The following changes since commit 6a6b12e2125591e24891e6860410795ea53aed11: Merge tag 'perf-core-for-mingo-20161114' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-11-15 09:45:04 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-20161123 for you to fetch changes up to a407b0678bc1c39d70af5fdbe6421c164b69a8c0: perf sched timehist: Add -V/--cpu-visual option (2016-11-23 10:44:09 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: New tool: - 'perf sched timehist' provides an analysis of scheduling events. Example usage: perf sched record -- sleep 1 perf sched timehist By default it shows the individual schedule events, including the wait time (time between sched-out and next sched-in events for the task), the task scheduling delay (time between wakeup and actually running) and run time for the task: time cpu task name wait time sch delay run time [tid/pid] (msec) (msec) (msec) -------- ------ ---------------- --------- --------- -------- 1.874569 [0011] gcc[31949] 0.014 0.000 1.148 1.874591 [0010] gcc[31951] 0.000 0.000 0.024 1.874603 [0010] migration/10[59] 3.350 0.004 0.011 1.874604 [0011] 1.148 0.000 0.035 1.874723 [0005] 0.016 0.000 1.383 1.874746 [0005] gcc[31949] 0.153 0.078 0.022 ... Times are in msec.usec. (David Ahern, Namhyung Kim) Improvements: - Make 'perf c2c report' support -f/--force, to allow skipping the ownership check for root users, for instance, just like the other tools (Jiri Olsa) - Allow sorting cachelines by total number of HITMs, in addition to local and remote numbers (Jiri Olsa) Fixes: - Make sure errors aren't suppressed by the TUI reset at the end of a 'perf c2c report' session (Jiri Olsa) Infrastructure: - Initial work on having the annotate code better support multiple architectures, including the ability to cross-annotate, i.e. to annotate perf.data files collected on an ARM system on a x86_64 workstation (Arnaldo Carvalho de Melo, Ravi Bangoria, Kim Phillips) - Use USECS_PER_SEC instead of hard coded number in libtraceevent (Steven Rostedt) - Add retrieval of preempt count and latency flags in libtraceevent (Steven Rostedt) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Arnaldo Carvalho de Melo (3): perf annotate: Start supporting cross arch annotation perf annotate: Allow arches to specify functions to skip perf annotate: Add per arch instructions annotate handlers David Ahern (5): perf sched timehist: Introduce timehist command perf sched timehist: Add summary options perf sched timehist: Add -w/--wakeups option perf sched timehist: Add call graph options perf sched timehist: Add -V/--cpu-visual option Jiri Olsa (6): perf tools: Show event fd in debug output perf c2c report: Setup browser after opening perf.data perf c2c report: Add -f/--force option perf c2c report: Add struct c2c_stats::tot_hitm field perf c2c report: Display total HITMs on default perf c2c: Support cascading options Namhyung Kim (2): perf symbols: Print symbol offsets conditionally perf evsel: Support printing callchains with arrows Steven Rostedt (2): tools lib traceevent: Use USECS_PER_SEC instead of hardcoded number tools lib traceevent: Add retrieval of preempt count and latency flags tools/lib/traceevent/event-parse.c | 41 +- tools/lib/traceevent/event-parse.h | 5 +- tools/perf/Documentation/perf-c2c.txt | 8 + tools/perf/Documentation/perf-sched.txt | 66 +- tools/perf/arch/arm/annotate/instructions.c | 90 +++ tools/perf/arch/x86/annotate/instructions.c | 78 +++ tools/perf/builtin-c2c.c | 80 ++- tools/perf/builtin-sched.c | 914 +++++++++++++++++++++++++++- tools/perf/builtin-top.c | 2 +- tools/perf/ui/browsers/annotate.c | 2 +- tools/perf/ui/gtk/annotate.c | 2 +- tools/perf/util/annotate.c | 251 ++++---- tools/perf/util/annotate.h | 6 +- tools/perf/util/evsel.c | 6 +- tools/perf/util/evsel.h | 1 + tools/perf/util/evsel_fprintf.c | 12 +- tools/perf/util/mem-events.c | 12 +- tools/perf/util/mem-events.h | 1 + tools/perf/util/symbol.h | 3 +- tools/perf/util/symbol_fprintf.c | 11 +- 20 files changed, 1406 insertions(+), 185 deletions(-) create mode 100644 tools/perf/arch/arm/annotate/instructions.c create mode 100644 tools/perf/arch/x86/annotate/instructions.c # uname -a Linux jouet 4.8.6-201.fc24.x86_64 #1 SMP Thu Nov 3 14:38:57 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux # perf test 1: vmlinux symtab matches kallsyms : Ok 2: detect openat syscall event : Ok 3: detect openat syscall event on all cpus : Ok 4: read samples using the mmap interface : Ok 5: parse events tests : Ok 6: Validate PERF_RECORD_* events & perf_sample fields : Ok 7: Test perf pmu format parsing : Ok 8: Test dso data read : Ok 9: Test dso data cache : Ok 10: Test dso data reopen : Ok 11: roundtrip evsel->name check : Ok 12: Check parsing of sched tracepoints fields : Ok 13: Generate and check syscalls:sys_enter_openat event fields: Ok 14: struct perf_event_attr setup : Ok 15: Test matching and linking multiple hists : Ok 16: Try 'import perf' in python, checking link problems : Ok 17: Test breakpoint overflow signal handler : Ok 18: Test breakpoint overflow sampling : Ok 19: Test number of exit event of a simple workload : Ok 20: Test software clock events have valid period values : Ok 21: Test object code reading : Ok 22: Test sample parsing : Ok 23: Test using a dummy software event to keep tracking : Ok 24: Test parsing with no sample_id_all bit set : Ok 25: Test filtering hist entries : Ok 26: Test mmap thread lookup : Ok 27: Test thread mg sharing : Ok 28: Test output sorting of hist entries : Ok 29: Test cumulation of child hist entries : Ok 30: Test tracking with sched_switch : Ok 31: Filter fds with revents mask in a fdarray : Ok 32: Add fd to a fdarray, making it autogrow : Ok 33: Test kmod_path__parse function : Ok 34: Test thread map : Ok 35: Test LLVM searching and compiling : 35.1: Basic BPF llvm compiling test : Ok 35.2: Test kbuild searching : Ok 35.3: Compile source for BPF prologue generation test : Ok 35.4: Compile source for BPF relocation test : Ok 36: Test topology in session : Ok 37: Test BPF filter : 37.1: Test basic BPF filtering : Ok 37.2: Test BPF prologue generation : Ok 37.3: Test BPF relocation checker : Ok 38: Test thread map synthesize : Ok 39: Test cpu map synthesize : Ok 40: Test stat config synthesize : Ok 41: Test stat synthesize : Ok 42: Test stat round synthesize : Ok 43: Test attr update synthesize : Ok 44: Test events times : Ok 45: Test backward reading from ring buffer : Ok 46: Test cpu map print : Ok 47: Test SDT event probing : Ok 48: Test is_printable_array function : Ok 49: Test bitmap print : Ok 50: x86 rdpmc test : Ok 51: Test converting perf time to TSC : Ok 52: Test dwarf unwind : Ok 53: Test x86 instruction decoder -
