perf tests: Show refcounting broken expectations in thread-mg-share test To help understand the failure. [acme@zoo linux]$ perf test -v 30 30: Test thread mg sharing : --- start --- test child forked, pid 12275 FAILED tests/thread-mg-share.c:68 wrong refcnt (4 != 3) test child finished with -1 ---- end ---- Test thread mg sharing: FAILED! [acme@zoo linux]$ This is under investigation, the thread__delete() calls were replaced with thread__put(), and those cause mismatches because now we need to be more judicious with the thread lifetime management. I.e. previously the thread__delete() would drop the map_group refcount, but now since thread__put doesn't call thread__delete() necessarily. because we have other refcount holders, the map_group refcount will not be as we expected when this test was implemented. Will be fixed soon...

perf tests: Add return states enum for tests Test can currently return one of 3 states: ok, fail, skip. The ok and fail states are self-explanatory. The skip state means that some of the conditions for running the test was not met, making it impossible to even run the test. For instance, if the hardware doesn't support the 'precise' level required by a test, it will be skipped.

perf tests: Add arch tests Tests that only make sense for some architectures currently live in the same place as the generic tests. Move out the x86-specific tests into tools/perf/arch/x86/tests and define an 'arch_tests' array, which is the list of tests that only apply to the build architecture.

perf test: Disable breakpoint signal tests for powerpc The following tests are failing on powerpc: # perf test break 18: Breakpoint overflow signal handler : FAILED! 19: Breakpoint overflow sampling : FAILED! The powerpc kenel so far does not have support to even create instruction breakpoints using the perf event interface, so those tests fail early in the config phase. I added a '->is_supported()' callback to test struct to be able to disable specific tests. It seems better than putting ifdefs directly to the test array.

The first testcase checks if builtin clang is able to generate LLVM IR. tests/clang.c is a proxy. Real testcase resides in utils/c++/clang-test.cpp in c++ and exports C interface to perf test subsystem. Test result: $ perf test -v clang 51: builtin clang support : 51.1: Test builtin clang compile C source to IR : --- start --- test child forked, pid 13215 test child finished with 0 ---- end ---- Test builtin clang support subtest 0: Ok Committer note: Make sure you've enabled CLANG and LLVM builtin support by setting the LIBCLANGLLVM variable on the make command line, e.g.: make LIBCLANGLLVM=1 O=/tmp/build/perf -C tools/perf install-bin Otherwise you'll get this when trying to do the 'perf test' call above: # perf test clang 51: builtin clang support : Skip (not compiled in) # Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexei Starovoitov <ast@fb.com> Cc: He Kuang <hekuang@huawei.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Joe Stringer <joe@ovn.org> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/20161126070354.141764-11-wangnan0@huawei.com [ Removed "Test" from descriptions, redundant and already removed from all the other entries ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf test: Add 'struct test *' to the test functions This way we'll be able to pass more test specific parameters without having to change this function signature. Will be used by the upcoming 'shell tests', shell scripts that will call perf tools and check if they work as expected, comparing its effects on the system (think 'perf probe foo') the output produced, etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Thomas Richter <tmricht@linux.vnet.ibm.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-wq250w7j1opbzyiynozuajbl@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf test: Disable breakpoint signal tests for powerpc The following tests are failing on powerpc: # perf test break 18: Breakpoint overflow signal handler : FAILED! 19: Breakpoint overflow sampling : FAILED! The powerpc kenel so far does not have support to even create instruction breakpoints using the perf event interface, so those tests fail early in the config phase. I added a '->is_supported()' callback to test struct to be able to disable specific tests. It seems better than putting ifdefs directly to the test array.

perf tests: Move x86 tests into arch directory Move out the x86-specific tests into tools/perf/arch/x86/tests and define an 'arch_tests' array, which is the list of tests that only apply to the build architecture. We can also now begin to get rid of some of the #ifdef code that is present in the generic perf tests.

perf tests x86: Add dwarf unwind test Adding dwarf unwind test, that setups live machine data over the perf test thread and does the remote unwind. At this moment this test fails due to bug in the max_stack processing in unwind__get_entries function. This is fixed in following patch. Need to use -fno-optimize-sibling-calls for test compilation, otherwise 'krava_*' function calls are optimized into jumps and ommited from the stack unwind. So far it's enabled only for x86.
