From 2e97663760e5fb7ee14f399c68e57b894f01e505 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Mon, 6 Oct 2025 10:39:03 +0530 Subject: [PATCH 5299/5403] drm/amdgpu: Report individual reset error If reinitialization of one of the GPUs fails after reset, it logs failure on all subsequent GPUs eventhough they have resumed successfully. A sample log where only device at 0000:95:00.0 had a failure - amdgpu 0000:15:00.0: amdgpu: GPU reset(19) succeeded! amdgpu 0000:65:00.0: amdgpu: GPU reset(19) succeeded! amdgpu 0000:75:00.0: amdgpu: GPU reset(19) succeeded! amdgpu 0000:85:00.0: amdgpu: GPU reset(19) succeeded! amdgpu 0000:95:00.0: amdgpu: GPU reset(19) failed amdgpu 0000:e5:00.0: amdgpu: GPU reset(19) failed amdgpu 0000:f5:00.0: amdgpu: GPU reset(19) failed amdgpu 0000:05:00.0: amdgpu: GPU reset(19) failed amdgpu 0000:15:00.0: amdgpu: GPU reset end with ret = -5 To avoid confusion, report the error for each device separately and return the first error as the overall result.
