Subject[PATCH v2 0/2] if running under KVM, use kvmclock to compute TSC deadline value
Date
v1 posted here: https://patchwork.kernel.org/patch/9214993/

The motivation for this patch is in patch 2 (or you can read it from v1).

This version is larger but the hooks into apic.c are cleaner than in
v1. Instead of arranging for kvmclock to replace only a small part of
setup_apic_timer, it registers its own clockevent. The downside is that
kvmclock now needs to hook into the LAPIC timer interrupt to invoke the
event_handler of the new clockevent, but this is pretty straightforward
with a new pvop (assuming the introduction of new pvops is straightforward
at all).

Thanks,

Paolo
