Summary: HD4290 (Asus M4A89GTD/Pro onboard): no DRI (/dev/dri/card0) with CONFIG_DRM_RADEON_KMS enabled Product: DRI Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: freedesktop@erben.com
I have a Debian (somewhere between unstable and testing) and a homebrewn kernel (v3.0.1 with vserver 2.3.1-pre9) on my M4A89GTD/Pro. The M4A89GTD/Pro has HD4290 on-board graphics (RS880). There's no other graphic card installed. For bootup I have a vesa console framebuffer configured but no radeon (couldn't get it to work). If I set in my kernel .config file
CONFIG_DRM_RADEON=y CONFIG_DRM_RADEON_KMS=y
a dmesg shows:
[drm] Initialized drm 1.1.0 20060810 [drm] radeon defaulting to kernel modesetting.

Unnecessary to tell, that there are no /dev/dri/* around then. If I unset CONFIG_DRM_RADEON_KMS I get:
[drm] Initialized drm 1.1.0 20060810 [drm] radeon defaulting to userspace modesetting. pci 0000:01:05.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 pci 0000:01:05.0: setting latency timer to 64 [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

and /dev/dri/card0 is present. The Problem however is that the libGL (Debian libgl1-mesa-glx v7.11-5, xorg v1:7.5+8) has Problems with that:

The performance of X (measured with glxgears) without KMS (~630 FPS) is better than with KMS and no DRI (~85 FPS), but there should be more.
Do you have any idea, what I can change? Or, can I do more to help analyzing this?
