/24 LH7A404 support (Durgesh Pattamatta & Marc Singer)
- * 2004/02/04 use generic dma_* functions instead of pci_* (dsaxena@plexity.net)
- * 2003/02/24 show registers in sysfs (Kevin Brosius)
- *
- * 2002/09/03 get rid of ed hashtables, rework periodic scheduling and
- * bandwidth accounting; if debugging, show schedules in driverfs
- * 2002/07/19 fixes to management of ED and schedule state.
- * 2002/06/09 SA-1111 support (Christopher Hoover)
- * 2002/06/01 remember frame when HC won't see EDs any more; use that info
- * to fix urb unlink races caused by interrupt latency assumptions;
- * minor ED field and function naming updates
- * 2002/01/18 package as a patch for 2.5.3; this should match the
- * 2.4.17 kernel modulo some bugs being fixed.
- *
- * 2001/10/18 merge pmac cleanup (Benjamin Herrenschmidt) and bugfixes
- * from post-2.4.5 patches.
- * 2001/09/20 URB_ZERO_PACKET support; hcca_dma portability, OPTi warning
- * 2001/09/07 match PCI PM changes, errnos from Linus' tree
- * 2001/05/05 fork 2.4.5 version into "hcd" framework, cleanup, simplify;
- * pbook pci quirks gone (please fix pbook pci sw!) (db)
- *
- * 2001/04/08 Identify version on module load (gb)
- * 2001/03/24 td/ed hashing to remove bus_to_virt (Steve Longerbeam);
- pci_map_single (db)
- * 2001/03/21 td and dev/ed allocation uses new pci_pool API (db)
- * 2001/03/07 hcca allocation uses pci_alloc_consistent (Steve Longerbeam)
- *
- * 2000/09/26 fixed races in removing the private portion of the urb
- * 2000/09/07 disable bulk and control lists when unlinking the last
- * endpoint descriptor in order to avoid unrecoverable errors on
- * the Lucent chips. (rwc@sgi)
- * 2000/08/29 use bandwidth claiming hooks (thanks Randy!), fix some
- * urb unlink probs, indentation fixes
- * 2000/08/11 various oops fixes mostly affecting iso and cleanup from
- * device unplugs.
- * 2000/06/28 use PCI hotplug framework, for better power management
- * and for Cardbus support (David Brownell)
- * 2000/earlier: fixes for NEC/Lucent chips; suspend/resume handling
- * when the controller loses power; handle UE; cleanup; ...
- *
- * v5.2 1999/12/07 URB 3rd preview,
- * v5.1 1999/11/30 URB 2nd preview, cpia, (usb-scsi)
- * v5.0 1999/11/22 URB Technical preview, Paul Mackerras powerbook susp/resume
- * i386: HUB, Keyboard, Mouse, Printer
- *
- * v4.3 1999/10/27 multiple HCs, bulk_request
- * v4.2 1999/09/05 ISO API alpha, new dev alloc, neg Error-codes
- * v4.1 1999/08/27 Randy Dunlap's - ISO API first impl.

- * The following functions <func> are defined,
- * and apply only to the specified cache (I or D):
- *
- * reset
- * Resets the cache.
- *
- * sync
- * Makes sure any previous cache instructions have been completed;
- * ie. makes sure any previous cache control operations
- * have had full effect and been synchronized to memory.
- * Eg. any invalidate completed [so as not to generate a hit],
- * any writebacks or other pipelined writes written to memory, etc.
- *
- * invalidate_line (single cache line)
- * invalidate_region (specified memory range)
- * invalidate_all (entire cache)
- * Invalidates all cache entries that cache
- * data from the specified memory range.
- * NOTE: locked entries are not invalidated.
- *
- * writeback_line (single cache line)
- * writeback_region (specified memory range)
- * writeback_all (entire cache)
- * Writes back to memory all dirty cache entries
- * that cache data from the specified memory range,
- * and marks these entries as clean.
- * NOTE: on some future implementations, this might
- * also invalidate.
- * NOTE: locked entries are written back, but never invalidated.
- * NOTE: instruction caches never implement writeback.
- *
- * writeback_inv_line (single cache line)
- * writeback_inv_region (specified memory range)
- * writeback_inv_all (entire cache)
- * Writes back to memory all dirty cache entries
- * that cache data from the specified memory range,
- * and invalidates these entries (including all clean
- * cache entries that cache data from that range).
- * NOTE: locked entries are written back but not invalidated.
- * NOTE: instruction caches never implement writeback.
- *
- * lock_line (single cache line)
- * lock_region (specified memory range)
- * Prefetch and lock the specified memory range into cache.
- * NOTE: if any part of the specified memory range cannot
- * be locked, a ??? exception occurs. These macros don't
- * do anything special (yet anyway) to handle this situation.
- *
- * unlock_line (single cache line)
- * unlock_region (specified memory range)

