X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5f1230c9b80b89f404938ff88dfa64a963f74f2c;p=linux-beck.git Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Introduce 'srcfile' sort key: (Andi Kleen) # perf record -F 10000 usleep 1 # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile # Overhead Source File 26.49% copy_page_64.S 5.49% signal.c 0.51% msr.h # It can be combined with other fields, for instance, experiment with '-s srcfile,symbol'. There are some oddities in some distros and with some specific DSOs, being investigated, so your mileage may vary. - Update the column width for the "srcline" sort key (Arnaldo Carvalho de Melo) - Support per-event 'freq' term: (Namhyung Kim) $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1 $ perf evlist -F cpu/instructions,freq=1234/: sample_freq=1234 cycles: sample_period=1000 $ Infrastructure changes: - Move perf_counts struct and functions into separate object (Jiri Olsa) - Unset perf_event_attr::freq when period term is set (Jiri Olsa) - Move callchain option parsing code to util.c (Kan Liang) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- 5f1230c9b80b89f404938ff88dfa64a963f74f2c
