X-Git-Tag: firefly_0821_release~176^2~832^2~50 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3bd7617596df560e2cb22ad97888cb42dae39d02;p=firefly-linux-kernel-4.4.55.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: - Use PERF_RECORD_SWITCH when available in intel-pt, instead of "sched:sched_switch" events, enabling an unprivileged user to trace multi-threaded or multi-process workloads. (Adrian Hunter) - Always use non inlined file name for 'srcfile' sort key. (Andi Kleen) - Quieten failed to read counter message, helps in systems without backend-stalled-cycles. (Andi Kleen) Infrastructure changes: - Add a 'perf test' entry for decoding of new x86 instructions. (Adrian Hunter) - Add new instructions (sha, clflushopt, clwb, pcommit, rdpkru, wrpkru, xsavec, xsaves, xrstors) to the x86 instruction decoder. (Adrian Hunter) - Add a build test to warn when source code drifts happen for the instruction decoder files in the kernel and in tools/perf. (Adrian Hunter) - Copy linux/filter.h to tools/include. (He Kuang) - Support function __get_dynamic_array_len in libtraceevent. (He Kuanguuu) - Tracing path finding/mounting/error reporting refactorings. (Jiri Olsa) - Store CPU socket and core IDs in perf.data. (Kan Liang) - Reorganize add/del probe insertion routines in 'perf probe'.
