Currently KVM only supports vPMU for Intel platforms. This patch set enable vPMU support for AMD platform by creating a common PMU interface for x86. The PMU calls from guest VMs are dispatched to corresponding functions defined in arch specific files. V1: * Adopt the file layout suggested by Radim Krčmář * Link arch module with its specific PMU file RFC: * Initial version for RFC Wei Huang (4): KVM: x86/vPMU: Define kvm_pmu_ops to support vPMU function dispatch KVM: x86/vPMU: Convert pmu.c code into Intel specific code KVM: x86/vPMU: Implement AMD PMU support for KVM KVM: x86/vPMU: Enable PMU handling for AMD PERFCTRn and EVNTSELn MSRs arch/x86/include/asm/kvm_host.h | 52 ++-- arch/x86/kvm/Makefile | 6 +- arch/x86/kvm/cpuid.c | 2 +- arch/x86/kvm/lapic.c | 1 + arch/x86/kvm/pmu.c | 576 --------------------------------------- arch/x86/kvm/pmu_amd.c | 390 ++++++++++++++++++++++++++ arch/x86/kvm/pmu_intel.c | 586 ++++++++++++++++++++++++++++++++++++++++ arch/x86/kvm/svm.c | 7 + arch/x86/kvm/vmx.c | 7 + arch/x86/kvm/x86.c | 74 ++--- 10 files changed, 1070 insertions(+), 631 deletions(-) delete mode 100644 arch/x86/kvm/pmu.c create mode 100644 arch/x86/kvm/pmu_amd.c create mode 100644 arch/x86/kvm/pmu_intel.c -- 1.8.3.1 -- 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
