perf tools: Include errno.h where needed

2017-04-19T16:01:51+00:00

Removing it from util.h, part of an effort to disentangle the includes hell, that makes changes to util.h or something included by it to cause a complete rebuild of the tools.

perf tools: Including missing inttypes.h header

2017-04-19T16:01:46+00:00

Needed to use the PRI[xu](32,64) formatting macros. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-wkbho8kaw24q67dd11q0j39f@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf utils: Check verbose flag properly

2017-02-20T14:35:54+00:00

It now can have negative value to suppress the message entirely. So it needs to check it being positive.

perf tests record: No need to test an array against NULL

2017-02-13T20:22:34+00:00

It will always evaluate to 'true', as clang warns: CC /tmp/build/perf/tests/perf-record.o CC /tmp/build/perf/tests/evsel-roundtrip-name.o tests/perf-record.c:69:24: error: comparison of array 'argv' equal to a null pointer is always false [-Werror,-Wtautological-pointer-compare] if (evlist == NULL || argv == NULL) { ^~~~ ~~~~ 1 error generated.

tools: Introduce str_error_r()

2016-07-12T18:19:47+00:00

The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error formatted in a provided buffer (we have to check if it returned something else and copy that instead), breaks the build on systems not using glibc, like Alpine Linux, where musl libc is used. So, introduce yet another wrapper, str_error_r(), that has the GNU interface, but uses the portable XSI variant of strerror_r(), so that users rest asured that the provided buffer is used and it is what is returned.

perf evsel: Do not use globals in config()

2016-04-12T01:18:20+00:00

Instead receive a callchain_param pointer to configure callchain aspects, not doing so if NULL is passed. This will allow fine grained control over which evsels in an evlist gets callchains enabled.

perf test: No need for setting attr.sample_freq on the RECORD test

2016-01-07T16:20:22+00:00

We're not looking at PERF_RECORD_SAMPLE entries and now by default we use PERF_COUNT_SW_DUMMY, so just remove that setting.

perf test: Use "dummy" events in the PERF_RECORD_ test

perf tests: Pass the subtest index to each test routine

2015-11-19T16:19:15+00:00

Some tests have sub-tests we want to run, so allow passing this. Wang tried to avoid having to touch all tests, but then, having the test.func in an anonymous union makes the build fail on older compilers, like the one in RHEL6, where: test a = { .func = foo, }; fails. To fix it leave the func pointer in the main structure and pass the subtest index to all tests, end result function is the same, but we have just one function pointer, not two, with and without the subtest index as an argument.
