From f15a75eedc18e1fece8e01f1a6f7d135e61b0750 Mon Sep 17 00:00:00 2001 From: Wanpeng Li <wanpeng.li@hotmail.com> Date: Tue, 30 Aug 2016 16:14:01 +0800 Subject: KVM: nVMX: make emulated nested preemption timer pinned MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 61abdbe0bc ("kvm: x86: make lapic hrtimer pinned") pins the emulated lapic timer. This patch does the same for the emulated nested preemption timer to avoid vmexit an unrelated vCPU and the latency of kicking IPI to another vCPU.
