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:
Not enabling x2APIC (upon firmware request)
...
mwait-idle: does not run on family 6 model 94
...
[VT-D] iommu.c:875: iommu_fault_status: Primary Pending Fault
[VT-D] INTR-REMAP: Request device [0000:f0:1f.0] fault index 0, iommu reg =
ffff82c000201000
(on motherboard 1) [VT-D] INTR-REMAP: reason 22 - Present field in the IRTE
entry is clear
(on motherboard 2) [VT-D] INTR-REMAP: reason 25 - Blocked a compatibility
format interrupt request
This leads to a few questions:
1) Is there some reason x2APIC should not be enabled on Skylake? What
consequence, if any, is there not having x2APIC enabled?
2) Should mwait-idle be available on Skylake?
3) What about the IOMMU errors on Skylake - are they a concern?
Thank you,
Eric

In this case, the firmware has set the x2apic opt-out bit in the DMAR
table, indicating that Xen should not use x2apic.
You might find an option in your BIOS to undo this; there have been
enough errata in the past in this area that I would expect it to be a
tweakable.
x2apic is the extension to xapic, which permits more than 255 cpus. So
long as you don't have that many, there isn't a specific problem with
missing x2apic mode.

We probably need to resync the mwait driver with Linux. It is
whitelisted on known cpu model numbers.
> 3) What about the IOMMU errors on Skylake - are they a concern?
Yes.
In both cases, PCI device f0:1f.0 is misconfigured or misbehaving.
On motherboard 1, it is delivering an interrupt for which no remapping
entry has been set up.
On motherboard 2, it is delivering an compatibility-format interrupt, as
opposed to a remapable-format interrupt.
For motherboard 2, Xen should disallow such a configuration. Either
interrupt remapping is enabled and all devices should be configured to
issue remmapable interrupts, or interrupt remapping is disabled and
everything should be configured to issue compatibility-format interrupts.
Either way, diagnosing the problem here starts with identifying what
f0:1f.0 is.

Eric, could you provide your motherboard information and as Andrew pointed out what’s f0:1f.0?

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: Intel Corporation Sunrise Point-H LPC Controller (rev
31)
At the moment, I am back on vanilla 4.6.0, and no such error messages are
being reported via 'xl dmesg'. I am guessing reporting of this error was
added post-4.6.

According to Andrew's comments. When disable an option called "X2APIC
Opt Out" in bios , the message will disappear.

Nothing obvious comes to mind which would have this effect.
Can you provide `lspci -tv` from one of the affected systems?
If the platform is generating interrupts from a non-existent device,
something is quite broken.

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

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.

As of 4.6.0 it actually takes a debug hypervisor to get those
messages logged (which arguably is wrong, and which quite
certainly is wrong for messages accompanying error returns).

So when I rebuild the hypervisor, it sounds like I should be doing a debug build?

With my current setup, it was easier for me to go back to 4.4.3.
Apparently the IOAPIC is at 0000:f0.1f.0. Output from 'xl dmesg'' is
attached.
