PAPI_enum_event (3) - Linux Manuals


PAPI_enum_event -

Enumerate PAPI preset or native events.


Detailed Description

@par C Interface:
#include <papi.h> @n
int PAPI_enum_event( int * EventCode, int  modifer );

Given a preset or native event code, PAPI_enum_event replaces the event 
code with the next available event in either the preset or native table. 
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 preset events, a TRUE (non-zero) value currently directs the function 
to return event codes only for PAPI preset events available on this platform. 
This may change in the future. 
For native events, the effect of the modifier argument is 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.

    The next requested PAPI preset or native event is not available on 
    the underlying hardware.

@par Examples:


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