>From 946e7589e5a875574c7567a91943d47c38218a6f Mon Sep 17 00:00:00 2001 From: Quan Xu Date: Fri, 14 Apr 2017 02:11:30 +0800 Subject: [PATCH v1] vmx: set 'SN' bit for the runstate transition from blocked to runnable set 'SN' bit of posted-interrupt descriptor when the runstate transition is from blocked to runnable (SN bit of posted-interrupt descriptor is still set to a blocked vCPU), otherwise PI notification event may be sent to a non-running vCPU.
