-If you have high-res timers compiled into the kernel, the driver will

+If your IPMI interface does not support interrupts and is a KCS or

these interfaces suck.
The driver supports a hot add and remove of interfaces. This way,
interfaces can be added or removed after the kernel is up and running.

+What: sys_sysctl
+When: September 2010
+Option: CONFIG_SYSCTL_SYSCALL
+Why: The same information is available in a more convenient from
+ /proc/sys, and none of the sysctl variables appear to be
+ important performance wise.
+
+ Binary sysctls are a long standing source of subtle kernel
+ bugs and security issues.
+
+ When I looked several months ago all I could find after
+ searching several distributions were 5 user space programs and
+ glibc (which falls back to /proc/sys) using this syscall.
+
+ The man page for sysctl(2) documents it as unusable for user
+ space programs.
+
+ sysctl(2) is not generally ABI compatible to a 32bit user
+ space application on a 64bit and a 32bit kernel.
+
+ For the last several months the policy has been no new binary
+ sysctls and no one has put forward an argument to use them.
+
+ Binary sysctls issues seem to keep happening appearing so
+ properly deprecating them (with a warning to user space) and a
+ 2 year grace warning period will mean eventually we can kill
+ them and end the pain.

Any atomic operation that modifies some state in memory and returns information
about the state (old or new) implies an SMP-conditional general memory barrier
-(smp_mb()) on each side of the actual operation. These include:
+(smp_mb()) on each side of the actual operation (with the exception of
+explicit lock operations, described later). These include:
xchg();
cmpxchg();
do need memory barriers as a lock primitive generally has to do things in a
specific order.
-
Basically, each usage case has to be carefully considered as to whether memory
barriers are needed or not.
+The following operations are special locking primitives:
+
+ test_and_set_bit_lock();
+ clear_bit_unlock();
+ __clear_bit_unlock();
+
+These implement LOCK-class and UNLOCK-class operations. These should be used in
+preference to other operations when implementing locking primitives, because
+their implementations can be optimised on many architectures.
+
[!] Note that special memory barrier primitives are available for these
situations because on some CPUs the atomic instructions used imply full memory
barriers, and so barrier instructions are superfluous in conjunction with them,

In case the STD does not work on your system even in the minimal configuration
and compiling more drivers as modules is not practical or some modules cannot
be unloaded, you can use one of the more advanced debugging techniques to find
-the problem. First, if there is a serial port in your box, you can set the
-CONFIG_DISABLE_CONSOLE_SUSPEND kernel configuration option and try to log kernel
+the problem. First, if there is a serial port in your box, you can boot the
+kernel with the 'no_console_suspend' parameter and try to log kernel
messages using the serial console. This may provide you with some information
about the reasons of the suspend (resume) failure. Alternatively, it may be
possible to use a FireWire port for debugging with firescope
Namely, as the first step of the hibernation procedure the function
freeze_processes() (defined in kernel/power/process.c) is called. It executes
try_to_freeze_tasks() that sets TIF_FREEZE for all of the freezable tasks and
-sends a fake signal to each of them. A task that receives such a signal and has
-TIF_FREEZE set, should react to it by calling the refrigerator() function
-(defined in kernel/power/process.c), which sets the task's PF_FROZEN flag,
-changes its state to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is
-cleared for it. Then, we say that the task is 'frozen' and therefore the set of
-functions handling this mechanism is called 'the freezer' (these functions are
+either wakes them up, if they are kernel threads, or sends fake signals to them,
+if they are user space processes. A task that has TIF_FREEZE set, should react
+to it by calling the function called refrigerator() (defined in
+kernel/power/process.c), which sets the task's PF_FROZEN flag, changes its state
+to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is cleared for it.
+Then, we say that the task is 'frozen' and therefore the set of functions
+handling this mechanism is referred to as 'the freezer' (these functions are
defined in kernel/power/process.c and include/linux/freezer.h). User space
processes are generally frozen before kernel threads.
For user space processes try_to_freeze() is called automatically from the
signal-handling code, but the freezable kernel threads need to call it
-explicitly in suitable places. The code to do this may look like the following:
+explicitly in suitable places or use the wait_event_freezable() or
+wait_event_freezable_timeout() macros (defined in include/linux/freezer.h)
+that combine interruptible sleep with checking if TIF_FREEZE is set and calling
+try_to_freeze(). The main loop of a freezable kernel thread may look like the
+following one:
+ set_freezable();
do {
hub_events();
- wait_event_interruptible(khubd_wait,
- !list_empty(&hub_event_list));
- try_to_freeze();
- } while (!signal_pending(current));
+ wait_event_freezable(khubd_wait,
+ !list_empty(&hub_event_list) ||
+ kthread_should_stop());
+ } while (!kthread_should_stop() || !list_empty(&hub_event_list));
(from drivers/usb/core/hub.c::hub_thread()).
If a freezable kernel thread fails to call try_to_freeze() after the freezer has
set TIF_FREEZE for it, the freezing of tasks will fail and the entire
hibernation operation will be cancelled. For this reason, freezable kernel
-threads must call try_to_freeze() somewhere.
+threads must call try_to_freeze() somewhere or use one of the
+wait_event_freezable() and wait_event_freezable_timeout() macros.
After the system memory state has been restored from a hibernation image and
devices have been reinitialized, the function thaw_processes() is called in
The majority of these are user space processes, but if any of the kernel threads
may cause something like this to happen, they have to be freezable.
-2. The second reason is to prevent user space processes and some kernel threads
+2. Next, to create the hibernation image we need to free a sufficient amount of
+memory (approximately 50% of available RAM) and we need to do that before
+devices are deactivated, because we generally need them for swapping out. Then,
+after the memory for the image has been freed, we don't want tasks to allocate
+additional memory and we prevent them from doing that by freezing them earlier.
+[Of course, this also means that device drivers should not allocate substantial
+amounts of memory from their .suspend() callbacks before hibernation, but this
+is e separate issue.]
+
+3. The third reason is to prevent user space processes and some kernel threads
from interfering with the suspending and resuming of devices. A user space
process running on a second CPU while we are suspending devices may, for
example, be troublesome and without the freezing of tasks we would need some
thawed after the driver's .resume() callback has run, so it won't be accessing
the device while it's suspended.
-3. Another reason for freezing tasks is to prevent user space processes from
+4. Another reason for freezing tasks is to prevent user space processes from
realizing that hibernation (or suspend) operation takes place. Ideally, user
space processes should not notice that such a system-wide operation has occurred
and should continue running without any problems after the restore (or resume
/sys/power/disk controls the operating mode of the suspend-to-disk
mechanism. Suspend-to-disk can be handled in several ways. We have a
few options for putting the system to sleep - using the platform driver
-(e.g. ACPI or other pm_ops), powering off the system or rebooting the
+(e.g. ACPI or other suspend_ops), powering off the system or rebooting the
system (for testing).
Additionally, /sys/power/disk can be used to turn on one of the two testing
+++ /dev/null
-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-This soundcard does not have any hardware MIDI synthesizer;
-MIDI synthesis has to be done in software. To allow this
-the driver/soundcard supports two PCM (/dev/dsp) interfaces.
-
-There is a freely available software package that allows
-MIDI file playback on this soundcard called Timidity.
-See http://www.cgs.fi/~tt/timidity/.

