Hi, I have a 3D visualization tool that crashes with the 3.X versions of the Mesa that are in <=XF86 4.2.0. I noticed in the changelog that Mesa 4.0.2 has been add to the latest CVS so I thought I would give it a try. Without DRI everything works great (except for the speed of course). The problems arise when I want to use DRI. I'll try to give all the backgroud information first, if I miss an important detail please let me know.
My system is a clean RedHat 7.3 install on a dual athlon machine. My graphics card is Matrox G550. DRI loads and 'glxgears' works great with the XF86 4.2.0 that comes with RedHat 7.3. I download the CVS on July 16 and did a 'make World' and then a 'make install'. Everything seems to install ok and X starts without any problems. I recompiled the DRI module for mga and installed it in the appropriate /lib/modules directory and did a 'depmod -a' Using the same XF86Config-4 file from the 4.2.0 version under 4.2.99, DRI fails to load....... (II) MGA(0): [drm] bpp: 32 depth: 24 (II) MGA(0): [drm] Sarea 2200+664: 2864 drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (No such device) drmOpenDevice: Open failed drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (No such device) drmOpenDevice: Open failed [drm] failed to load kernel module "mga" (II) MGA(0): [drm] drmOpen failed (EE) MGA(0): [drm] DRIScreenInit failed. Disabling DRI. I think the reason that DRI fails to load is found in 'dmesg'. The following appears during startup of the X server: [drm:drm_init] *ERROR* Cannot initialize the agpgart module. I find this very strange since the agpgart hasn't changed since it loaded perfectly well under 4.2.0. I tried loading the mga module manually. With 'modprobe mga' I get: /lib/modules/2.4.18-3smp/kernel/drivers/char/drm/mga.o: init_module: Cannot allocate memory Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters /lib/modules/2.4.18-3smp/kernel/drivers/char/drm/mga.o: insmod /lib/modules/2.4.18-3smp/kernel/drivers/char/drm/mga.o failed /lib/modules/2.4.18-3smp/kernel/drivers/char/drm/mga.o: insmod mga failed If I load the agpgart module first, then I can load the mga module without errors. However, If I manually load agpgart and mga, start X and then try to run 'glxgears' by system freezes and I have to reboot. Another interesting point is that if I start XF86 4.2.0 and exit, the modules remain installed. I can then start XF86 4.2.99 with the modules installed by 4.2.0 and have DRI and glxgears work great. So I have come to the conclusion (of course I could be wrong) that the 4.2.99 version of XF86 loads the DRI or agpgart modules incorrectly. If I have overlooked something that I should try please let me know. If this isn't suppose to be supported yet and I just have to deal with Indirect rendering pelase let me know. Please just let me know anything, I have played around with this for a long time and it is becoming an obsession which needs to die so I can acutally do work. Thanks for you time, Diek Van Nort A few more outputs that might be of interest............. The thing that I find interesting is the "OpenGL version string:" When I try to load the modules manually I get 1.2 Mesa 4.0.2, when the modules fail to laod I get "1.3 Mesa 4.0.2" Could it be that DRI is trying to load the wrong version of OpenGL Mesa API? The output of 'glxinfo' when I load the drivers manual is as follows: name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 server glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context client glx vendor string: SGI client glx version string: 1.2 client glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context GLX extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context OpenGL vendor string: VA Linux Systems Inc.
