hi,
after getting r300 working on my Radeon 9600SE under Linux, I am trying to make the same thing happen under Xen (in domain0).
However, I get the following error when loading drm.ko:
Linux agpgart interface v0.100 (c) Dave Jones agpgart: Detected an Intel i875 Chipset. agpgart: Maximum main memory to use for agp memory: 198M agpgart: AGP aperture is 32M @ 0xe0000000 [drm] Initialized drm 1.0.0 20040925 PCI: Obtained IRQ 16 for device 0000:01:00.0 [drm] Initialized radeon 1.12.1 20041216 on minor 0: agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V3 device at 0000:00:00.0 into 4x mode agpgart: Putting AGP V3 device at 0000:01:00.0 into 4x mode [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held, held 0 owner 00000000 c9958f6c [drm:drm_unlock] *ERROR* Process 6699 using kernel context 0 mtrr: reg: 1 has count=0 mtrr: reg: 1 has count=0
Does this look familiar to anyone?
I'm not familiar with Xen, but I heard one of the few drivers which are problematic with it are the agp drivers. This _could_ be such an issue. If so the Xen guys are likely to know more about it. That's really just a guess though.
