9 If you say Y here (and to one of the following options) and create a
10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back

22 The watchdog is usually used together with the watchdog daemon
23 which is available from

25 also monitor NFS connections and can reboot the machine when the process

1025 The TCO (Total Cost of Ownership) timer is a watchdog timer
1026 that will reboot the machine after its second expiration. The
1027 expiration time can be configured with the "heartbeat" parameter.
1028
1029 On some motherboards the driver may fail to reset the chipset's
1030 NO_REBOOT flag which prevents the watchdog from rebooting the
1031 machine. If this is the case you will get a kernel message like
1032 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1338 This is the driver for the built-in watchdog timer on the EPX-C3
1339 Single-board computer made by Winsystems, Inc.
1340
1341 *Note*: This hardware watchdog is not probeable and thus there
1342 is no way to know if writing to its IO address will corrupt
1343 your system or have any real effect. The only way to be sure
1344 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001345 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001346 timer at IO address 0x1ee and 0x1ef. It will write to both those
1347 IO ports. Basically, the assumption is made that if you compile
1348 this driver into your kernel and/or load it as a module, that you
1349 know what you are doing and that you are in fact running on an
1350 EPX-C3 board!

1648 This driver is for a SoC level watchdog that exists on some
1649 Freescale PowerPC processors. So far this driver supports:
Anton Vorontsov0d7b1012008-07-03 23:51:36 -07001650 - MPC8xx watchdogs
Anton Vorontsov28acd022008-07-03 23:51:34 -07001651 - MPC83xx watchdogs
1652 - MPC86xx watchdogs
1653
1654 For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.

1745 to have watchdog support enabled, say Y, otherwise say N.

1748 so that the timer has a chance to clear the overflow counter. On
1749 slower systems (such as the SH-2 and SH-3) this will likely yield
1750 some performance issues. As such, the WDT should be avoided here
