OK, this is an AMD IOMMU box. [ 0.000000] ACPI: IVRS 00000000cfcf9830 000E0 (v01 AMD RD890S 00202031 AMD 00000000) It's discovered and enalbed properly: [ 0.698992] AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40 [ 0.710287] AMD-Vi: Lazy IO/TLB flushing enabled > Does anybody know the debug kernel switches for iommu? Two helpful kernel commandline options are: amd_iommu_dump debug (and drop "quiet") The problem is when you attach the device (function) you're getting stuck up in conflicts with the existing domain for that function. My guess is that all the functions are behind a PCI to PCI bridge, so the alias lookup is finding a conflict. thanks, -chris -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
