💖 VIAWD(4) 💖

okay bestie, this is the kernel interfaces manual page for viawd, and we're gonna get you fully caught up. no cap. 🫶

✨ NAME ✨

viawd — device driver for VIA south bridge watchdog timer 🐶

🌸 SYNOPSIS 🌸

So to compile this driver into the kernel, you put this line in your kernel configuration file:

device viawd

Or, alternate route, if you'd rather load the driver as a module at boot time, you drop this line into loader.conf(5):

viawd_load="YES"

Pick your lane, both slay. 💅

🦋 DESCRIPTION 🦋

The viawd driver provides watchdog(4) support for the watchdog interrupt timer that lives on VIA south bridge chipsets — specifically VT8251, CX700, VX800, VX855, and VX900. the range, we love her. 👑

The VIA south bridge has a built-in watchdog timer, and the way it works is: it can be enabled and disabled by your user's program, and you can set it between 1 to 1023 seconds. periodt.

And lowkey important: when the viawd driver gets unloaded while the watchdog is still running, it will reschedule the watchdog to 5 minutes. not me warning you about that, but like, I am. 😭
