Show all headers | View raw

From: Wang Nan <wangnan0@huawei.com>

After this patch, 'perf data convert' convert comm events to output CTF
stream.

Result:

  # perf record -a sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.378 MB perf.data (73 samples)  ]

  # perf data convert --to-ctf ./out.ctf
  [ perf data convert: Converted 'perf.data' into CTF data './out.ctf' ]
  [ perf data convert: Converted and wrote 0.003 MB (73 samples) ]

  # babeltrace --clock-seconds ./out.ctf/
