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

1540 position represented by this number transitions from zero to one.
1542 For Freescale Book-E processors, this is a number between 0 and 63.
1543 For other Book-E processors, this is a number between 0 and 3.
1545 The value can be overridden by the wdt_period command-line parameter.

1591 depends on SUPERH && (CPU_SH3 || CPU_SH4)
1592 select WATCHDOG_CORE
1594 This driver adds watchdog support for the integrated watchdog in the
1595 SuperH processors. If you have one of these processors and wish
1596 to have watchdog support enabled, say Y, otherwise say N.
1598 As a side note, saying Y here will automatically boost HZ to 1000
1599 so that the timer has a chance to clear the overflow counter. On
1600 slower systems (such as the SH-2 and SH-3) this will likely yield
1601 some performance issues. As such, the WDT should be avoided here
1602 unless it is absolutely necessary.
1604 To compile this driver as a module, choose M here: the
1605 module will be called shwdt.

1616 Sun Microsystems CompactPCI models CP1400 and CP1500.
1618 To compile this driver as a module, choose M here: the
1619 module will be called cpwatchdog.
1621 If you do not have a CompactPCI model CP1400 or CP1500, or
1622 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
1623 you should say N to this option.
1626 tristate "RIO Hardware Watchdog support"
1627 depends on SPARC64 && PCI
1629 Say Y here to support the hardware watchdog capability on Sun RIO
1630 machines. The watchdog timeout period is normally one minute but
1631 can be changed with a boot-time parameter.

1642 be called sun4v_wdt.

1671 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1672 This card simply watches your kernel to make sure it doesn't freeze,
1673 and if it does, it reboots your computer after a certain amount of
1674 time. This driver is like the WDT501 driver but for different
1675 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1676 watchdog cards can be ordered from <http://www.berkprod.com/>.

1701 If you have a WDT500P or WDT501P watchdog board, say Y here,
1702 otherwise N. It is not possible to probe for this board, which means
1703 that you have to inform the kernel about the IO port and IRQ that
1704 is needed (you can do this via the io and irq parameters)

1737 If you have a PCI-WDT501 watchdog board then you can enable the
1738 temperature sensor by setting the type parameter to 501.
1740 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
