[PATCH 14/16] perf kvm/powerpc: Port perf kvm stat to powerpc

See http://www.infradead.org/rpr.html From: Hemant Kumar perf kvm can be used to analyze guest exit reasons. This support already exists in x86. Hence, porting it to powerpc. - To trace KVM events : perf kvm stat record If many guests are running, we can track

[PATCH 13/16] perf kvm/{x86,s390}: Remove const from kvm_events_tp

See http://www.infradead.org/rpr.html From: Hemant Kumar This patch removes the "const" qualifier from kvm_events_tp declaration to account for the fact that some architectures may need to update this variable dynamically. For instance, powerpc will need to update

[PATCH 12/16] perf kvm/{x86, s390}: Remove dependency on uapi/kvm_perf.h

From: Hemant Kumar Its better to remove the dependency on uapi/kvm_perf.h to allow dynamic discovery of kvm events (if its needed). To do this, some extern variables have been introduced with which we can keep the generic functions generic. Signed-off-by: Hemant Kumar

[PATCH 15/16] perf kvm/powerpc: Add support for HCALL reasons

From: Hemant Kumar Powerpc provides hcall events that also provides insights into guest behaviour. Enhance perf kvm stat to record and analyze hcall events. - To trace hcall events : perf kvm stat record - To show the results : perf kvm stat report
