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
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process

1036 The TCO (Total Cost of Ownership) timer is a watchdog timer
1037 that will reboot the machine after its second expiration. The
1038 expiration time can be configured with the "heartbeat" parameter.
1039
1040 On some motherboards the driver may fail to reset the chipset's
1041 NO_REBOOT flag which prevents the watchdog from rebooting the

Wim Van Sebroecke0845bf2006-09-02 17:59:54 +02001336 N. This is the driver for the watchdog timer built-in on that
Linus Torvalds1da177e2005-04-16 15:20:36 -07001337 processor using ZF-Logic interface. This watchdog simply watches
1338 your kernel to make sure it doesn't freeze, and if it does, it
1339 reboots your computer after a certain amount of time.

1342 module will be called machzwd.

1348 This is the driver for the built-in watchdog timer on the EPX-C3
1349 Single-board computer made by Winsystems, Inc.
1350
1351 *Note*: This hardware watchdog is not probeable and thus there
1352 is no way to know if writing to its IO address will corrupt
1353 your system or have any real effect. The only way to be sure
1354 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001355 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001356 timer at IO address 0x1ee and 0x1ef. It will write to both those
1357 IO ports. Basically, the assumption is made that if you compile
1358 this driver into your kernel and/or load it as a module, that you
1359 know what you are doing and that you are in fact running on an
1360 EPX-C3 board!
