• A
    perf session: Parse sample earlier · 640c03ce
    Arnaldo Carvalho de Melo 提交于
    At perf_session__process_event, so that we reduce the number of lines in eache
    tool sample processing routine that now receives a sample_data pointer already
    parsed.
    
    This will also be useful in the next patch, where we'll allow sample the
    identity fields in MMAP, FORK, EXIT, etc, when it will be possible to see (cpu,
    timestamp) just after before every event.
    
    Also validate callchains in perf_session__process_event, i.e. as early as
    possible, and keep a counter of the number of events discarded due to invalid
    callchains, warning the user about it if it happens.
    
    There is an assumption that was kept that all events have the same sample_type,
    that will be dealt with in the future, when this preexisting limitation will be
    removed.
