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

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
46 it has been started.

676 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
677 watchdog timer that will reboot the machine after its second
678 expiration. The expiration time can be configured with the
679 "heartbeat" parameter.
680
681 On some motherboards the driver may fail to reset the chipset's
682 NO_REBOOT flag which prevents the watchdog from rebooting the
683 machine. If this is the case you will get a kernel message like
684 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

703 This driver can be used with the watchdog timer found on some
704 single board computers, namely the 6010 PII based computer.
705 It may well work with other cards. It reads port 0x443 to enable
706 and re-set the watchdog timer, and reads port 0x45 to disable
707 the watchdog. If you have a card that behave in similar ways,
708 you can probably make this driver work with your card as well.

1062 Freescale PowerPC processors. So far this driver supports:
Anton Vorontsov0d7b1012008-07-03 23:51:36 -07001063 - MPC8xx watchdogs

1139 This driver adds watchdog support for the integrated watchdog in the
1140 SuperH processors. If you have one of these processors and wish
1141 to have watchdog support enabled, say Y, otherwise say N.
1142
1143 As a side note, saying Y here will automatically boost HZ to 1000
1144 so that the timer has a chance to clear the overflow counter. On
1145 slower systems (such as the SH-2 and SH-3) this will likely yield
1146 some performance issues. As such, the WDT should be avoided here
1147 unless it is absolutely necessary.
