From e3a01c14e806f10e2427d067814db7af1cc85952 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 9 Dec 2021 12:13:53 -0600 Subject: [PATCH] drm/amd/pm: fix reading SMU FW version from amdgpu_firmware_info on YC commit dcd10d879a9d1d4e929d374c2f24aba8fac3252b upstream. This value does not get cached into adev->pm.fw_version during startup for smu13 like it does for other SMU like smu12.
