Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "The main kernel side changes were: - uprobes enhancements (Masami Hiramatsu) - Uncore group events enhancements (David Carrillo-Cisneros) - x86 Intel: Add support for Skylake server uncore PMUs (Kan Liang) - x86 Intel: LBR cleanups and enhancements, for better branch annotation tracking (Peter Zijlstra) - x86 Intel: Add support for PTWRITE and power event tracing (Alexander Shishkin) - ... various fixes, cleanups and smaller enhancements. Lots of tooling changes - a couple of highlights: - Support event group view with hierarchy mode in 'perf top' and 'perf report' (Namhyung Kim) e.g.: $ perf record -e '{cycles,instructions}' make $ perf report --hierarchy --stdio ... # Overhead Command / Shared Object / Symbol # ...................... .................................. ... 25.74% 27.18%sh 19.96% 24.14%libc-2.24.so 9.55% 14.64%[.] __strcmp_sse2 1.54% 0.00%[.] __tfind 1.07% 1.13%[.] _int_malloc 0.95% 0.00%[.] __strchr_sse2 0.89% 1.39%[.] __tsearch 0.76% 0.00%[.] strlen - Add branch stack / basic block info to 'perf annotate --stdio', where for each branch, we add an asm comment after the instruction with information on how often it was taken and predicted. See example with color output at: http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png (Peter Zijlstra) - Add support for using symbols in address filters with Intel PT and ARM CoreSight (hardware assisted tracing facilities) (Adrian Hunter, Mathieu Poirier) - Add support for interacting with Coresight PMU ETMs/PTMs, that are IP blocks to perform hardware assisted tracing on a ARM CPU core (Mathieu Poirier) - Support generating cross arch probes, i.e. if you specify a vmlinux file for different arch than the one in the host machine, $ perf probe --definition function_name args will generate the probe definition string needed to append to the target machine /sys/kernel/debug/tracing/kprobes_events file, using scripting (Masami Hiramatsu). - Allow configuring the default 'perf report -s' sort order in ~/.perfconfig, for instance, "sym,dso" may be more fitting for kernel developers. (Arnaldo Carvalho de Melo) - ... plus lots of other changes, refactorings, features and fixes" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (149 commits) perf tests: Add dwarf unwind test for powerpc perf probe: Match linkage name with mangled name perf probe: Fix to cut off incompatible chars from group name perf probe: Skip if the function address is 0 perf probe: Ignore the error of finding inline instance perf intel-pt: Fix decoding when there are address filters perf intel-pt: Enable decoder to handle TIP.PGD with missing IP perf intel-pt: Read address filter from AUXTRACE_INFO event perf intel-pt: Record address filter in AUXTRACE_INFO event perf intel-pt: Add a helper function for processing AUXTRACE_INFO perf intel-pt: Fix missing error codes processing auxtrace_info perf intel-pt: Add support for recording the max non-turbo ratio perf intel-pt: Fix snapshot overlap detection decoder errors perf probe: Increase debug level of SDT debug messages perf record: Add support for using symbols in address filters perf symbols: Add dso__last_symbol() perf record: Fix error paths perf record: Rename label 'out_symbol_exit' perf script: Fix vanished idle symbols perf evsel: Add support for address filters ...
