            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.
