perf tests: Aename open.c to openat.c

2015-05-29T15:43:41Z

Since the test being tested is now openat rather than open, rename the files to make it explicit. The patch is separeted from the first to make it simpler to deal with any potential conflicts in the Makefile Signed-off-by: Riku Voipio Reviewed-by: Ingo Molnar Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1429192375-13706-3-git-send-email-riku.voipio@linaro.org [ Fixed it up wrt Build files ] Signed-off-by: Arnaldo Carvalho de Melo

perf tests: Switch from open to openat

2015-05-29T15:43:41Z

Multiple perf tests fail on arm64 due to missing open syscall: 2: detect open syscall event : FAILED! open(2) is a legacy syscall, replaced with openat(2) since 2.6.16. Thus new architectures in kernel, such as arm64, don't implement these legacy syscalls. The patch replaces all sys_enter_open events with sys_enter_openat, renames the related tests and test output to avoid confusion.

perf evlist: Introduce poll method for common code idiom

2014-09-25T19:46:55Z

Since we have access two evlist members in all these poll calls, provide a helper. This will also help to make the patch introducing the pollfd class more clear, as the evlist specific uses will be hiden away perf_evlist__poll().

perf test: Use strerror_r instead of strerror

2014-08-15T16:07:28Z

Use strerror_r instead of strerror in error messages for thread-safety.

perf tools: Move pr_* debug macros into debug object

2014-07-17T15:58:39Z

Moving pr_* debug macros to have it with in same object as debug variables, becase we will change them to use verbose variable in next patch.

perf record: Rename --no-delay to --no-buffering

2014-01-14T20:57:04Z

That is how the option summary describes it and so that we can free --delay to replace --initial-delay and then be consistent with stat's --delay equivalent option.

perf evlist: Auto unmap on destructor

Removing further boilerplate after making sure perf_evlist__munmap can be called multiple times for the same evlist.

perf evlist: Close fds on destructor

2014-01-13T13:06:22Z

Since it is safe to call perf_evlist__close() multiple times, autoclose it and remove the calls to the close from existing tools, reducing the tooling boilerplate.

perf evlist: Move destruction of maps to evlist destructor

2014-01-13T13:06:21Z

Instead of requiring tools to do an extra destructor call just before calling perf_evlist__delete.

perf tools: Rename 'perf_record_opts' to 'record_opts

2013-12-19T17:43:45Z

Reduce typing, functions use class__method convention, so unlikely to clash with other libraries. This actually was discussed in the "Link:" referenced message below.
