[Bug 105300] amd-staging-drm-next-git 4.16 & RX 560 DL-DVI: corruption with refreshrates >73Hz when DPM changing VRAM clock

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #15 from tempel.jul...@gmail.com --- Issue still exists with current 4.21-wip kernel. As a workaround, it's enough to force the highest VRAM clock state (Forcing higher clocks on the GPU itself is not necessary.): echo "manual" >

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #14 from tempel.jul...@gmail.com --- 73Hz + dynamic clocking work again with recent drm-next-4.19-wip build. As a sidenote: On Windows (which is installed on the same system as a 2nd OS), there has never been an issue with 75Hz

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #13 from tempel.jul...@gmail.com --- Since a month back or so, also 73Hz now shows the artifacts. 72Hz is still artifact free. -- You are receiving this mail because: You are the assignee for the

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #11 from tempel.jul...@gmail.com --- One of the recent changes in drm-next-4.17-wip has also introduced this issue for the old legacy DC. -- You are receiving this mail because: You are the assignee for the

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #10 from tempel.jul...@gmail.com --- I thought of something similar too. But I'm far away from 330Mhz pixel clock. I'm just using LCD standard timings, which result in a pixel clock of 304.37MHz: https://abload.de/img/75hzhgs1d.png

https://bugs.freedesktop.org/show_bug.cgi?id=105300 --- Comment #3 from Harry Wentland --- Good point. Do you mind posting a picture of what you're seeing? It often helps clarify what sort of corruption is happening and helps us understand which part of the pipeline is
