Does updating libdrm to 2.4.47 help? If the new libdrm doesn't help, does Option "ColorTiling2D" "off" or Option "ColorTiling" "off" work around the problem? Upgraded to libdrm 2.4.47 and the issue is still reproduced. The issue is not observed with Option "ColorTiling2D" "off", however it reduces the driver performance i.e. for game Openarena the FPS is reduced by approx 30% with Color Tiling disabled. What was the last working version of Mesa? Are you able to bisect? Here are the regression details Pass : xf86-video-ati-0c921edf(31st Oct) Fail : xf86-video-ati-e4cd0f43(4th Nov) with Mesa-10.0.0-devel(git-6c6f4aa) I have the same issue with Cape Verde PRO [Radeon HD 7750] software versions: media-libs/mesa-10.0.2 sys-devel/llvm-3.4 sys-kernel/hardened-sources-3.12.6-r4 x11-drivers/xf86-video-ati-9999 (latest git)) x11-libs/glamor-9999 (latest git) x11-libs/libdrm-2.4.50 (In reply to comment #7) > Here are the regression details > > Pass : xf86-video-ati-0c921edf(31st Oct) > Fail : xf86-video-ati-e4cd0f43(4th Nov) e4cd0f43 is a commit which enables tiling on SI by default and it's not a real regression. I didn't tried ColorTiling2D until today, so I'm not sure if it worked in the past (btw, same corruption with xf86-video-ati-7.2.0 and ColorTiling2D enabled). I have same problem with card AMD Radeon HD 7730. When glamor is enabled I see same screen corruption (as in attached screenshot) in Xserver (also in login screen KDM). When glamor is disabled everything is OK, but very very slow. Problem is still present in mesa, drm, xorg ati - all from git from end of December. Problem is also in Fedora live CD which has enabled radeonsi and glamor by default. Enabling/Disabling ColorTiling and ColorTiling2D did not help I still saw same problem. (In reply to comment #10) > Enabling/Disabling ColorTiling and ColorTiling2D did not help I still saw same > problem. This contradicts comment #5, so it's probably not the same issue. Please file your own report with all the necessary information. So it looks like it is problem as reported in bug #60879 *** Bug 74927 has been marked as a duplicate of this bug. *** Created attachment 94233 [details] [review] possible fix This patch should fix the issues. *** Bug 73946 has been marked as a duplicate of this bug. *** (In reply to comment #14) fixed on OLAND. thanks. Fixed on VERDE too. Thanks! |