- * in the current Xtensa core implementation:
- * cache size: 1024 bytes minimum
- * line size: 16 - 64 bytes
- * way count: 1 - 4
- *
- * Minimum entries per way (ie. per associativity) = 1024 / 64 / 4 = 4
- * Hence the assumption that each loop can execute four cache instructions.
- *
- * Correspondingly, the offset range of instructions is assumed able to cover
- * four lines, ie. offsets {0,1,2,3} * line_size are assumed valid for
- * both hit and indexed cache instructions. Ie. these offsets are all
- * valid: 0, 16, 32, 48, 64, 96, 128, 192 (for line sizes 16, 32, 64).
- * This is true of all original cache instructions
- * (dhi, ihi, dhwb, dhwbi, dii, iii) which have offsets
- * of 0 to 1020 in multiples of 4 (ie. 8 bits shifted by 2).
- * This is also true of subsequent cache instructions
- * (dhu, ihu, diu, iiu, diwb, diwbi, dpfl, ipfl) which have offsets
- * of 0 to 240 in multiples of 16 (ie. 4 bits shifted by 4).

- * Works even when changing one's own code's attributes.

- ----------------------------------------------------------------------*/
-
-/*
- * General notes on MMU parameters.
- *
- * Terminology:
- * ASID = address-space ID (acts as an "extension" of virtual addresses)
- * VPN = virtual page number
- * PPN = physical page number
- * CA = encoded cache attribute (access modes)
- * TLB = translation look-aside buffer (term is stretched somewhat here)
- * I = instruction (fetch accesses)
- * D = data (load and store accesses)
- * way = each TLB (ITLB and DTLB) consists of a number of "ways"
- * that simultaneously match the virtual address of an access;
- * a TLB successfully translates a virtual address if exactly
- * one way matches the vaddr; if none match, it is a miss;
- * if multiple match, one gets a "multihit" exception;
- * each way can be independently configured in terms of number of
- * entries, page sizes, which fields are writable or constant, etc.
- * set = group of contiguous ways with exactly identical parameters
- * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
- * from the page table and storing it in one of the auto-refill ways;
- * if this PTE load also misses, a miss exception is posted for s/w.
- * min-wired = a "min-wired" way can be used to map a single (minimum-sized)
- * page arbitrarily under program control; it has a single entry,
- * is non-auto-refill (some other way(s) must be auto-refill),
- * all its fields (VPN, PPN, ASID, CA) are all writable, and it
- * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
- * restriction is that this be the only page size it supports).
- *
- * TLB way entries are virtually indexed.
- * TLB ways that support multiple page sizes:
- * - must have all writable VPN and PPN fields;
- * - can only use one page size at any given time (eg. setup at startup),
- * selected by the respective ITLBCFG or DTLBCFG special register,
- * whose bits n*4+3 .. n*4 index the list of page sizes for way n
- * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
- * this list may be sparse for auto-refill ways because auto-refill
- * ways have independent lists of supported page sizes sharing a
- * common encoding with PTE entries; the encoding is the index into
- * this list; unsupported sizes for a given way are zero in the list;
- * selecting unsupported sizes results in undefined hardware behaviour;
- * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

- * find_ms_setbit
- *
- * This macro finds the most significant bit that is set in <as>
- * and return its index + <base> in <ad>, or <base> - 1 if <as> is zero.
- * The index counts starting at zero for the lsbit, so the return
- * value ranges from <base>-1 (no bit set) to <base>+31 (msbit set).
- *
- * Parameters:
- * <ad> destination address register (any register)
- * <as> source address register
- * <at> temporary address register (must be different than <as>)
- * <base> constant value added to result (usually 0 or 1)
- * On entry:
- * <ad> = undefined if different than <as>
- * <as> = value whose most significant set bit is to be found
- * <at> = undefined
- * no other registers are used by this macro.
- * On exit:
- * <ad> = <base> + index of msbit set in original <as>,
- * = <base> - 1 if original <as> was zero.
- * <as> clobbered (if not <ad>)
- * <at> clobbered (if not <ad>)
- * Example:
- * find_ms_setbit a0, a4, a0, 0 -- return in a0 index of msbit set in a4

