Accepting request 1181395 from home:wagi:branches:benchmark 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 OBS-URL: https://build.opensuse.org/request/show/1181395 OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/libtracefs?expand=0&rev=33
