Subject: [PATCH 3/5] perf tools data: Add perf data to CTF convertion support
Adding 'perf data convert' to convert perf data file into
different format. This patch adds support for CTF format
conversion.
To convert perf.data into CTF run:
$ perf data convert --to-ctf=./ctf-data/
[ perf data convert: Converted 'perf.data' into CTF data './ctf-data/' ]
[ perf data convert: Converted and wrote 11.268 MB (100230 samples) ]
The command will create CTF metadata out of perf.data file
(or one specified via -i option) and then convert all sample
events into single CTF stream.
Each sample_type bit is translated into separated CTF event
field apart from following exceptions:
PERF_SAMPLE_RAW - added in next patch
PERF_SAMPLE_READ - TODO
PERF_SAMPLE_CALLCHAIN - TODO
PERF_SAMPLE_BRANCH_STACK - TODO
PERF_SAMPLE_REGS_USER - TODO
PERF_SAMPLE_STACK_USER - TODO
$ perf --debug=data-convert=2 data convert ...
The converted CTF data could be analyzed by CTF tools, like:
$ babeltrace ./ctf-data/

Data file related processing.
+
+COMMANDS
+--------
+convert::
+ Converts perf data file into another format (only CTF [1] format is support by now).
+ It's possible to set data-convert debug variable to get debug messages from conversion,
+ like:
+ perf --debug data-convert data convert ...
+
+OPTIONS for 'convert'
+---------------------
+--to-ctf::
+ Triggers the CTF conversion, specify the path of CTF data directory.
+
+-i::
+ Specify input perf data file path.
+
+-v::
+--verbose::
+ Be more verbose (show counter open errors, etc).
