After updating to a git build of the amd-staging-next branch (previous from July), approximately the lower half of my UWQHD screen was garbled. I bisected the issue to this commit: 5ae6fe572929587a304471bf4a641361a45152b5 drm/amd/display: Use calculated disp_clk_khz value for dce110 Let me know if anything else is needed.
Realized I forgot to include some important info for the initial report: Card: Sapphire Nitro RX 580 4 GB Monitor: Monoprice 35 3440x1440@100 Hz via DP 1.2 connection Distro: Arch Linux testing repositories, up to date Mesa: up-to-date git, can look up HEAD if needed
Thanks for the report. This had a Vega specific fix in mind but I guess it extends to Polaris as well. I would imagine the first patch from this thread should fix your issue (ie. the one that's *not* the dce120 one) https://bugzilla.kernel.org/show_bug.cgi?id=201067 If it doesn't, then you should post your full dmesg and Xorg logs.
Thanks for the patch (and sorry for the delayed review). The revert did the trick and works fine here. Just curious, was this superseded by b6bb2aa2181037c9f6083aa2016e1c7e7424e0f3 in Alex's tree?
