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

16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside

Linus Torvalds1da177e2005-04-16 15:20:36 -070020
21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
25 table is full.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

1076
1077 *Note*: This hardware watchdog is not probeable and thus there
1078 is no way to know if writing to its IO address will corrupt
1079 your system or have any real effect. The only way to be sure
1080 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001081 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001082 timer at IO address 0x1ee and 0x1ef. It will write to both those
1083 IO ports. Basically, the assumption is made that if you compile
1084 this driver into your kernel and/or load it as a module, that you

1390 This driver adds watchdog support for the integrated watchdog in the
1391 SuperH processors. If you have one of these processors and wish
1392 to have watchdog support enabled, say Y, otherwise say N.
1393
1394 As a side note, saying Y here will automatically boost HZ to 1000
1395 so that the timer has a chance to clear the overflow counter. On
1396 slower systems (such as the SH-2 and SH-3) this will likely yield
1397 some performance issues. As such, the WDT should be avoided here
1398 unless it is absolutely necessary.
