okay so this is a page straight out of the Kernel API Manual, and bestie, it's a short one but it's important β it's giving "tiny function, big consequences" energy. Let's get into it β¨
πΈ NAME πΈ
i915_vma_resource_bind_dep_sync β wait for / sync all unbinds touching a certain vm range. that's it, that's the whole vibe π
β¨ SYNOPSIS β¨
int i915_vma_resource_bind_dep_sync (struct i915_address_space *vm , u64
offset , u64 size , bool intr );
like, look at her. four args. no cap, she's booked and busy π
π¦ ARGUMENTS π¦
vmβ the vm we're looking at. main character of this whole operation tbh πoffsetβ where the range starts. the beginning of the story π«Άsizeβ how big the range is. how much of the story we're reading πintrβ whether to waitinterrubtible(yes, that's how the page spells it, and honestly? iconic π). it's abool, so it's a yes-or-no girlie π
π DESCRIPTION π
so here's the thing, bestie, and i need you to hear me on this one: the function needs to be called with the vm lock held. π
not optional. not "eh, probably fine." held. vm lock. held. periodt. π
it waits for and syncs up all the unbinds that touch that certain vm range β so everything in the offset + size window gets its moment to finish before you move on. it's literally doing the group-chat "hold on, everyone finish your thought" move π«Ά
β οΈ for real though β call it with the vm lock held. don't be the girlie who skips that step π
β RETURN β
Zeroon success β slay, we love a clean exit π-ERESTARTSYSif it got interrupted andintr==trueβ aka the wait got cut off mid-sentence π
