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

22 The watchdog is usually used together with the watchdog daemon
23 which is available from

25 also monitor NFS connections and can reboot the machine when the process

856 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.

858 Entering BIOS setup temporary disables watchdog operation regardless to current state,

1094 Hardware driver for the TCO timer built into the nVidia Hub family
1095 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
1096 watchdog timer that will reboot the machine after its second
1097 expiration. The expiration time can be configured with the
1098 "heartbeat" parameter.
1099
1100 On some motherboards the driver may fail to reset the chipset's
1101 NO_REBOOT flag which prevents the watchdog from rebooting the
1102 machine. If this is the case you will get a kernel message like
1103 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1122 This driver can be used with the watchdog timer found on some
1123 single board computers, namely the 6010 PII based computer.
1124 It may well work with other cards. It reads port 0x443 to enable
1125 and re-set the watchdog timer, and reads port 0x45 to disable
1126 the watchdog. If you have a card that behave in similar ways,
1127 you can probably make this driver work with your card as well.

1432 Hardware driver for OCTEON's on chip watchdog timer.
1433 Enables the watchdog for all cores running Linux. It
1434 installs a NMI handler and pokes the watchdog based on an
1435 interrupt. On first expiration of the watchdog, the
1436 interrupt handler pokes it. The second expiration causes an
1437 NMI that prints a message. The third expiration causes a
1438 global soft reset.
1439
1440 When userspace has /dev/watchdog open, no poking is done
1441 from the first interrupt, it is then only poked when the
1442 device is written.

1765 This is a driver for the Mixcom hardware watchdog cards. This
1766 watchdog simply watches your kernel to make sure it doesn't freeze,
1767 and if it does, it reboots your computer after a certain amount of
1768 time.

1779 If you have a WDT500P or WDT501P watchdog board, say Y here,
1780 otherwise N. It is not possible to probe for this board, which means
1781 that you have to inform the kernel about the IO port and IRQ that
1782 is needed (you can do this via the io and irq parameters)

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001815 If you have a PCI-WDT501 watchdog board then you can enable the