- bool "Watchdog Timer Support"
- ---help---
- If you say Y here (and to one of the following options) and create a
- character special file /dev/watchdog with major number 10 and minor
- number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
- subsequently opening the file and then failing to write to it for
- longer than 1 minute will result in rebooting the machine. This
- could be useful for a networked machine that needs to come back
- on-line as fast as possible after a lock-up. There's both a watchdog
- implementation entirely in software (which can sometimes fail to
- reboot the machine) and a driver for hardware watchdog boards, which
- are more robust and can also keep track of the temperature inside
- your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
- in the kernel source.
-
- The watchdog is usually used together with the watchdog daemon
- which is available from
- <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
- also monitor NFS connections and can reboot the machine when the process
- table is full.
-
- If unsure, say N.

- to stop the timer if the process managing it closes the file
- /dev/watchdog. It's always remotely possible that this process might
- get killed. If you say Y here, the watchdog cannot be stopped once

-/*
- * Theory of Operation:
- * The Watch-Dog Timer is provided to ensure that standalone
- * Systems can always recover from catastrophic conditions that
- * caused the CPU to crash. This condition may have occured by
- * external EMI or a software bug. When the CPU stops working
- * correctly, hardware on the board will either perform a hardware
- * reset (cold boot) or a non-maskable interrupt (NMI) to bring the
- * system back to a known state.
- *
- * The Watch-Dog Timer is controlled by two I/O Ports.
- * 443 hex - Read - Enable or refresh the Watch-Dog Timer
- * 043 hex - Read - Disable the Watch-Dog Timer
- *
- * To enable the Watch-Dog Timer, a read from I/O port 443h must
- * be performed. This will enable and activate the countdown timer
- * which will eventually time out and either reset the CPU or cause
- * an NMI depending on the setting of a jumper. To ensure that this
- * reset condition does not occur, the Watch-Dog Timer must be
- * periodically refreshed by reading the same I/O port 443h.
- * The Watch-Dog Timer is disabled by reading I/O port 043h.
- *
- * The Watch-Dog Timer Time-Out Period is set via jumpers.
- * It can be 1, 2, 10, 20, 110 or 220 seconds.

- * ALi M7101 PMU Computer Watchdog Timer driver
- *
- * Based on w83877f_wdt.c by Scott Jennings <linuxdrivers@oro.net>
- * and the Cobalt kernel WDT timer driver by Tim Hockin
- * <thockin@cobaltnet.com>
- *
- * (c)2002 Steve Hill <steve@navaho.co.uk>
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.
- *
- * Additions:
- * Aug 23, 2004 - Added use_gpio module parameter for use on revision a1d PMUs
- * found on very old cobalt hardware.

