xe_vm_unlock(9)

💅 xe_vm_unlock — like, the Kernel API Manual page for it ✨

okay so bestie, welcome to xe_vm_unlock from the Kernel API Manual — this is the little guy whose whole entire job is unlocking the vm's dma_resv object. That's it. That's the gig. And honestly? Iconic. 🎀

---

✨ SYNOPSIS ✨

void xe_vm_unlock (struct xe_vm *vm );

no cap, that's the whole signature. void return, so it's giving "I do the thing and I don't even need to report back." main character energy fr fr. 👑

---

🌸 ARGUMENTS 🌸

• vm — the struct xe_vm whose lock is to be released. yes, that vm. the one you locked. hand it over so it can be freed from lock jail. 🫶

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function unlocks a buffer object lock that was locked by xe_vm_lock. that's literally it. it's the "undo" button for xe_vm_lock, the yin to its yang, the paired set of skinny jeans if you will. 💖

ngl the description is short but like — sometimes the simplest ones are the most powerful. lock goes in, lock comes out. slay. ✨

🫶 reminder bestie: only unlock what you locked with xe_vm_lock. don't be out here releasing locks that were never yours, that's not the vibe.
