Hi,
when comparing the dmesgs from a Ubuntu 11.04+xorg-edgers-ppa running on real
hardware ver. running in a HVM-domU, I see this change in dmesg:
real:
[ 2.306326] [drm:intel_wait_for_vblank], vblank wait timed out
[ 2.307140] [drm:gen6_fdi_link_train], FDI_RX_IIR 0x700
[ 2.307143] [drm:gen6_fdi_link_train], FDI train 1 done.
[ 2.307798] [drm:gen6_fdi_link_train], FDI_RX_IIR 0x600
[ 2.307801] [drm:gen6_fdi_link_train], FDI train 2 done.
[ 2.307802] [drm:gen6_fdi_link_train], FDI train done.
domU:

[ 3.658962] [drm:gen6_fdi_link_train], FDI_RX_IIR 0x700

[ 3.660633] [drm:gen6_fdi_link_train], FDI_RX_IIR 0x0

[ 3.661140] [drm:gen6_fdi_link_train] *ERROR* FDI train 2 fail!
[ 3.661142] [drm:gen6_fdi_link_train], FDI train done.
The desktop looks OK on real hardware.
In a domU the display shows 'no signal' and turns it self off during
the boot process.
The domU stays up and does not crash, oops, seg-faults, etc.
I've tried
chvt 1 / 7
xset dpms force off / on
xrandr --off / --auto
with no visible change.
Hardware:
DQ67SW (vt-d enabled)
i5 2400
Display connected via DVI-D / DVI-I+VGA adapter
Software:
domU kernel: 3.1.0-rc3 x86 32 bit
dom0 kernel: 3.0.3
(git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git) x86_64
xen 4.2-unstable (xen_changeset : Thu Aug 25 12:03:14 2011
+0100 23791:227130622561)
A short test with openSUSE-NET-Build0136-x86_64.iso shows the same behaviour.
On the other hand, XP-SP3 with the GFX_XP32_6.14.10.5361_PV.exe works
quite well with the same configuration.
Thanks,
Martin

An you have CONFIG_DMAR enabled?

That is pretty neat.

Hm, this might be a symptom of an earlier error in the boot process I
hadn't noticed last week:
real:

[drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
[drm] Driver supports precise vblank timestamp query.
[drm:parse_general_definitions], crt_ddc_bus_pin: 5
By searching for "opregion signature mismatch" I found in intel_opregion.c:
#define OPREGION_SIGNATURE "IntelGraphicsMem"
[..]
pci_read_config_dword(dev->pdev, PCI_ASLS, &asls);
DRM_DEBUG_DRIVER("graphic opregion physical addr: 0x%x\n", asls);
if (asls == 0) {
DRM_DEBUG_DRIVER("ACPI OpRegion not supported!\n");
return -ENOTSUPP;
}
base = acpi_os_ioremap(asls, OPREGION_SIZE);
if (!base)
return -ENOMEM;
if (memcmp(base, OPREGION_SIGNATURE, 16)) {
DRM_DEBUG_DRIVER("opregion signature mismatch\n");
err = -EINVAL;
goto err_out;
}
On the xen side(/var/log/xen/qemu-dm-domU.log) I see:
register_vga_regions: register_vga: igd_opregion = bc8d6018

Is "can't open file /dev/xen/pci_iomul" a real problem?
I'm not sure where to go from here...

Yes, CONFIG_DMAR is set to 'y' for the dom0.