- * Vendor Support: 2
- * Board: Super Micro Computer Inc. P4SBx, P4DPx
- * iTCO chipset: ICH4
- *
- * Code contributed by: R. Seretny <lkpatches@paypc.com>
- * Documentation obtained by R. Seretny from SuperMicro Technical Support
- *
- * To enable Watchdog function:
- * 1. BIOS
- * For P4SBx:
- * BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
- * For P4DPx:
- * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
- * This setting enables or disables Watchdog function. When enabled, the
- * default watchdog timer is set to be 5 minutes (about 4’35”). It is
- * enough to load and run the OS. The application (service or driver) has
- * to take over the control once OS is running up and before watchdog
- * expires.
- *
- * 2. JUMPER
- * For P4SBx: JP39
- * For P4DPx: JP37
- * This jumper is used for safety. Closed is enabled. This jumper
- * prevents user enables watchdog in BIOS by accident.
- *
- * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
- *
- * The documentation lists motherboards P4SBx and P4DPx series as of
- * 20-March-2002. However, this code works flawlessly with much newer
- * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
- *
- * The original iTCO driver as written does not actually reset the
- * watchdog timer on these machines, as a result they reboot after five
- * minutes.
- *
- * NOTE: You may leave the Watchdog function disabled in the SuperMicro
- * BIOS to avoid a "boot-race"... This driver will enable watchdog
- * functionality even if it's disabled in the BIOS once the /dev/watchdog
- * file is opened.

- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system
- * automatically and is defined at I/O port 0443H. To enable the
- * watchdog timer and allow the system to reset, write I/O port 0443H.
- * To disable the timer, write I/O port 0441H for the system to stop the
- * watchdog function. The timer has a tolerance of 20% for its
- * intervals.
- *
- * The following describes how the timer should be programmed.
- *
- * Enabling Watchdog:
- * MOV AX,000FH (Choose the values from 0 to F)
- * MOV DX,0443H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,000FH (Any value is fine.)
- * MOV DX,0441H
- * OUT DX,AX
- *
- * Watchdog timer control table:
- * Level Value Time/sec | Level Value Time/sec
- * 1 F 0 | 9 7 16
- * 2 E 2 | 10 6 18
- * 3 D 4 | 11 5 20
- * 4 C 6 | 12 4 22

- *
- * Version 0.1 (99/04/15):
- * - first version
- *
- * Version 0.2 (99/06/16):
- * - added kernel timer watchdog ping after close
- * since the hardware does not support watchdog shutdown
- *
- * Version 0.3 (99/06/21):
- * - added WDIOC_GETSTATUS and WDIOC_GETSUPPORT ioctl calls
- *
- * Version 0.3.1 (99/06/22):
- * - allow module removal while internal timer is active,
- * print warning about probable reset
- *
- * Version 0.4 (99/11/15):
- * - support for one more type board
- *
- * Version 0.5 (2001/12/14) Matt Domsch <Matt_Domsch@dell.com>
- * - added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
- *
- * Version 0.6 (2002/04/12): Rob Radez <rob@osinvestor.com>
- * - make mixcomwd_opened unsigned,
- * removed lock_kernel/unlock_kernel from mixcomwd_release,
- * modified ioctl a bit to conform to API

- * use the Linux watchdog/timer APIs
- *
- * The Watchdog is configured to reset the MTX-1
- * if it is not triggered for 100 seconds.
- * It should not be triggered more often than 1.6 seconds.
- *
- * A timer triggers the watchdog every 5 seconds, until
- * it is opened for the first time. After the first open
- * it MUST be triggered every 2..95 seconds.

- * PC Watchdog Driver
- * by Ken Hollis (khollis@bitgate.com)
- *
- * Permission granted from Simon Machell (smachell@berkprod.com)
- * Written for the Linux Kernel, and GPLed by Ken Hollis
- *
- * 960107 Added request_region routines, modulized the whole thing.
- * 960108 Fixed end-of-file pointer (Thanks to Dan Hollis), added
- * WD_TIMEOUT define.
- * 960216 Added eof marker on the file, and changed verbose messages.
- * 960716 Made functional and cosmetic changes to the source for
- * inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
- * 960717 Removed read/seek routines, replaced with ioctl. Also, added
- * check_region command due to Alan's suggestion.
- * 960821 Made changes to compile in newer 2.0.x kernels. Added
- * "cold reboot sense" entry.
- * 960825 Made a few changes to code, deleted some defines and made
- * typedefs to replace them. Made heartbeat reset only available
- * via ioctl, and removed the write routine.
- * 960828 Added new items for PC Watchdog Rev.C card.
- * 960829 Changed around all of the IOCTLs, added new features,
- * added watchdog disable/re-enable routines. Added firmware
- * version reporting. Added read routine for temperature.
- * Removed some extra defines, added an autodetect Revision
- * routine.
- * 961006 Revised some documentation, fixed some cosmetic bugs. Made
- * drivers to panic the system if it's overheating at bootup.
- * 961118 Changed some verbiage on some of the output, tidied up
- * code bits, and added compatibility to 2.1.x.
- * 970912 Enabled board on open and disable on close.
- * 971107 Took account of recent VFS changes (broke read).
- * 971210 Disable board on initialisation in case board already ticking.
- * 971222 Changed open/close for temperature handling
- * Michael Meskes <meskes@debian.org>.
- * 980112 Used minor numbers from include/linux/miscdevice.h
- * 990403 Clear reset status after reading control status register in
- * pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
- * 990605 Made changes to code to support Firmware 1.22a, added
- * fairly useless proc entry.
- * 990610 removed said useless proc code for the merge <alan>
- * 000403 Removed last traces of proc code. <davej>
- * 011214 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>
- * Added timeout module option to override default

