libperf: Change tests to single static and shared binaries Make tests to be two binaries 'tests_static' and 'tests_shared', so the maintenance is easier. Adding tests under libperf build system, so we define all the flags just once. Adding make-tests tule to just compile tests without running them.

libperf: Fix perf_cpu_map__for_each_cpu macro Tzvetomir Stoyanov reported an issue with using macro perf_cpu_map__for_each_cpu using private perf_cpu object. The issue is caused by recent change that wrapped cpu in struct perf_cpu to distinguish it from cpu indexes. We need to make struct perf_cpu public. Add a simple test for using the perf_cpu_map__for_each_cpu macro.

libperf tests: Fix typo in perf_evlist__open() failure error messages This patch corrects typos in error messages. I should be "evlist", not "evsel" as the function that fails is perf_evlist__open().

libperf: Add a test case for read formats It checks a various combination of the read format settings and verify it return the value in a proper position. The test uses task-clock software events to guarantee it's always active and sets enabled/running time.

libperf: Add API for allocating new thread map array The existing API perf_thread_map__new_dummy() allocates new thread map for one thread. I couldn't find a way to reallocate the map with more threads, or to allocate a new map for more than one thread. Having multiple threads in a thread map is essential for some use cases. That's why a new API is proposed, which allocates a new thread map for given number of threads: perf_thread_map__new_array() Signed-off-by: Tzvetomir Stoyanov (VMware) <tz.stoyanov@gmail.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Ian Rogers <irogers@google.com> Link: https://lore.kernel.org/linux-perf-users/20220221102628.43904-1-tz.stoyanov@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> | 4 年前 | |
