[PATCH 15/20] hyperv: Support hv-time enlightenment

6 Oct 2025

From: Michal Privoznik <mprivozn@redhat.com>

QEMU supports this enlightenment since version 2.0. It's required
by some other enlightenments (e.g. hv-stimer, hv-stimer-direct).
From QEMU docs:

``hv-time``
  Enables two Hyper-V-specific clocksources available to the guest: MSR-based
  Hyper-V clocksource (HV_X64_MSR_TIME_REF_COUNT, 0x40000020) and Reference TSC
  page (enabled via MSR HV_X64_MSR_REFERENCE_TSC, 0x40000021). Both clocksources
  are per-guest, Reference TSC page clocksource allows for exit-less time stamp
  readings. Using this enlightenment leads to significant speedup of all timestamp
  related operations.
