i915_vma_resource_unbind(9)

💅 i915_vma_resource_unbind(9) 💅

okay so welcome to the Kernel API Manual bestie, this is the page for i915_vma_resource_unbind and honestly? it's a whole mood. let's get into it 🎀

---

✨ NAME ✨

i915_vma_resource_unbind — unbind a vma resource, that's literally the whole gig 🫶

---

🌸 SYNOPSIS 🌸

struct dma_fence * i915_vma_resource_unbind (struct i915_vma_resource
*vma_res , u32 *tlb );

---

🦋 ARGUMENTS 🦋

• vma_res — the vma resource you're unbinding. the main character of this function, if you will 👑
• tlb — a pointer to vma->obj->mm.tlb that's associated with the resource, and it gets stored at vma_res->tlb. when it's not-NULL, it's gonna be used to do TLB cache invalidation before freeing a VMA resource. it's only used for async unbind, so like… don't come for it if it's sitting there doing nothing in the sync case 🙈

---

💖 DESCRIPTION 💖

ngl, at this point in time this function does little more than publish a fence that signals immediately — unless signaling is being held back. that's it. that's the whole function. it's giving "small but mighty" energy ✨

---

🔥 RETURN 🔥

a refcounted pointer to a dma-fence that signals when unbinding is complete. so like, when that fence goes off, you're done, slay 💅

bestie note: the tlb arg is only for async unbind, ok? don't be out here assuming it does something in every path 💀
