Paolo, is the branch open now for this kind of change? Where can I track
the branch status?

Newer versions of WHPX provide the capability to query the tsc
and apic frequency. Expose these through the vmware cpuid leaf.
This patch doesnt support setting the tsc frequency; that will
come as a separate fix.

Hey Paolo,
Following your suggestion of creating PRs for WHPX changes, I tried creating a
PR https://github.com/qemu/qemu/pull/95
But, I am getting repo-lockdown message. What do I need to do differently?
Thanks,

Until that support comes, use the QEMU values for the trapped CPUIDs.

TSC values as well that considers the VM state.
Additionally, while setting the TSC, the partition is suspended to
reduce the variance in the TSC value across vCPUs.

WHPX wasn't using the proper synchronization primitives while
processing async events, which can cause issues with SMP.

This refactors the load library of WHV libraries to make it more
modular. It makes a helper routine that can be called on demand.
This allows future expansion of load library/functions to support
functionality that is dependent on some feature being available.

Yes, we understand the concerns and I generally agree here. I am
trying to connect the different teams involved here (legal, SDK here)
and connect the dots for them, to see what can be done here.

Support for xcr0 to be able to enable xsave/xrstor. This by itself
is not sufficient to enable xsave/xrstor. WHPX XSAVE API's also
needs to be hooked up.
