🌸 SYNOPSIS 🌸

ichwdt* at pci?

🎀 DESCRIPTION 🎀

The ichwdt driver supports the watchdog timer of the Intel 6300ESB I/O Controller Hub. that’s the whole vibe 🕰️

ichwdt provides the standard watchdog(4) interface and may be used with watchdogd(8). the watchdog timer can be configured via sysctl(8). slay ✨

Once the watchdog timer resets the CPU, the driver reports it on the next boot displaying the “reboot on timeout” message in the dmesg. literally shows up so you know what happened 😭🔥

bestie note: that message is the driver’s little receipt 🧾💖
