PAPI_enum_cmp_event(3) Enumerate PAPI preset or native events for a given component.

SYNOPSIS


Detailed Description

@par C Interface:
#include <papi.h> @n
int PAPI_enum_cmp_event( int *EventCode, int  modifer, int cidx );
Given an event code, PAPI_enum_event replaces the event 
code with the next available event.
The modifier argument affects which events are returned. 
For all platforms and event types, a value of PAPI_ENUM_ALL (zero) 
directs the function to return all possible events. @n
For native events, the effect of the modifier argument may be
   different on each platform. 
See the discussion below for platform-specific definitions.
@param *EventCode
    A defined preset or native event such as PAPI_TOT_INS.
@param modifier 
    Modifies the search logic. See below for full list.
    For native events, each platform behaves differently. 
    See platform-specific documentation for details.
   @param cidx
           Specifies the component to search in 
@retval PAPI_ENOEVNT 
    The next requested PAPI preset or native event is not available on 
    the underlying hardware.
@par Examples:


  

*   // Scan for all supported native events on the first component
*   printf( "Name			       Code	   Description );
*   do {
*       retval = PAPI_get_event_info( i, &info );
*       if ( retval == PAPI_OK ) {
*       printf( "%-30s %#-10xs, info.symbol, info.event_code, info.long_descr );
*       }
*   } while ( PAPI_enum_cmp_event( &i, PAPI_ENUM_ALL, 0 ) == PAPI_OK );
*

Generic Modifiers

The following values are implemented for preset events

  • PAPI_ENUM_EVENTS -- Enumerate all (default)
  • PAPI_ENUM_FIRST -- Enumerate first event (preset or native) preset/native chosen based on type of EventCode

Native Modifiers

The following values are implemented for native events

  • PAPI_NTV_ENUM_UMASKS -- Given an event, iterate through possible umasks one at a time
  • PAPI_NTV_ENUM_UMASK_COMBOS -- Given an event, iterate through all possible combinations of umasks. This is not implemented on libpfm4.

Preset Modifiers

The following values are implemented for preset events

  • PAPI_PRESET_ENUM_AVAIL -- enumerate only available presets
  • PAPI_PRESET_ENUM_MSC -- Miscellaneous preset events
  • PAPI_PRESET_ENUM_INS -- Instruction related preset events
  • PAPI_PRESET_ENUM_IDL -- Stalled or Idle preset events
  • PAPI_PRESET_ENUM_BR -- Branch related preset events
  • PAPI_PRESET_ENUM_CND -- Conditional preset events
  • PAPI_PRESET_ENUM_MEM -- Memory related preset events
  • PAPI_PRESET_ENUM_CACH -- Cache related preset events
  • PAPI_PRESET_ENUM_L1 -- L1 cache related preset events
  • PAPI_PRESET_ENUM_L2 -- L2 cache related preset events
  • PAPI_PRESET_ENUM_L3 -- L3 cache related preset events
  • PAPI_PRESET_ENUM_TLB -- Translation Lookaside Buffer events
  • PAPI_PRESET_ENUM_FP -- Floating Point related preset events

ITANIUM Modifiers

The following values are implemented for modifier on Itanium:

  • PAPI_NTV_ENUM_IARR - Enumerate IAR (instruction address ranging) events
  • PAPI_NTV_ENUM_DARR - Enumerate DAR (data address ranging) events
  • PAPI_NTV_ENUM_OPCM - Enumerate OPC (opcode matching) events
  • PAPI_NTV_ENUM_IEAR - Enumerate IEAR (instr event address register) events
  • PAPI_NTV_ENUM_DEAR - Enumerate DEAR (data event address register) events

POWER Modifiers

The following values are implemented for POWER

  • PAPI_NTV_ENUM_GROUPS - Enumerate groups to which an event belongs
