The following changes since commit 7dc41b9b99cd0037a418ac47e342d56a438df649: Merge tag 'perf-urgent-for-mingo-5.7-20200403' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent (2020-04-04 10:35:15 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-5.7-20200413 for you to fetch changes up to 80af1ec0f23235271feda1436f1b5c74078a0453: perf script: Add flamegraph.py script (2020-04-13 11:03:08 -0300) ---------------------------------------------------------------- perf/core fixes and improvements: kernel + tools/perf: Alexey Budankov: - Introduce CAP_PERFMON to kernel and user space. perf stat: Jin Yao: - Fix no metric header if --per-socket and --metric-only set. perf python: Arnaldo Carvalho de Melo: - Check if clang supports -fno-semantic-interposition, fixing the python binding when building with clang. perf script: Andreas Gerstmayr: - Add flamegraph.py script tools arch x86: Arnaldo Carvalho de Melo: - Sync the msr-index.h copy with the kernel sources. perf bench: Ian Rogers: - Add event synthesis benchmark.

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. Ubuntu 19.10 is failing when linking against libllvm, which isn't the default, needs to be investigated, haven't tested with CC=gcc, but should be the same problem: + make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang ... /usr/bin/ld: /usr/lib/llvm-9/lib/libclangAnalysis.a(ExprMutationAnalyzer.cpp.o): in function `clang::ast_matchers::internal::matcher_ignoringImpCasts0Matcher::matches(clang::Expr const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const': (.text._ZNK5clang12ast_matchers8internal32matcher_ignoringImpCasts0Matcher7matchesERKNS_4ExprEPNS1_14ASTMatchFinderEPNS1_21BoundNodesTreeBuilderE[_ZNK5clang12ast_matchers8internal32matcher_ignoringImpCasts0Matcher7matchesERKNS_4ExprEPNS1_14ASTMatchFinderEPNS1_21BoundNodesTreeBuilderE]+0x43): undefined reference to `clang::ast_matchers::internal::DynTypedMatcher::matches(clang::ast_type_traits::DynTypedNode const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const' /usr/bin/ld: /usr/lib/llvm-9/lib/libclangAnalysis.a(ExprMutationAnalyzer.cpp.o): in function `clang::ast_matchers::internal::matcher_hasLoopVariable0Matcher::matches(clang::CXXForRangeStmt const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const': (.text._ZNK5clang12ast_matchers8internal31matcher_hasLoopVariable0Matcher7matchesERKNS_15CXXForRangeStmtEPNS1_14ASTMatchFinderEPNS1_21BoundNodesTreeBuilderE[_ZNK5clang12ast_matchers8internal31matcher_hasLoopVariable0Matcher7matchesERKNS_15CXXForRangeStmtEPNS1_14ASTMatchFinderEPNS1_21BoundNodesTreeBuilderE]+0x48): undefined reference to `clang::ast_matchers::internal::DynTypedMatcher::matches(clang::ast_type_traits::DynTypedNode const&, clang::ast_matchers::internal::ASTMatchFinder*, clang::ast_matchers::internal::BoundNodesTreeBuilder*) const' ...
