X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c3a3800fe46f00ceeeb181cc07cc4fdaed4574f1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Merge tag 'perf-core-for-mingo-4.14-20170728' of git://git./linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes for 4.14 from Arnaldo Carvalho de Melo: New features: - Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data' CTF conversion, allowing CTF trace visualization tools to show callchains and to resolve symbols (Geneviève Bastien) Improvements: - Use group read for event groups in 'perf stat', reducing overhead when groups are defined in the event specification, i.e. when using {} to enclose a list of events, asking them to be read at the same time, e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa) Fixes: - Do not overwrite perf_sample->weight in 'perf annotate' when processing samples, use whatever came from the kernel when perf_event_attr.sample_type has PERF_SAMPLE_WEIGHT set or just handle its default value, 0, when that is not set and "weight" is one of the sort orders chosen (Arnaldo Carvalho de Melo) - 'perf annotate --show-total-period' fixes: - TUI should show period, not nr_samples - Set appropriate column width for period/percent - Fix the column header to show "Period" when when that is what is being asked for (Taeung Song, Arnaldo Carvalho de Melo) - Use default sort if evlist is empty, fixing pipe mode (David Carrillo-Cisneros) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- c3a3800fe46f00ceeeb181cc07cc4fdaed4574f1
