2018-07-24perf stat: Get rid of extra clock display functionJiri Olsa
There's no reason to have separate function to display clock events. It's only purpose was to convert the nanosecond value into microseconds. We do that now in generic code, if the unit and scale values are properly set, which this patch do for clock events. The output differs in the unit field being displayed in its columns rather than having it added as a suffix of the event name. Plus the value is rounded into 2 decimal numbers as for any other event. Before: # perf stat -e cpu-clock,task-clock -C 0 sleep 3 Performance counter stats for 'CPU(s) 0': 3001.123137 cpu-clock (msec) # 1.000 CPUs utilized 3001.133250 task-clock (msec) # 1.000 CPUs utilized 3.001159813 seconds time elapsed Now: # perf stat -e cpu-clock,task-clock -C 0 sleep 3 Performance counter stats for 'CPU(s) 0': 3,001.05 msec cpu-clock # 1.000 CPUs utilized 3,001.05 msec task-clock # 1.000 CPUs utilized 3.001077794 seconds time elapsed There's a small difference in csv output, as we now output the unit field, which was empty before.

2018-07-24perf stat: Add transaction flag (-T) support for s390Thomas Richter
The 'perf stat' command line flag -T to display transaction counters is currently supported for x86 only. Add support for s390. It is based on the metrics flag -M transaction using the architecture dependent JSON files. This requires a metric named "transaction" in the JSON files for the platform. Introduce a new function metricgroup__has_metric() to check for the existence of a metric_name transaction. As suggested by Andi Kleen, this is the new approach to support transactions counters. Other architectures will follow. Output before: [root@p23lp27 perf]# ./perf stat -T -- sleep 1 Cannot set up transaction events [root@p23lp27 perf]# Output after: [root@s35lp76 perf]# ./perf stat -T -- ~/mytesttx 1 >/tmp/111 Performance counter stats for '/root/mytesttx 1': 1 tx_c_tend # 13.0 transaction 1 tx_nc_tend 11 tx_nc_tabort 0 tx_c_tabort_special 0 tx_c_tabort_no_special 0.001070109 seconds time elapsed [root@s35lp76 perf]# Suggested-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Hendrik Brueckner <brueckner@linux.ibm.com> Acked-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Link: http://lkml.kernel.org/r/20180626071701.58190-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
