2010-04-03perf tools: Move the prototypes in util/string.h to util.hArnaldo Carvalho de Melo1-1/+0
So that we avoid conflict with libc's string.h header.

2009-12-14perf sched: Fix build failure on sparcDavid Miller2-4/+8
Here, tvec->tv_usec is "unsigned int" not "unsigned long". Since the type is different on every platform, it's probably best to just use long printf formats and cast. Signed-off-by: David S.

2009-12-14perf bench: Add "all" pseudo subsystem and "all" pseudo suiteHitoshi Mitake2-3/+4
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... | # Copying 1MB Bytes from 0x7ff33e920010 to 0x7ff3401ae010 ... | | 808.407437 MB/Sec Signed-off-by: Hitoshi Mitake <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Frederic Weisbecker <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Ingo Molnar <[email protected]>

This way we type less characters and it looks more like the kzalloc kernel counterpart.

2009-11-22perf bench: Make the mem/memcpy tests more user-friendlyHitoshi Mitake1-15/+22
mem-memcpy.c uses perf event system calls to obtain CPU clocks. And it suddenly dies with BUG_ON() when it running on Linux doesn't support perf event. Also fail at calloc() can occur easily when too large length is passed. Fail of calloc() causes sudden death with assert(). These behaviours are not friendly. So I fixed the treating of errors.

2009-11-10perf bench: Clean up bench/bench.hIngo Molnar1-9/+7
Clean up initializers in bench.h: - No need to break the line for function prototypes, they are more readable in a single line. (even if checkpatch complains about it - We try to align definitions / structure fields vertically, to make it all a bit more readable.

2009-11-10perf bench: Modify builtin-pipe.c for processing common optionsHitoshi Mitake1-8/+14
This patch modifies builtin-pipe.c for processing common options. The first option added is "--format". Users of perf bench will be able to specify output style by --format. Usage example: % ./perf bench sched pipe # with no style specify (executing 1000000 pipe operations between two tasks) Total time:5.855 sec 5.855061 usecs/op 170792 ops/sec % ./perf bench --format=simple sched pipe # specified simple 5.988 Signed-off-by: Hitoshi Mitake <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]>

2009-11-09perf bench: Fix bench/sched-pipe.c to wait for child processHitoshi Mitake1-3/+7
Ingo reported this small 'perf bench sched pipe' output problem: | $ ./perf bench sched pipe | (executing 1000000 pipe operations between two tasks) | | Total time:4.898 sec | $ 4.898586 usecs/op | 204140 ops/sec | | the shell prompt came back before the usecs/op and ops/sec line | was printed. Process teardown race, lack of wait() or so? This caused by lack of calling waitpid() by parent process, so I added it.
