Oh, I forgot this. I'll check the nested TSC scaling code (mostly
about nested SVM TSC ratio, because t
Did you consider nested virtualization?
L1 hypervisor may have a different tsc scaling
and L2 guest again may have a different tsc scale ratio.

I have tested this patchset on both Intel and AMD systems.
For the test on AMD systems, I made two rounds of tests. The first
round only applied bug-fix patches 1-6. The second round applied the
entire series. In both rounds, I used the test process at

This patchset adds support for VMX TSC scaling feature which is
available on Intel Skylake Server CPU. The specification of VMX TSC
scaling can be found at

VMX TSC scaling allows guest TSC w
