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. _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx ^ permalink raw reply [flat|nested] 2+ messages in thread

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 _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx ^ permalink raw reply [flat|nested] 2+ messages in thread
