  • 040f9915e   perf data: Add perf_data_file__switch() helper ... Browse Code »

    perf_data_file__switch() closes current output file, renames it, then
    open a new one to continue recording. It will be used by 'perf record'
    to split output into multiple perf.data files.

  • 6f9a317f2   perf tools: Add perf_data_file__write interface ... Browse Code »

    Adding perf_data_file__write interface to centralize output to files.
    The function prototype is:

    ssize_t perf_data_file__write(struct perf_data_file *file,
    void *buf, size_t size);

    Returns number of bytes written or -1 in case of error.

    NOTE: Also indenting 'struct perf_data_file' members, no functional
    change done.

  • f5fc14124   perf tools: Add data object to handle perf data file ... Browse Code »

    This patch is adding 'struct perf_data_file' object as a placeholder for
    all attributes regarding perf.data file handling. Changing
    perf_session__new to take it as an argument.

    The rest of the functionality will be added later to keep this change
    simple enough, because all the places using perf_session are changed
    now.
