💅 AMDSBWD(4) — the amdsbwd page, bestie edition

okay so welcome to AMDSBWD(4), a page from the Kernel Interfaces Manual, and honestly? it's giving "small driver, big responsibility." sit down, grab a lil snack 🍓, and let me tell you about the AMD southbridge watchdog timers. no cap, this one's short but it matters.

✨ NAME ✨

amdsbwd — the device driver for the AMD southbridge watchdog timers 🐕🦺 like, yes, that's literally its whole job and it does it slayfully.

🎀 SYNOPSIS 🎀

so there's two ways to get this baby into your life, and both are iconic in their own way.

Option 1: bake it right into the kernel. add this line to your kernel configuration file:

device amdsbwd

Option 2: load it as a module at boot time. add this line to loader.conf(5):

amdsbwd_load="YES"

choose your fighter 💅 both work, both are valid, no wrong answers here.

🌸 DESCRIPTION 🌸

the amdsbwd driver provides watchdog(4) support for the watchdog timers that are present on the supported chipsets. that's it. that's the whole vibe. it finds the watchdog timer, it makes it work, it goes home. main character energy honestly 💖

🦋 HARDWARE 🦋

here's the guest list — the chipsets this driver supports are, and I quote, these:

  • AMD SB600/7x0/8x0/9x0 southbridges
  • AMD Axx/Hudson/Bolton FCHs
  • AMD FCHs integrated into Family 15h Models 60h-6Fh, 70h-7Fh Processors
  • AMD FCHs integrated into Family 16h Models 00h-0Fh, 30h-3Fh Processors
