Hi Rex,
I bisected a regression to your "drm/amd/pp: Unify
powergate_uvd/vce/mmhub to set_powergating_by_smu" change. Since this
change, the VCE ring test fails on this Kaveri laptop, which prevents
the amdgpu driver from initializing at all, see the the attached kern.log.
If I disable VCE via the ip_block_mask module parameter, I get an oops
in kv_dpm_get_sclk called from amdkfd, see the attached no-vce.log.
Since the change above landed for 4.19-rc1, the regression should be
fixed before the final 4.19 release if at all possible.
Note that before this change, the VCE IB test has always (as far as I
remember) failed on this machine, see the attached vce-ib-fail.log. But
I don't care about that too much, as I don't need VCE, and I haven't
noticed any other issues related to that.
P.S. Somebody else bisected a Mullins issue to the same commit:
