      perf top: Use the TUI interface by default · 8b1bfdbd
      Arnaldo Carvalho de Melo 提交于
      To disable it either:
      
      1. Make sure newt-devel is not installed when building it
      
      2. Use 'perf top --stdio' just like with report
      
      3. Edit your ~/.perfconfig or system wide config and have this there:
      
      [tui]
      
      	top = off
      
      But you shouldn't, since the TUI is so much more powerful, has
      integration with annotation and where lots more interesting features
      will be developed, so if something annoys you (the colors?) just let me
      know and I'll do my best to make it pleasant as a default.

      perf annotate browser: Allow navigation to called functions · 34958544
      Arnaldo Carvalho de Melo 提交于
      I.e. when in the annotate TUI window, if Enter is pressed over an
      assembly line with a 'callq' it will try to open another TUI window with
      that symbol.
      
      This is just a proof of concept and works only on x86_64, more work is
      needed to support kernel modules, userland, other arches, etc, but
      should already be useful as-is.

      perf top: Add callgraph support · 19d4ac3c
      Arnaldo Carvalho de Melo 提交于
      Just like in 'perf report', but live.
      
      Still needs to decay the callchains, but already somewhat useful as-is.

      perf top: Reuse the 'report' hist_entry/hists classes · ab81f3fd
      Arnaldo Carvalho de Melo 提交于
      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)

      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.
