7 bool "Watchdog Timer Support"
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
15 on-line as fast as possible after a lock-up. There's both a watchdog
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
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
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

40 config WATCHDOG_NOWAYOUT
41 bool "Disable watchdog shutdown on close"
43 The default watchdog behaviour (which you get if you say N here) is

46 get killed. If you say Y here, the watchdog cannot be stopped once

782 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
783 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
785 Entering BIOS setup temporary disables watchdog operation regardless to current state,
786 so system will not be restarted while user in BIOS setup.
788 Once watchdog was enabled the system will be restarted every
789 "Watchdog Timer Value" period, so to prevent it user can restart or
790 disable the watchdog.

1549 will be called diag288_wdt.
1551 # SUPERH (sh + sh64) Architecture
1554 tristate "SuperH Watchdog"
1555 depends on SUPERH && (CPU_SH3 || CPU_SH4)
1556 select WATCHDOG_CORE
1558 This driver adds watchdog support for the integrated watchdog in the
1559 SuperH processors. If you have one of these processors and wish
1560 to have watchdog support enabled, say Y, otherwise say N.
1562 As a side note, saying Y here will automatically boost HZ to 1000
1563 so that the timer has a chance to clear the overflow counter. On
1564 slower systems (such as the SH-2 and SH-3) this will likely yield
1565 some performance issues. As such, the WDT should be avoided here
1566 unless it is absolutely necessary.

1569 module will be called shwdt.

1575 config WATCHDOG_CP1XXX
1576 tristate "CP1XXX Hardware Watchdog support"
1577 depends on SPARC64 && PCI
1579 This is the driver for the hardware watchdog timers present on
1580 Sun Microsystems CompactPCI models CP1400 and CP1500.
1582 To compile this driver as a module, choose M here: the
1583 module will be called cpwatchdog.
1585 If you do not have a CompactPCI model CP1400 or CP1500, or
1586 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
1587 you should say N to this option.
1590 tristate "RIO Hardware Watchdog support"
1591 depends on SPARC64 && PCI
1593 Say Y here to support the hardware watchdog capability on Sun RIO
1594 machines. The watchdog timeout period is normally one minute but
1595 can be changed with a boot-time parameter.
1597 # XTENSA Architecture
1602 tristate "Xen Watchdog support"
1605 Say Y here to support the hypervisor watchdog capability provided
1606 by Xen 4.0 and newer. The watchdog timeout period is normally one
1607 minute but can be changed with a boot-time parameter.

1624 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1625 This card simply watches your kernel to make sure it doesn't freeze,
1626 and if it does, it reboots your computer after a certain amount of
1627 time. This driver is like the WDT501 driver but for different
1628 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1629 watchdog cards can be ordered from <http://www.berkprod.com/>.

1632 module will be called pcwd.

1641 watchdog simply watches your kernel to make sure it doesn't freeze,

1651 tristate "WDT Watchdog timer"
1654 If you have a WDT500P or WDT501P watchdog board, say Y here,
1655 otherwise N. It is not possible to probe for this board, which means
1656 that you have to inform the kernel about the IO port and IRQ that
1657 is needed (you can do this via the io and irq parameters)

1660 module will be called wdt.

1673 This is the driver for the Berkshire Products PCI-PC Watchdog card.
1674 This card simply watches your kernel to make sure it doesn't freeze,
1675 and if it does, it reboots your computer after a certain amount of
1676 time. The card can also monitor the internal temperature of the PC.

1680 module will be called pcwd_pci.
1682 Most people will say N.
1685 tristate "PCI-WDT500/501 Watchdog timer"
1688 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1690 If you have a PCI-WDT501 watchdog board then you can enable the
1691 temperature sensor by setting the type parameter to 501.
1693 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1694 can do this via the tachometer parameter. Only do this if you have a
1695 fan tachometer actually set up.
