the WDT card does, only it doesn't require an IRQ to run.  Furthermore,
the Revision C card allows you to monitor any IO Port to automatically
trigger the card into being reset.  This way you can make the card
monitor hard drive status, or anything else you need.

The Watchdog Driver has one basic role: to talk to the card and send
signals to it so it doesn't reset your computer ... at least during
normal operation.

The Watchdog Driver will automatically find your watchdog card, and will
attach a running driver for use with that card.  After the watchdog
drivers have initialized, you can then talk to the card using a PC
Watchdog program.

I suggest putting a "watchdog -d" before the beginning of an fsck, and
a "watchdog -e -t 1" immediately after the end of an fsck.  (Remember
to run the program with an "&" to run it in the background!)

If you want to write a program to be compatible with the PC Watchdog
driver, simply use of modify the watchdog test program:
tools/testing/selftests/watchdog/watchdog-test.c


Other IOCTL functions include:

       WDIOC_GETSUPPORT
               This returns the support of the card itself.  This
               returns in structure "PCWDS" which returns:

                       options = WDIOS_TEMPPANIC
                                 (This card supports temperature)
                       firmware_version = xxxx
                                 (Firmware version of the card)

       WDIOC_GETSTATUS
               This returns the status of the card, with the bits of
               WDIOF_* bitwise-anded into the value.  (The comments
               are in include/uapi/linux/watchdog.h)

       WDIOC_GETBOOTSTATUS
               This returns the status of the card that was reported
               at bootup.

       WDIOC_GETTEMP
               This returns the temperature of the card.  (You can also
               read /dev/watchdog, which gives a temperature update
               every second.)

       WDIOC_SETOPTIONS
               This lets you set the options of the card.  You can either
               enable or disable the card this way.

       WDIOC_KEEPALIVE
               This pings the card to tell it not to reset your computer.

And that's all she wrote!
