💖 amdgpu_vram_mgr_intersects(9) 💖

okay bestie so we're in the Kernel API Manual today, and the main character of this page is amdgpu_vram_mgr_intersects — yes that's a whole mouthful, iykyk, just sound it out 🫶

---

✨ NAME ✨

amdgpu_vram_mgr_intersects — test each drm buddy block for intersection 💅

---

✨ SYNOPSIS ✨

bool amdgpu_vram_mgr_intersects (struct ttm_resource_manager *man ,
struct ttm_resource *res , const struct ttm_place *place , size_t size
);

---

✨ ARGUMENTS ✨

• man — the TTM memory type manager, aka the boss of this whole memory-type situation 👑
• res — the resource you're testing, the one under the microscope 🔍
• place — the place you're testing against, like the vibe check opponent 🌸
• size — size of the new allocation, the number that matters fr fr

---

✨ DESCRIPTION ✨

So the whole point?? Test each drm buddy block for intersection — that's it, that's the job — and all of this is so the eviction decision can actually get made 😭

ngl it's a small function with a big responsibility. Every drm buddy block gets checked, no skipping, no shortcuts 💀
