6 bool "Watchdog Timer Support"
8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This
13 could be useful for a networked machine that needs to come back
14 on-line as fast as possible after a lock-up. There's both a watchdog
15 implementation entirely in software (which can sometimes fail to
16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
31 config WATCHDOG_NOWAYOUT
32 bool "Disable watchdog shutdown on close"
34 The default watchdog behaviour (which you get if you say N here) is
35 to stop the timer if the process managing it closes the file
36 /dev/watchdog. It's always remotely possible that this process might
37 get killed. If you say Y here, the watchdog cannot be stopped once

49 tristate "Software watchdog"
51 A software monitoring watchdog. This will fail to reboot your system
52 from some situations that the hardware watchdog will recover
53 from. Equally it's a lot cheaper to install.
55 To compile this driver as a module, choose M here: the
56 module will be called softdog.
58 config WM831X_WATCHDOG
59 tristate "WM831x watchdog"

77 tristate "AT91RM9200 watchdog"

94 The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
95 here if you wish to use this. Alternatively say M to compile the
96 driver as a module, which will be called wdt285.
98 This driver does not work on all machines. In particular, early CATS

100 lock up if the watchdog fires.

106 depends on FOOTBRIDGE && ARCH_NETWINDER

135 which doesn't reset any peripherals. There are circumstances
136 where the watchdog will fail to reset the board correctly

732 If you are using a ZF Micro MachZ processor, say Y here, otherwise
733 N. This is the driver for the watchdog timer built-in on that
734 processor using ZF-Logic interface. This watchdog simply watches
735 your kernel to make sure it doesn't freeze, and if it does, it
736 reboots your computer after a certain amount of time.

739 module will be called machzwd.
741 config SBC_EPX_C3_WATCHDOG
742 tristate "Winsystems SBC EPX-C3 watchdog"
745 This is the driver for the built-in watchdog timer on the EPX-C3
746 Single-board computer made by Winsystems, Inc.
748 *Note*: This hardware watchdog is not probeable and thus there
749 is no way to know if writing to its IO address will corrupt
750 your system or have any real effect. The only way to be sure
751 that this driver does what you want is to make sure you
752 are running it on an EPX-C3 from Winsystems with the watchdog
753 timer at IO address 0x1ee and 0x1ef. It will write to both those
754 IO ports. Basically, the assumption is made that if you compile
755 this driver into your kernel and/or load it as a module, that you
756 know what you are doing and that you are in fact running on an

813 depends on CPU_RM9000

819 module will be called rm9k_wdt.
822 tristate "Sibyte SoC hardware watchdog"
825 Watchdog driver for the built in watchdog hardware in Sibyte
826 SoC processors. There are apparently two watchdog timers
827 on such processors; this driver supports only the first one,

916 # SUPERH (sh + sh64) Architecture
919 tristate "SuperH Watchdog"
920 depends on SUPERH && (CPU_SH3 || CPU_SH4)
922 This driver adds watchdog support for the integrated watchdog in the
923 SuperH processors. If you have one of these processors and wish
924 to have watchdog support enabled, say Y, otherwise say N.
926 As a side note, saying Y here will automatically boost HZ to 1000
927 so that the timer has a chance to clear the overflow counter. On
928 slower systems (such as the SH-2 and SH-3) this will likely yield
929 some performance issues. As such, the WDT should be avoided here
930 unless it is absolutely necessary.
932 To compile this driver as a module, choose M here: the
933 module will be called shwdt.

952 Sun Microsystems CompactPCI models CP1400 and CP1500.
954 To compile this driver as a module, choose M here: the

963 depends on SPARC64 && PCI
965 Say Y here to support the hardware watchdog capability on Sun RIO
966 machines. The watchdog timeout period is normally one minute but

1012 If you have a WDT500P or WDT501P watchdog board, say Y here,

1014 that you have to inform the kernel about the IO port and IRQ that
1015 is needed (you can do this via the io and irq parameters)
