Re: [Xen-users] VGA Passthrough

["Rome Pierce" <romep@xxxxxx>]

Hello,

i think it has something to do with this:

(XEN) [VT-D]iommu.c:821: iommu_fault_status: Fault Overflow
(XEN) [VT-D]iommu.c:824: iommu_fault_status: Primary Pending Fault
(XEN) [VT-D]iommu.c:799: DMAR:[DMA Write] Request device [00:02.0] fault addr 
ffffff000, iommu reg = ffff82c3fff56000
(XEN) DMAR:[fault reason 05h] PTE Write access is not set
(XEN) print_vtd_entries: iommu = ffff830137cf8950 bdf = 0:2.0 gmfn = ffffff
(XEN)     root_entry = ffff830137c3b000
(XEN)     root_entry[0] = 7737001
(XEN)     context = ffff830007737000
(XEN)     context[10] = 1_80fe001
(XEN)     l3 = ffff8300080fe000
(XEN)     l3_index = 3f
(XEN)     l3[3f] = 0
(XEN)     l3[3f] not present


VT-d is supported and enabled in bios. Kernel Parameter are vtd=1 and 
intel_iommu=on
