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

17 reboot the machine) and a driver for hardware watchdog boards, which

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

843 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
844
845 Entering BIOS setup temporary disables watchdog operation regardless to current state,
846 so system will not be restarted while user in BIOS setup.
847
848 Once watchdog was enabled the system will be restarted every

1079 depends on X86 && PCI
1080 ---help---
1081 Hardware driver for the TCO timer built into the nVidia Hub family
1082 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
1083 watchdog timer that will reboot the machine after its second
1084 expiration. The expiration time can be configured with the
1085 "heartbeat" parameter.
1086
1087 On some motherboards the driver may fail to reset the chipset's
1088 NO_REBOOT flag which prevents the watchdog from rebooting the
1089 machine. If this is the case you will get a kernel message like
1090 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

1109 This driver can be used with the watchdog timer found on some
1110 single board computers, namely the 6010 PII based computer.
1111 It may well work with other cards. It reads port 0x443 to enable
1112 and re-set the watchdog timer, and reads port 0x45 to disable
1113 the watchdog. If you have a card that behave in similar ways,
1114 you can probably make this driver work with your card as well.
1115
1116 You can compile this driver directly into the kernel, or use
1117 it as a module. The module will be called sbc60xxwdt.

1419 Hardware driver for OCTEON's on chip watchdog timer.
1420 Enables the watchdog for all cores running Linux. It
1421 installs a NMI handler and pokes the watchdog based on an
1422 interrupt. On first expiration of the watchdog, the
1423 interrupt handler pokes it. The second expiration causes an
1424 NMI that prints a message. The third expiration causes a
1425 global soft reset.
1426
1427 When userspace has /dev/watchdog open, no poking is done
1428 from the first interrupt, it is then only poked when the
1429 device is written.

1766 If you have a WDT500P or WDT501P watchdog board, say Y here,
1767 otherwise N. It is not possible to probe for this board, which means
1768 that you have to inform the kernel about the IO port and IRQ that
1769 is needed (you can do this via the io and irq parameters)
1770
1771 To compile this driver as a module, choose M here: the
1772 module will be called wdt.

1785 This is the driver for the Berkshire Products PCI-PC Watchdog card.
1786 This card simply watches your kernel to make sure it doesn't freeze,
1787 and if it does, it reboots your computer after a certain amount of
1788 time. The card can also monitor the internal temperature of the PC.

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001802 If you have a PCI-WDT501 watchdog board then you can enable the
1803 temperature sensor by setting the type parameter to 501.

1805 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1806 can do this via the tachometer parameter. Only do this if you have a
1807 fan tachometer actually set up.
