perf has perf-completion.sh to define command line auto-completion in
bash/zsh.
For record/stat -e it works for single events, but isn't working when
specifying multiple events with comma.
It would be very useful if it could be fixed to make it easier by
supporting multiple events, comma separated.
With this patch, the result can be like this:
1. Support the events returned from 'perf list --raw-dump'
root@skl:/tmp# perf stat -e cpu/cache<TAB>
cpu/cache-misses/ cpu/cache-references/
root@skl:/tmp# perf stat -e cpu/cache-misses/,cpu/branch-<TAB>
cpu/branch-instructions/ cpu/branch-misses/
root@skl:/tmp# perf stat -e cpu/cache-misses/,cpu/branch-i<TAB>
root@skl:/tmp# perf stat -e cpu/cache-misses/,cpu/branch-instructions/
2. Support the events listed in /sys/bus/event_source/devices/cpu/events
root@skl:/tmp# perf stat -e cycle<TAB>
cycle_activity.cycles_l1d_miss cycle_activity.stalls_l3_miss
cycle_activity.cycles_l2_miss cycle_activity.stalls_mem_any
cycle_activity.cycles_l3_miss cycle_activity.stalls_total
cycle_activity.cycles_mem_any cycles-ct
cycle_activity.stalls_l1d_miss cycles-t
cycle_activity.stalls_l2_miss
root@skl:/tmp# perf stat -e cycles-<TAB>
cycles-ct cycles-t
root@skl:/tmp# perf stat -e cycles-t,cpu/c<TAB>
cpu/cache-misses/ cpu/cpu-cycles/ cpu/cycles-t/
cpu/cache-references/ cpu/cycles-ct/
root@skl:/tmp# perf stat -e cycles-t,cpu/cache-<TAB>
cpu/cache-misses/ cpu/cache-references/
root@skl:/tmp# perf stat -e cycles-t,cpu/cache-misses/
3. Support the uppercase event which is with prefix "cpu/"
root@skl:/tmp# perf stat -e cpu/c<TAB>
cpu/cache-misses/ cpu/cpu-cycles/ cpu/cycles-t/
cpu/cache-references/ cpu/cycles-ct/
root@skl:/tmp# perf stat -e cpu/cache-misses/,cpu/C<TAB>
cpu/CACHE-MISSES/ cpu/CPU-CYCLES/ cpu/CYCLES-T/
cpu/CACHE-REFERENCES/ cpu/CYCLES-CT/
root@skl:/tmp# perf stat -e cpu/cache-misses/,cpu/CACHE-REFERENCES/
Note that:
a) This patch only supports bash.
b) It doesn't support the cases like {},{} or {...,...}.
