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
e0845bf4 14 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
15 implementation entirely in software (which can sometimes fail to
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
e403149c

18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.

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.

34 The default watchdog behaviour (which you get if you say N here) is
35 to stop the timer if the process managing it closes the file
36 /dev/watchdog. It's always remotely possible that this process might
37 get killed. If you say Y here, the watchdog cannot be stopped once
38 it has been started.

474 will detect lockups and provide stack trace. Also, when an NMI
475 occurs this driver will make the necessary BIOS calls to log
476 the cause of the NMI. This is a driver that will only load on a
477 HP ProLiant system with a minimum of iLO2 support.

959 If you have a WDT500P or WDT501P watchdog board, say Y here,
960 otherwise N. It is not possible to probe for this board, which means
961 that you have to inform the kernel about the IO port and IRQ that
962 is needed (you can do this via the io and irq parameters)
963
964 To compile this driver as a module, choose M here: the
965 module will be called wdt.

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

1002 Saying Y here and creating a character special file /dev/temperature
1003 with major number 10 and minor number 131 ("man mknod") will give
1004 you a thermometer inside your computer: reading from
1005 /dev/temperature yields one byte, the temperature in degrees
1006 Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
1007 installed.
1008
1009 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1010 can do this via the tachometer parameter. Only do this if you have a
1011 fan tachometer actually set up.