- * floop, floopnez, floopgtz, floopend
- *
- * These macros are used for fast inner loops that
- * work whether or not the Loops options is configured.
- * If the Loops option is configured, they simply use
- * the zero-overhead LOOP instructions; otherwise
- * they use explicit decrement and branch instructions.
- *
- * They are used in pairs, with floop, floopnez or floopgtz
- * at the beginning of the loop, and floopend at the end.
- *
- * Each pair of loop macro calls must be given the loop count
- * address register and a unique label for that loop.
- *
- * Example:
- *
- * movi a3, 16 // loop 16 times
- * floop a3, myloop1
- * :
- * bnez a7, end1 // exit loop if a7 != 0
- * :
- * floopend a3, myloop1
- * end1:
- *
- * Like the LOOP instructions, these macros cannot be
- * nested, must include at least one instruction,
- * cannot call functions inside the loop, etc.
- * The loop can be exited by jumping to the instruction
- * following floopend (or elsewhere outside the loop),
- * or continued by jumping to a NOP instruction placed
- * immediately before floopend.
- *
- * Unlike LOOP instructions, the register passed to floop*
- * cannot be used inside the loop, because it is used as
- * the loop counter if the Loops option is not configured.
- * And its value is undefined after exiting the loop.
- * And because the loop counter register is active inside
- * the loop, you can't easily use this construct to loop
- * across a register file using ROTW as you might with LOOP
- * instructions, unless you copy the loop register along.

- * window_spill{4,8,12}
- *
- * These macros spill callers' register windows to the stack.
- * They work for both privileged and non-privileged tasks.
- * Must be called from a windowed ABI context, eg. within
- * a windowed ABI function (ie. valid stack frame, window
- * exceptions enabled, not in exception mode, etc).
- *
- * This macro requires a single invocation of the window_spill_common
- * macro in the same assembly unit and section.
- *
- * Note that using window_spill{4,8,12} macros is more efficient
- * than calling a function implemented using window_spill_function,
- * because the latter needs extra code to figure out the size of
- * the call to the spilling function.
- *
- * Example usage:
- *
- * .text
- * .align 4
- * .global some_function
- * .type some_function,@function
- * some_function:
- * entry a1, 16
- * :
- * :
- *
- * window_spill4 // spill windows of some_function's callers; preserves a0..a3 only;
- * // to use window_spill{8,12} in this example function we'd have
- * // to increase space allocated by the entry instruction, because
- * // 16 bytes only allows call4; 32 or 48 bytes (+locals) are needed
- * // for call8/window_spill8 or call12/window_spill12 respectively.
- * :
- *
- * retw
- *
- * window_spill_common // instantiates code used by window_spill4
- *
- *
- * On entry:
- * none (if window_spill4)
- * stack frame has enough space allocated for call8 (if window_spill8)
- * stack frame has enough space allocated for call12 (if window_spill12)
- * On exit:
- * a4..a15 clobbered (if window_spill4)
- * a8..a15 clobbered (if window_spill8)
- * a12..a15 clobbered (if window_spill12)

- *
- * Release MAJOR MINOR Comment
- * ======= ===== ===== =======
- * T1015.n n/a n/a (HAL not yet available)
- * T1020.{0,1,2} 0 1 (HAL beta)
- * T1020.{3,4} 0 2 First release.
- * T1020.n (n>4) 0 2 or >3 (TBD)
- * T1030.0 0 1 (HAL beta)
- * T1030.{1,2} 0 3 Equivalent to first release.
- * T1030.n (n>=3) 0 >= 3 (TBD)
- * T1040.n 1040 n Full CHAL available from T1040.2
- * T1050.n 1050 n Current release.
- *
- *
- * Note: there is a distinction between the software release with
- * which something is compiled (accessible using XTHAL_RELEASE_* macros)
- * and the software release with which the HAL library was compiled
- * (accessible using Xthal_release_* global variables). This
- * distinction is particularly relevant for vendors that distribute
- * configuration-independent binaries (eg. an OS), where their customer
- * might link it with a HAL of a different Xtensa software release.
- * In this case, it may be appropriate for the OS to verify at run-time
- * whether XTHAL_RELEASE_* and Xthal_release_* are compatible.
- * [Guidelines as to which release is compatible with which are not
- * currently provided explicitly, but might be inferred from reading
- * OSKit documentation for all releases -- compatibility is also highly
- * dependent on which HAL features are used. Each release is usually
- * backward compatible, with very few exceptions if any.]
- *
- * Notes:
- * Tornado 2.0 supported in T1020.3+, T1030.1+, and T1040.{0,1} only.
- * Tornado 2.0.2 supported in T1040.2+, and T1050.
- * Compile-time HAL port of NucleusPlus supported by T1040.2+ and T1050.

