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

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

Wim Van Sebroecke0845bf2006-09-02 17:59:54 +02001051 N. This is the driver for the watchdog timer built-in on that
Linus Torvalds1da177e2005-04-16 15:20:36 -07001052 processor using ZF-Logic interface. This watchdog simply watches
1053 your kernel to make sure it doesn't freeze, and if it does, it
1054 reboots your computer after a certain amount of time.
1055
1056 To compile this driver as a module, choose M here: the
1057 module will be called machzwd.

1064 Single-board computer made by Winsystems, Inc.
1065
1066 *Note*: This hardware watchdog is not probeable and thus there
1067 is no way to know if writing to its IO address will corrupt
1068 your system or have any real effect. The only way to be sure
1069 that this driver does what you want is to make sure you
Matt LaPlante2621e2a2006-07-05 01:20:51 +00001070 are running it on an EPX-C3 from Winsystems with the watchdog
Calin A. Culianueed65652006-01-14 13:20:46 -08001071 timer at IO address 0x1ee and 0x1ef. It will write to both those
1072 IO ports. Basically, the assumption is made that if you compile
1073 this driver into your kernel and/or load it as a module, that you
1074 know what you are doing and that you are in fact running on an
1075 EPX-C3 board!

1372 so that the timer has a chance to clear the overflow counter. On

1433 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1434 This card simply watches your kernel to make sure it doesn't freeze,
1435 and if it does, it reboots your computer after a certain amount of
1436 time. This driver is like the WDT501 driver but for different
1437 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1438 watchdog cards can be ordered from <http://www.berkprod.com/>.
