ITWD(4)

💖 ITWD(4) 💖

okay bestie, gather round, because we're talking about itwd — the device driver for ITE Super I/O chips watchdog timer 🐶⏰ (yes it's a section 4 Kernel Interfaces Manual page, we love a kernel moment)

✨ NAME ✨

itwd — device driver for ITE Super I/O chips watchdog timer

like. that's the whole vibe. it's the driver, it's for the watchdog timer, it lives on ITE Super I/O chips. iconic. 💅

🎀 SYNOPSIS 🎀

so there's two ways to get this baby into your life, and you gotta pick one, no cap:

Option A — compile it straight into the kernel 🫶 drop these lines into your kernel configuration file:

device superio
device itwd

Option B — load it as a module at boot time 🌸 put this line in loader.conf(5):

itwd_load="YES"

either way you're eating good fr fr

🦋 DESCRIPTION 🦋

okay so the itwd driver is the one that provides watchdog(4) support for the watchdog timer that lives on these Super I/O chips. and when I say "these chips" I mean at least these, because the list is giving "we know these work, there may be more, don't @ me":

• IT8721F
• IT8728F
• IT8771F

the way that a watchdog timer just sits there watching… main character energy honestly 👑
