🦋 xe_tlb_inval_idle(9) — the Kernel API Manual bestie ✨

okay so real quick, this page lives in the Kernel API Manual and it's all about xe_tlb_inval_idle — literally the vibe check for whether your TLB invalidation client is chillin' or not 💅

---

🌸 NAME 🌸

xe_tlb_inval_idle — Initialize TLB invalidation is idle 🎀 (yes that's the official wording bestie, I don't make the rules)

---

✨ SYNOPSIS ✨

bool xe_tlb_inval_idle (struct xe_tlb_inval *tlb_inval );

---

🫶 ARGUMENTS 🫶

• tlb_inval — the TLB invalidation client, aka the main character of this function 👑

---

💖 DESCRIPTION 💖

So what this does is it checks the TLB invalidation seqno to figure out if things are idle — and by idle we mean no TLB invalidations are in flight at all, like nothing pending, the group chat is empty, no cap 🌈

It's expected to be called in the backend after the fence has been added to the pending list, and it takes that into account (fr fr, the ordering matters, don't come for me) ⭐

---

🔥 RETURN 🔥

• True — if the TLB invalidation client is idle 🎉 slay
• False — otherwise 🙈
