💖 FTWD(4) — the Fintek F81803 watchdog timer, explained by your fave ✨

okay so bestie, gather round, because today we're talking about the ftwd driver — aka the Fintek F81803 watchdog timer. yes it's a kernel interfaces manual page, no it's not boring, literally stay with me 💅

🌸 NAME 🌸

ftwd — the Fintek F81803 watchdog timer. that's the whole vibe. a little timer in a chip that watches stuff. iconic behavior fr fr 🫶

✨ SYNOPSIS ✨

so there's two ways to get this driver into your life, and honestly both are valid.

🎀 option one: bake it into the kernel

to compile this driver into the kernel, you gotta place the following lines in your kernel configuration file:

device superio
device ftwd

like, both of them. superio first, then ftwd. don't skip the superio one, that's the whole support system, the bestie that makes it work 💜

🦋 option two: load it as a module

alternatively — and this is the lazy-girl route, no shame — to load the driver as a module at boot time, place the following line in loader.conf(5):

ftwd_load="YES"

that's it. one line. slay. ✨

🔥 DESCRIPTION 🔥

okay so here's the tea: the ftwd driver provides watchdog(4) support for the watchdog timer that lives inside the Fintek F81803 chip.

that's literally the whole description. it's a short one. quality over quantity, periodt. it does one thing and it does it well 👑
