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

1546 tristate "RTAS watchdog"
1549 This driver adds watchdog support for the RTAS watchdog.
1551 To compile this driver as a module, choose M here. The module
1552 will be called wdrtas.

1559 select WATCHDOG_CORE
1561 IBM s/390 and zSeries machines running under z/VM 5.1 or later
1562 provide a virtual watchdog timer to their guest that cause a
1563 user define Control Program command to be executed after a
1565 LPAR provides a very similar interface. This driver handles
1568 To compile this driver as a module, choose M here. The module
1569 will be called diag288_wdt.
1571 # SUPERH (sh + sh64) Architecture
1574 tristate "SuperH Watchdog"
1575 depends on SUPERH && (CPU_SH3 || CPU_SH4)
1576 select WATCHDOG_CORE
1578 This driver adds watchdog support for the integrated watchdog in the
1579 SuperH processors. If you have one of these processors and wish
1580 to have watchdog support enabled, say Y, otherwise say N.
1582 As a side note, saying Y here will automatically boost HZ to 1000
1583 so that the timer has a chance to clear the overflow counter. On
1584 slower systems (such as the SH-2 and SH-3) this will likely yield
1585 some performance issues. As such, the WDT should be avoided here
1586 unless it is absolutely necessary.
1588 To compile this driver as a module, choose M here: the
1589 module will be called shwdt.

1593 # SPARC64 Architecture
1595 config WATCHDOG_CP1XXX
1596 tristate "CP1XXX Hardware Watchdog support"
1597 depends on SPARC64 && PCI
1599 This is the driver for the hardware watchdog timers present on
1600 Sun Microsystems CompactPCI models CP1400 and CP1500.
1602 To compile this driver as a module, choose M here: the
1603 module will be called cpwatchdog.
1605 If you do not have a CompactPCI model CP1400 or CP1500, or
1606 another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
1607 you should say N to this option.
1610 tristate "RIO Hardware Watchdog support"
1611 depends on SPARC64 && PCI
1613 Say Y here to support the hardware watchdog capability on Sun RIO
1614 machines. The watchdog timeout period is normally one minute but
1615 can be changed with a boot-time parameter.
1617 # XTENSA Architecture
1622 tristate "Xen Watchdog support"
1625 Say Y here to support the hypervisor watchdog capability provided
1626 by Xen 4.0 and newer. The watchdog timeout period is normally one
1627 minute but can be changed with a boot-time parameter.

1641 tristate "Berkshire Products ISA-PC Watchdog"
1644 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1645 This card simply watches your kernel to make sure it doesn't freeze,
1646 and if it does, it reboots your computer after a certain amount of
1647 time. This driver is like the WDT501 driver but for different
1648 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1649 watchdog cards can be ordered from <http://www.berkprod.com/>.

1652 module will be called pcwd.

1660 This is a driver for the Mixcom hardware watchdog cards. This
1661 watchdog simply watches your kernel to make sure it doesn't freeze,
1662 and if it does, it reboots your computer after a certain amount of

1666 module will be called mixcomwd.
1668 Most people will say N.
1671 tristate "WDT Watchdog timer"
1674 If you have a WDT500P or WDT501P watchdog board, say Y here,
1675 otherwise N. It is not possible to probe for this board, which means
1676 that you have to inform the kernel about the IO port and IRQ that
1677 is needed (you can do this via the io and irq parameters)
1679 To compile this driver as a module, choose M here: the
1680 module will be called wdt.

1690 tristate "Berkshire Products PCI-PC Watchdog"
1693 This is the driver for the Berkshire Products PCI-PC Watchdog card.
1694 This card simply watches your kernel to make sure it doesn't freeze,
1695 and if it does, it reboots your computer after a certain amount of
1696 time. The card can also monitor the internal temperature of the PC.
1697 More info is available at <http://www.berkprod.com/pci_pc_watchdog.htm>.
1699 To compile this driver as a module, choose M here: the
1700 module will be called pcwd_pci.
1702 Most people will say N.
1705 tristate "PCI-WDT500/501 Watchdog timer"
1708 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1710 If you have a PCI-WDT501 watchdog board then you can enable the
1711 temperature sensor by setting the type parameter to 501.
1713 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1714 can do this via the tachometer parameter. Only do this if you have a
1715 fan tachometer actually set up.

1718 module will be called wdt_pci.
