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

88 here if you wish to use this. Alternatively say M to compile the
89 driver as a module, which will be called wdt285.

99 depends on FOOTBRIDGE && ARCH_NETWINDER

740 will reboot the machine after a 100 seconds timer expired.
743 tristate "PNX833x Hardware Watchdog"
744 depends on SOC_PNX8335
746 Hardware driver for the PNX833x's watchdog. This is a
747 watchdog timer that will reboot the machine after a programable
748 timer has expired and no process has written to /dev/watchdog during
752 tristate "RM9000/GPI hardware watchdog"
753 depends on CPU_RM9000
755 Watchdog implementation using the GPI hardware found on
756 PMC-Sierra RM9xxx CPUs.
758 To compile this driver as a module, choose M here: the
759 module will be called rm9k_wdt.
762 tristate "Sibyte SoC hardware watchdog"
765 Watchdog driver for the built in watchdog hardware in Sibyte
766 SoC processors. There are apparently two watchdog timers
767 on such processors; this driver supports only the first one,
768 because currently Linux only supports exporting one watchdog
771 To compile this driver as a loadable module, choose M here.
772 The module will be called sb_wdog.
775 tristate "TI AR7 Watchdog Timer"
778 Hardware driver for the TI AR7 Watchdog Timer.

798 depends on PPC_MPC52xx
801 tristate "MPC8xxx Platform Watchdog Timer"
802 depends on PPC_8xx || PPC_83xx || PPC_86xx
804 This driver is for a SoC level watchdog that exists on some
805 Freescale PowerPC processors. So far this driver supports:
810 For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.
813 tristate "MV64X60 (Marvell Discovery) Watchdog Timer"
817 tristate "PIKA FPGA Watchdog"
821 This enables the watchdog in the PIKA FPGA. Currently used on

837 This driver adds watchdog support for the RTAS watchdog.
839 To compile this driver as a module, choose M here. The module
840 will be called wdrtas.
845 tristate "z/VM Watchdog Timer"
848 IBM s/390 and zSeries machines running under z/VM 5.1 or later
849 provide a virtual watchdog timer to their guest that cause a
850 user define Control Program command to be executed after a
853 To compile this driver as a module, choose M here. The module
854 will be called vmwatchdog.
856 # SUPERH (sh + sh64) Architecture
859 tristate "SuperH Watchdog"
860 depends on SUPERH && (CPU_SH3 || CPU_SH4)
862 This driver adds watchdog support for the integrated watchdog in the
863 SuperH processors. If you have one of these processors and wish
864 to have watchdog support enabled, say Y, otherwise say N.
866 As a side note, saying Y here will automatically boost HZ to 1000
867 so that the timer has a chance to clear the overflow counter. On
868 slower systems (such as the SH-2 and SH-3) this will likely yield
869 some performance issues. As such, the WDT should be avoided here
870 unless it is absolutely necessary.
872 To compile this driver as a module, choose M here: the
873 module will be called shwdt.
876 bool "Allow mmap of SH WDT"
880 If you say Y here, user applications will be able to mmap the

888 tristate "CP1XXX Hardware Watchdog support"
889 depends on SPARC64 && PCI
891 This is the driver for the hardware watchdog timers present on
892 Sun Microsystems CompactPCI models CP1400 and CP1500.
894 To compile this driver as a module, choose M here: the
895 module will be called cpwatchdog.
897 If you do not have a CompactPCI model CP1400 or CP1500, or
898 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
899 you should say N to this option.
902 tristate "RIO Hardware Watchdog support"
903 depends on SPARC64 && PCI
905 Say Y here to support the hardware watchdog capability on Sun RIO
906 machines. The watchdog timeout period is normally one minute but
907 can be changed with a boot-time parameter.

919 tristate "Berkshire Products ISA-PC Watchdog"
922 This is the driver for the Berkshire Products ISA-PC Watchdog card.
923 This card simply watches your kernel to make sure it doesn't freeze,
924 and if it does, it reboots your computer after a certain amount of
925 time. This driver is like the WDT501 driver but for different
926 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
927 watchdog cards can be ordered from <http://www.berkprod.com/>.
929 To compile this driver as a module, choose M here: the
930 module will be called pcwd.
932 Most people will say N.

939 watchdog simply watches your kernel to make sure it doesn't freeze,

949 tristate "WDT Watchdog timer"
952 If you have a WDT500P or WDT501P watchdog board, say Y here,
953 otherwise N. It is not possible to probe for this board, which means
954 that you have to inform the kernel about the IO port and IRQ that
955 is needed (you can do this via the io and irq parameters)
957 To compile this driver as a module, choose M here: the
958 module will be called wdt.

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

983 tristate "PCI-WDT500/501 Watchdog timer"
986 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
988 To compile this driver as a module, choose M here: the
989 module will be called wdt_pci.
992 bool "PCI-WDT501 features"
995 Saying Y here and creating a character special file /dev/temperature
996 with major number 10 and minor number 131 ("man mknod") will give
997 you a thermometer inside your computer: reading from
998 /dev/temperature yields one byte, the temperature in degrees
999 Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
1002 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1003 can do this via the tachometer parameter. Only do this if you have a
1004 fan tachometer actually set up.
