xe_tlb_inval_batch_wait(9)

💅 xe_tlb_inval_batch_wait — like, the whole NAME section, bestie ✨

okay so this is from the Kernel API Manual, and the function is literally called xe_tlb_inval_batch_wait, and what it does is wait for all the fences in a TLB invalidation batch. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void xe_tlb_inval_batch_wait (struct xe_tlb_inval_batch *batch );

no cap, that's the whole signature. void in, void out, one pointer, zero drama. 💅

---

🦋 ARGUMENTS 🦋

• batch — the batch of TLB invalidation fences you're waiting on. that's your girl right there. she holds the fences, you hand her over, she gets waited on. periodt. 🫶

---

✨ DESCRIPTION ✨

so here's the tea: it waits for every fence in batch to signal. every single one. not some, not most — every. 🧚 and once they've all signalled, it resets batch so you can reuse it for a subsequent invalidation. iconic behaviour honestly, she cleans up after herself. 🔥

like, the way that it both waits and resets? main character energy fr fr. 😭
