This makes FreeBSD guest to not avoid using LAPIC timer, preferring HPET due to worries about non-existing for virtual CPUs deep sleep states. Benchmarks of usleep(1) on guest and host show such extra latencies: - 51us for virtual HPET, - 22us for virtual LAPIC timer, - 22us for host HPET and - 3us for host LAPIC timer. diff 280839 Mon Mar 30 05:21:00 MDT 2015 mav MFC r280134: Report ARAT (APIC-Timer-always-running) feature for virtual CPU.
