💖 xe_bo_evict_all_user(9) 💖

okay so this is a page straight out of the Kernel API Manual, section 9, and the whole main-character of it is xe_bo_evict_all_user — yes that's a mouthful, we love her anyway 🫶. She's a kernel function, she lives in the xe driver, and she's about to politely yeet your BOs out of VRAM. Buckle up bestie ✨

🌸 NAME 🌸

xe_bo_evict_all_user — evict all non-pinned user BOs from VRAM

like, all of them. the non-pinned ones. the user ones. out of VRAM. that's the whole job description 💅

---

🎀 SYNOPSIS 🎀

int xe_bo_evict_all_user (struct xe_device *xe );

she takes one (1) argument and hands you back an int. iconic signature tbh ⭐

---

🦋 ARGUMENTS 🦋

• xe — the xe device. that's it. that's the whole argument list. she's a simple girl with simple needs 🍓

---

✨ DESCRIPTION ✨

so the vibe is this: xe_bo_evict_all_user evicts non-pinned user BOs — and it does it via GPU 🔥.

and because we don't gatekeep definitions here: evict == move VRAM BOs to temporary memory, which is typically system memory. so bestie is getting relocated out of the fancy VRAM neighborhood and crashing on the system memory couch for a while 😭🛋️

if it's pinned, she stays. pinned BOs are not getting evicted, periodt.
