I have a new ibook with an ATI Mobility Radeon 9550 card and want to help the r300 project testing the driver. I have compiled the patched x server and the mesa drivers from cvs. I also have compiled radeon.ko from the drm cvs of the dri project.
With the help of Vladimir Dergachev (aka volodya), the r300 driver, I made the radeon.ko driver see mi card by adding my it to drm_pciids.txt. I attach the patch. It seems that there is a problem with agp when x starts. Vladimir thinks that it is related to powerpc and told me to post here. This are the important parts of the logs: /var/log/Xorg.0.log =========== WW) RADEON(0): Direct rendering support is highly experimental for Radeon 9500/9700 and newer cards 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:0000:00:10.0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 8, (OK) drmOpenByBusid: drmOpenMinor returns 8 drmOpenByBusid: drmGetBusid reports pci:0000:00:10.0 (II) RADEON(0): [drm] DRM interface version 1.2 (II) RADEON(0): [drm] created "radeon" driver at busid "pci:0000:00:10.0" (II) RADEON(0): [drm] added 8192 byte SAREA at 0xe2111000 (II) RADEON(0): [drm] mapped SAREA 0xe2111000 to 0x320cc000 (II) RADEON(0): [drm] framebuffer handle = 0x98000000 (II) RADEON(0): [drm] added 1 reserved context for kernel (II) RADEON(0): [agp] Mode 0x07000201 [AGP 0x106b/0x0034; Card 0x1002/0x4e56] (II) RADEON(0): [agp] 8192 kB allocated with handle 0x00000001 (EE) RADEON(0): [agp] Could not add ring mapping (EE) RADEON(0): [agp] AGP failed to initialize.

If you think that debugging log will be useful, don't hesitate in saying so. This is all the information I can gather, I hope that it will be enough. PS: drm drivers are compiled from drm project cvs and the kernel is 2.6.12
