Because nobody reacted on the bug report, I'm trying this way.
As mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=196337, my
system gets unusable with GFX_PG enabled, cause X doesn't start anymore.
Hi Johannes,
Sorry nobody replied. On my A12-9800 devel machine it works fine (and
compute rings work fine finally with KIQ sorted) but there are patches
out from the KFD team wanting to disable it again as well.
You can isolate this by loading amdgpu with pg_mask=0xFFFFFFFE that
should disable GFX_PG. If that solves your issue on an upstream kernel
(or tip of amd-staging-4.12) then likely GFX PG is the issue (or tied to
the issue).
Cheers,
Tom
