perf test: Add test case for pmu event new style format
Add test case in automated tests suite. It checks not only the two types
of pmu event stytle formats "pmu_event_name" and "cpu/pmu_event_name/",
but also the different formats mixtures which are more likely to trigger
parse issue.
The patch set including this one has been tested by the perf automated
test:
./perf test parse -v"
On haswell, ivybridge and Romley platform.
The patch set also has been tested on haswell by the following script.
Note: please make sure that your test system support TSX and
L1-dcache-loads events. Otherwise, you may want to change the events to
other pmu events.
[lk@localhost ~]$ cat perf_style_test.sh
# hardware events + kernel pmu event with different style
perf stat -x, -e cycles,mem-stores,tx-start sleep 2
perf stat -x, -e cpu-cycles,cycles-ct,cycles-t sleep 2
perf stat -x, -e cycles,cpu/cycles-ct/,cpu/cycles-t/ sleep 2
perf stat -x, -e instructions,cpu/tx-start/ sleep 2
perf stat -x, -e '{cycles,tx-start}' sleep 2
perf stat -x, -e '{cycles,cpu/tx-start/}' sleep 2
# HW Cache event + kernel pmu event with different style

perf stat -x, -e L1-dcache-loads,mem-stores,cpu/tx-start/ sleep 2
perf stat -x, -e '{L1-dcache-loads,mem-stores}' sleep 2
perf stat -x, -e '{L1-dcache-loads,cpu/tx-start/}' sleep 2
# Raw event + kernel pmu event with different style:
perf stat -x, -e cpu/event=0xc0,umask=0x00/,mem-loads,cpu/mem-stores/ sleep 2
perf stat -x, -e cpu/event=0xc0,umask=0x00/,tx-start,cpu/el-start/ sleep 2
perf stat -x, -e '{cpu/event=0xc0,umask=0x00/,tx-start}' sleep 2
