Re: [Xen-devel] Skylake: VT-d and other error messages

I have attached the output from 'xl dmesg' with iommu=debug apic_verbosity=debug loglvl=all This is with 4.6.0, with the recent patch enabling mwait-idle on Skylake applied. My initial post was running the latest out of xen.git master. I may be able to try to newer code again later this week.

Re: [Xen-devel] Skylake: VT-d and other error messages

ASRock Z170 Extreme 4 with BIOS version 2.30 was motherboard #1 Gigabyte GA-Z170XP-SLI with BIOS version F5 was motherboard #2 As I initially reported, both were reporting the error involving f0:1f.0 Not surprisingly, there are no f0:xx.y devices. The closest I suppose is: 00:1f.0 ISA Bridge:

Looking through the output of 'xl dmesg' on a Skylake system (i5-6600K), I found a number of error messages that I do not encounter on a Haswell-based system. I have tried two motherboards from different manufacturers, with pretty much the same results. Below are some of the unexpected messages:
