10 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
13 subsequently opening the file and then failing to write to it for
14 longer than 1 minute will result in rebooting the machine. This
15 could be useful for a networked machine that needs to come back
e0845bf4 16 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
17 implementation entirely in software (which can sometimes fail to
18 reboot the machine) and a driver for hardware watchdog boards, which
19 are more robust and can also keep track of the temperature inside
e403149c
DH
20 your computer. For details, read
21 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
22
23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process
27 table is full.

56 been loaded until control is taken over from userspace using the

1943
1944 As a side note, saying Y here will automatically boost HZ to 1000
1945 so that the timer has a chance to clear the overflow counter. On
1946 slower systems (such as the SH-2 and SH-3) this will likely yield
