unimplemented feature. Let's track here.

Many, many folks with the G41 chipset are affected by this missing DRI support. The desktop graphic performance is unacceptable without it. Any idea what is involved to provide it?

Why does glxinfo report direct rendering anyhow under g41?

The i915 kernel driver doesn't appear to have the G41 PCI IDs yet; Zhenyu Wang posted a patch back in September:

http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg36219.html

This still isn't in Linus' tree but when applied to 2.6.29.1 does seem to result in working DRI/KMS support.

Haien, please attach intel_gtt (a tool under xf86-video-intel) output.

the output of intel_gtt

Thanks, could you paste intel_gtt output when kernel boot with "agp=off" param?

Eric, it looks our G41 doesn't have stolen memory issue that you've seen. Do you have any bios setting for stolen size?

intel_gtt output with "agp=off" is attached.

Haien, please try below drm patch to see if DRI works:

I don't understand why agpgart becomes broken after applying the drm patch.

you left agp=off in kernel boot...

sorry,I forgot it.
dri works with the patch.

Can I know why this patch is not yet pushed into drm-intel git tree. The drm support for G41 is still missing in the kernel.

*** Bug 21425 has been marked as a duplicate of this bug. ***

I'm running 3 DG41TY Fedora 10 computers with the G41 graphics chipset.  I've patched the kernel with https://bugzilla.redhat.com/attachment.cgi?id=337490 and 3D/compiz works fine.

However all of the systems hard lock whenever X is restarted after a random delay (i.e. X starts fine the first time (most of the time), but on the first or second logout, the system hangs with no response to pings, etc.).

I suspect this is why the patch hasn't made it into the mainline kernel.  Is there anything I (or anybody else) can do to help track down the problems so this can get enabled?

FYI: Looks like that patch made it, in a more or less identical state, into the 2.6.30-rc4 mainline:
http://lkml.org/lkml/2009/4/30/10

Thanks for the effort. BTW this was the patch comment from Zhenyu Wang.

"This had been delayed for some time due to failure to work on the one piece
of G41 hardware we had, and lack of success reports from anybody else.
Current hardware appears to be OK."

I've been having ongoing issues with my g41 chipset, so I'm just cc'ing myself in to make it easy to locate this bug.

I'll test tomorrow and see what gives as this appears to have been included in f11

I've tested this using a fedora rawhide livecd which I believe has all the correct bits in it, and this doesn't work for me.

I can't boot the kernel.

I'm not convinced that this bug is fixed.

We believe this common bug has been fixed, as multiple people have confirmed this.

There are also knowns issues for some specific G41 boards: bug#22518 bug#21574. If your issue is differnt, please file a separate bug according to http://intellinuxgraphics.org/how_to_report_bug.html.
