💅 intel_gt_reset(9) — reset chip after a hang

okay so bestie, this page comes straight from the Kernel API Manual, and today’s main character is intel_gt_reset ✨ it’s literally giving “reset chip after a hang” energy, and honestly? iconic. no cap.

🌸 NAME 🌸

intel_gt_reset - reset chip after a hang 🫶

✨ SYNOPSIS ✨

here’s the exact signature, bestie — keep it character-for-character or the compiler will side-eye you 🙈

void intel_gt_reset (struct intel_gt *gt , intel_engine_mask_t
stalled_mask , const char *reason );

🎀 ARGUMENTS 🎀

• gt — the #intel_gt to reset 💅 yes, that exact #intel_gt vibe.
• stalled_mask — mask of the stalled engines with the guilty requests 😭 so you know which engines are being messy.
• reason — user error message for why we are resetting 📝 like a little note for the group chat.

🔥 DESCRIPTION 🔥

so intel_gt_reset resets the chip. useful if a hang is detected. on failure it marks the device as wedged — not the cute kind of wedged, the “this thing is stuck” kind 💀.

the procedure is fairly simple:

• reset the chip using the reset reg
• re-init context state
• re-init hardware status page
• re-init ring buffer
• re-init interrupt state
• re-init display

periodt. that’s the whole glow-up sequence 🌈
