After converting perf.data to CTF, we lost pid-tid-comm mapping. Which makes inconvience. For example, in perf script output we know which process issue an event like this:
compiz 19361 [001] 3275709.313929: raw_syscalls:sys_exit: NR 7 = 0
After converting to CTF, we only get this:
[3275709.313929985] (+0.110646118) raw_syscalls:sys_exit: { cpu_id = 1 }, { perf_ip = 0xFFFFFFFF8107B2E8, perf_tid = 19361, perf_pid = 19361, perf_id = 18920, perf_period = 1, common_type = 16, common_flags = 0, common_preempt_count = 1, common_pid = 19361, id = 7, ret = 0 }
Currently, if we want to find the name and parent of a process, we have to collect 'sched:sched_switch' event.
This patch set adds a '--all' option to 'perf convert', converts comm, fork and exit events to CTF output. CTF user now can track the mapping by their own.
v1 -> v2: Report number of sample and non-sample events when finish. rename opts.non_sample to opts.all.
Wang Nan (7): perf ctf: Add value_set_string() helper perf ctf: Pass convert options through opts structure perf ctf: Add 'all' option perf ctf: Prepare collect non-sample events perf ctf: Generate comm event to CTF output perf ctf: Add '--all' option for 'perf data convert' perf ctf: Generate fork and exit events to CTF output
