The problem is fixed in 4.12, i can get normal performance in vulkan again... but not all is perfect... After the kernel update to 4.12 and also a firmware update from the distro, i see no errors on the dmesg (probably the most of the errors were firmware related?), but i found that after several suspend cycled, the GPU is locked in the lowest mclck and even the sclck seems to be harder to increase. As per radeon-profile, the performance is still auto and even trying to switch to high or manual makes no difference, mclck is locked on the lower value. So something in the suspend *sometimes* lock GPU the power profile on a lower state. I also found that even after boot, and switching to manual, i can't decrease the mclock, at least it by default on the highest setting, but i may point to some problem switching the mclck. sclck i can manually change, so no problem there. Thanks for all the mesa and amdgpu work higuita --=20 Naturally the common people don't want war... but after all it is the leaders of a country who determine the policy, and it is always a=20 simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are=20 being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in every country. -- Hermann Goering, Nazi and war criminal, 1883-1946 --Sig_/U/LeVI0D.LhS8wmsV2ft9HQ Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iF0EARECAB0WIQQzYESp8QLV9Wpl3Vuu/WNrOwxyswUCWWMCLQAKCRCu/WNrOwxy s8S2AJ9SYBcnO8Zh86L73gOi4XCGsneZvQCgiG/aoFufW1ZZ18cYfXIx0T8YHm4= =0mJT -----END PGP SIGNATURE----- --Sig_/U/LeVI0D.LhS8wmsV2ft9HQ-- --===============0370699535== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: base64 Content-Disposition: inline X19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX18KZHJpLWRldmVs IG1haWxpbmcgbGlzdApkcmktZGV2ZWxAbGlzdHMuZnJlZWRlc2t0b3Aub3JnCmh0dHBzOi8vbGlz dHMuZnJlZWRlc2t0b3Aub3JnL21haWxtYW4vbGlzdGluZm8vZHJpLWRldmVsCg== --===============0370699535==--
