Hi,

I just noticed that I don't have accelerated GL any more with the
modesetting i810 driver.

$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: No

I'm using i810 from modesetting git, libdrm 2.3.0, and drm.ko/i915.ko
from drm git.

Kernel logs:

Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected an Intel 945GM Chipset.
agpgart: Detected 7932K stolen memory.
agpgart: AGP aperture is 256M @ 0xd0000000
[drm] Initialized drm 1.1.0 20060810
[drm] Initialized i915-mm 1.7.0 20060929 on minor 0

X logs:

(II) I810(0): [drm] installed DRM signal handler
(II) I810(0): [DRI] installation complete
(II) I810(0): [drm] dma control initialized, using IRQ 201
(II) I810(0): direct rendering: Enabled
(II) I810(0): RandR enabled, ignore the following RandR disabled message.
(II) I810(0): Rotating to 0 degrees
(EE) I810(0): Too little AGP aperture space for DRM memory manager.
        Please increase AGP aperture size from BIOS configuration screen
        or decrease the amount of video RAM using option "VideoRam".
        Disabling DRI.

The full xorg.log is attached.  Direect rendering worked with the stock
Edgy (Xorg 7.1) driver, so what has changed?
