IGD Passthrough DMAR fault

Hello everyone,

I've been trying to get IGD passthrough working with any VM without success for a few days now.

I'm using a 6700k with Z170 AsRock itx motherboard.

VM is: win10, i440fx-2.7, seaBIOS, with intel HD Graphics 530

I get no errors in the VM log, but I do get an error in dmesg:

[  113.039814] DMAR: DRHD: handling fault status reg 2

[  113.039816] DMAR: [DMA Write] Request device [00:02.0] fault addr 0 [fault reason 02] Present bit in context entry is clear

[  113.556683] vfio_ecap_init: 0000:00:02.0 hiding ecap 0x1b@0x100

So far tried a few things:

- Disabled audio (errors with group 10)

- added to boot: intel_iommu=on iommu=pt

- added to boot: vfio_iommu_type1.allow_unsafe_interrupts=1 pcie_acs_override=downstream

- added to boot: video=vesafb:off,efifb:off blacklist=i915

I'm unsure what to try next, anyone have any suggestions?

(attached a few logs as well)
