[PATCH 1/3] KVM: x86 emulator: warn when pin control is set in eventsel msr

Print warning once if pin control bit is set in eventsel msr since emulation does not support it yet. Signed-off-by: Gleb Natapov --- arch/x86/include/asm/perf_event.h |1 + arch/x86/kvm/pmu.c|3 +++ 2 files changed, 4 insertions(+), 0 deletions(-) diff --git a/arch/x86/

[PATCH 2/3] KVM: x86 emulator: Fix raw event check

If eventsel has EDGE, INV or CMASK set we should create raw counter for it, but the check is done on a wrong variable. Fix it. Signed-off-by: Gleb Natapov --- arch/x86/kvm/pmu.c |2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/x86/kvm/pmu.c b/arch/x86/kvm/pmu.c inde

[PATCH 3/3] KVM: x86 emulator: add proper support for fixed counter 2

Currently pmu emulation emulates fixed counter 2 as bus cycles architectural counter, but since commit 9c1497ea591b25d perf has pseudo encoding for it. Use it. Signed-off-by: Gleb Natapov --- arch/x86/kvm/pmu.c |3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/arch/x86/k

[PATCH] kvm: notify host when guest paniced

We can know the guest is paniced when the guest runs on xen. But we do not have such feature on kvm. This patch implemnts this feature, and the implementation is the same as xen: register panic notifier, and call hypercall when the guest is paniced. Signed-off-by: Wen Congyang --- arch/x86/kerne

[PATCH]qemu: deal with guest paniced event

When the host knows the guest is paniced, it will set exit_reason to KVM_EXIT_GUEST_PANIC. So if qemu receive this exit_reason, we can send a event to tell management application that the guest is paniced. Signed-off-by: Wen Congyang --- kvm-all.c |3 +++ linux-headers/linux/
