LGPL-2.1-only
* Sat Jul 27 2024 Jan Engelhardt <jengelh@inai.de>
- 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 <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.

- Add missing headers to syscall() and SYS_* defines
- Add dependency fixes to meson build

the tracefs file system if it was not already mounted.
Same for mounting debugfs with tracefs_debug_dir().

cached directory still exists and is mounted.

lists must be freed with tracefs_list_free(), and now it is mandatory, as
metadata is used to store the size, and normal freeing of the list will
cause memory issues.
