I see a problem with this tree (and possibly with ones from previous days - I haven't tested next in 2-3 days or so). I have no direct rendering as reported by glxinfo, whereas with Linus' latest tree I do.
I checked my logs and I see:
PCI: Using ACPI for IRQ routing PCI: Cannot allocate resource region 0 of device 0000:00:00.0 agpgart: Detected AGP bridge 0 agpgart: Aperture conflicts with PCI mapping. agpgart: Aperture from AGP @ e0000000 size 128 MB agpgart: Aperture conflicts with PCI mapping. agpgart: No usable aperture found. agpgart: Consider rebooting with iommu=memaper=2 to get a good aperture.
In a working kernel, all I see is:
PCI: Using ACPI for IRQ routing agpgart: Detected AGP bridge 0 agpgart: Aperture from AGP @ e0000000 size 128 MB
Does anyone have any idea where I would start to look for the cause? Would it be a PCI problem? An AGP problem? An x86 problem?
If necessary I can bisect, but 12-13 compile-boot cycles will take me a few evenings worth of computer time. A targeted revert or two to try would help.
