Hi,
this is the third round of my patches to support tsc-scaling in KVM. The
changes to v2 address Avi's comments from yesterday. Besides that the
whole virtual_tsc_khz thing has been moved out of the vm into the vcpu
data structure. The mult and shift parts where renamed to tsc_catchup_*
because this is their actual use (and because the handling of
virtual_tsc_khz has changed so that is made sense to seperate them).
Comments and feedback (or merging) appreciated :-)
Regards,
Joerg
