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.

Linus Torvalds1da177e2005-04-16 15:20:36 -070041 help
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
46 it has been started.

1062 This is the driver for the built-in watchdog timer on the EPX-C3
1063 Single-board computer made by Winsystems, Inc.
1064
1065 *Note*: This hardware watchdog is not probeable and thus there
1066 is no way to know if writing to its IO address will corrupt
1067 your system or have any real effect. The only way to be sure
1068 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001069 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001070 timer at IO address 0x1ee and 0x1ef. It will write to both those
1071 IO ports. Basically, the assumption is made that if you compile
1072 this driver into your kernel and/or load it as a module, that you
1073 know what you are doing and that you are in fact running on an
1074 EPX-C3 board!

1077 module will be called sbc_epx_c3.

1370 As a side note, saying Y here will automatically boost HZ to 1000
1371 so that the timer has a chance to clear the overflow counter. On
1372 slower systems (such as the SH-2 and SH-3) this will likely yield

1432 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1433 This card simply watches your kernel to make sure it doesn't freeze,
1434 and if it does, it reboots your computer after a certain amount of
1435 time. This driver is like the WDT501 driver but for different
1436 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1437 watchdog cards can be ordered from <http://www.berkprod.com/>.

1462 If you have a WDT500P or WDT501P watchdog board, say Y here,
1463 otherwise N. It is not possible to probe for this board, which means

1465 is needed (you can do this via the io and irq parameters)
