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.

56 module will be called softdog.
58 config WM8350_WATCHDOG
59 tristate "WM8350 watchdog"

70 tristate "AT91RM9200 watchdog"
71 depends on ARCH_AT91RM9200
73 Watchdog timer embedded into AT91RM9200 chips. This will reboot your

743 tristate "Sibyte SoC hardware watchdog"
746 Watchdog driver for the built in watchdog hardware in Sibyte
747 SoC processors. There are apparently two watchdog timers
748 on such processors; this driver supports only the first one,
749 because currently Linux only supports exporting one watchdog

763 depends on CPU_TX39XX || CPU_TX49XX
765 Hardware driver for the built-in watchdog timer on TXx9 MIPS SoCs.

772 tristate "GE Fanuc Watchdog Timer"

779 depends on PPC_MPC52xx
782 tristate "MPC8xxx Platform Watchdog Timer"
783 depends on PPC_8xx || PPC_83xx || PPC_86xx
785 This driver is for a SoC level watchdog that exists on some
786 Freescale PowerPC processors. So far this driver supports:

821 will be called wdrtas.
826 tristate "z/VM Watchdog Timer"
829 IBM s/390 and zSeries machines running under z/VM 5.1 or later
830 provide a virtual watchdog timer to their guest that cause a
831 user define Control Program command to be executed after a

835 will be called vmwatchdog.
837 # SUPERH (sh + sh64) Architecture
840 tristate "SuperH Watchdog"
841 depends on SUPERH && (CPU_SH3 || CPU_SH4)
843 This driver adds watchdog support for the integrated watchdog in the
844 SuperH processors. If you have one of these processors and wish
845 to have watchdog support enabled, say Y, otherwise say N.
847 As a side note, saying Y here will automatically boost HZ to 1000
848 so that the timer has a chance to clear the overflow counter. On
849 slower systems (such as the SH-2 and SH-3) this will likely yield
850 some performance issues. As such, the WDT should be avoided here
851 unless it is absolutely necessary.
853 To compile this driver as a module, choose M here: the
854 module will be called shwdt.
857 bool "Allow mmap of SH WDT"
861 If you say Y here, user applications will be able to mmap the

869 tristate "CP1XXX Hardware Watchdog support"
870 depends on SPARC64 && PCI
872 This is the driver for the hardware watchdog timers present on
873 Sun Microsystems CompactPCI models CP1400 and CP1500.
875 To compile this driver as a module, choose M here: the
876 module will be called cpwatchdog.
878 If you do not have a CompactPCI model CP1400 or CP1500, or
879 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
880 you should say N to this option.
883 tristate "RIO Hardware Watchdog support"
884 depends on SPARC64 && PCI
886 Say Y here to support the hardware watchdog capability on Sun RIO
887 machines. The watchdog timeout period is normally one minute but
888 can be changed with a boot-time parameter.

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

911 module will be called pcwd.

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

939 module will be called wdt.

949 tristate "Berkshire Products PCI-PC Watchdog"
952 This is the driver for the Berkshire Products PCI-PC Watchdog card.
953 This card simply watches your kernel to make sure it doesn't freeze,
954 and if it does, it reboots your computer after a certain amount of
955 time. The card can also monitor the internal temperature of the PC.

964 tristate "PCI-WDT500/501 Watchdog timer"
967 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
969 To compile this driver as a module, choose M here: the
970 module will be called wdt_pci.
973 bool "PCI-WDT501 features"
976 Saying Y here and creating a character special file /dev/temperature
977 with major number 10 and minor number 131 ("man mknod") will give
978 you a thermometer inside your computer: reading from
979 /dev/temperature yields one byte, the temperature in degrees
980 Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
983 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
984 can do this via the tachometer parameter. Only do this if you have a
985 fan tachometer actually set up.
