The Sleep command is "sleep.coreutils" in Yocto project, so
the command mmap filename is "sleep.coreutils" in perf test
6. Strncmp() can get the right result.
Before:
# perf test -v 6
6: Validate PERF_RECORD_* events & perf_sample fields :
--- start ---
test child forked, pid 31717
mmap size 1052672B
588401125676220 0 PERF_RECORD_SAMPLE
...
588402126709180 0 PERF_RECORD_EXIT(31718:31718):(31718:31718)
PERF_RECORD_MMAP for sleep missing!
test child finished with -1
---- end ----
Validate PERF_RECORD_* events & perf_sample fields: FAILED!
After:
# perf test -v 6
6: Validate PERF_RECORD_* events & perf_sample fields :
--- start ---
test child forked, pid 31725
mmap size 1052672B
588588715789540 0 PERF_RECORD_SAMPLE
...
588589716825180 0 PERF_RECORD_EXIT(31726:31726):(31726:31726)
test child finished with 0
---- end ----
Validate PERF_RECORD_* events & perf_sample fields: Ok
