After aa297292d708, there are separate native calibrations for cpu_khz and tsc_khz. The code sets x86_platform.calibrate_cpu to native_calibrate_cpu() which looks in cpuid leaf 0x16 or msrs for the cpu frequency. Since we keep the tsc_khz constant (even after vmotion), the cpu_khz and tsc_khz may start diverging. tsc_init() now does cpu_khz = x86_platform.calibrate_cpu(); tsc_khz =

Hello, This patchset introduces steal time accounting support for the VMware guest. The idea and implementation of guest steal time support is similar to KVM ones and it is based on steal clock. The steal clock is a per CPU structure in a shared memory between hypervisor and guest, initialized by each CPU through hypercall. Steal clock is got updated by the hypervisor and read by the guest. The
