    perf, x86, Pentium4: Add RAW events verification · c9cf4a01
    Cyrill Gorcunov authored
    Implements verification of
    
    - Bits of ESCR EventMask field (meaningful bits in field are hardware
      predefined and others bits should be set to zero)
    
    - INSTR_COMPLETED event (it is available on predefined cpu model only)
    
    - Thread shared events (they should be guarded by "perf_event_paranoid"
      sysctl due to security reason). The side effect of this action is
      that PERF_COUNT_HW_BUS_CYCLES become a "paranoid" general event.
