VT-d faults with Integrated Intel graphics on 4.6

VT-d faults with Integrated Intel graphics on 4.6

Hi everyone,
I saw some people passingly mention this on the list before but just in
case it has been missed, my serial is also being spammed with the following
printouts with both Xen 4.6 RC1 and the latest staging build:

...
(XEN) [VT-D]DMAR:[DMA Read] Request device [0000:00:02.0] fault addr
33487d7000, iommu reg = ffff82c000201000
(XEN) [VT-D]DMAR: reason 06 - PTE Read access is not set
(XEN) [VT-D]DMAR:[DMA Read] Request device [0000:00:02.0] fault addr

(XEN) [VT-D]DMAR: reason 07 - Next page table ptr is invalid
...

The device in question is an integrated Intel graphics card:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)

The only way I found to stop the messages from making my serial connection
useless was by assigning the device to xen-pciback.

Cheers,
Tamas

What's your platform? BDW? And how much memory is set to your guest OS?

Just at first glance to fault address, this seems be issued from some 
known erratas on BDS and SKL.

Is see this as well. But oddly enough - only when I use the AMT feature
(normally I just use serial console on the machine).

The platform is             /DQ67SW, BIOS
SWQ6710H.86A.0066.2012.1105.1504 11/05/2012

There is no guest OS - this is initial domain. And I boot with 2GB:

Same board for mine and same BIOS version. I'm also using the serial
through AMT. This is showing up for dom0 without any guests. Dom0 however
has a max memory set to 4GB. This is my Xen boot param:

dom0_mem=4096M,max:4096M dom0_max_vcpus=4 dom0_vcpus_pin=true hap_1gb=false
hap_2mb=false loglvl=all guest_loglvl=all sync_console console_to_ring
com1=115200,8n1,amt console=com1 intel_iommu=on

I think this problem is caused by missing IOMMU mappings for the RMRR regions
if the domain does not have shared EPT enabled. This includes PV Dom 0.

I have posted a patch to fix the issue:

This is a sandy bridge device which doesn't support shared EPT for GPU device.

This will cause the GPU to be reset and the reset stopped the GPU accessing the
RMRR region.

This faulting address is higher than top of ram as reported in the
e820.  Xen has legitimately not created IOMMU pagetables to map that
physical address.

Looks like something has programmed the GPU with a duff GTT.  I suspect
a firmware bug.

As you see those fault addresses are out of the normal memory range  here.

So I really doubt this is related to some erratas. Currently the 
pre-fetch unit of IOMMU unit dedicated to IGD can't work well on some 
platforms, so you can see these wired faults.

I don't think this is relevant to current problem.
