Linus Torvalds1da177e2005-04-16 15:20:36 -070010 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:

14 longer than 1 minute will result in rebooting the machine. This
15 could be useful for a networked machine that needs to come back

373 This is the driver for the hardware watchdog on Mellanox systems.
374 If you are going to use it, say Y here, otherwise N.
375 This driver can be used together with the watchdog daemon.
376 It can also watch your kernel to make sure it doesn't freeze,
377 and if it does, it reboots your system after a certain amount of
378 time.

1326 The TCO (Total Cost of Ownership) timer is a watchdog timer
1327 that will reboot the machine after its second expiration. The
1328 expiration time can be configured with the "heartbeat" parameter.
1329
1330 On some motherboards the driver may fail to reset the chipset's
1331 NO_REBOOT flag which prevents the watchdog from rebooting the
1332 machine. If this is the case you will get a kernel message like
1333 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

2184 watchdog simply watches your kernel to make sure it doesn't freeze,
2185 and if it does, it reboots your computer after a certain amount of
2186 time.

Linus Torvalds1da177e2005-04-16 15:20:36 -07002197 If you have a WDT500P or WDT501P watchdog board, say Y here,
2198 otherwise N. It is not possible to probe for this board, which means
2199 that you have to inform the kernel about the IO port and IRQ that
2200 is needed (you can do this via the io and irq parameters)

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00002233 If you have a PCI-WDT501 watchdog board then you can enable the
2234 temperature sensor by setting the type parameter to 501.
Linus Torvalds1da177e2005-04-16 15:20:36 -07002235
2236 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
2237 can do this via the tachometer parameter. Only do this if you have a
2238 fan tachometer actually set up.
