      perf symbols: Factor DSO symtab types to generic binary types · 44f24cb3
      Jiri Olsa 提交于
      Adding interface to access DSOs so it could be used
      from another place.
      
      New DSO binary type is added - making current SYMTAB__*
      types more general:
         DSO_BINARY_TYPE__* = SYMTAB__*
      
      Following function is added to return path based on the specified
      binary type:
         dso__binary_type_file

      perf annotate: Add missing newline on error message · ff2a6617
      Namhyung Kim 提交于
      If perf.data couldn't find vmlinux image for the given build-id,
      it would print error message. However it lacked a newline at the
      end, so the output looked like below:
      
       $ perf annotate --stdio
       No vmlinux file with build id 63b554b2e90f14a4bced200008865e757d3e8b36
       was found in the path.
      
       Please use:
      
         perf buildid-cache -av vmlinux
      
       or:
      
         --vmlinux vmlinux Percent |   Source code & Disassembly of a.out

           0.00 :        400521:       retq
      
      Fix it by adding a newline at the end of the message. It doesn't affect
      the tui output AFAICS. New output will look like this:

      AFAICS the bug is simply that sym->end points to the last byte
      of the symbol in question - while objdump's --stop-address
      expects the last byte plus 1 to disassemble the full range.

      Arnaldo Carvalho de Melo 提交于
      The live annotation done in 'perf top' needs to limit the context before
      lines that aren't filtered out by the min percent filter, if we don't do
      that, the screen in a tty often is not enough for showing what is
      interesting: lines with hits and a few source code lines before it.

      Since we'll need it when implementing the live annotate TUI browser.
      
      This also simplifies things a bit by having the list head for the source
      code to be in the dynamicly allocated part of struct annotation, that
      way we don't have to pass it around, it can be found from the struct
      symbol that is passed everywhere.
