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
44 to stop the timer if the process managing it closes the file

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

1569 default 3 if !PPC_FSL_BOOK3E
1570 range 0 3 if !PPC_FSL_BOOK3E
1572 Select the default watchdog timer period to be used by the PowerPC
1573 Book-E watchdog driver. A watchdog "event" occurs when the bit
1574 position represented by this number transitions from zero to one.
1576 For Freescale Book-E processors, this is a number between 0 and 63.
1577 For other Book-E processors, this is a number between 0 and 3.
1579 The value can be overridden by the wdt_period command-line parameter.

1625 depends on SUPERH && (CPU_SH3 || CPU_SH4)
1626 select WATCHDOG_CORE
1628 This driver adds watchdog support for the integrated watchdog in the
1629 SuperH processors. If you have one of these processors and wish
1630 to have watchdog support enabled, say Y, otherwise say N.
1632 As a side note, saying Y here will automatically boost HZ to 1000
1633 so that the timer has a chance to clear the overflow counter. On
1634 slower systems (such as the SH-2 and SH-3) this will likely yield
1635 some performance issues. As such, the WDT should be avoided here
1636 unless it is absolutely necessary.

1639 module will be called shwdt.

1655 If you do not have a CompactPCI model CP1400 or CP1500, or

1657 you should say N to this option.
1660 tristate "RIO Hardware Watchdog support"
1661 depends on SPARC64 && PCI
1663 Say Y here to support the hardware watchdog capability on Sun RIO
1664 machines. The watchdog timeout period is normally one minute but
1665 can be changed with a boot-time parameter.

1705 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1706 This card simply watches your kernel to make sure it doesn't freeze,
1707 and if it does, it reboots your computer after a certain amount of
1708 time. This driver is like the WDT501 driver but for different
1709 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1710 watchdog cards can be ordered from <http://www.berkprod.com/>.

1735 If you have a WDT500P or WDT501P watchdog board, say Y here,
1736 otherwise N. It is not possible to probe for this board, which means
1737 that you have to inform the kernel about the IO port and IRQ that
1738 is needed (you can do this via the io and irq parameters)

1772 temperature sensor by setting the type parameter to 501.
1774 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
