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

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

1547 tristate "CP1XXX Hardware Watchdog support"
1548 depends on SPARC64 && PCI
1550 This is the driver for the hardware watchdog timers present on
1551 Sun Microsystems CompactPCI models CP1400 and CP1500.
1553 To compile this driver as a module, choose M here: the
1554 module will be called cpwatchdog.
1556 If you do not have a CompactPCI model CP1400 or CP1500, or
1557 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
1558 you should say N to this option.
1561 tristate "RIO Hardware Watchdog support"
1562 depends on SPARC64 && PCI
1564 Say Y here to support the hardware watchdog capability on Sun RIO
1565 machines. The watchdog timeout period is normally one minute but
1566 can be changed with a boot-time parameter.
1568 # XTENSA Architecture
1573 tristate "Xen Watchdog support"
1576 Say Y here to support the hypervisor watchdog capability provided
1577 by Xen 4.0 and newer. The watchdog timeout period is normally one
1578 minute but can be changed with a boot-time parameter.

1592 tristate "Berkshire Products ISA-PC Watchdog"
1595 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1596 This card simply watches your kernel to make sure it doesn't freeze,
1597 and if it does, it reboots your computer after a certain amount of
1598 time. This driver is like the WDT501 driver but for different
1599 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1600 watchdog cards can be ordered from <http://www.berkprod.com/>.

1603 module will be called pcwd.
1605 Most people will say N.
1608 tristate "Mixcom Watchdog"
1611 This is a driver for the Mixcom hardware watchdog cards. This
1612 watchdog simply watches your kernel to make sure it doesn't freeze,
1613 and if it does, it reboots your computer after a certain amount of
1616 To compile this driver as a module, choose M here: the
1617 module will be called mixcomwd.
1619 Most people will say N.
1622 tristate "WDT Watchdog timer"
1625 If you have a WDT500P or WDT501P watchdog board, say Y here,
1626 otherwise N. It is not possible to probe for this board, which means
1627 that you have to inform the kernel about the IO port and IRQ that
1628 is needed (you can do this via the io and irq parameters)
1630 To compile this driver as a module, choose M here: the
1631 module will be called wdt.

1645 This card simply watches your kernel to make sure it doesn't freeze,
1646 and if it does, it reboots your computer after a certain amount of
1647 time. The card can also monitor the internal temperature of the PC.

1656 tristate "PCI-WDT500/501 Watchdog timer"
1659 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1661 If you have a PCI-WDT501 watchdog board then you can enable the
1662 temperature sensor by setting the type parameter to 501.
1664 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1665 can do this via the tachometer parameter. Only do this if you have a
1666 fan tachometer actually set up.
