Linus Torvalds1da177e2005-04-16 15:20:36 -070010 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:

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

1736 interrupt. On first expiration of the watchdog, the
1737 interrupt handler pokes it. The second expiration causes an
1738 NMI that prints a message. The third expiration causes a
1739 global soft reset.

1970 to have watchdog support enabled, say Y, otherwise say N.
1971
1972 As a side note, saying Y here will automatically boost HZ to 1000
1973 so that the timer has a chance to clear the overflow counter. On
1974 slower systems (such as the SH-2 and SH-3) this will likely yield
1975 some performance issues. As such, the WDT should be avoided here
