Pull perf updates from Ingo Molnar: "The main changes in this cycle were: Kernel: - kprobes updates: use better W^X patterns for code modifications, improve optprobes, remove jprobes. (Masami Hiramatsu, Kees Cook) - core fixes: event timekeeping (enabled/running times statistics) fixes, perf_event_read() locking fixes and cleanups, etc. (Peter Zijlstra) - Extend x86 Intel free-running PEBS support and support x86 user-register sampling in perf record and perf script. (Andi Kleen) Tooling: - Completely rework the way inline frames are handled. Instead of querying for the inline nodes on-demand in the individual tools, we now create proper callchain nodes for inlined frames. (Milian Wolff) - 'perf trace' updates (Arnaldo Carvalho de Melo) - Implement a way to print formatted output to per-event files in 'perf script' to facilitate generate flamegraphs, elliminating the need to write scripts to do that separation (yuzhoujian, Arnaldo Carvalho de Melo) - Update vendor events JSON metrics for Intel's Broadwell, Broadwell Server, Haswell, Haswell Server, IvyBridge, IvyTown, JakeTown, Sandy Bridge, Skylake, SkyLake Server - and Goldmont Plus V1 (Andi Kleen, Kan Liang) - Multithread the synthesizing of PERF_RECORD_ events for pre-existing threads in 'perf top', speeding up that phase, greatly improving the user experience in systems such as Intel's Knights Mill (Kan Liang) - Introduce the concept of weak groups in 'perf stat': try to set up a group, but if it's not schedulable fallback to not using a group. That gives us the best of both worlds: groups if they work, but still a usable fallback if they don't. E.g: (Andi Kleen) - perf sched timehist enhancements (David Ahern) - ... various other enhancements, updates, cleanups and fixes" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (139 commits) kprobes: Don't spam the build log with deprecation warnings arm/kprobes: Remove jprobe test case arm/kprobes: Fix kretprobe test to check correct counter perf srcline: Show correct function name for srcline of callchains perf srcline: Fix memory leak in addr2inlines() perf trace beauty kcmp: Beautify arguments perf trace beauty: Implement pid_fd beautifier tools include uapi: Grab a copy of linux/kcmp.h perf callchain: Fix double mapping al->addr for children without self period perf stat: Make --per-thread update shadow stats to show metrics perf stat: Move the shadow stats scale computation in perf_stat__update_shadow_stats perf tools: Add perf_data_file__write function perf tools: Add struct perf_data_file perf tools: Rename struct perf_data_file to perf_data perf script: Print information about per-event-dump files perf trace beauty prctl: Generate 'option' string table from kernel headers tools include uapi: Grab a copy of linux/prctl.h perf script: Allow creating per-event dump files perf evsel: Restore evsel->priv as a tool private area perf script: Use event_format__fprintf() ... |
