7 ---help---
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
DH
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
20
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 The TCO (Total Cost of Ownership) timer is a watchdog timer
475 that will reboot the machine after its second expiration. The
476 expiration time can be configured with the "heartbeat" parameter.
477
478 On some motherboards the driver may fail to reset the chipset's
479 NO_REBOOT flag which prevents the watchdog from rebooting the
480 machine. If this is the case you will get a kernel message like

951 This is the driver for the hardware watchdog timers present on
952 Sun Microsystems CompactPCI models CP1400 and CP1500.
953
954 To compile this driver as a module, choose M here: the
955 module will be called cpwatchdog.
956
957 If you do not have a CompactPCI model CP1400 or CP1500, or
958 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
959 you should say N to this option.

966 machines. The watchdog timeout period is normally one minute but
967 can be changed with a boot-time parameter.

982 This is the driver for the Berkshire Products ISA-PC Watchdog card.
983 This card simply watches your kernel to make sure it doesn't freeze,
984 and if it does, it reboots your computer after a certain amount of
985 time. This driver is like the WDT501 driver but for different
986 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
987 watchdog cards can be ordered from <http://www.berkprod.com/>.

1012 If you have a WDT500P or WDT501P watchdog board, say Y here,
1013 otherwise N. It is not possible to probe for this board, which means
1014 that you have to inform the kernel about the IO port and IRQ that
1015 is needed (you can do this via the io and irq parameters)
