Date: Thu, 24 Aug 2017 18:27:32 +0200
Message-ID: <20170824162737.7813-6-jolsa@kernel.org> (raw)
In-Reply-To: <20170824162737.7813-1-jolsa@kernel.org>

Adding dump_read function to gather all the dump output
of read function. Adding output of enabled and running
times and id if enabled (3 new lines with '...' prefix
below).

  $ perf record -s ...
  $ perf report -D

  958358311769 0x91f8 [0x40]: PERF_RECORD_READ: 3339 3339 cycles:u 0
  ... time enabled : 958358313731
  ... time running : 958358313731
  ... id           : 80
