    perf bench: Add "all" pseudo subsystem and "all" pseudo suite · 2044279d
    Hitoshi Mitake authored
    This patch adds a new "all" pseudo subsystem and an "all" pseudo
    suite. These are for testing all subsystem and its all suite, or
    all suite of one subsystem.
    
    (This patch also contains a few trivial comment fixes for
    bench/* and output style fixes. I judged that there are no
    necessity to make them into individual patch.)
    
    Example of use:
    
    | % ./perf bench sched all                      # Test all suites of sched subsystem
    | # Running sched/messaging benchmark...
    | # 20 sender and receiver processes per group
    | # 10 groups == 400 processes run
    |
    |      Total time: 0.414 [sec]
    |
    | # Running sched/pipe benchmark...
    | # Extecuted 1000000 pipe operations between two tasks
    |
    |      Total time: 10.999 [sec]
    |
    |       10.999317 usecs/op
    |           90914 ops/sec
    |
    | % ./perf bench all                            # Test all suites of all subsystems
    | # Running sched/messaging benchmark...
    | # 20 sender and receiver processes per group
    | # 10 groups == 400 processes run
    |
    |      Total time: 0.420 [sec]
    |
    | # Running sched/pipe benchmark...
    | # Extecuted 1000000 pipe operations between two tasks
    |
    |      Total time: 11.741 [sec]
    |
    |       11.741346 usecs/op
    |           85169 ops/sec
    |
    | # Running mem/memcpy benchmark...
