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 <Chenglei.Xie@amd.com> Reviewed-by: Shravan Kumar Gande <Shravankumar.Gande@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 2025-07-28T20:40:07+00:00 Lijo Lazar lijo.lazar@amd.com 2025-07-25T04:51:10+00:00 urn:sha1:21c6764ed4bfaecad034bc4fd15dd64c5a436325 Use different external revid for GC v9.5.0 SOCs.
