viawd -- device driver for VIA south bridge watchdog timer
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device viawd
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
viawd_load="YES"
DESCRIPTION
The viawd driver provides watchdog(4) support for the watchdog interrupt timer present on VIA south bridge chipset (VT8251, CX700, VX800,
VX855, VX900).
The VIA south bridge have a built-in watchdog timer, which can be enabled and disabled by user's program and set between 1 to 1023 seconds.
The viawd driver when unloaded with running watchdog will reschedule the watchdog to 5 minutes.
