💅 xe_exec_queu...st_fence_set — Kernel API Manual ✨

okay so bestie, welcome to the kernel API manual for xe_exec_queu...st_fence_set(9) 💖 yes the title is truncated, no that's not a typo, that's just how the manpage gods roll, iykyk 🎀

---

🌸 NAME 🌸

xe_exec_queue_tlb_inval_last_fence_set — literally sets the last fence for TLB invalidation, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

void xe_exec_queue_tlb_inval_last_fence_set (struct xe_exec_queue *q ,
   struct xe_vm *vm , struct dma_fence *fence , unsigned int type );

return type is void, so like… she doesn't return anything, she just does it, main character energy 👑

---

🎀 ARGUMENTS 🎀

• q — the exec queue 💫 like, the queue we're doing this to
• vm — the VM that the engine does a bind for 🌈
• fence — the fence 🫶 yes. that one.
• type — either primary or media GT ⭐ pick one, bestie, those are the options

---

💜 DESCRIPTION 💜

so what she does is: set the last fence for the tlb invalidation type on the queue 🔥 that's it, that's the job.

important part, don't skip this 🙈 — it increases the reference count for fence, which means when you're closing the queue you gotta call xe_exec_queue_tlb_inval_last_fence_put. not optional, not a suggestion, that's the cleanup rule, periodt 💅

fr fr: set it → refcount goes up → put it when the queue closes. that's the contract 🧚
