xe_tlb_inval_ggtt(9)

💅 xe_tlb_inval_ggtt 💅

okay so bestie, welcome to the Kernel API Manual</kbd>... sorry, the Kernel API Manual entry for xe_tlb_inval_ggtt(9) — literally the glow-up guide to poking the GGTT's TLB. she's a function, she's in the xe driver, and she's here to serve. ✨

---

✨ SYNOPSIS ✨

int xe_tlb_inval_ggtt (struct xe_tlb_inval *tlb_inval );

like, that's it. one arg. she's lowkey low-maintenance. 🎀

---

🌸 ARGUMENTS 🌸

• tlb_inval — the TLB invalidation client 🫶. that's your ticket, your little backstage pass to the TLB invalidation world. hand her over and let her cook.

---

🦋 DESCRIPTION 🦋

okay so the whole vibe here: this function issues a TLB invalidation for the GGTT. that's the assignment. no cap, that's literally the job. 🧚

but here's the tea — completion of TLB is asynchronous, so it does not sit there waiting around like a clingy ex. instead, the caller can use the invalidation fence to wait for completion. it's giving "drop it off and go live your life, then come back when you actually need the result." main character energy for the caller, fr fr. 💅

👑 RETURN 👑

• 0 — success, slay, we ate. 🌈
• a negative error code — on error. 😭 yeah, that happened.

🌟 as always, keep your asynchronous completions and your sanity close, bestie — and don't forget the fence. ⭐

and that's a wrap, diva. this beauty lives in ./drivers/gpu/drm/xe and the version/date stamp on her is October 2026. mwah 💋🦋💜
