Arnaldo The following changes since commit 3f416f22d1e21709a631189ba169f76fd267b374: perf stat: Do not clean event's private stats (2016-01-26 11:15:11 -0300) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo for you to fetch changes up to 5ac76283b32b116c58e362e99542182ddcfc8262: perf cpumap: Auto initialize cpu__max_{node,cpu} (2016-01-26 16:08:36 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: User visible: - Rename the "colors.code" ~/.perfconfig variable to "colors.jump_arrows", as it controls just the that UI element in the annotate browser (Taeung Song) - Avoid trying to read ELF symtabs from device files, noticed while doing memory profiling work (Jiri Olsa) - Improve context detection when offering options in the hists browser, i.e. some options don't make sense when the browser is not working with a perf.data file ('perf top' mode), only in 'perf report' mode, like scripting (Namhyung Kim) Infrastructure: - Elliminate duplication in the hists browser filter functions, getting the common part into a function that receives callbacks for filtering by DSO, thread, etc (Namhyung Kim) - Fix misleadingly indented assignment, found using gcc6 -Wmisleading-indentation (Markus Trippelsdorf) - Handle LLVM relocation oddities in libbpf, introducing a 'perf test' that detects such problems and then fixing the problem, so that the test now passes (Wang Nan) - More improvements to the build infrastructure to allow reusing the feature detection facilities (Wang Nan) - Auto initialize the globals needed by cpu__max_{cpu,node}() routines (Arnaldo Carvalho de Melo) Documentation: - Document the perf sysctls in Documentation/sysctl/kernel.txt (Ben Hutchings) - Document a bunch more ~/.perfconfig knobs (Taeung Song) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Arnaldo Carvalho de Melo (3): perf machine: Introduce machine__find_kernel_symbol_by_name() perf test: Fixup aliases checking in the 'vmlinux matches kallsyms' test perf cpumap: Auto initialize cpu__max_{node,cpu} Ben Hutchings (1): perf tools: Document the perf sysctls Jiri Olsa (2): perf symbols: Do not read symbols/data from device files perf stat: Making several helper functions static Markus Trippelsdorf (1): perf pmu: Fix misleadingly indented assignment (whitespace) Namhyung Kim (9): perf hists: Remove parent filter check in DSO filter function perf hists: Cleanup filtering functions perf sort: Provide a way to find out if per-thread bucketing is in place perf hists browser: Only 'Zoom into thread' only when sort order has 'pid' perf hists browser: Only offer symbol scripting when a symbol is under the cursor perf hists browser: Offer 'Zoom into DSO'/'Map details' only when sort order has 'dso' perf hists browser: Be a bit more strict about presenting CPU socket zoom perf hists browser: Offer non-symbol specific menu options for --sort without 'sym' perf hists browser: Skip scripting when perf.data file not available Taeung Song (6): perf annotate: Rename 'colors.code' to 'colors.jump_arrows' perf config: Document variables for 'colors' section in man page perf config: Document variables for 'tui' and 'gtk' sections in man page perf config: Document 'buildid.dir' variable in man page perf config: Document variables for 'annotate' section in man page perf config: Document 'hist.percentage' variable in man page Wang Nan (4): perf test: Add libbpf relocation checker perf bpf: Check relocation target section tools build: Allow subprojects select all feature checkers perf build: Select all feature checkers for feature-dump Documentation/sysctl/kernel.txt | 13 ++ tools/build/Makefile.feature | 21 ++- tools/lib/bpf/libbpf.c | 34 +++-- tools/perf/Documentation/perf-config.txt | 200 +++++++++++++++++++++++++- tools/perf/Documentation/perfconfig.example | 2 +- tools/perf/Makefile.perf | 11 +- tools/perf/tests/.gitignore | 1 + tools/perf/tests/Build | 9 +- tools/perf/tests/bpf-script-test-relocation.c | 50 +++++++ tools/perf/tests/bpf.c | 26 +++- tools/perf/tests/llvm.c | 17 ++- tools/perf/tests/llvm.h | 5 +- tools/perf/tests/vmlinux-kallsyms.c | 24 +--- tools/perf/ui/browser.c | 4 +- tools/perf/ui/browser.h | 2 +- tools/perf/ui/browsers/annotate.c | 2 +- tools/perf/ui/browsers/hists.c | 38 ++--- tools/perf/util/cpumap.c | 30 ++++ tools/perf/util/cpumap.h | 32 +---- tools/perf/util/dso.c | 5 + tools/perf/util/evsel.c | 15 +- tools/perf/util/hist.c | 92 ++++-------- tools/perf/util/machine.h | 10 ++ tools/perf/util/pmu.c | 2 +- tools/perf/util/sort.c | 3 + tools/perf/util/sort.h | 2 + tools/perf/util/stat.c | 14 +- tools/perf/util/stat.h | 10 -- tools/perf/util/symbol.c | 6 +- tools/perf/util/util.c | 10 ++ tools/perf/util/util.h | 1 + 31 files changed, 507 insertions(+), 184 deletions(-) create mode 100644 tools/perf/tests/bpf-script-test-relocation.c
