      perf trace: Add interface to access perf data from Perl handlers · d1b93772
      Tom Zanussi 提交于
      The Perl scripting support for perf trace allows most of a trace
      event's data to be accessed directly as handler arguments, but
      not all of it e.g. the less common fields aren't passed in.  To
      give scripts access to the other fields and/or any other data or
      metadata in the main perf executable that might be useful, a way
      to access the C data in perf from Perl is needed; this patch
      uses the Perl XS facility to do it for the common_xxx event
      fields not passed to handler functions.
      
      Context.pm exports three functions to Perl scripts that access
      fields for the current event by calling back into perf:
      common_pc(), common_flags() and common_lock_depth().  Support
      for common_flags() field values was added to Core.pm and a
      script used to sanity check these and other basic scripting
      features, check-perf-trace.pl, was also added.
