PAPI_enum_cmp_event(3) PAPI PAPI_enum_cmp_event(3)NAMEPAPI_enum_cmp_event-
Enumerate PAPI preset or native events for a given component.
SYNOPSISDetailed Description
C Interface:
#include <papi.h>
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.
For native events, the effect of the modifier argument may be different
on each platform. See the discussion below for platform-specific
definitions.
Parameters:
*EventCode A defined preset or native event such as PAPI_TOT_INS.
modifier Modifies the search logic. See below for full list. For
native events, each platform behaves differently. See platform-
specific documentation for details.
cidx Specifies the component to search in
Return values:
PAPI_ENOEVNT The next requested PAPI preset or native event is not
available on the underlying hardware.
Examples:
// Scan for all supported native events on the first component
printf( 'Name Code Description0 );
do {
retval = PAPI_get_event_info( i, &info );
if ( retval == PAPI_OK ) {
printf( '%-30s 0x%-10x1s0, 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