- *
- * These services behave largely as if they had been invoked

- * (eg. files accessed are those of the simulator host).
- * However, these SIMCALLs model a virtual operating system
- * so that various definitions, bit assignments etc
- * (eg. open mode bits, errno values, etc) are independent
- * of the host operating system used to run the simulation.
- * Rather these definitions are specific to the Xtensa ISS.
- * This way Xtensa ISA code written to use these SIMCALLs
- * can (in principle) be simulated on any host.
- *
- * Up to 6 parameters are passed in registers a3 to a8
- * (note the 6th parameter isn't passed on the stack,
- * unlike windowed function calling conventions).
- * The return value is in a2. A negative value in the
- * range -4096 to -1 indicates a negated error code to be
- * reported in errno with a return value of -1, otherwise

- * Device addresses.

- * Note: for endianness-independence, use 32-bit loads and stores for all
- * register accesses to Ethernet, DUART and LED devices. Undefined bits
- * may need to be masked out if needed when reading if the actual register
- * size is smaller than 32 bits.
- *
- * Note: XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
- * relative to the processor. So 32-bit registers are accessed consistently
- * from both big and little endian processors. However, this means byte
- * sequences are not consistent between big and little endian processors.
- * This is fine for RAM, and for ROM if ROM is created for a specific
- * processor (and thus has correct byte sequences). However this may be
- * unexpected for Flash, which might contain a file-system that one wants
- * to use for multiple processor configurations (eg. the Flash might contain
- * the Ethernet card's address, endianness-independent application data, etc).
- * That is, byte sequences written in Flash by a core of a given endianness
- * will be byte-swapped when seen by a core of the other endianness.
- * Someone implementing an endianness-independent Flash file system will
- * likely handle this byte-swapping issue in the Flash driver software.

- ensure that exported files do not attempt to include files which
- were not exported, etc.
-
- If you're making modifications to header files which are
- relevant for userspace, say 'Y', and check the headers
- exported to $(INSTALL_HDR_PATH) (usually 'usr/include' in
- your build tree), to make sure they're suitable.

+ Generic support for BUG()
+
+ This respects the following config options:
+
+ CONFIG_BUG - emit BUG traps. Nothing happens without this.
+ CONFIG_GENERIC_BUG - enable this code.
+ CONFIG_DEBUG_BUGVERBOSE - emit full file+line information for each BUG
+
+ CONFIG_BUG and CONFIG_DEBUG_BUGVERBOSE are potentially user-settable
+ (though they're generally always on).
+
+ CONFIG_GENERIC_BUG is set by each architecture using this code.
+
+ To use this, your architecture must:
+
+ 1. Set up the config options:
+ - Enable CONFIG_GENERIC_BUG if CONFIG_BUG
+
+ 2. Implement BUG (and optionally BUG_ON, WARN, WARN_ON)
+ - Define HAVE_ARCH_BUG
+ - Implement BUG() to generate a faulting instruction
+ - NOTE: struct bug_entry does not have "file" or "line" entries
+ when CONFIG_DEBUG_BUGVERBOSE is not enabled, so you must generate
+ the values accordingly.
+
+ 3. Implement the trap
+ - In the illegal instruction trap handler (typically), verify
+ that the fault was in kernel mode, and call report_bug()
+ - report_bug() will return whether it was a false alarm, a warning,
+ or an actual bug.
+ - You must implement the is_valid_bugaddr(bugaddr) callback which
+ returns true if the eip is a real kernel address, and it points
+ to the expected BUG trap instruction.

+ * This function sees both locally originated IP packets and forwarded
* IP packets (in both cases the destination device is a bridge
* device). It also sees bridged-and-DNAT'ed packets.
- * To be able to filter on the physical bridge devices (with the physdev
- * module), we steal packets destined to a bridge device away from the
- * PF_INET/FORWARD and PF_INET/OUTPUT hook functions, and give them back later,
- * when we have determined the real output device. This is done in here.
*
* If (nf_bridge->mask & BRNF_BRIDGED_DNAT) then the packet is bridged
* and we fake the PF_BRIDGE/FORWARD hook. The function br_nf_forward()
* will then fake the PF_INET/FORWARD hook. br_nf_local_out() has priority
* NF_BR_PRI_FIRST, so no relevant PF_BRIDGE/INPUT functions have been nor
* will be executed.
- * Otherwise, if nf_bridge->physindev is NULL, the bridge-nf code never touched
- * this packet before, and so the packet was locally originated. We fake
- * the PF_INET/LOCAL_OUT hook.
- * Finally, if nf_bridge->physindev isn't NULL, then the packet was IP routed,
- * so we fake the PF_INET/FORWARD hook. ip_sabotage_out() makes sure
- * even routed packets that didn't arrive on a bridge interface have their
