Hi all,
Since upgrading from xorg 6.8.x to 6.9 I don't have any hw acceleration anymore (actually, if I had any). Moving anything around the screen or scrolling is horribly slow right now, and I can't get back to 6.8 (I deleted the corresponding .deb files I had) Display hw is ATI Radeon 9550 (r350) . Up to now (6.8.x) this was nothing like the fastest, but quite acceptable for development. Now (with xorg 6.9) it's way to slow. Reading X log files /var/log/Xorg.0.log, I get messages of DRI successfully started, and no clear error messages related to DRI. Although I do get this warning : (WW) RADEON(0): Enabling DRM support *** Direct rendering support is highly experimental for Radeon 9500 *** and newer cards. The 3d mesa driver is not provided in this tree. *** A very experimental (and incomplete) version is available from Mesa CVS. *** Additional information can be found on http://r300.sourceforge.net *** This message has been last modified on 2005-08-07. But this should also have been the case with xorg 6.8.x, no ? Beside it is followed by these messages : drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 8, (OK) drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 8, (OK) drmOpenByBusid: Searching for BusID pci:0000:01:00.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 8, (OK) drmOpenByBusid: drmOpenMinor returns 8 drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0 (II) RADEON(0): [drm] DRM interface version 1.2 (II) RADEON(0): [drm] created "radeon" driver at busid "pci:0000:01:00.0" (II) RADEON(0): [drm] added 8192 byte SAREA at 0x10001000 (II) RADEON(0): [drm] mapped SAREA 0x10001000 to 0x2aaab52b7000 (II) RADEON(0): [drm] framebuffer handle = 0xe8000000 (II) RADEON(0): [drm] added 1 reserved context for kernel Unfortunately lower down I get : (II) RADEON(0): Render acceleration unsupported on Radeon 9500/9700 and newer. (II) RADEON(0): Render acceleration disabled But, again, this should also have been the case with xorg 6.8.x. as well. and this is followed by : (II) RADEON(0): Using XFree86 Acceleration Architecture (XAA) Screen to screen bit blits Solid filled rectangles 8x8 mono pattern filled rectangles Indirect CPU to Screen color expansion Solid Lines Scanline Image Writes Offscreen Pixmaps Setting up tile and stipple cache: 32 128x128 slots 32 256x256 slots 16 512x512 slots (II) RADEON(0): Acceleration enabled and : (II) RADEON(0): [drm] installed DRM signal handler (II) RADEON(0): [DRI] installation complete (II) RADEON(0): [drm] Added 32 65536 byte vertex/indirect buffers (II) RADEON(0): [drm] Mapped 32 vertex/indirect buffers (II) RADEON(0): [drm] dma control initialised, using IRQ 177 (II) RADEON(0): [drm] Initialised kernel GART heap manager, 5111808 (II) RADEON(0): Direct rendering enabled So as far as I could see, whatever DRM I must have had with xorg 6.8.x is still there. Yet xorg 6.9 is still horribly slow ! Now trying out glxgear I could indeed see only a few frames per second (about 260) !! I don't have any numbers anymore for 6.8.x, but the frames per sec were never this bad. Actually I seem to remember I could not follow the gears with my eyes last time I looked. checking out glxinfo with LIBGL_DEBUG=verbose :~$ glxinfo name of display: :0.0 libGL: XF86DRIGetClientDriverName: 4.0.3 r300 (screen 0) libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/r300_dri.so libGL error: dlopen /usr/X11R6/lib/modules/dri/r300_dri.so failed (/usr/X11R6/lib/modules/dri/r300_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to find driver: r300_dri.so display: :0 screen: 0 direct rendering: No ... snip, snip ... I thought : Aha ! r300_dri.so ? Debian does not seem to provide it in any package, although there is a radeon_dri.so and a r200_dri.so (which don't seem to work for me). There are many fleeting references to r300_dri.so in many places (google and others) however no clear pointer to where it can be found. Anybody knows more about this file ? Do I need it for KDE ? Does anybody knows any other reason why after upgrading to 6.9 xorg it lost the little hw acceleration it had ? This is very annoying as I don't want to go to ati's proprietary drivers.
