Created attachment 25339 [details] glxinfo When I upgraded from ubuntu 8.04 to 9.04 I had to ditch the catalyst 9.3 driver and use the open source radeon driver. In glxgears with the catalyst driver I was getting +1000fps but with the radeon driver I get 300fps. I have not quantified other drawing operations but the system now is definately much slower than before. Is there something I can try to speed things up? Attached are glxinfo and Xorg.log. I can provide any other information required. $ lspci -vnn | grep -i radeon 01:05.0 VGA compatible controller [0300]: ATI Technologies Inc RS690M [Radeon X1200 Series] [1002:791f]
Created attachment 25340 [details] Xorg.log Adding xorg.log too.
This was a regression in mesa 7.4 which should be fixed in the radeon-rewrite branch of mesa.
Ok cool. When do you think that branch will be released? Should I try the branch in the mean time? It built fine but I am a little hesitant to install it.

You can use the LIBGL_DRIVERS_PATH env var to test before you install: LIBGL_DRIVERS_PATH=/path/to/new/lib glxinfo
I still get about 300fps in glx gears with the radeon-rewrite branch. $ LIBGL_DRIVERS_PATH=`pwd` glxgears libGL: XF86DRIGetClientDriverName: 5.3.0 r300 (screen 0) libGL: OpenDriver: trying /home/jon/svn/mesa/lib/tls/r300_dri.so libGL: OpenDriver: trying /home/jon/svn/mesa/lib/r300_dri.so drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 4, (OK) drmOpenByBusid: Searching for BusID pci:0000:01:05.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 4, (OK) drmOpenByBusid: drmOpenMinor returns 4 drmOpenByBusid: drmGetBusid reports pci:0000:01:05.0 libGL: Can't open configuration file /etc/drirc: No such file or directory. libGL: Can't open configuration file /home/jon/.drirc: No such file or directory. 1491 frames in 5.0 seconds = 298.167 FPS 1481 frames in 5.0 seconds = 296.077 FPS 1495 frames in 5.0 seconds = 298.999 FPS $ LIBGL_DRIVERS_PATH=`pwd` glxinfo | grep OpenGL libGL: XF86DRIGetClientDriverName: 5.3.0 r300 (screen 0) libGL: OpenDriver: trying /home/jon/svn/mesa/lib/tls/r300_dri.so libGL: OpenDriver: trying /home/jon/svn/mesa/lib/r300_dri.so drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 4, (OK) drmOpenByBusid: Searching for BusID pci:0000:01:05.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 4, (OK) drmOpenByBusid: drmOpenMinor returns 4 drmOpenByBusid: drmGetBusid reports pci:0000:01:05.0 libGL: Can't open configuration file /etc/drirc: No such file or directory. libGL: Can't open configuration file /home/jon/.drirc: No such file or directory.

The radeon-rewrite branch improves performance with sauerbraten. With mesa 7.4 I was getting 3fps, but with the radeon-rewrite branch now I get 20fps. I will try installing the libs to my system and update with any new information.
Hi folks I am experiencing the degradation in performance since upgrading to Ubuntu Jaunty though I am only at this point concerned with 2D, not 3D. I would be quite happy to try this radeon-rewrite branch and feed back the results if someone could explain to me how to install it. Many thanks Glen
Mesa 7.4 is no longer supported. RS690 should work fine with the R300 Gallium driver and LLVM enabled.
Performance of RS690M with Mesa 10 and kernel 3.13rc6 isn't good: above ~400 fps in glxgears. This less than at proprietary driver.
