      perf tests: Pass the subtest index to each test routine · 721a1f53
      Arnaldo Carvalho de Melo 提交于
      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.

      perf tools: Add a test for decoding of new x86 instructions · 98e4619f
      Adrian Hunter 提交于
      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 compiling · 9bc898c7
      Wang Nan 提交于
      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.

      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...

        #define kmod_path__parse_ext(__m, __p)  __kmod_path__parse(__m, __p, false, true)
      
      parse kernel module @path and updates @m argument like:
      
        @comp - true if @path contains supported compression suffix,
                false otherwise
        @kmod - true if @path contains '.ko' suffix in right position,
                false otherwise
        @name - if (@alloc_name && @kmod) is true, it contains strdup-ed base name
                of the kernel module without suffixes, otherwise strudup-ed
                base name of @path
        @ext  - if (@alloc_ext && @comp) is true, it contains strdup-ed string
                the compression suffix
      
      It returns 0 if there's no strdup error, -ENOMEM otherwise.

       libapi_dirs:
      	$(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/
      
      in Makefiles, as it will not work in some systems, as in ubuntu13.10.
      
      v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa)
      
      v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to
          be checked if it is really needed there, but has no place in the
          fdarray class (Fix from Jiri Olsa)
      
      v5: Remove evlist details from fdarray grow/filter tests. Improve it a
          bit doing more tests about expected internal state.

      That will use a synthetic evlist with just what is touched by this new
      method to check that it works as expected.