- *
- * 12/4 - 2000 [Initial revision]
- * 25/4 - 2000 Added /dev/watchdog support
- * 09/5 - 2001 [smj@oro.net] fixed fop_write to "return 1" on success
- * 12/4 - 2002 [rob@osinvestor.com] eliminate fop_read
- * fix possible wdt_is_open race
- * add CONFIG_WATCHDOG_NOWAYOUT support
- * remove lock_kernel/unlock_kernel pairs
- * added KERN_* to printk's
- * got rid of extraneous comments
- * changed watchdog_info to correctly reflect what the driver offers
- * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
- * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
- * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
- * use module_param
- * made timeout (the emulated heartbeat) a module_param
- * made the keepalive ping an internal subroutine
- * made wdt_stop and wdt_start module params
- * added extra printk's for startup problems
- * added MODULE_AUTHOR and MODULE_DESCRIPTION info
- *
- *
- * This WDT driver is different from the other Linux WDT
- * drivers in the following ways:
- * *) The driver will ping the watchdog by itself, because this
- * particular WDT has a very short timeout (one second) and it
- * would be insane to count on any userspace daemon always
- * getting scheduled within that time frame.

- *
- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system automatically
- * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
- * and allow the system to reset, write appropriate values from the table
- * below to I/O port 0120H and 0121H. To disable the timer, write a zero
- * value to I/O port 0121H for the system to stop the watchdog function.
- *
- * The following describes how the timer should be programmed (according to
- * the vendor documentation)
- *
- * Enabling Watchdog:
- * MOV AX,000AH (enable, phase I)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000BH (enable, phase II)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000nH (set multiplier n, from 1-4)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000mH (set base timer m, from 0-F)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Reset timer:
- * MOV AX,000mH (same as set base timer, above)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,0000H (a zero value)
- * MOV DX,0120H
- * OUT DX,AX
- *
- * Watchdog timeout configuration values:
- * N
- * M | 1 2 3 4
- * --|----------------------------------
- * 0 | 0.5s 5s 50s 100s
- * 1 | 1s 10s 100s 200s
- * 2 | 1.5s 15s 150s 300s
- * 3 | 2s 20s 200s 400s
- * 4 | 2.5s 25s 250s 500s
- * 5 | 3s 30s 300s 600s
- * 6 | 3.5s 35s 350s 700s
- * 7 | 4s 40s 400s 800s
- * 8 | 4.5s 45s 450s 900s
- * 9 | 5s 50s 500s 1000s
- * A | 5.5s 55s 550s 1100s
- * B | 6s 60s 600s 1200s

- * E | 7.5s 75s 750s 1500s
- * F | 8s 80s 800s 1600s
- *
- * Another way to say the same things is:

- * For N=2, Timeout = (M+1) * 5s
- * For N=3, Timeout = (M+1) * 50s

- * (c) Copyright 2001 Scott Jennings <linuxdrivers@oro.net>
- * 9/27 - 2001 [Initial release]
- *
- * Additional fixes Alan Cox
- * - Fixed formatting
- * - Removed debug printks
- * - Fixed SMP built kernel deadlock
- * - Switched to private locks not lock_kernel
- * - Used ioremap/writew/readw
- * - Added NOWAYOUT support
- * 4/12 - 2002 Changes by Rob Radez <rob@osinvestor.com>
- * - Change comments
- * - Eliminate fop_llseek
- * - Change CONFIG_WATCHDOG_NOWAYOUT semantics
- * - Add KERN_* tags to printks
- * - fix possible wdt_is_open race
- * - Report proper capabilities in watchdog_info
- * - Add WDIOC_{GETSTATUS, GETBOOTSTATUS, SETTIMEOUT,
- * GETTIMEOUT, SETOPTIONS} ioctls
- * 09/8 - 2003 Changes by Wim Van Sebroeck <wim@iguana.be>
- * - cleanup of trailing spaces
- * - added extra printk's for startup problems
- * - use module_param
- * - made timeout (the emulated heartbeat) a module_param
- * - made the keepalive ping an internal subroutine
- * 3/27 - 2004 Changes by Sean Young <sean@mess.org>
- * - set MMCR_BASE to 0xfffef000
- * - CBAR does not need to be read
- * - removed debugging printks
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.
- *
- * This driver uses memory mapped IO, and spinlock.

- * Default clock division ratio is 5.25 msecs. For an additional table of

- *
- * In order for this to work reliably we need to have HZ set to 1000 or
- * something quite higher than 100 (or we need a proper high-res timer
- * implementation that will deal with this properly), otherwise the 10ms
- * resolution of a jiffy is enough to trigger the overflow. For things like
- * the SH-4 and SH-5, this isn't necessarily that big of a problem, though
- * for the SH-2 and SH-3, this isn't recommended unless the WDT is absolutely
- * necssary.
- *
- * As a result of this timing problem, the only modes that are particularly
- * feasible are the 4096 and the 2048 divisors, which yeild 5.25 and 2.62ms
- * overflow periods respectively.
- *
- * Also, since we can't really expect userspace to be responsive enough
- * before the overflow happens, we maintain two seperate timers .. One in
- * the kernel for clearing out WOVF every 2ms or so (again, this depends on
- * HZ == 1000), and another for monitoring userspace writes to the WDT device.
- *
- * As such, we currently use a configurable heartbeat interval which defaults
- * to 30s. In this case, the userspace daemon is only responsible for periodic
- * writes to the device before the next heartbeat is scheduled. If the daemon
- * misses its deadline, the kernel timer will allow the WDT to overflow.

