7 bool "Watchdog Timer Support"
8 ---help---
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
e0845bf4 15 on-line as fast as possible after a lock-up. There's both a watchdog
1da177e4
LT
16 implementation entirely in software (which can sometimes fail to
17 reboot the machine) and a driver for hardware watchdog boards, which
18 are more robust and can also keep track of the temperature inside
e403149c
DH
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
1da177e4
LT
21
22 The watchdog is usually used together with the watchdog daemon
23 which is available from
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process
26 table is full.

34 ---help---

42 help
43 The default watchdog behaviour (which you get if you say N here) is
44 to stop the timer if the process managing it closes the file
45 /dev/watchdog. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
47 it has been started.

50 bool "Update boot-enabled watchdog until userspace takes over"
51 default y
52 help
53 The default watchdog behaviour (which you get if you say Y here) is
54 to ping watchdog devices that were enabled before the driver has
55 been loaded until control is taken over from userspace using the
56 /dev/watchdog file. If you say N here, the kernel will not update
57 the watchdog on its own. Thus if your userspace does not start fast
58 enough your device will reboot.

473 be built as a module by choosing M. The module will
474 be called iop_wdt.
475
476 Note: The IOP13XX watchdog does an Internal Bus Reset which will
477 affect both cores and the peripherals of the IOP. The ATU-X
478 and/or ATUe configuration registers will remain intact, but if
479 operating as an Root Complex and/or Central Resource, the PCI-X
480 and/or PCIe busses will also be reset. THIS IS A VERY BIG HAMMER.

937 This driver enables a watchdog capability built into the
938 CS5535/CS5536 companion chips for the AMD Geode GX and LX
939 processors. This watchdog watches your kernel to make sure
940 it doesn't freeze, and if it does, it reboots your computer after
941 a certain amount of time.

943 You can compile this driver directly into the kernel, or use
944 it as a module. The module will be called geodewdt.

966 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
967 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
968
969 Entering BIOS setup temporary disables watchdog operation regardless to current state,
970 so system will not be restarted while user in BIOS setup.
971
972 Once watchdog was enabled the system will be restarted every
973 "Watchdog Timer Value" period, so to prevent it user can restart or
974 disable the watchdog.

1806 As a side note, saying Y here will automatically boost HZ to 1000
1807 so that the timer has a chance to clear the overflow counter. On
1808 slower systems (such as the SH-2 and SH-3) this will likely yield
1809 some performance issues. As such, the WDT should be avoided here
1810 unless it is absolutely necessary.

1812 To compile this driver as a module, choose M here: the
1813 module will be called shwdt.
