Mon 14:22:13 UTC 2024 - Daniel Wagner <daniel.wagner@suse.com>
- Update to v1.8.0
  * remove: add-explicit-meson-thread-dependency.patch
  * tracefs_follow_event_clear() and tracefs_follow_missed_events_clear()
    API to clean up followers if the tracefs instance is going to be used
    for other iterations
  * tracefs_instance_file_write_number()
    A simple helper function to make it easier to write numbers into the
    tracefs files. It does the conversion from number to string, as the
    files expect strings and not numbers.
  * Add API to work with kbuffer, which gives more control to the application
    and speeds it up:
      tracefs_cpu_read_buf()
      tracefs_cpu_buffered_read_buf()
      tracefs_cpu_flush_buf()
   * tracefs_instance_get_buffer_percent() and tracefs_instance_set_buffer_percent()
     Modify the buffer_percent file that allows readers to block until the buffer
     is filled to a given percent. This keeps the reader from causing events that
     will add noise to the trace.
   * tracefs_instance_clear()
     Helper to clear the contents of the current trace instance.
   * tep_get_sub_buffer_data_size()
     Helper to retrieve the current sub-buffer data size. The Linux kernel tracing
     ring buffer is broken up into smaller sub-buffers. This returns the size of
     the data portion of those sub-buffers (does not include the sub-buffer meta
     data).
   * tracefs_load_headers()
     API to just load the information about the sub-buffers and nothing more.
   * API to extract tracing ring buffer statistics
       tracefs_instance_get_stat()
       tracefs_instance_put_stat()
       tracefs_buffer_stat_entries()
       tracefs_buffer_stat_overrun()
       tracefs_buffer_stat_commit_overrun()
       tracefs_buffer_stat_bytes()
       tracefs_buffer_stat_event_timestamp()
       tracefs_buffer_stat_timestamp()
       tracefs_buffer_stat_dropped_events
    * tracefs_instance_set_subbuf_size() and tracefs_instance_get_subbuf_size()
      API to modify the sub-buffers size of the tracing ring buffer.
    * Added TIMESTAMP_DELTA and TIMESTAMP_DELTA_USECS to tracefs_sql() as a shortcut
      for (end.TIMESTAMP - start.TIMESTAMP) and (end.TIMESTAMP_USECS - start.TIMESTAMP_USECS)
      respectively
    * Add PID filtering API:
        tracefs_filter_pid_function()
	tracefs_filter_pid_events()
        tracefs_filter_pid_function_clear()
        tracefs_filter_pid_events_clear()
    * Added tracefs_cpu_snapshot_open() to read the raw data of snapshot buffers
    * Added snapshot functions:
       tracefs_snapshot_snap()
       tracefs_snapshot_clear()
       tracefs_snapshot_free()
    * Added ring buffer memory mapping APIs
      tracefs_cpu_open_mapped()
      tracefs_cpu_is_mapped()
      tracefs_mapped_is_supported()
      tracefs_cpu_map()
      tracefs_cpu_unmap()
    * Updates:
      - Increase pipe max size to max value when using splice.
      - Clear "max_graph_depth" on tracefs_instance_reset()
      - Add missing headers to syscall() and SYS_* defines
      - Add dependency fixes to meson build
      - Fix some documentation / man page issues
      - Fix memory leaks
      - Fix cscope rule
      - Fix issues in unit tests
      - Added many more unit tests
