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.
V2:
* Create a generic pmu.c file which is shared by Intel and AMD CPUs;
* pmu.c code becomes part of kvm.ko module. Similarly pmu_intel.c and
pmu_amd.c are linked to kvm-intel.ko and kvm-amd.ko respectively;
* Re-define kvm_pmu_ops function pointers. Per Radim Krcmar's comments,
a large portion of Intel vPMU code are now consolidated and moved to
pmu.c;
* Polish pmu_amd.c code to comply with new definition of kvm_pmu_ops;
It doesn't apply on top of current kvm queue, I'll have cosmetic change
requests that would go well with a rebase.
Sorry about it. It was applied on top of Linux 4.0-rc6 (e42391cd04880).
