In linux kernel since version 2.6.36 (release Date: 2010-10-20)
Hardware driver for OCTEON's on chip watchdog timer.
Enables the watchdog for all cores running Linux. It
installs a NMI handler and pokes the watchdog based on an
interrupt. On first expiration of the watchdog, the
interrupt handler pokes it. The second expiration causes an
NMI that prints a message. The third expiration causes a
global soft reset.
When userspace has /dev/watchdog open, no poking is done
from the first interrupt, it is then only poked when the
device is written.
