The following changes since commit 770e96125515daf1c7bc179323f2e0d488dfe6ac: Merge tag 'perf-core-for-mingo-4.14-20170901' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent (2017-09-05 07:14:28 +0200) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-urgent-for-mingo-4.14-20170912 for you to fetch changes up to dfc9eec7716cc0a9f7eb743c703d74cd2d6085a0: perf stat: Wait for the correct child (2017-09-12 12:49:13 -0300) ---------------------------------------------------------------- perf/urgent fixes: - Fix TUI progress bar when delta from new total from that of the previous update is greater than the progress "step" (screen width progress bar block)) (Jiri Olsa) - Make tools/lib/api make DEBUG=1 build use -D_FORTIFY_SOURCE=2 not to cripple debuginfo, just like tools/perf/ does (Jiri Olsa) - Avoid leaking the 'perf.data' file to workloads started from the 'perf record' command line by using the O_CLOEXEC open flag (Jiri Olsa) - Fix building when libunwind's 'unwind.h' file is present in the include path, clashing with tools/perf/util/unwind.h (Milian Wolff) - Check per .perfconfig section entry flag, not just per section (Taeung Song) - Support running perf binaries with a dash in their name, needed to run perf as an AppImage (Milian Wolff) - Wait for the right child by using waitpid() when running workloads from 'perf stat', also to fix using perf as an AppImage (Milian Wolff) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Arnaldo Carvalho de Melo (1): tools include linux: Guard against redefinition of some macros Jiri Olsa (4): tools lib api: Fix make DEBUG=1 build perf tools: Open perf.data with O_CLOEXEC flag perf ui progress: Make sure we always define step value perf ui progress: Fix progress update Milian Wolff (3): perf tests: Fix compile when libunwind's unwind.h is available perf tools: Support running perf binaries with a dash in their name perf stat: Wait for the correct child Taeung Song (1): perf config: Check not only section->from_system_config but also item's tools/include/linux/compiler-gcc.h | 9 ++++++--- tools/lib/api/Makefile | 8 +++++++- tools/perf/builtin-config.c | 2 +- tools/perf/builtin-stat.c | 2 +- tools/perf/perf.c | 14 ++++++++++---- tools/perf/tests/dwarf-unwind.c | 2 +- tools/perf/ui/progress.c | 9 +++++++-- tools/perf/util/data.c | 13 ++++++++++++- 8 files changed, 45 insertions(+), 14 deletions(-) Test results: The first ones are container (docker) based builds of tools/perf with and without libelf support, objtool where it is supported and samples/bpf/, ditto. 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. The 'perf test' also runs shell scripts exercising the tools, checking if they affect the system in certain ways, like setting up kprobes and uprobes, request callchains for well known programs and check that they are the expected ones, see if 'perf trace' beautifies system call arguments correctly, etc. Additionally, a new set of tests, script based, runs the tools in a live system, setting probes in place that then gets used by 'perf trace', with its output compared against expected results. 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:3.6: Ok 4 alpine:edge: Ok 5 android-ndk:r12b-arm: Ok 6 android-ndk:r15c-arm: Ok 7 archlinux:latest: Ok 8 centos:5: Ok 9 centos:6: Ok 10 centos:7: Ok 11 debian:7: Ok 12 debian:8: Ok 13 debian:9: Ok 14 debian:experimental: Ok 15 debian:experimental-x-arm64: Ok 16 debian:experimental-x-mips: Ok 17 debian:experimental-x-mips64: Ok 18 debian:experimental-x-mipsel: Ok 19 fedora:20: Ok 20 fedora:21: Ok 21 fedora:22: Ok 22 fedora:23: Ok 23 fedora:24: Ok 24 fedora:24-x-ARC-uClibc: Ok 25 fedora:25: Ok 26 fedora:26: Ok 27 fedora:rawhide: Ok 28 mageia:5: Ok 29 opensuse:13.2: Ok 30 opensuse:42.1: Ok 31 opensuse:42.2: Ok 32 opensuse:42.3: Ok 33 opensuse:tumbleweed: Ok 34 oraclelinux:6: Ok 35 oraclelinux:7: Ok 36 ubuntu:12.04.5: Ok 37 ubuntu:14.04.4: Ok 38 ubuntu:14.04.4-x-linaro-arm64: Ok 39 ubuntu:15.10: Ok 40 ubuntu:16.04: Ok 41 ubuntu:16.04-x-arm: Ok 42 ubuntu:16.04-x-arm64: Ok 43 ubuntu:16.04-x-powerpc: Ok 44 ubuntu:16.04-x-powerpc64: Ok 45 ubuntu:16.04-x-powerpc64el: Ok 46 ubuntu:16.04-x-s390: Ok 47 ubuntu:16.10: Ok 48 ubuntu:17.04: Ok 49 ubuntu:17.10: Ok # # uname -a Linux jouet 4.13.0-rc7+ #3 SMP Sat Sep 2 09:04:44 -03 2017 x86_64 x86_64 x86_64 GNU/Linux # 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: Test data source output : Ok 6: Parse event definition strings : Ok 7: Simple expression parser : Ok 8: PERF_RECORD_* events & perf_sample fields : Ok 9: Parse perf pmu format : Ok 10: DSO data read : Ok 11: DSO data cache : Ok 12: DSO data reopen : Ok 13: Roundtrip evsel->name : Ok 14: Parse sched tracepoints fields : Ok 15: syscalls:sys_enter_openat event fields : Ok 16: Setup struct perf_event_attr : Ok 17: Match and link multiple hists : Ok 18: 'import perf' in python : Ok 19: Breakpoint overflow signal handler : Ok 20: Breakpoint overflow sampling : Ok 21: Number of exit events of a simple workload : Ok 22: Software clock events period values : Ok 23: Object code reading : Ok 24: Sample parsing : Ok 25: Use a dummy software event to keep tracking : Ok 26: Parse with no sample_id_all bit set : Ok 27: Filter hist entries : Ok 28: Lookup mmap thread : Ok 29: Share thread mg : Ok 30: Sort output of hist entries : Ok 31: Cumulate child hist entries : Ok 32: Track with sched_switch : Ok 33: Filter fds with revents mask in a fdarray : Ok 34: Add fd to a fdarray, making it autogrow : Ok 35: kmod_path__parse : Ok 36: Thread map : Ok 37: LLVM search and compile : 37.1: Basic BPF llvm compile : Ok 37.2: kbuild searching : Ok 37.3: Compile source for BPF prologue generation : Ok 37.4: Compile source for BPF relocation : Ok 38: Session topology : Ok 39: BPF filter : 39.1: Basic BPF filtering : Ok 39.2: BPF pinning : Ok 39.3: BPF prologue generation : Ok 39.4: BPF relocation checker : Ok 40: Synthesize thread map : Ok 41: Remove thread map : Ok 42: Synthesize cpu map : Ok 43: Synthesize stat config : Ok 44: Synthesize stat : Ok 45: Synthesize stat round : Ok 46: Synthesize attr update : Ok 47: Event times : Ok 48: Read backward ring buffer : Ok 49: Print cpu map : Ok 50: Probe SDT events : Ok 51: is_printable_array : Ok 52: Print bitmap : Ok 53: perf hooks : Ok 54: builtin clang support : Skip (not compiled in) 55: unit_number__scnprintf : Ok 56: x86 rdpmc : Ok 57: Convert perf time to TSC : Ok 58: DWARF unwind : Ok 59: x86 instruction decoder -
