X-Git-Tag: v4.9.8~4301^2~115 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ed39bac21c3c2934b18de34df9478ad7b8edf1f;p=platform%2Fkernel%2Flinux-rpi3.git Merge tag 'perf-core-for-mingo' of git://git./linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Show precise number of samples in at the end of a 'record' session, if processing build ids, since we will then traverse the whole perf.data file and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the previous off-base heuristicly counted number of "samples" (Namhyung Kim). - Support to read compressed module from build-id cache (Namhyung Kim) Infrastructure changes: - Cache eh/debug frame offset for dwarf unwind (Namhyung Kim) - Set header version correctly in all cases (Namhyung Kim) - Set attr.task bit for a tracking event, to be consistent (Namhyung Kim) perf tools: Use perf_data_file__fd() consistently perf symbols: Convert lseek + read to pread - Don't rely on malloc working for sz 0, fixing another problem when using uClibc (Vineet Gupta) - Provide stub for missing pthread_attr_setaffinity_np for libcs where this is not available, such as uClibc (Vineet Gupta) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- 1ed39bac21c3c2934b18de34df9478ad7b8edf1f
