Revert "drm/amd: fix gfx hang on renoir in IGT reload test"

2025-11-24T17:35:15+00:00

The original patch introduced additional latency during boot time because it triggers a driver reload to avoid a CP hang when the driver is reloaded multiple times. This has been addressed with a more generic solution that triggers the GPU reset only during the unload phase, avoiding extra latency during boot time. For this reason, this commit reverts the original change. This reverts commit 72a98763b473890e6605604bfcaf71fc212b4720. This patch should only be applied if commit: 4355e61835e7 ("drm/amdgpu: Fix GFX hang on SteamDeck when amdgpu is reloaded") is present.

drm/amdgpu: refactor bad_page_work for corner case handling

2025-08-15T17:07:30+00:00

When a poison is consumed on the guest before the guest receives the host's poison creation msg, a corner case may occur to have poison_handler complete processing earlier than it should to cause the guest to hang waiting for the req_bad_pages reply during a VF FLR, resulting in the VM becoming inaccessible in stress tests. To fix this issue, this patch refactored the mailbox sequence by seperating the bad_page_work into two parts req_bad_pages_work and handle_bad_pages_work. Old sequence: 1.Stop data exchange work 2.Guest sends MB_REQ_RAS_BAD_PAGES to host and keep polling for IDH_RAS_BAD_PAGES_READY 3.If the IDH_RAS_BAD_PAGES_READY arrives within timeout limit, re-init the data exchange region for updated bad page info else timeout with error message New sequence: req_bad_pages_work: 1.Stop data exhange work 2.Guest sends MB_REQ_RAS_BAD_PAGES to host Once Guest receives IDH_RAS_BAD_PAGES_READY event handle_bad_pages_work: 3.re-init the data exchange region for updated bad page info Signed-off-by: Chenglei Xie Reviewed-by: Shravan Kumar Gande Signed-off-by: Alex Deucher
