Comment # 39
on bug 110781
from Richard Thier
First I went on to strace a bit and measure directly... 10 sec glxgears - lastfast 17.x: - 2105 ioctl calls - 6 DRM_IOCTL_RADEON_GEM_CREATE - 7 DRM_IOCTL_GEM_CLOSE 10 sec glxgears - patched 19.x: - 2916 ioctl calls - 712 DRM_IOCTL_RADEON_GEM_CREATE - 713 DRM_IOCTL_GEM_CLOSE In comparison this is the unpatched 19.x originally (10 sec): -> 12466 (any) ioctl calls -> 3111 DRM_IOCTL_RADEON_GEM_CREATE -> 3112 DRM_IOCTL_GEM_CLOSE Surely it is already an order of magnitude better now, but maybe still not as best as it should be. As I told you, when bisecting there was a point I saw this happening and it was hinting there are two issues - but one is much smaller. glxgears however runs roughly the same FPS now. Maybe things start to slow down if I run out of CPU power as glxgears don't run out now - neither tuxracer, but will try heavy things like mount&blade: warband... it was working well before..
