perf tools: Add helpers to use capabilities if present Add utilities to help checking capabilities of the running procss. Make perf link with libcap, if it is available. If no libcap-dev[el], fallback to the geteuid() == 0 test used before. Committer notes: $ perf test python 18: 'import perf' in python : FAILED! $ perf test -v python Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc 18: 'import perf' in python : --- start --- test child forked, pid 23288 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /tmp/build/perf/python/perf.so: undefined symbol: cap_get_flag test child finished with -1 ---- end ---- 'import perf' in python: FAILED! $ This happens because differently from the perf binary generated with this patch applied: $ ldd /tmp/build/perf/perf | grep libcap libcap.so.2 => /lib64/libcap.so.2 (0x00007f724a4ef000) $ The python binding isn't linking with libcap: $ ldd /tmp/build/perf/python/perf.so | grep libcap $ So add 'cap' to the 'extra_libraries' variable in tools/perf/util/setup.py, and rebuild: $ perf test python 18: 'import perf' in python : Ok $ If we explicitely disable libcap it also continues to work: $ make NO_LIBCAP=1 -C tools/perf O=/tmp/build/perf install-bin $ ldd /tmp/build/perf/perf | grep libcap $ ldd /tmp/build/perf/python/perf.so | grep libcap $ perf test python 18: 'import perf' in python : Ok $ Signed-off-by: Igor Lubashev <ilubashe@akamai.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexey Budankov <alexey.budankov@linux.intel.com> Cc: James Morris <jmorris@namei.org> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Suzuki Poulouse <suzuki.poulose@arm.com> Cc: linux-arm-kernel@lists.infradead.org [ split from a larger patch ] Link: http://lkml.kernel.org/r/8a1e76cf5c7c9796d0d4d240fbaa85305298aafa.1565188228.git.ilubashe@akamai.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf tools: Add missing object file to the python binding linkage list In ac12f6764c50 ("perf tools: Implement branch_type event parameter") we started using the parse_branch_str() function from one of the files used in the python binding, which caused this entry in 'perf test' to fail: # perf test -v python 16: Try 'import perf' in python, checking link problems : --- start --- test child forked, pid 16667 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /tmp/build/perf/python/perf.so: undefined symbol: parse_branch_str test child finished with -1 ---- end ---- Try 'import perf' in python, checking link problems: FAILED! # I must've commited some mistake when running 'perf test' to send the pull request for the perf-core-for-mingo-20161024 tag, to have let this regression to pass, sigh. Just add tools/perf/util/parse-branch-options.c and switch from using ui__warning(), that is not available in the python binding, use pr_warning() instead, which is good enough for this case.

perf tools: Add missing files to build the python binding Changeset 0f6a3015: "perf tools: Support user regs and stack in sample parsing" uses hweight_long in evsel.c, so we need to drag util/hweight.c to the python binding. Ditto for ee8dd3c: "perf tools: Change strlist to use the new rblist" where we need to add util/rblist.c.
