💖 ACPIWDRT(4) 💖

okay so real talk, this is a page from the Kernel Interfaces Manual and it's all about acpiwdrt — like, the ACPI Watchdog Timer situation. buckle up bestie, it's a short one but it's iconic 💅

✨ NAME ✨

acpiwdrt — the ACPI Watchdog Timer (WDRT). that's it, that's the name, she's serving exactly what it says on the label 🎀

---

🌸 SYNOPSIS 🌸

acpiwdrt* at acpi?

that's the whole config line, no cap. she attaches at acpi? — yes the question mark is literally part of it, don't come for her 🦋

---

💫 DESCRIPTION 💫

so what does the acpiwdrt driver actually do? she provides support for watchdog timers that are specified in a so-called ACPI watchdog resource table (WDRT for short). the way that ACPI just hands you a whole table of watchdog info and this driver is like "say less, i got her" 😭🔥

and here's the part you actually need: the acpiwdrt watchdog timer is configurable via the wdogctl(8) utility. that's your remote control, bestie — go tweak the timer there, not here 🫶
