https://bugs.freedesktop.org/show_bug.cgi?id=34493 Summary: r600g performance regression introduced by 467023e8 (Marek OlÅÃk: r600g: use the same upload buffer for vertices, indices, and constants) Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: dawitbro@xxxxxxxxxxxxx As detailed in Comment 6 of bug 34156, I found this regression in Mesa 7.11-git while trying to pin down another performance regression a few commits earlier. I was able to create a local branch where I was able to reverts 4 commits from a series by Henri Verbeet, which restored performance to the level which existed before that series was introduced. Performance remained high after the 4 reverts until commit 467023e8 was introduced. Reverting this commit (in addition to the 4 mentioned in the other bug report: 077c448d, 7687eaba, 1fa95c7f, and a77e813d) restores performance. All further Mesa commits through the next 10 days (up to the HEAD I have currently, which is fd8d4b32 of Feb. 18) are working fine. I am using r600g on 64-bit Linux, with the following hardware + software: Hardware: Radeon HD 5750 (Evergreen JUNIPER) Software: kernel 2.6.37 (+ radeon cherry-picks from drm-fixes) libdrm 2.4.23 xorg-server 1.9.4 xf86-video-ati 6.14.0 If I can provide any further info/assistance, just let me know. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