- * (C) Copyright 2003-2006 Sven Anders <anders@anduras.de>
- *
- * History:
- * 2003 - Created version 1.0 for Linux 2.4.x.
- * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
- * features. Released version 1.1
- *
- * Theory of operation:
- *
- * A Watchdog Timer (WDT) is a hardware circuit that can
- * reset the computer system in case of a software fault.
- * You probably knew that already.
- *
- * Usually a userspace daemon will notify the kernel WDT driver
- * via the /dev/watchdog special device file that userspace is
- * still alive, at regular intervals. When such a notification
- * occurs, the driver will usually tell the hardware watchdog
- * that everything is in order, and that the watchdog should wait
- * for yet another little while to reset the system.
- * If userspace fails (RAM error, kernel bug, whatever), the
- * notifications cease to occur, and the hardware watchdog will
- * reset the system (causing a reboot) after the timeout occurs.
- *
- * Create device with:
- * mknod /dev/watchdog c 10 130
- *
- * For an example userspace keep-alive daemon, see:
- * Documentation/watchdog/watchdog.txt

- *
- * 03/96: Angelo Haritsis <ah@doc.ic.ac.uk> :

- * Added WDIOC_GETTIMEOUT and WDIOC_SETTIMOUT.
- *
- * 20020530 Joel Becker <joel.becker@oracle.com>
- * Added Matt Domsch's nowayout module option.

- *
- * 4/19 - 2001 [Initial revision]
- * 9/27 - 2001 Added spinlocking
- * 4/12 - 2002 [rob@osinvestor.com] Eliminate extra comments
- * Eliminate fop_read
- * Eliminate extra spin_unlock
- * Added KERN_* tags to printks
- * add CONFIG_WATCHDOG_NOWAYOUT support
- * fix possible wdt_is_open race
- * changed watchdog_info to correctly reflect what the driver offers
- * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
- * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
- * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
- * added extra printk's for startup problems
- * use module_param
- * made timeout (the emulated heartbeat) a module_param
- * made the keepalive ping an internal subroutine
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.

+ ---help---
+ If you say Y here (and to one of the following options) and create a
+ character special file /dev/watchdog with major number 10 and minor
+ number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
+ subsequently opening the file and then failing to write to it for
+ longer than 1 minute will result in rebooting the machine. This
+ could be useful for a networked machine that needs to come back
+ on-line as fast as possible after a lock-up. There's both a watchdog
+ implementation entirely in software (which can sometimes fail to
+ reboot the machine) and a driver for hardware watchdog boards, which
+ are more robust and can also keep track of the temperature inside
+ your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
+ in the kernel source.
+
+ The watchdog is usually used together with the watchdog daemon
+ which is available from
+ <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
+ also monitor NFS connections and can reboot the machine when the process
+ table is full.

+/*
+ * Theory of Operation:
+ * The Watch-Dog Timer is provided to ensure that standalone
+ * Systems can always recover from catastrophic conditions that
+ * caused the CPU to crash. This condition may have occured by
+ * external EMI or a software bug. When the CPU stops working
+ * correctly, hardware on the board will either perform a hardware
+ * reset (cold boot) or a non-maskable interrupt (NMI) to bring the
+ * system back to a known state.
+ *
+ * The Watch-Dog Timer is controlled by two I/O Ports.
+ * 443 hex - Read - Enable or refresh the Watch-Dog Timer
+ * 043 hex - Read - Disable the Watch-Dog Timer
+ *
+ * To enable the Watch-Dog Timer, a read from I/O port 443h must
+ * be performed. This will enable and activate the countdown timer
+ * which will eventually time out and either reset the CPU or cause
+ * an NMI depending on the setting of a jumper. To ensure that this
+ * reset condition does not occur, the Watch-Dog Timer must be
+ * periodically refreshed by reading the same I/O port 443h.
+ * The Watch-Dog Timer is disabled by reading I/O port 043h.
+ *
+ * The Watch-Dog Timer Time-Out Period is set via jumpers.
+ * It can be 1, 2, 10, 20, 110 or 220 seconds.

+ *
+ * To enable Watchdog function:
+ * 1. BIOS
+ * For P4SBx:
+ * BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
+ * For P4DPx:
+ * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
+ * This setting enables or disables Watchdog function. When enabled, the
+ * default watchdog timer is set to be 5 minutes (about 4’35”). It is
+ * enough to load and run the OS. The application (service or driver) has
+ * to take over the control once OS is running up and before watchdog
+ * expires.
+ *
+ * 2. JUMPER
+ * For P4SBx: JP39
+ * For P4DPx: JP37
+ * This jumper is used for safety. Closed is enabled. This jumper
+ * prevents user enables watchdog in BIOS by accident.
+ *
+ * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
+ *
+ * The documentation lists motherboards P4SBx and P4DPx series as of
+ * 20-March-2002. However, this code works flawlessly with much newer
+ * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
+ *
+ * The original iTCO driver as written does not actually reset the
+ * watchdog timer on these machines, as a result they reboot after five
+ * minutes.
+ *
+ * NOTE: You may leave the Watchdog function disabled in the SuperMicro
+ * BIOS to avoid a "boot-race"... This driver will enable watchdog
+ * functionality even if it's disabled in the BIOS once the /dev/watchdog
+ * file is opened.

