Now that we can process branch data in annotate it makes sense to support enabling branch recording from top too. Most of the code needed for this is already in shared code with report. But we need to add: - The option parsing code (using shared code from the previous patch) - Document the options - Set up the IPC/cycles accounting state in the top session - Call the accounting code in the hist iter callback Signed-off-by: NAndi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1437233094-12844-8-git-send-email-andi@firstfloor.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

For example, in an application with an expensive function implemented with deeply nested recursive calls, the default call-graph presentation is dominated by the different callchains within that function. By ignoring these callees, we can collect the callchains leading into the function and compactly identify what to blame for expensive calls. For example, in this report the callers of garbage_collect() are scattered across the tree: $ perf report -d ruby 2>- | grep -m10 ^[^#]*[a-z] 22.03% ruby [.] gc_mark --- gc_mark |--59.40%-- mark_keyvalue | st_foreach | gc_mark_children | |--99.75%-- rb_gc_mark | | rb_vm_mark | | gc_mark_children | | gc_marks | | |--99.00%-- garbage_collect If we ignore the callees of garbage_collect(), its callers are coalesced: $ perf report --ignore-callees garbage_collect -d ruby 2>- | grep -m10 ^[^#]*[a-z] 72.92% ruby [.] garbage_collect --- garbage_collect vm_xmalloc |--47.08%-- ruby_xmalloc | st_insert2 | rb_hash_aset | |--98.45%-- features_index_add | | rb_provide_feature | | rb_require_safe | | vm_call_method Signed-off-by: NGreg Price <price@mit.edu> Tested-by: NJiri Olsa <jolsa@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20130623031720.GW22203@biohazard-cafe.mit.edu Link: http://lkml.kernel.org/r/20130708115746.GO22203@biohazard-cafe.mit.edu Cc: Fengguang Wu <fengguang.wu@intel.com> [ remove spaces at beginning of line, reported by Fengguang Wu ] Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

Using struct perf_record_opts to specify how to configure the evsel perf_event_attrs. This gets top closer to record in the way it sets up evsels, with the aim of sharing more and more to the point that both will be a single utility. In this direction top now uses the same callchain option parsing as record and that brings DWARF callchains to top, something that was already available for record.

This actually fixes several problems we had in the old 'perf top': 1. Unresolved symbols not show, limitation that came from the old "KernelTop" codebase, to solve it we would need to do changes that would make sym_entry have most of the hist_entry fields. 2. It was using the number of samples, not the sum of sample->period. And brings the --sort code that allows us to have all the views in 'perf report', for instance: [root@emilia ~]# perf top --sort dso PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs) ------------------------------------------------------------------------------ 31.59% libcrypto.so.1.0.0 21.55% [kernel] 18.57% libpython2.6.so.1.0 7.04% libc-2.12.so 6.99% _backend_agg.so 4.72% sshd 1.48% multiarray.so 1.39% libfreetype.so.6.3.22 1.37% perf 0.71% libgobject-2.0.so.0.2200.5 0.53% [tg3] 0.48% libglib-2.0.so.0.2200.5 0.44% libstdc++.so.6.0.13 0.40% libcairo.so.2.10800.8 0.38% libm-2.12.so 0.34% umath.so 0.30% libgdk-x11-2.0.so.0.1800.9 0.22% libpthread-2.12.so 0.20% libgtk-x11-2.0.so.0.1800.9 0.20% librt-2.12.so 0.15% _path.so 0.13% libpango-1.0.so.0.2800.1 0.11% libatlas.so.3.0 0.09% ft2font.so 0.09% libpangoft2-1.0.so.0.2800.1 0.08% libX11.so.6.3.0 0.07% [vdso] 0.06% cyclictest ^C All the filter lists can be used as well: --dsos, --comms, --symbols, etc. The 'perf report' TUI is also reused, being possible to apply all the zoom operations, do annotation, etc. This change will allow multiple simplifications in the symbol system as well, that will be detailed in upcoming changesets.

This patch adds a -C option to stat, record, top to designate a list of CPUs to monitor. CPUs can be specified as a comma-separated list or ranges, no space allowed. Examples: $ perf record -a -C0-1,4-7 sleep 1 $ perf top -C0-4 $ perf stat -a -C1,2,3,4 sleep 1 With perf record in per-thread mode with inherit mode on, samples are collected only when the thread runs on the designated CPUs. The -C option does not turn on system-wide mode automatically. Cc: David S.

By relying on logic in dso__load_kernel_sym(), we can automatically load vmlinux. The only thing which needs to be adjusted, is how --sym-annotate option is handled - now we can't rely on vmlinux been loaded until full successful pass of dso__load_vmlinux(), but that's not the case if we'll do sym_filter_entry setup in symbol_filter(). So move this step right after event__process_sample() where we know the whole dso__load_kernel_sym() pass is done. By the way, though conceptually similar `perf top` still can't annotate userspace - see next patches with fixes.

Several people have suggested that 'perf' has become a full-fledged tool that should be moved out of Documentation/. Move it to the (new) tools/ directory.

Import Git's nice .txt => {man/html/pdf} generation machinery. Fix various errors in the Documentation/perf*.txt description as well. Also fix a bug in builtin-help: we'd map 'perf help top' to 'perftop' if only the 'perf' binary is in the default PATH - confusing the manpage logic. I dont fully understand why Git did it this way - but i suppose it's a migration artifact from their migration from standalone git-xyz commands to 'git xyz' commands. The perf tools were always using the modern form so it's not an issue there.

Add Documentation/perf-stat.txt and Documentation/perf-top.txt. The template that was used for it: Documentation/git-add.txt from Git.
