perf tools: Allow shuffling the build tests

2015-11-05T14:39:54Z

Those tests take a long time and sometimes we stop it, so allow randomly shuffling the tests so that we have a better chance of running more of them in partial 'make build-test' runs. Using it just on the 'build-test' target, i.e.: make -C tools/perf build-test Is equivalent to: make SHUF=1 -C tools/perf -f tests/make Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-ey7461i9q4k8u0987j8guun6@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Make perf depend on libbpf

2015-10-28T15:48:12Z

By adding libbpf into perf's Makefile, this patch enables perf to build libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set. The newly introduced code is similar to how libapi and libtraceevent are wired into Makefile.perf. MANIFEST is also updated for 'make perf-*-src-pkg'. Append make_no_libbpf to tools/perf/tests/make. The 'bpf' feature check is appended into default FEATURE_TESTS and FEATURE_DISPLAY, so perf will check the API version of bpf in /path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except when we are trying to port this code to an old kernel. Error messages are also updated to notify users about the lack of BPF support in 'perf record' if libelf is missing or the BPF API check failed. tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf files when working on perf using tools/perf/tags.

perf tests: Adding build test for having ending double slash

perf tests: Add test for make install with prefix

Lukas Wunner reported issue (and fix[1]) with 'make install prefix=...'. Adding automated test for this, so it wouldn't happen again.

perf tests: Add testing for Makefile.perf

2015-06-22T14:21:57Z

Currently we test only builds through top level Makefile, but seems like there's a bunch of users using Makefile.perf directly. Changing the make suite to be run for Makefile.perf as well. It takes now considerable amount of time, but hopefully we catch more issues. Also fixing the output indentation for make_kernelsrc and make_kernelsrc_tools tests.

perf tools: Add build option NO_AUXTRACE to exclude AUX area tracing

2015-05-05T21:12:53Z

Add build option NO_AUXTRACE to exclude compiling support for AUX area tracing. Support for both recording and processing is excluded and by implication any future additions such as Intel PT and Intel BTS will also not be compiled in with this option.

perf tools: Fix perf-read-vdsox32 not building and lib64 install dir

2015-03-19T16:38:05Z

Commit: c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on") removed the definition of IS_X86_64 but not all places using it, with the consequence that perf-read-vdsox32 would not be built anymore, and the default lib install directory was 'lib' instead of 'lib64'. Also needs to go to v3.19. Signed-off-by: H.J.