+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system
+ * automatically and is defined at I/O port 0443H. To enable the
+ * watchdog timer and allow the system to reset, write I/O port 0443H.
+ * To disable the timer, write I/O port 0441H for the system to stop the
+ * watchdog function. The timer has a tolerance of 20% for its
+ * intervals.
+ *
+ * The following describes how the timer should be programmed.
+ *
+ * Enabling Watchdog:
+ * MOV AX,000FH (Choose the values from 0 to F)
+ * MOV DX,0443H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,000FH (Any value is fine.)
+ * MOV DX,0441H
+ * OUT DX,AX
+ *
+ * Watchdog timer control table:
+ * Level Value Time/sec | Level Value Time/sec
+ * 1 F 0 | 9 7 16
+ * 2 E 2 | 10 6 18
+ * 3 D 4 | 11 5 20

+ * Version 0.3 (99/06/21):
+ * - added WDIOC_GETSTATUS and WDIOC_GETSUPPORT ioctl calls
+ *
+ * Version 0.3.1 (99/06/22):
+ * - allow module removal while internal timer is active,
+ * print warning about probable reset
+ *
+ * Version 0.4 (99/11/15):
+ * - support for one more type board
+ *
+ * Version 0.5 (2001/12/14) Matt Domsch <Matt_Domsch@dell.com>
+ * - added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
+ *

+ * PC Watchdog Driver
+ * by Ken Hollis (khollis@bitgate.com)
+ *
+ * Permission granted from Simon Machell (smachell@berkprod.com)
+ * Written for the Linux Kernel, and GPLed by Ken Hollis
+ *
+ * 960107 Added request_region routines, modulized the whole thing.
+ * 960108 Fixed end-of-file pointer (Thanks to Dan Hollis), added
+ * WD_TIMEOUT define.
+ * 960216 Added eof marker on the file, and changed verbose messages.
+ * 960716 Made functional and cosmetic changes to the source for
+ * inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
+ * 960717 Removed read/seek routines, replaced with ioctl. Also, added
+ * check_region command due to Alan's suggestion.
+ * 960821 Made changes to compile in newer 2.0.x kernels. Added
+ * "cold reboot sense" entry.
+ * 960825 Made a few changes to code, deleted some defines and made
+ * typedefs to replace them. Made heartbeat reset only available
+ * via ioctl, and removed the write routine.
+ * 960828 Added new items for PC Watchdog Rev.C card.
+ * 960829 Changed around all of the IOCTLs, added new features,
+ * added watchdog disable/re-enable routines. Added firmware
+ * version reporting. Added read routine for temperature.
+ * Removed some extra defines, added an autodetect Revision
+ * routine.
+ * 961006 Revised some documentation, fixed some cosmetic bugs. Made
+ * drivers to panic the system if it's overheating at bootup.
+ * 961118 Changed some verbiage on some of the output, tidied up
+ * code bits, and added compatibility to 2.1.x.
+ * 970912 Enabled board on open and disable on close.
+ * 971107 Took account of recent VFS changes (broke read).
+ * 971210 Disable board on initialisation in case board already ticking.
+ * 971222 Changed open/close for temperature handling
+ * Michael Meskes <meskes@debian.org>.
+ * 980112 Used minor numbers from include/linux/miscdevice.h
+ * 990403 Clear reset status after reading control status register in
+ * pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
+ * 990605 Made changes to code to support Firmware 1.22a, added
+ * fairly useless proc entry.
+ * 990610 removed said useless proc code for the merge <alan>
+ * 000403 Removed last traces of proc code. <davej>
+ * 011214 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>
+ * Added timeout module option to override default

+ * add CONFIG_WATCHDOG_NOWAYOUT support
+ * remove lock_kernel/unlock_kernel pairs

+ *
+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system automatically
+ * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
+ * and allow the system to reset, write appropriate values from the table
+ * below to I/O port 0120H and 0121H. To disable the timer, write a zero
+ * value to I/O port 0121H for the system to stop the watchdog function.
+ *
+ * The following describes how the timer should be programmed (according to
+ * the vendor documentation)
+ *
+ * Enabling Watchdog:
+ * MOV AX,000AH (enable, phase I)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000BH (enable, phase II)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000nH (set multiplier n, from 1-4)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000mH (set base timer m, from 0-F)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Reset timer:
+ * MOV AX,000mH (same as set base timer, above)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,0000H (a zero value)
+ * MOV DX,0120H
+ * OUT DX,AX
+ *
+ * Watchdog timeout configuration values:
+ * N
+ * M | 1 2 3 4
+ * --|----------------------------------
+ * 0 | 0.5s 5s 50s 100s

