🦋 amdgpu_gtt_..._bo_teardown(9) 🦋

okay bestie, this page is from the Kernel API Manual, and it is highkey deep in AMD GPU internals. The main character is amdgpu_gtt_mgr_mark_bo_teardown, and its whole job is to exclude a BO from GART recovery. Periodt. 💅

💖 NAME 💖

• amdgpu_gtt_mgr_mark_bo_teardown — exclude a BO from GART recovery ✨

🌸 SYNOPSIS 🌸

void amdgpu_gtt_mgr_mark_bo_teardown (struct ttm_buffer_object *tbo );

🎀 ARGUMENTS 🎀

• tbo — the TTM BO whose TT backing is about to be destroyed 😭 like, it's on the way out, bestie.

🫶 DESCRIPTION 🫶

So here's the tea: keep the GART range allocated until the resource is freed, but make recovery treat it like a range without a BO so it isn't touched after TT teardown has started. no cap, that's the whole vibe. 💜
