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.

Did you also check "iommu=verbose" output for occurrences of this
ID (e.g. representing an IO-APIC or HPET)?
