amdgpu_bo_move_notify(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

Bestie, say hi to amdgpu_bo_move_notify(9) from the Kernel API Manual 🫶 — it's a notification about a memory move, and that's literally the whole name. Periodt. 💅

🌸 SYNOPSIS 🌸

       void amdgpu_bo_move_notify (struct ttm_buffer_object *bo , bool evict ,
       struct ttm_resource *new_mem );

💅 ARGUMENTS 💅

  • bo — pointer to a buffer object. Yes bestie, the BO in question. 🎀
  • evict — if this move is evicting the buffer from the graphics address space. That's the vibe check right there. ✨
  • new_mem — new resource for backing the BO. Fresh backing resource, slay. 🦋

🎀 DESCRIPTION 🎀

This is the TTM driver callback that gets called when ttm moves a buffer. When it runs, it marks the corresponding amdgpu_bo buffer object as invalid, and it also performs bookkeeping. So yeah: memory move happens, notification happens, bookkeeping gets done. Iconic little kernel callback behavior. 💖
