A basic infrastructure for compression support is added into the trace-cmd library. The zlib is used for compression, but more libraries and algorithms can be added. Trace data is commpressed and part of the trace file metadata: - ftrace events format - format of recorded events - information about the mapping of function addresses to the function names - trace_printk() format strings - information of the mapping a PID to a process name - options Note: not all trace-cmd commands are tested with these changes. These are verified to work with compressed trace files: trace-cmd record trace-cmd report trace-cmd dump trace-cmd agent trace-cmd profile trace-cmd split trace-cmd convert Todo list, in order to have complete trace file compression: - Add support for more compression libraries. - Test all trace-cmd commands with trace file v7. v6 changes: - Documentation upadate. - Bug fixes. - Coding style fixes. v5 changes: - Comress the latency trace data. - Add new "trace-cmd convert" subcommand. - Fixed bug with empty CPUs in the trace file. - A lot of minor bug fixes. v4 changes: - Tested and fixed profile and split subcommands with compression files. - Bug fixes. v3 changes: - Compress the trace data. - Added documentation to all compression APIs. - A few minor fixes. v2 changes: - Refactored compression APIs. - Moved the trace buffers description out of the trace options section. - Added compression of "options" section of the trace file. - Updated "trace-cmd list" to show available compression algorithms. - Tested with host-guest tracing. - Merged with the patchset that bumps the trace file version.
