23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process

372 ARM SBSA Generic Watchdog has two stage timeouts:
373 the first signal (WS0) is for alerting the system by interrupt,
374 the second one (WS1) is a real hardware reset.
375 More details: ARM DEN0029B - Server Base System Architecture (SBSA)
376
377 This driver can operate ARM SBSA Generic Watchdog as a single stage
378 or a two stages watchdog, it depends on the module parameter "action".
379
380 Note: the maximum timeout in the two stages mode is half of that in
381 the single stage mode.

1136 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
1137 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
1138
1139 Entering BIOS setup temporary disables watchdog operation regardless to current state,
1140 so system will not be restarted while user in BIOS setup.
1141
1142 Once watchdog was enabled the system will be restarted every

1407 This driver can be used with the watchdog timer found on some
1408 single board computers, namely the 6010 PII based computer.
1409 It may well work with other cards. It reads port 0x443 to enable
1410 and re-set the watchdog timer, and reads port 0x45 to disable
1411 the watchdog. If you have a card that behave in similar ways,
1412 you can probably make this driver work with your card as well.

1745 interrupt. On first expiration of the watchdog, the
1746 interrupt handler pokes it. The second expiration causes an

1995 so that the timer has a chance to clear the overflow counter. On
1996 slower systems (such as the SH-2 and SH-3) this will likely yield
