Description Ralf Kaestner 2007-12-03 09:36:09 UTC
xServer does not start in dom0 because the intel 965GM PCI ID is not supported by agpgart in the recent xen dom0 kernel.


including this patch helps:
http://lkml.org/lkml/2007/4/8/102

It solved the issues on my side. xserver starts fine now.



Reproducible: Always

Actual Results:  
on x startup agpgart reports that it is unable to allocate memory.

/var/log/messages looks like that:

Dec  3 01:46:07 gbox Real Time Clock Driver v1.12ac
Dec  3 01:46:07 gbox Linux agpgart interface v0.101 (c) Dave Jones
Dec  3 01:46:07 gbox [drm] Initialized drm 1.1.0 20060810

Expected Results:  
/var/log/messages should detect the chipset:

Dec  3 10:07:49 gbox Real Time Clock Driver v1.12ac
Dec  3 10:07:49 gbox Linux agpgart interface v0.101 (c) Dave Jones
Dec  3 10:07:49 gbox agpgart: Detected an Intel 965GM Chipset.
Dec  3 10:07:49 gbox agpgart: Detected 7676K stolen memory.
Dec  3 10:07:49 gbox agpgart: AGP aperture is 256M @ 0xe0000000
Dec  3 10:07:49 gbox [drm] Initialized drm 1.1.0 20060810

Maybe this is already solved when the xen dom0 sources move to 2.6.21

Could you check for sure which mainline kernel added the device? I'd rather take the time to finally roll a new kernel than start dropping in hardware patches.
Comment 2 Ralf Kaestner 2007-12-03 17:14:28 UTC
seems to be 2.6.21 if I interpret that correctly:
http://marc.info/?l=linux-kernel&m=117668200226118&w=2

can you confirm ??

If so you are of course correct that releaseing a new kernel makes more sense. You can close the bug and we have it as reference for anyone who needs a fast-fix. Is the xen gentoo kernel progress documented anywhere? I have some other issues with framebuffer and so I'm very interested in new (even beta) versions.

Yup, looks like it's in 2.6.21 then.

I'll leave this bug open and post a request for testing in here once i've got a new kernel, I'm not sure when that will be though. Should be some time this month.