+ * 9/27 - 2001 [Initial release]
+ *
+ * Additional fixes Alan Cox
+ * - Fixed formatting
+ * - Removed debug printks
+ * - Fixed SMP built kernel deadlock
+ * - Switched to private locks not lock_kernel
+ * - Used ioremap/writew/readw
+ * - Added NOWAYOUT support
+ * 4/12 - 2002 Changes by Rob Radez <rob@osinvestor.com>
+ * - Change comments
+ * - Eliminate fop_llseek
+ * - Change CONFIG_WATCHDOG_NOWAYOUT semantics
+ * - Add KERN_* tags to printks
+ * - fix possible wdt_is_open race
+ * - Report proper capabilities in watchdog_info
+ * - Add WDIOC_{GETSTATUS, GETBOOTSTATUS, SETTIMEOUT,
+ * GETTIMEOUT, SETOPTIONS} ioctls
+ * 09/8 - 2003 Changes by Wim Van Sebroeck <wim@iguana.be>
+ * - cleanup of trailing spaces
+ * - added extra printk's for startup problems
+ * - use module_param
+ * - made timeout (the emulated heartbeat) a module_param
+ * - made the keepalive ping an internal subroutine
+ * 3/27 - 2004 Changes by Sean Young <sean@mess.org>
+ * - set MMCR_BASE to 0xfffef000
+ * - CBAR does not need to be read
+ * - removed debugging printks
+ *
+ * This WDT driver is different from most other Linux WDT
+ * drivers in that the driver will ping the watchdog by itself,
+ * because this particular WDT has a very short timeout (1.6
+ * seconds) and it would be insane to count on any userspace
+ * daemon always getting scheduled within that time frame.
+ *
+ * This driver uses memory mapped IO, and spinlock.

+ * implementation that will deal with this properly), otherwise the 10ms

+ *
+ * As a result of this timing problem, the only modes that are particularly
+ * feasible are the 4096 and the 2048 divisors, which yeild 5.25 and 2.62ms
+ * overflow periods respectively.
+ *
+ * Also, since we can't really expect userspace to be responsive enough
+ * before the overflow happens, we maintain two seperate timers .. One in
+ * the kernel for clearing out WOVF every 2ms or so (again, this depends on
+ * HZ == 1000), and another for monitoring userspace writes to the WDT device.
+ *
+ * As such, we currently use a configurable heartbeat interval which defaults
+ * to 30s. In this case, the userspace daemon is only responsible for periodic
+ * writes to the device before the next heartbeat is scheduled. If the daemon
+ * misses its deadline, the kernel timer will allow the WDT to overflow.

+ *
+ * History:
+ * 2003 - Created version 1.0 for Linux 2.4.x.
+ * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
+ * features. Released version 1.1
+ *
+ * Theory of operation:
+ *
+ * A Watchdog Timer (WDT) is a hardware circuit that can
+ * reset the computer system in case of a software fault.
+ * You probably knew that already.
+ *
+ * Usually a userspace daemon will notify the kernel WDT driver
+ * via the /dev/watchdog special device file that userspace is
+ * still alive, at regular intervals. When such a notification
+ * occurs, the driver will usually tell the hardware watchdog
+ * that everything is in order, and that the watchdog should wait
+ * for yet another little while to reset the system.
+ * If userspace fails (RAM error, kernel bug, whatever), the
+ * notifications cease to occur, and the hardware watchdog will
+ * reset the system (causing a reboot) after the timeout occurs.
+ *
+ * Create device with:
+ * mknod /dev/watchdog c 10 130
+ *
+ * For an example userspace keep-alive daemon, see:
+ * Documentation/watchdog/watchdog.txt

+ * Eliminate fop_read
+ * Eliminate extra spin_unlock
+ * Added KERN_* tags to printks
+ * add CONFIG_WATCHDOG_NOWAYOUT support
+ * fix possible wdt_is_open race
+ * changed watchdog_info to correctly reflect what the driver offers
+ * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
+ * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
+ * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
+ * added extra printk's for startup problems
+ * use module_param
+ * made timeout (the emulated heartbeat) a module_param
+ * made the keepalive ping an internal subroutine
+ *
+ * This WDT driver is different from most other Linux WDT
+ * drivers in that the driver will ping the watchdog by itself,
+ * because this particular WDT has a very short timeout (1.6
+ * seconds) and it would be insane to count on any userspace

- * struct pm_ops - Callbacks for managing platform dependent system sleep
- * states.
- *
- * @valid: Callback to determine if given system sleep state is supported by
- * the platform.
- * Valid (ie. supported) states are advertised in /sys/power/state. Note
- * that it still may be impossible to enter given system sleep state if the
- * conditions aren't right.
- * There is the %pm_valid_only_mem function available that can be assigned
- * to this if the platform only supports mem sleep.
- *
- * @set_target: Tell the platform which system sleep state is going to be
- * entered.
- * @set_target() is executed right prior to suspending devices. The
- * information conveyed to the platform code by @set_target() should be
- * disregarded by the platform as soon as @finish() is executed and if
- * @prepare() fails. If @set_target() fails (ie. returns nonzero),
- * @prepare(), @enter() and @finish() will not be called by the PM core.
- * This callback is optional. However, if it is implemented, the argument
- * passed to @prepare(), @enter() and @finish() is meaningless and should
- * be ignored.
- *
- * @prepare: Prepare the platform for entering the system sleep state indicated
- * by @set_target() or represented by the argument if @set_target() is not
- * implemented.
- * @prepare() is called right after devices have been suspended (ie. the
- * appropriate .suspend() method has been executed for each device) and
- * before the nonboot CPUs are disabled (it is executed with IRQs enabled).
- * This callback is optional. It returns 0 on success or a negative
- * error code otherwise, in which case the system cannot enter the desired
- * sleep state (@enter() and @finish() will not be called in that case).
- *
- * @enter: Enter the system sleep state indicated by @set_target() or
- * represented by the argument if @set_target() is not implemented.

