config WATCHDOG
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
online 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.
config WATCHDOG_NOWAYOUT
bool "Disable watchdog shutdown on close"
depends on WATCHDOG
help
The default watchdog behaviour (which you get if you say N here) is
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
it has been started.

config SOFT_WATCHDOG
tristate "Software watchdog"
depends on WATCHDOG
help
A software monitoring watchdog. This will fail to reboot your system
from some situations that the hardware watchdog will recover
from. Equally it's a lot cheaper to install.
To compile this driver as a module, choose M here: the
module will be called softdog.
# ARM Architecture
config AT91_WATCHDOG
tristate "AT91RM9200 watchdog"

Watchdog timer embedded into AT91RM9200 chips. This will reboot your
system when the timeout is reached.
config 21285_WATCHDOG
tristate "DC21285 watchdog"
depends on WATCHDOG && FOOTBRIDGE
help
The Intel Footbridge chip contains a builtin watchdog circuit. Say Y
here if you wish to use this. Alternatively say M to compile the
driver as a module, which will be called wdt285.
This driver does not work on all machines. In particular, early CATS
boards have hardware problems that will cause the machine to simply
lock up if the watchdog fires.
"If in doubt, leave it out" - say N.
config 977_WATCHDOG
tristate "NetWinder WB83C977 watchdog"
depends on WATCHDOG && FOOTBRIDGE && ARCH_NETWINDER

Say Y here if to include support for the watchdog timer
in the Intel IXP4xx network processors. This driver can
be built as a module by choosing M. The module will
be called ixp4xx_wdt.
Note: The internal IXP4xx watchdog does a soft CPU reset
which doesn't reset any peripherals. There are circumstances
where the watchdog will fail to reset the board correctly
(e.g., if the boot ROM is in an unreadable state).
Say N if you are unsure.
config S3C2410_WATCHDOG
tristate "S3C2410 Watchdog"
depends on WATCHDOG && ARCH_S3C2410
help
Watchdog timer block in the Samsung S3C2410 chips. This will
reboot the system when the timer expires with the watchdog
enabled.
The driver is limited by the speed of the system's PCLK
signal, so with reasonably fast systems (PCLK around 50-66MHz)
then watchdog intervals of over approximately 20seconds are
unavailable.

CPU-1410 cards. These are PC/104 SBCs. Spec sheets and product
information are at <http://www.eurotech.it/>.
config IB700_WDT
tristate "IB700 SBC Watchdog Timer"
depends on WATCHDOG && X86
---help---
This is the driver for the hardware watchdog on the IB700 Single
Board Computer produced by TMC Technology (www.tmc-uk.com). This watchdog
simply watches your kernel to make sure it doesn't freeze, and if
it does, it reboots your computer after a certain amount of time.
This driver is like the WDT501 driver but for slightly different hardware.
To compile this driver as a module, choose M here: the
module will be called ib700wdt.
Most people will say N.
config IBMASR

config I8XX_TCO
tristate "Intel i8xx TCO Timer/Watchdog"
depends on WATCHDOG && (X86 || IA64) && PCI
---help---
Hardware driver for the TCO timer built into the Intel 82801
I/O Controller Hub family. The TCO (Total Cost of Ownership)
timer is a watchdog timer that will reboot the machine after
its second expiration. The expiration time can be configured
with the "heartbeat" parameter.
On some motherboards the driver may fail to reset the chipset's
NO_REBOOT flag which prevents the watchdog from rebooting the
machine. If this is the case you will get a kernel message like
"failed to reset NO_REBOOT flag, reboot disabled by hardware".
To compile this driver as a module, choose M here: the
module will be called i8xx_tco.
config SC1200_WDT

config 60XX_WDT
tristate "SBC-60XX Watchdog Timer"
depends on WATCHDOG && X86
help
This driver can be used with the watchdog timer found on some
single board computers, namely the 6010 PII based computer.
It may well work with other cards. It reads port 0x443 to enable
and re-set the watchdog timer, and reads port 0x45 to disable
the watchdog. If you have a card that behave in similar ways,
you can probably make this driver work with your card as well.
You can compile this driver directly into the kernel, or use
it as a module. The module will be called sbc60xxwdt.

If you are using a ZF Micro MachZ processor, say Y here, otherwise
N. This is the driver for the watchdog timer builtin on that
processor using ZF-Logic interface. This watchdog simply watches
your kernel to make sure it doesn't freeze, and if it does, it
reboots your computer after a certain amount of time.
To compile this driver as a module, choose M here: the
module will be called machzwd.
config SBC_EPX_C3_WATCHDOG
tristate "Winsystems SBC EPX-C3 watchdog"
depends on WATCHDOG && X86
---help---
This is the driver for the built-in watchdog timer on the EPX-C3
Single-board computer made by Winsystems, Inc.
*Note*: This hardware watchdog is not probeable and thus there
is no way to know if writing to its IO address will corrupt
your system or have any real effect. The only way to be sure
that this driver does what you want is to make sure you
are running it on an EPX-C3 from Winsystems with the watchdog
timer at IO address 0x1ee and 0x1ef. It will write to both those
IO ports. Basically, the assumption is made that if you compile
this driver into your kernel and/or load it as a module, that you
know what you are doing and that you are in fact running on an
EPX-C3 board!
To compile this driver as a module, choose M here: the
module will be called sbc_epx_c3.

# SUPERH Architecture

help
This driver adds watchdog support for the integrated watchdog in the
SuperH processors. If you have one of these processors and wish
to have watchdog support enabled, say Y, otherwise say N.
As a side note, saying Y here will automatically boost HZ to 1000
so that the timer has a chance to clear the overflow counter. On
slower systems (such as the SH-2 and SH-3) this will likely yield
some performance issues. As such, the WDT should be avoided here
unless it is absolutely necessary.
To compile this driver as a module, choose M here: the
module will be called shwdt.
