2017-09-25perf tools: Get all of tools/{arch,include}/ in the MANIFESTArnaldo Carvalho de Melo
Now that I'm switching the container builds from using a local volume pointing to the kernel repository with the perf sources, instead getting a detached tarball to be able to use a container cluster, some places broke because I forgot to put some of the required files in tools/perf/MANIFEST, namely some bitsperlong.h files. So, to fix it do the same as for tools/build/ and pack the whole tools/arch/ directory.

2016-07-12tools: Introduce str_error_r()Arnaldo Carvalho de Melo
The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error formatted in a provided buffer (we have to check if it returned something else and copy that instead), breaks the build on systems not using glibc, like Alpine Linux, where musl libc is used. So, introduce yet another wrapper, str_error_r(), that has the GNU interface, but uses the portable XSI variant of strerror_r(), so that users rest asured that the provided buffer is used and it is what is returned.

The commit that introduced it should've moved it to the same place, plus the 'tools/' prefix, but instead moved it to a bogus tools/lib/util/ directory, being the only file there. Move it to tools/lib/find_bit.c, picking the name for the file where these routines live since: 8f6f19dd5143 ("lib: move find_last_bit to lib/find_next_bit.c") Next step is to make tools/lib/find_bit.c to differ from lib/find_bit.c just in removing what is not used by tools/.

2015-10-28perf tools: Make perf depend on libbpfWang Nan
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.

This patch copies filter.h from include/linux/kernel.h to tools/include/linux/filter.h to enable other libraries to use macros in it, like libbpf which will be introduced by further patches. Currently, the filter.h copy only contains the useful macros needed by libbpf for not introducing too much dependence. tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'. One change: The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to suit user space code generator.

2015-08-07perf tests: Add LLVM test for eBPF on-the-fly compilingWang Nan
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.

2015-07-09tools: Copy lib/hweight.c from the kernel sourcesArnaldo Carvalho de Melo
Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has no meaning in tools/perf and because we removed the stubs for it, i.e. we removed the tools/include/linux/export.h file. This fixes the build for the detached tarball sources cases and removes one more source of entanglement with the kernel sources.

We were using the include/linux/rbtree.h directly from the kernel, which broke the build as soon as it started using rcupdate.h, to avoid dragging the rcu header files into tools/, for which there is no use so far, grab a copy of rbtree.h.
