After restore, GuC will not answer to any messages from VF KMD until fixups are applied. When that is done, VF KMD sends RESFIX_DONE message to GuC, at which point GuC resumes normal operation. This patch implements sending the RESFIX_DONE message at end of post-migration recovery. v2: keep pm ref during whole recovery, style fixes (Michal) v3: assert removal to separate patch, debug message per GuC instead of one, comments changes (Michal) v4: improve one debug message (Michal) Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241104213449.1455694-4-tomasz.lis@intel.com Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com>
