perf/x86: Add hardware events translations for Intel P6 cpus
Add support for Intel P6 processors to display 'events' sysfs directory (/sys/devices/cpu/events/) with hw event translations: # ls /sys/devices/cpu/events/ branch-instructions branch-misses bus-cycles cache-misses cache-references cpu-cycles instructions ref-cycles stalled-cycles-backend stalled-cycles-frontend Suggested-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Vince Weaver <vincent.weaver@maine.edu> Cc: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Cc: Paul Mackerras <paulus@samba.org> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1349873598-12583-6-git-send-email-jolsa@redhat.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
