AMDSBWD(4)

💖 AMDSBWD — the AMD southbridge watchdog timer driver, bestie edition 💖

okay so. this is the manual page for amdsbwd, a kernel interface thing, and honestly? she's niche but she's important. if you're here it's because you want your machine to have a watchdog on an AMD chipset and you want to know exactly how. no gatekeeping, let's get into it 🫶

✨ NAME ✨

amdsbwd — the device driver for the AMD southbridge watchdog timers 🐶⏰

🌸 SYNOPSIS 🌸

so to compile this driver into the kernel, you literally just drop this line into your kernel configuration file:

device amdsbwd

OR, if you'd rather load the driver as a module at boot time (valid! iconic! also fine!), you put this line in loader.conf(5):

amdsbwd_load="YES"

pick your fighter, both slay 💅

🎀 DESCRIPTION 🎀

the amdsbwd driver provides watchdog(4) support for the watchdog timers that are present on the supported chipsets. that's the whole vibe. that's what she does. ✨

👑 HARDWARE 👑

the amdsbwd driver supports the following chipsets — like, this is the guest list, no plus-ones:

• 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

if your chipset is on this list you're in your main character era, if it's not… 🙈