+ *
+ * @pre_snapshot: Prepare the platform for creating the hibernation image.

+ *
+ * @finish: Restore the previous state of the platform after the hibernation

- * linux/sound/oss/dmasound/dmasound_awacs.c
- *
- * PowerMac `AWACS' and `Burgundy' DMA Sound Driver
- * with some limited support for DACA & Tumbler
- *
- * See linux/sound/oss/dmasound/dmasound_core.c for copyright and
- * history prior to 2001/01/26.
- *
- * 26/01/2001 ed 0.1 Iain Sandoe
- * - added version info.
- * - moved dbdma command buffer allocation to PMacXXXSqSetup()
- * - fixed up beep dbdma cmd buffers
- *
- * 08/02/2001 [0.2]
- * - make SNDCTL_DSP_GETFMTS return the correct info for the h/w
- * - move soft format translations to a separate file
- * - [0.3] make SNDCTL_DSP_GETCAPS return correct info.
- * - [0.4] more informative machine name strings.
- * - [0.5]
- * - record changes.
- * - made the default_hard/soft entries.
- * 04/04/2001 [0.6]
- * - minor correction to bit assignments in awacs_defs.h
- * - incorporate mixer changes from 2.2.x back-port.
- * - take out passthru as a rec input (it isn't).
- * - make Input Gain slider work the 'right way up'.
- * - try to make the mixer sliders more logical - so now the
- * input selectors are just two-state (>50% == ON) and the
- * Input Gain slider handles the rest of the gain issues.
- * - try to pick slider representations that most closely match
- * the actual use - e.g. IGain for input gain...
- * - first stab at over/under-run detection.
- * - minor cosmetic changes to IRQ identification.
- * - fix bug where rates > max would be reported as supported.
- * - first stab at over/under-run detection.
- * - make use of i2c for mixer settings conditional on perch
- * rather than cuda (some machines without perch have cuda).
- * - fix bug where TX stops when dbdma status comes up "DEAD"
- * so far only reported on PowerComputing clones ... but.
- * - put in AWACS/Screamer register write timeouts.
- * - part way to partitioning the init() stuff
- * - first pass at 'tumbler' stuff (not support - just an attempt
- * to allow the driver to load on new G4s).
- * 01/02/2002 [0.7] - BenH
- * - all sort of minor bits went in since the latest update, I
- * bumped the version number for that reason
- *
- * 07/26/2002 [0.8] - BenH
- * - More minor bits since last changelog (I should be more careful
- * with those)
- * - Support for snapper & better tumbler integration by Toby Sargeant
- * - Headphone detect for scremer by Julien Blache
- * - More tumbler fixed by Andreas Schwab
- * 11/29/2003 [0.8.1] - Renzo Davoli (King Enzo)
- * - Support for Snapper line in
- * - snapper input resampling (for rates < 44100)
- * - software line gain control
- */

-/* GENERAL FIXME/TODO: check that the assumptions about what is written to
- mac-io is valid for DACA & Tumbler.

- This driver is in bad need of a rewrite. The dbdma code has to be split,
- some proper device-tree parsing code has to be written, etc...

- * Special thanks to Ensoniq
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/dsp1 additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- * there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- * Revision history
- * 04.06.1998 0.1 Initial release
- * Mixer stuff should be overhauled; especially optional AC97 mixer bits
- * should be detected. This results in strange behaviour of some mixer
- * settings, like master volume and mic.
- * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.3 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.4 Fix realplayer problems - dac.count issues
- * 27.10.1998 0.5 Fix joystick support
- * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA
- * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs
- * Don't wake up app until there are fragsize bytes to read/write
- * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Another Alpha fix (wait_src_ready in init routine)
- * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- * Note: joystick address handling might still be wrong on archs
- * other than i386
- * 15.06.1999 0.12 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.13 Add pci_set_master
- * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall
- * added kernel command line option "es1371=joystickaddr"
- * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge
- * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4.
- * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>.
- * module_init/__setup fixes
- * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com>
- * Added detection for ES1371 revision ID so that we can
- * detect the ES1373 and later parts.
- * added AC97 #defines for readability
- * added a /proc file system for dumping hardware state
- * updated SRC and CODEC w/r functions to accommodate bugs
- * in some versions of the ES137x chips.
- * 31.08.1999 0.17 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.18 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 21.10.1999 0.19 Round sampling rates, requested by
- * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp>
- * 27.10.1999 0.20 Added SigmaTel 3D enhancement string
- * Codec ID printing changes
- * 28.10.1999 0.21 More waitqueue races fixed
- * Joe Cotellese <joec@ensoniq.com>
- * Changed PCI detection routine so we can more easily
- * detect ES137x chip and derivatives.
- * 05.01.2000 0.22 Should now work with rev7 boards; patch by
- * Eric Lemar, elemar@cs.washington.edu
- * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver
- * 07.02.2000 0.25 Use ac97_codec
- * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com>
- * Use pci_module_init
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.28 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps
- * the CT5880 revision.
- * suggested by Stephan Müller <smueller@chronox.de>
- * 31.01.2001 0.30 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 14.07.2001 0.31 Add list of laptops needing amplifier control
