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.:

16 reboot the machine) and a driver for hardware watchdog boards, which

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
25 table is full.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

675 ---help---
676 Hardware driver for the TCO timer built into the nVidia Hub family
677 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
678 watchdog timer that will reboot the machine after its second
679 expiration. The expiration time can be configured with the
680 "heartbeat" parameter.
681
682 On some motherboards the driver may fail to reset the chipset's
683 NO_REBOOT flag which prevents the watchdog from rebooting the
684 machine. If this is the case you will get a kernel message like
685 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

688 module will be called nv_tco.

704 This driver can be used with the watchdog timer found on some
705 single board computers, namely the 6010 PII based computer.
706 It may well work with other cards. It reads port 0x443 to enable
707 and re-set the watchdog timer, and reads port 0x45 to disable
708 the watchdog. If you have a card that behave in similar ways,
709 you can probably make this driver work with your card as well.
710
711 You can compile this driver directly into the kernel, or use
712 it as a module. The module will be called sbc60xxwdt.

1063 Freescale PowerPC processors. So far this driver supports:
Anton Vorontsov0d7b1012008-07-03 23:51:36 -07001064 - MPC8xx watchdogs

1140 This driver adds watchdog support for the integrated watchdog in the
1141 SuperH processors. If you have one of these processors and wish
1142 to have watchdog support enabled, say Y, otherwise say N.
1143
1144 As a side note, saying Y here will automatically boost HZ to 1000
1145 so that the timer has a chance to clear the overflow counter. On
1146 slower systems (such as the SH-2 and SH-3) this will likely yield
1147 some performance issues. As such, the WDT should be avoided here
1148 unless it is absolutely necessary.
