2014-12-17KVM: PPC: Book3S HV: Tracepoints for KVM HV guest interactionsSuresh E. Warrier1-0/+32
This patch adds trace points in the guest entry and exit code and also for exceptions handled by the host in kernel mode - hypercalls and page faults. The new events are added to /sys/kernel/debug/tracing/events under a new subsystem called kvm_hv.
