[PATCH 0/3] perf bench: Make output more better

[Hitoshi Mitake]

Hi,

This patch series makes output of perf bench more better.
Current style, keeping user wait and print everything
suddenly after finish, is not good.
And current formatting for values are too ugly.

Example (case of messaging):
| % perf bench sched messaging
| # Running sched/messaging benchmark...
| # 20 sender and receiver processes per group
| # 10 groups == 400 processes run
|
|      Total time:1.490 [sec]

Hitoshi Mitake (3):
  perf bench: Fix builtin-bench.c for more friendly output
  perf bench: Fix sched-pipe.c for more confortable output
  perf bench: Fix sched-message.c for more confortable output

[PATCH 1/3] perf bench: Fix builtin-bench.c for more friendly output

[Hitoshi Mitake]

This patch makes output of perf bench more friendly.
Current style of putput, keeping user wait
and print everything suddenly after finish,
will confuse users. So I fixed it.

Example of use(case of messaging):
| % perf bench sched messaging
| # Running sched/messaging benchmark...  <- printed right after invocation
| # 20 sender and receiver processes per group
| # 10 groups == 400 processes run

|      Total time:1.476 [sec]

[PATCH 2/3] perf bench: Fix sched-pipe.c for more confortable output

[Hitoshi Mitake]

This patch fixes sched-pipe.c for more confortable output.
Change points are comment style description and
formatting numerical values and its units.

Example of use:
| % ./perf bench sched pipe
| # Running sched/pipe benchmark...
| # Extecuted 1000000 pipe operations between two tasks
|
|      Total time:5.822 [sec]
|
|        5.822553 usecs/op
|          171745 ops/sec
