The problem wasn't with xen iommu support but kms/drm and i915 driver.
Passing to the kernel i915.preliminary_hw_support=1 fixes it all :)
Thanks

Sorry about that (and repost since I wrote the same misleading post to two
places)

If you have any hint, please contribute :)
Help me say happy new years to all security conscious people out there :)

Hey devs,
Thinkpad x200 p8600 laptops have vt-d, vt-x and tpm. They also have intel
integrated graphics 4 Series (gm45 chipset), supported through i915 driver.
In December, a fix got introduced to Xen 4.6 through iommu=no-igfx switch.
Before that fix, it was impossible to boot xen without passing
candidate for
Qubes.

The case is 1) disabling iommu for IGD, unilaterally since i915 + gm45
doesn't play well together. Iommu is still desired to isolate usb and
network devices, so we don't want to disable iommu completely. The side
effect of this would be to have IGD only for dom0, which would also
completely make se
Only dom0 talks directly to the i915 driver, other appvm being pv, which is
why I put in question the complete deactivation of IGD by iommu=no-igfx.
Is there anything I can provide to troubleshoot?

It seems that IGD iommu is not completely deactivated, yes, since memory
corruption happens (graphic glitches and then system hang)
General iommu is still reported as being active by xen, as desired.
