perf stat has a --delay option to delay measuring the workload. This is useful to skip measuring the startup phase of the program, which is often very different from the main workload. The same is useful for perf record when sampling. --no-delay was already taken, so add a --initial-delay to perf record too. -D was already taken for record, so there is only a long option. v2: Don't disable group members (Namhyung Kim) v3: port to latest perf/core rename to --initial-delay to avoid conflict with --no-delay Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1389476307-2124-1-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Test one of the main kernel Makefile targets to generate a perf sources tarball suitable for build outside the full kernel sources. This is to test that the tools/perf/MANIFEST file lists all the files needed to be in such tarball, which sometimes gets broken when we move files around, like when we made some files that were in tools/perf/ available to other tools/ codebases by moving it to tools/include/, etc. Now everytime we use 'make -C tools/perf -f tests/make' this test will be performed, helping detect such problems earlier in the devel cycle.

2014-01-13perf evlist: Send the errno in the signal when workload failsArnaldo Carvalho de Melo3-11/+60
When a tool uses perf_evlist__start_workload and the supplied workload fails (e.g.: its binary wasn't found), perror was being used to print the error reason. This is undesirable, as the caller may be a GUI, when it wants to have total control of the error reporting process. So move to using sigaction(SA_SIGINFO) + siginfo_t->sa_value->sival_int to communicate to the caller the errno and let it print it using the UI of its choosing.
