PAPI_enum_cmp_event Class Reference

Enumerate PAPI preset or native events for a given component. More...

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 

    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\t\t\t Code\t Description\n" );
* do {
* retval = PAPI_get_event_info( i, &info );
* if ( retval == PAPI_OK ) {
* printf( "%-30s %#-10x\n%s\n", 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
