Changelog for
libtracefs1-1.8.1-lp155.2.1.x86_64.rpm :
* Sat Jul 27 2024 Jan Engelhardt
- Update to release 1.8.1
* Plug some memory leaks- Delete 0001-libtracefs-meson-build-tracefs-mmap-by-default.patch (merged)
* Mon Jun 17 2024 Daniel Wagner - 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()
