Hi,
This is trivial patch.
But, We need readbility about output of the "#>cyclictest --help" command.
Thks,
GeunSik Lim.
== CUT HERE ==
Subject: [PATCH]cyclictest: Arrange alphabetically for readability of "cyclictest --help".
When we use "#> cyclictest --help" command, we are confusing because of
random order of many options. Arrange alphabetically.
After Patch)
[root@fedora11 rt-tests]# ./cyclictest --help
cyclictest V 0.46
Usage:
cyclictest <options>
-a [NUM] --affinity run thread #N on processor #N, if possible
with NUM pin all threads to the processor NUM
-b USEC --breaktrace=USEC send break trace command when latency > USEC
-B --preemptirqs both preempt and irqsoff tracing (used with -b)
-c CLOCK --clock=CLOCK select clock
0 = CLOCK_MONOTONIC (default)
1 = CLOCK_REALTIME
-C --context context switch tracing (used with -b)
-d DIST --distance=DIST distance of thread intervals in us default=500
-D --duration=t specify a length for the test run
default is in seconds, but 'm', 'h', or 'd' maybe added
to modify value to minutes, hours or days
-E --event event tracing (used with -b)
-f --ftrace function trace (when -b is active)
-h --histogram=US dump a latency histogram to stdout after the run
(with same priority about many threads)
US is the max time to be be tracked in microseconds
-i INTV --interval=INTV base interval of thread in us default=1000
-I --irqsoff Irqsoff tracing (used with -b)
-l LOOPS --loops=LOOPS number of loops: default=0(endless)
-m --mlockall lock current and future memory allocations
-n --nanosleep use clock_nanosleep
-N --nsecs print results in ns instead of ms (default ms)
-o RED --oscope=RED oscilloscope mode, reduce verbose output by RED
-O TOPT --traceopt=TOPT trace option
-p PRIO --prio=PRIO priority of highest prio thread
-P --preemptoff Preempt off tracing (used with -b)
-q --quiet print only a summary on exit
-r --relative use relative timer instead of absolute
-s --system use sys_nanosleep and sys_setitimer
-t --threads one thread per available processor
-t [NUM] --threads=NUM number of threads:
without NUM, threads = max_cpus
without -t default = 1
-T TRACE --tracer=TRACER set tracing function
configured tracers: unavailable (debugfs not mounted)
-v --verbose output values on stdout for statistics
format: n:c:v n=tasknum c=count v=value in us
-w --wakeup task wakeup tracing (used with -b)
-W --wakeuprt rt task wakeup tracing (used with -b)
-y POLI --policy=POLI policy of realtime thread (1:FIFO, 2:RR)
format: --policy=1(default) or --policy=2
