My 100 series skylake / i5 6600k doesn't support apicv and used to have
x2apic off by default. A recent bios update however switched x2apic on
whilst also (finally) providing the cpu firmware bug fix. Consistent
with the claims in this thread however I found I have to add nox2apic on
my kernel
Well, then that would lend credence to it not being a Warden thing. Unless
Warden is implemented significantly differently across Blizzard's various
games.

Actually, I also haven't seen further ones while I'm playing Overwatch.
Just at startup. I wonder if maybe I've got something misconfigured?

Thanks, I guess the "issue" is only from the blizzard games. It could very
well be that this is used as some anti-tamper tool in these blizzard games,
but I find it odd that it only does this in Win10 and that returning 0
doesn't cause a problem.

I've only seen it call them at startup. After playing for an hour or so, I
didn't see more of them in my dmesg output.

For what its worth it seems Rise of the Tomb Raider also calls it, so it
might be Denuvo.
The interesting thing is Rise of the Tomb Raider only calls it once. So
there is no performance issue. Heroes and Starcraft continuously make these
calls which causes the performance issue.
Can anyone confir
They have the warden which is constantly checking your system

I don't think Blizzard uses Denuvo.

I am able to passthrough a nvidia card (tried both 630 and 950) to a
windows 10 guest, but once I install the nvidia driver in windows I
start getting a blue screen and the vm reboots constantly saying system
thread exception not handled (nvlddmkm.sys). I have also tried windows
7, but I'm stil

LGA 2011-3 Processors like your Ci7 5930K are Haswell-E, NOT standard Haswell,
they are not the same. There may be Core
I struggled with the rare (but very annoying) crackles and finally I don't
have them anymore with emulated audio.
I use cpu isolation and keep 2 CPU threads for host out of 8.
I use MSI as per alex's VFIO blog.
I pass following env to qemu:
QEMU_AUDIO_DRV=pa
QEMU_PA_SAMPLES=1024
PULSE_COOKIE=/hom
Yes, this is a win10 issue.
Changing the Virtual CPU model does not make a difference. Each model has
its own LBR register address, but one will be called.
The only thing I have not tried is using an AMD processor. AMD CPUs support
lbrv which is virtualization of the LBR registers, so it is handle
As of updating to kernel 4.5.4-1-vfio ( from 4.4.5-1-vfio ) am having a
strange issue in qemu (2.6.0) with my USB controller pass-through only
working once per host boot. Also interesting to note that my Nvidia HDMI
audio only works when the USB controller is not. The Nvidia HDMI audio
never worked
2 things:
- this msrs are not called from StarCraft on Win8.1.
- i wonder if forcing virtual CPU model to something older will disable
them in Win10.
This msrs issue is what holds me off upgrade to W10.

With Ivy Bridge-E, Intel introduced their APIC Virtualization extension, APICv
(Rather contradictory, on other sources its called vAPIC). APICv seems to be
built on top of x2APIC, so it requires it to be working on the host to be used.
You can check that in the host by using:
dmesg | grep x2apic
17 matches
