| |
To analyze the exit events with perf, we need kvm_perf.h to be added in the arch/powerpc directory, where the kvm tracepoints needed to trace the KVM exit events are defined.
This patch adds "kvm_perf_book3s.h" to indicate that the tracepoints are book3s specific. Generic "kvm_perf.h" then can just include "kvm_perf_book3s.h".
Signed-off-by: Hemant Kumar <hemant@linux.vnet.ibm.com> --- Changes: - Not exporting the exit reasons compared to previous patchset (suggested by Paul)
