* perf test: Add 'perf test BPF'Wang Nan2015-11-061-0/+4
| | | | | | | | | | | | | | | | | | | | This patch adds BPF testcase for testing BPF event filtering. By utilizing the result of 'perf test LLVM', this patch compiles the eBPF sample program then test its ability. The BPF script in 'perf test LLVM' lets only 50% samples generated by epoll_pwait() to be captured. This patch runs that system call for 111 times, so the result should contain 56 samples.

* perf tests: Move x86 tests into arch directoryMatt Fleming2015-10-051-28/+0
| | | | | | | | | | | | | | | | | | | | | 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: Add arch testsMatt Fleming2015-10-051-8/+20
| | | | | | | | | | | | | | | | | | | | | | | 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. The main idea is to encourage developers to add arch tests to build out perf's test coverage, without dumping everything in tools/perf/tests.

* perf tests: Introduce iterator function for testsMatt Fleming2015-09-141-16/+16
| | | | | | | | | | | | | | | | | | | | In preparation for introducing more arrays of tests, e.g. "arch tests" (architecture-specific tests), abstract the code to iterate over the list of tests into a helper function. This way, code that uses a 'struct test' doesn't need to worry about how the tests are grouped together and changes to the list of tests doesn't require changes to the code using it.

* perf tools: Add a test for decoding of new x86 instructionsAdrian Hunter2015-09-041-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new test titled: Test x86 instruction decoder - new instructions The purpose of this test is to check the instruction decoder after new instructions have been added. Initially, MPX instructions are tested which are already supported, but the definitions in x86-opcode-map.txt will be tweaked in a subsequent patch, after which this test can be run to verify those changes. The data for the test comes from assembly language instructions in insn-x86-dat-src.c which is converted into bytes by the scripts gen-insn-x86-dat.sh and gen-insn-x86-dat.awk, and included into the test program insn-x86.c as insn-x86-dat-32.c and insn-x86-dat-64.c. The conversion is not done as part of the perf tools build because the test data must be under (git) change control in order for the test to be repeatably-correct. Also it may require a recent version of binutils.

* perf tests: Add LLVM test for eBPF on-the-fly compilingWang Nan2015-08-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous patches introduce llvm__compile_bpf() to compile source file to eBPF object. This patch adds testcase to test it. It also tests libbpf by opening generated object after applying next patch which introduces HAVE_LIBBPF_SUPPORT option. Since llvm__compile_bpf() prints long messages which users who don't explicitly test llvm doesn't care, this patch set verbose to -1 to suppress all debug, warning and error message, and hint user use 'perf test -v' to see the full output. For the same reason, if clang is not found in PATH and there's no [llvm] section in .perfconfig, skip this test.

* perf tests: Switch from open to openatRiku Voipio2015-05-291-6/+6

Thus new architectures in kernel, such as arm64, don't implement these legacy syscalls.

* perf tools: Check recorded kernel version when finding vmlinuxNamhyung Kim2014-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently vmlinux_path__init() only tries to find vmlinux file from current directory, /boot and some canonical directories with version number of the running kernel. This can be a problem when reporting old data recorded on a kernel version not running currently. We can use --symfs option for this but it's annoying for user to do it always. As we already have the info in the perf.data file, it can be changed to use it for the search automatically.

This is related to x86_64 RF EFLAGS bit being managed in a wrong way.

| | | | | | | | | | | | | | | | | | | | | | | | | As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.
