https://bugzilla.kernel.org/show_bug.cgi?id=46161 --- Comment #3 from bjackson0971@xxxxxxxxx 2012-09-03 21:58:07 --- I had to bisect between 3.4.0 and 3.5-rc1 and this was the result. 416a2bd274566a6f607a271f524b2dc0b84d9106 is the first bad commit commit 416a2bd274566a6f607a271f524b2dc0b84d9106 Author: Alex Deucher <alexander.deucher@xxxxxxx> Date: Thu May 31 19:00:25 2012 -0400 drm/radeon: fixup tiling group size and backendmap on r6xx-r9xx (v4) Tiling group size is always 256bits on r6xx/r7xx/r8xx/9xx. Also fix and simplify render backend map. This now properly sets up the backend map on r6xx-9xx which should improve 3D performance. Vadim benchmarked also: Some benchmarks on juniper (5750), fullscreen 1920x1080, first result - kernel 3.4.0+ (fb21affa), second - with these patches: Lightsmark: 91 fps => 123 fps +35% Doom3: 74 fps => 101 fps +36% Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Jerome Glisse <jglisse@xxxxxxxxxx> Signed-off-by: Dave Airlie <airlied@xxxxxxxxxx> :040000 040000 897f0745cc0845c549d44d172c2949cc92b4777c 4c08505d2b214813be5c65e4b87bb809ff027ce2 M drivers -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
