Async pagefaults should only be injected into L1 guests. This series tries to make certain that async_pfs are not injected when L2 is executing on a vCPU, but also that L2 exits to L1 as soon as there are ready pages, to allow L1 to make better scheduling decisions. Roman Kagan (5): kvm/x86: skip async_pf when in guest mode 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 Signed-off-by: Roman Kagan <rkagan@xxxxxxxxxxxxx> --- v1 -> v2: - dropped bogus patch for async_pf msr check - included patch to skip async_pf in guest mode as it disappeard from kvm/queue - avoid breaking s390 build in patch 3 include/linux/kvm_host.h | 7 +++++++ arch/x86/kvm/mmu.c | 2 +- arch/x86/kvm/svm.c | 10 ++++++++++ arch/x86/kvm/vmx.c | 9 +++++---- arch/x86/kvm/x86.c | 5 +++-- virt/kvm/async_pf.c | 8 ++++++-- 6 files changed, 32 insertions(+), 9 deletions(-) -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
