The following changes since commit 34c4a42791bbc455e65a15d12dcd0b6b3c52ad13: Merge tag 'perf-core-for-mingo-20161205' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-12-06 09:14:56 +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-20161207 for you to fetch changes up to 108a7c103b761309ccbd997002e8428808cf1e04: perf tools: Explicitly document that --children is enabled by default (2016-12-07 12:00:35 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: Improvements: - Improve error message when analyzing file with required events in 'perf sched timehist' (David Ahern) Fixes: - Force fixdep compilation to be done at the start of the build, fixing some build race conditions in high core count machines (Jiri Olsa) - Fix handling a zero sample->tid in 'perf sched timehist', as sometimes that isn't the idle thread (Namhyung Kim) Infrastructure: - Check minimal accepted LLVM version in its feature check, 3.9 at this time (Wang Nan) Documentation: - Explicitly document that --children is enabled by default (Yannick Brosseau) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- David Ahern (1): perf sched timehist: Improve error message when analyzing wrong file Jiri Olsa (3): perf tools: Move PERF-VERSION-FILE target into rules area perf tools: Force fixdep compilation at the start of the build perf tools: Move perf build related variables under non fixdep leg Namhyung Kim (4): perf sched: Cleanup option processing perf callchain: Introduce callchain_cursor__copy() perf sched timehist: Handle zero sample->tid properly perf sched timehist: Cleanup idle_max_cpu handling Wang Nan (1): perf build: Check LLVM version in feature check Yannick Brosseau (1): perf tools: Explicitly document that --children is enabled by default tools/build/feature/Makefile | 8 +++- tools/build/feature/test-llvm-version.cpp | 11 +++++ tools/build/feature/test-llvm.cpp | 5 +++ tools/perf/Documentation/perf-report.txt | 3 +- tools/perf/Documentation/perf-top.txt | 1 + tools/perf/Makefile.config | 8 +++- tools/perf/Makefile.perf | 68 +++++++++++++++++++++---------- tools/perf/builtin-sched.c | 26 ++++++------ tools/perf/util/callchain.c | 27 ++++++++++++ tools/perf/util/callchain.h | 3 ++ 10 files changed, 122 insertions(+), 38 deletions(-) create mode 100644 tools/build/feature/test-llvm-version.cpp # uname -a Linux jouet 4.8.8-300.fc25.x86_64 #1 SMP Tue Nov 15 18:10:06 UTC 2016 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: Parse event definition strings : Ok 6: PERF_RECORD_* events & perf_sample fields : Ok 7: Parse perf pmu format : Ok 8: DSO data read : Ok 9: DSO data cache : Ok 10: DSO data reopen : Ok 11: Roundtrip evsel->name : Ok 12: Parse sched tracepoints fields : Ok 13: syscalls:sys_enter_openat event fields : Ok 14: Setup struct perf_event_attr : Ok 15: Match and link multiple hists : Ok 16: 'import perf' in python : Ok 17: Breakpoint overflow signal handler : Ok 18: Breakpoint overflow sampling : Ok 19: Number of exit events of a simple workload : Ok 20: Software clock events period values : Ok 21: Object code reading : Ok 22: Sample parsing : Ok 23: Use a dummy software event to keep tracking: Ok 24: Parse with no sample_id_all bit set : Ok 25: Filter hist entries : Ok 26: Lookup mmap thread : Ok 27: Share thread mg : Ok 28: Sort output of hist entries : Ok 29: Cumulate child hist entries : Ok 30: Track with sched_switch : Ok 31: Filter fds with revents mask in a fdarray : Ok 32: Add fd to a fdarray, making it autogrow : Ok 33: kmod_path__parse : Ok 34: Thread map : Ok 35: LLVM search and compile : 35.1: Basic BPF llvm compile : Ok 35.2: kbuild searching : Ok 35.3: Compile source for BPF prologue generation: Ok 35.4: Compile source for BPF relocation : Ok 36: Session topology : Ok 37: BPF filter : 37.1: Basic BPF filtering : Ok 37.2: BPF prologue generation : Ok 37.3: BPF relocation checker : Ok 38: Synthesize thread map : Ok 39: Synthesize cpu map : Ok 40: Synthesize stat config : Ok 41: Synthesize stat : Ok 42: Synthesize stat round : Ok 43: Synthesize attr update : Ok 44: Event times : Ok 45: Read backward ring buffer : Ok 46: Print cpu map : Ok 47: Probe SDT events : Ok 48: is_printable_array : Ok 49: Print bitmap : Ok 50: perf hooks : Ok 51: builtin clang support : 51.1: builtin clang compile C source to IR : Ok 51.2: builtin clang compile C source to ELF object: Ok 52: x86 rdpmc : Ok 53: Convert perf time to TSC : Ok 54: DWARF unwind : Ok 55: x86 instruction decoder -
