Original description:
TSC calibration on virtual machines is always error prone. It was found that in nested environments Gen2 instances may get stuck on boot. As Hyper-V hosts provide us with all the required information we can easily avoid calibration. This is already done for other hypervisors (KVM, Vmware).
Vitaly Kuznetsov (2): hyper-v: check frequency MSRs presence according to the specification hyper-v: read TSC frequency from a synthetic MSR
