✨ amdgpu_ttm_evict_resources(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a little function from the amdgpu fam and honestly it's giving "cleanup crew, but make it glam" 🧚 we're literally just yeeting memory buffers out of a list, no cap.

---

🌸 NAME 🌸

amdgpu_ttm_evict_resources — evict memory buffers 🫶

---

⭐ SYNOPSIS ⭐

int amdgpu_ttm_evict_resources (struct amdgpu_device *adev , int
mem_type );

that's it, that's the whole vibe check 🔥

---

🎀 ARGUMENTS 🎀

• adev — the amdgpu device object 💖 like, the actual GPU friend we're working on.
• mem_type — the memory type of the BO's that are getting evicted ✨ (yes, BO = buffer object, iykyk).

---

💅 DESCRIPTION 💅

so what does it do bestie? it evicts all the mem_type buffers sitting on the lru list of that memory type 🌈 periodt. every single one on that list, gone, evicted, bye 💀

👑 RETURN 👑

0 for success 🎉 or a negative error code if it fails 😭 (yes, negative — check it, don't ignore it, fr fr).

okay that's the page!! mwah 💋 it comes from the ./drivers/gpu/drm/amd/amdgpu directory and the date on it is October 2026 🌸 so like, future vibes only. stay slay, go evict those buffers, and remember: amdgpu_ttm_evict_resources(9) ate and left no crumbs 👑✨
