✨ xe_pagefault_reset(9) ✨

okay so bestie, we're deep in the kernel API manual today — this one lives in section 9, the driver/kernel-API zone 🎀 and it's all about clearing out page fault drama on a GT. no cap, it's a tiny function but it does exactly one job and it does it slay.

---

🌸 NAME 🌸

xe_pagefault_reset — page fault reset for a GT 💅

---

🦋 SYNOPSIS 🦋

void xe_pagefault_reset (struct xe_device *xe , struct xe_gt *gt );

---

🎀 ARGUMENTS 🎀

• xe — the xe device instance, your main character struct 🫶
• gt — the GT that's getting reset, the one we're doing this whole thing for ✨

---

💖 DESCRIPTION 💖

So here's the vibe: you call this and it resets the Xe page fault state for a GT. literally what that means is — it squashes any pending faults on that GT. gone. deleted. not me clearing the queue bestie 😭🔥

think of it as the lil cleanup crew for a GT that's being reset, so no stale fault nonsense lingers around afterwards. iconic behavior, honestly 👑
