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

1546 This driver is for a SoC level watchdog that exists on some
1547 Freescale PowerPC processors. So far this driver supports:

1581 range 0 63 if PPC_FSL_BOOK3E
1582 default 3 if !PPC_FSL_BOOK3E
1583 range 0 3 if !PPC_FSL_BOOK3E
1585 Select the default watchdog timer period to be used by the PowerPC
1586 Book-E watchdog driver. A watchdog "event" occurs when the bit
1587 position represented by this number transitions from zero to one.
1589 For Freescale Book-E processors, this is a number between 0 and 63.
1590 For other Book-E processors, this is a number between 0 and 3.
1592 The value can be overridden by the wdt_period command-line parameter.

1637 tristate "SuperH Watchdog"
1638 depends on SUPERH && (CPU_SH3 || CPU_SH4)
1639 select WATCHDOG_CORE
1641 This driver adds watchdog support for the integrated watchdog in the
1642 SuperH processors. If you have one of these processors and wish
1643 to have watchdog support enabled, say Y, otherwise say N.
1645 As a side note, saying Y here will automatically boost HZ to 1000
1646 so that the timer has a chance to clear the overflow counter. On
1647 slower systems (such as the SH-2 and SH-3) this will likely yield
1648 some performance issues. As such, the WDT should be avoided here
1649 unless it is absolutely necessary.
1651 To compile this driver as a module, choose M here: the
1652 module will be called shwdt.

1663 Sun Microsystems CompactPCI models CP1400 and CP1500.
1665 To compile this driver as a module, choose M here: the
1666 module will be called cpwatchdog.
1668 If you do not have a CompactPCI model CP1400 or CP1500, or
1669 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
1670 you should say N to this option.
1673 tristate "RIO Hardware Watchdog support"
1674 depends on SPARC64 && PCI
1676 Say Y here to support the hardware watchdog capability on Sun RIO
1677 machines. The watchdog timeout period is normally one minute but
1678 can be changed with a boot-time parameter.

1718 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1719 This card simply watches your kernel to make sure it doesn't freeze,
1720 and if it does, it reboots your computer after a certain amount of
1721 time. This driver is like the WDT501 driver but for different
1722 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1723 watchdog cards can be ordered from <http://www.berkprod.com/>.

1745 tristate "WDT Watchdog timer"
1748 If you have a WDT500P or WDT501P watchdog board, say Y here,
1749 otherwise N. It is not possible to probe for this board, which means
1750 that you have to inform the kernel about the IO port and IRQ that
1751 is needed (you can do this via the io and irq parameters)

1784 If you have a PCI-WDT501 watchdog board then you can enable the
1785 temperature sensor by setting the type parameter to 501.
1787 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
