The following changes since commit e3a6a62400520452fe39740dca90a1d0b94b8f92: Merge tag 'perf-core-for-mingo-4.12-20170324' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2017-03-24 19:37:40 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.12-20170327 for you to fetch changes up to 55f77128e7652e537d6c226d5b56821cdb5c22de: perf utils: Readlink /proc/self/exe to find the perf binary (2017-03-27 15:37:54 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: New features: - Handle inline functions in callchains (Jin Yao) - Enable sorting by srcline as key (Milian Wolff) Fixes: - Fix no_size logic in addr_filter__resolve_kernel_syms() in the auxtrace code (Adrian Hunter) - Fix some thread refcount leaks in 'perf trace' (Arnaldo Carvalho de Melo) - Fix divide by zero when calculating percent for an event in a group in the annotate by source line code (Taeung Song) - build-id files now aren't anymore symlinks, their parent directories are, so readlink the later (Taeung Song) - Assorted fixes for null termination problems, mostly related to readlink, detected by valgrind (Tommi Rantala) Infrastructure: - Make vfs_getname probe point logic in 'perf trace' more robust wrt length of pathname (Arnaldo Carvalho de Melo) - Remove unused 'prefix' parameter from builtins main functions (Arnaldo Carvalho de Melo) - Show 'perf list sdt' option in man page (Ravi Bangoria) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Adrian Hunter (1): perf auxtrace: Fix no_size logic in addr_filter__resolve_kernel_syms() Arnaldo Carvalho de Melo (4): perf trace: Check for vfs_getname.pathname length perf trace: Fix up error path indentation perf trace: Fixup thread refcounting perf tools: Remove unused 'prefix' from builtin functions Jin Yao (5): perf report: Refactor common code in srcline.c perf report: Find the inline stack for a given address perf report: Introduce --inline option perf report: Show inline stack for stdio mode perf report: Show inline stack for browser mode Milian Wolff (1): perf report: Enable sorting by srcline as key Ravi Bangoria (1): perf list sdt: Show option in man page Taeung Song (2): perf annotate: Fix a bug following symbolic link of a build-id file perf annotate: Fix a bug of division by zero when calculating percent Tommi Rantala (6): perf buildid: Do not update SDT cache with null filename perf buildid: Do not assume that readlink() returns a null terminated string perf tests: Do not assume that readlink() returns a null terminated string perf utils: use sizeof(buf) -

Where clang is available, it is also used to build perf with/without libelf. 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. # dm 1 alpine:3.4: Ok 2 alpine:3.5: Ok 3 alpine:edge: Ok 4 android-ndk:r12b-arm: Ok 5 archlinux:latest: Ok 6 centos:5: Ok 7 centos:6: Ok 8 centos:7: Ok 9 debian:7: Ok 10 debian:8: Ok 11 debian:9: Ok 12 debian:experimental: Ok 13 debian:experimental-x-arm64: Ok 14 debian:experimental-x-mips: Ok 15 debian:experimental-x-mips64: Ok 16 debian:experimental-x-mipsel: Ok 17 fedora:20: Ok 18 fedora:21: Ok 19 fedora:22: Ok 20 fedora:23: Ok 21 fedora:24: Ok 22 fedora:24-x-ARC-uClibc: Ok 23 fedora:25: Ok 24 fedora:rawhide: Ok 25 mageia:5: Ok 26 opensuse:13.2: Ok 27 opensuse:42.1: Ok 28 opensuse:tumbleweed: Ok 29 ubuntu:12.04.5: Ok 30 ubuntu:14.04.4: Ok 31 ubuntu:14.04.4-x-linaro-arm64: Ok 32 ubuntu:15.10: Ok 33 ubuntu:16.04: Ok 34 ubuntu:16.04-x-arm: Ok 35 ubuntu:16.04-x-arm64: Ok 36 ubuntu:16.04-x-powerpc: Ok 37 ubuntu:16.04-x-powerpc64: Ok 38 ubuntu:16.04-x-s390: Ok 39 ubuntu:16.10: Ok 40 ubuntu:17.04: Ok # # uname -a Linux jouet 4.11.0-rc2+ #5 SMP Mon Mar 20 18:12:29 -03 2017 x86_64 x86_64 x86_64 GNU/Linux # This kernel lacks the fix by peterz for 'perf test tsc' # # perf test 1: vmlinux symtab matches kallsyms : Ok 2: Detect openat syscall event : Ok 3: Detect openat syscall event on all cpus : Ok 4: Read samples using the mmap interface : Ok 5: Parse event definition strings : Ok 6: Simple expression parser : Ok 7: PERF_RECORD_* events & perf_sample fields : Ok 8: Parse perf pmu format : Ok 9: DSO data read : Ok 10: DSO data cache : Ok 11: DSO data reopen : Ok 12: Roundtrip evsel->name : Ok 13: Parse sched tracepoints fields : Ok 14: syscalls:sys_enter_openat event fields : Ok 15: Setup struct perf_event_attr : Ok 16: Match and link multiple hists : Ok 17: 'import perf' in python : Ok 18: Breakpoint overflow signal handler : Ok 19: Breakpoint overflow sampling : Ok 20: Number of exit events of a simple workload : Ok 21: Software clock events period values : Ok 22: Object code reading : Ok 23: Sample parsing : Ok 24: Use a dummy software event to keep tracking: Ok 25: Parse with no sample_id_all bit set : Ok 26: Filter hist entries : Ok 27: Lookup mmap thread : Ok 28: Share thread mg : Ok 29: Sort output of hist entries : Ok 30: Cumulate child hist entries : Ok 31: Track with sched_switch : Ok 32: Filter fds with revents mask in a fdarray : Ok 33: Add fd to a fdarray, making it autogrow : Ok 34: kmod_path__parse : Ok 35: Thread map : Ok 36: LLVM search and compile : 36.1: Basic BPF llvm compile : Ok 36.2: kbuild searching : Ok 36.3: Compile source for BPF prologue generation: Ok 36.4: Compile source for BPF relocation : Ok 37: Session topology : Ok 38: BPF filter : 38.1: Basic BPF filtering : Ok 38.2: BPF pinning : Ok 38.3: BPF prologue generation : Ok 38.4: BPF relocation checker : Ok 39: Synthesize thread map : Ok 40: Remove thread map : Ok 41: Synthesize cpu map : Ok 42: Synthesize stat config : Ok 43: Synthesize stat : Ok 44: Synthesize stat round : Ok 45: Synthesize attr update : Ok 46: Event times : Ok 47: Read backward ring buffer : Ok 48: Print cpu map : Ok 49: Probe SDT events : Ok 50: is_printable_array : Ok 51: Print bitmap : Ok 52: perf hooks : Ok 53: builtin clang support : Skip (not compiled in) 54: unit_number__scnprintf : Ok 55: x86 rdpmc : Ok 56: Convert perf time to TSC : FAILED!
