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

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.
62 config AT91RM9200_WATCHDOG
63 tristate "AT91RM9200 watchdog"

67 system when the timeout is reached.
70 tristate "DC21285 watchdog"
73 The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
74 here if you wish to use this. Alternatively say M to compile the
75 driver as a module, which will be called wdt285.
77 This driver does not work on all machines. In particular, early CATS
78 boards have hardware problems that will cause the machine to simply
79 lock up if the watchdog fires.

84 tristate "NetWinder WB83C977 watchdog"
85 depends on FOOTBRIDGE && ARCH_NETWINDER

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

779 If you do not have a CompactPCI model CP1400 or CP1500, or
780 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
781 you should say N to this option.
784 tristate "RIO Hardware Watchdog support"
785 depends on SPARC64 && PCI
787 Say Y here to support the hardware watchdog capability on Sun RIO
788 machines. The watchdog timeout period is normally one minute but
789 can be changed with a boot-time parameter.

804 This is the driver for the Berkshire Products ISA-PC Watchdog card.
805 This card simply watches your kernel to make sure it doesn't freeze,
806 and if it does, it reboots your computer after a certain amount of
807 time. This driver is like the WDT501 driver but for different
808 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
809 watchdog cards can be ordered from <http://www.berkprod.com/>.
811 To compile this driver as a module, choose M here: the
812 module will be called pcwd.
814 Most people will say N.

828 Most people will say N.
831 tristate "WDT Watchdog timer"
834 If you have a WDT500P or WDT501P watchdog board, say Y here,
835 otherwise N. It is not possible to probe for this board, which means
836 that you have to inform the kernel about the IO port and IRQ that
837 is needed (you can do this via the io and irq parameters)
839 To compile this driver as a module, choose M here: the
840 module will be called wdt.
843 bool "WDT501 features"
846 Saying Y here and creating a character special file /dev/temperature
847 with major number 10 and minor number 131 ("man mknod") will give
848 you a thermometer inside your computer: reading from
849 /dev/temperature yields one byte, the temperature in degrees
850 Fahrenheit. This works only if you have a WDT501P watchdog board
853 If you want to enable the Fan Tachometer on the WDT501P, then you
854 can do this via the tachometer parameter. Only do this if you have a
855 fan tachometer actually set up.
