kvm powerpc/book3s-apiv2: Introduce kvm-hv specific PMU
Introduce a new PMU named 'kvm-hv' inside a new module named 'kvm-hv-pmu' to report Book3s kvm-hv specific performance counters. This will expose KVM-HV specific performance attributes to user-space via kernel's PMU infrastructure and would enableusers to monitor active kvm-hv based guests. The patch creates necessary scaffolding to for the new PMU callbacks and introduces the new kernel module name 'kvm-hv-pmu' which is built with CONFIG_KVM_BOOK3S_HV_PMU. The patch doesn't introduce any perf-events yet, which will be introduced in later patches Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> Signed-off-by: Madhavan Srinivasan <maddy@linux.ibm.com> Link: https://patch.msgid.link/20250416162740.93143-5-vaibhav@linux.ibm.com
