Subject: [PATCH 0/5] kvm: avoid delaying async_pf ready delivery
Date: Fri, 2 Dec 2016 11:47:49 +0300	[thread overview]
Message-ID: <20161202084754.22860-1-rkagan@virtuozzo.com> (raw)

Make the guest immediately aware of async_pf's being resolved, to
prevent it from holding off higher priority tasks in favor of lower
priority ones, including nested guests.

Roman Kagan (5):
  kvm/x86: fix inversed check for async_pf MSR
  kvm: add helper for testing ready async_pf's
  kvm: kick vcpu when async_pf is resolved
  kvm/vmx: kick L2 guest to L1 by ready async_pf
  kvm/svm: kick L2 guest to L1 by ready async_pf
