perf tests: Fix static build test

2019-09-20T17:37:28Z

Disable the potentional shared library features, which breaks static build if they are enabled and detected: jvmti and vdso libraries.

perf tests: Add libperf automated test for 'make -C tools/perf build-test'

2019-09-10T13:33:32Z

Add a libperf build test, that is triggered when one does: $ make -C tools/perf build-test Signed-off-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: Michael Petlan Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lore.kernel.org/lkml/20190901124822.10132-4-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add NO_LIBCAP=1 to the minimal build test

2019-08-14T13:59:59Z

We need to add these so that we test building without all selectable features.

Pull kbuild updates from Michal Marek: - prototypes for x86 asm-exported symbols (Adam Borowski) and a warning about missing CRCs (Nick Piggin) - asm-exports fix for LTO (Nicolas Pitre) - thin archives improvements (Nick Piggin) - linker script fix for CONFIG_LD_DEAD_CODE_DATA_ELIMINATION (Nick Piggin) - genksyms support for __builtin_va_list keyword - misc minor fixes * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: x86/kbuild: enable modversions for symbols exported from asm kbuild: fix scripts/adjust_autoksyms.sh* for the no modules case scripts/kallsyms: remove last remnants of --page-offset option make use of make variable CURDIR instead of calling pwd kbuild: cmd_export_list: tighten the sed script kbuild: minor improvement for thin archives build kbuild: modpost warn if export version crc is missing kbuild: keep data tables through dead code elimination kbuild: improve linker compatibility with lib-ksyms.o build genksyms: Regenerate parser kbuild/genksyms: handle va_list type kbuild: thin archives for multi-y targets kbuild: kallsyms allow 3-pass generation if symbols size has changed

make use of make variable CURDIR instead of calling pwd

2016-12-11T11:12:56Z

make already provides the current working directory in a variable, so make use of it instead of forking a shell. Also replace usage of PWD by CURDIR. PWD is provided by most shells, but not all, so this makes the build system more robust. Signed-off-by: Uwe Kleine-König Signed-off-by: Michal Marek

perf tools: Cleanup build directory before each test

Cleanup the fixdep tool before every test. Signed-off-by: Jiri Olsa Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1480884178-8072-8-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf build: Add clang and llvm compile and linking support

2016-12-05T18:51:43Z

Add necessary c++ flags and link libraries to support builtin clang and LLVM. Add all llvm and clang libraries, so don't need to worry about clang changes its libraries setting. However, linking perf would take much longer than usual.

perf jvmti: Plug compilation into perf build

2016-11-14T15:42:47Z

Compile jvmti agent as part of the perf build. The agent library is called libperf-jvmti.so and is installed in default place together with other files: $ make libperf-jvmti.so BUILD: Doing 'make -j4' parallel build ... CC jvmti/libjvmti.o CC jvmti/jvmti_agent.o LD jvmti/jvmti-in.o LINK libperf-jvmti.so $ make DESTDIR=/tmp/krava/ install-bin ... $ find /tmp/krava/ | grep libperf /tmp/krava/lib64/libperf-jvmti.so /tmp/krava/lib64/libperf-gtk.so Signed-off-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Tested-by: Stephane Eranian Cc: Andi Kleen Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Cc: William Cohen Link: http://lkml.kernel.org/r/1478093749-5602-4-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf build: Add sdt feature detection

2016-07-14T02:09:09Z

This checks whether sys/sdt.h is available or not, which is required for DTRACE_PROBE(). We can disable this feature by passing NO_SDT=1 when building. This flag will be used for SDT test case and further SDT events in perftools.
