xe_tlb_inval_all(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xe_tlb_inval_all(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're in the kernel, and every single TLB out there needs to be told "girl, your cached translations are expired, let them GO." That's this function. It's xe_tlb_inval_all, and yes she's giving main character energy in xe_tlb_inval.c. 🎀

🌸 NAME 🌸

xe_tlb_inval_all — Issue a TLB invalidation for all TLBs. that's it. that's the whole vibe check. she invalidates. all of them. periodt. 💅

✨ SYNOPSIS ✨

int xe_tlb_inval_all (struct xe_tlb_inval *tlb_inval , struct
xe_tlb_inval_fence *fence );

like, two args, one int back. no cap, it's that simple. 🦋

🫶 ARGUMENTS 🫶

  • tlb_inval — the TLB invalidation client. your lil entry point into the whole invalidation situation, iykyk.
  • fence — the invalidation fence, and it will be signal on TLB invalidation completion. (yes, that's the original wording, she's quirky like that, we love her 😭) this is your "text me when you're done" of the kernel world.

💖 DESCRIPTION 💖

Issue a TLB invalidation for all TLBs. all of them. every last one. the whole group chat. 🔥

but here's the tea: completion of TLB is asynchronous, so it is not done the second this returns. nope. the caller can use the invalidation fence to wait for completion — that's literally what it's for, bestie. don't be out here assuming it's finished just because the function came back. 👑

⭐ RETURN ⭐

0 on success, negative error code on error. iconic behavior honestly. 🌈

🦋 SEE ALSO 🦋

that's the whole friend group right there, go say hi to all of them 💜

fr fr reminder: the fence is how you find out when it's actually done, because completion is asynchronous. don't skip the vibe check. 🧚

and that's a wrap! this page came to you live from ./drivers/gpu/drm/xe in the gorgeous month of October 2026, part of the Kernel API Manual. slay, go invalidate some TLBs responsibly 🍓👑💀
