wheezy VT-d passthrough test: DMAR:[fault reason 06h] PTE Read access is not set
lspci -vvv and -t attached
Serial console output: http://pastebin.ca/2177395
Main error appears to be:
(XEN) [VT-D]iommu.c:858: iommu_fault_status: Primary Pending Fault
(XEN) [VT-D]iommu.c:833: DMAR:[DMA Read] Request device [00:1e.0]
fault addr df8e5000, iommu reg = ffff82c3fff57000
(XEN) DMAR:[fault reason 06h] PTE Read access is not set
onboard nic on the same bus is going down as depicted in the console log
non-vtd passthrough to pv appears to work fine (shows up on domU lspci,
did not run a hardware test)

Additional information: I just checked the hvm and saw that the passthrough actually succeeds. Windows wants to install a driver for the tuner. So there is the iommu fault and onboard nic issue. The serial card is on the same bus, but seems unaffected. Attached more logs. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
