Bug ID: 112234 Summary: [REGRESSION] navi10: writing to pp_table fails (5.4-rc6 = working) Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: not set Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: mcoffin13@gmail.com
Created attachment 145913 --> https://bugs.freedesktop.org/attachment.cgi?id=145913&action=edit dmesg log (journalctl -k) for the failure.
On 5.4-rc6, with navi10, writing to the sysfs pp_table works, with the SMU resetting successfully.
On amd-staging-drm-next (270209307880ec946cfe9b98a6a58d285dbc5a2e), this fails. I can bisect, but unfortunately I'm not too sure on where to start, since the amd-staging-drm-next branch is currently rebased off of an older version (5.3-rcX I think?). Tips on where to start would be helpful and appreciated, but my guess that this would be introduced in the big refactor to remove the swSMU code layer.
