    Subject[PATCH v2 0/7] perf ctf: Convert comm, fork and exit events to CTF
    Date
    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
