PAPI_disable_component_by_name() allows the user to disable a component before PAPI_library_init() time. This is useful if the user knows
they do not with to use events from that component and want to reduce the PAPI library overhead.
PAPI_disable_component_by_name() must be called before PAPI_library_init().

PAPI_set_domain(3) PAPI PAPI_set_domain(3)NAME
PAPI_set_domain -
Set the default counting domain for new event sets bound to the cpu component.
SYNOPSIS Detailed Description
@par C Prototype:
int PAPI_set_domain( int domain );
@param domain one of the following constants as defined in the papi.h header file
@arg PAPI_DOM_USER User context counted
@arg PAPI_DOM_KERNEL Kernel/OS context counted
@arg PAPI_DOM_OTHER Exception/transient mode counted
@arg PAPI_DOM_SUPERVISOR Supervisor/hypervisor context counted
@arg PAPI_DOM_ALL All above contexts counted
@arg PAPI_DOM_MIN The smallest available context
@arg PAPI_DOM_MAX The largest available context
Return values:
PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid.
PAPI_set_domain sets the default counting domain for all new event sets created by PAPI_create_eventset in all threads. This call
implicitly sets the domain for the cpu component (component 0) and is included to preserve backward compatibility.
Example:
int ret;
// Initialize the library
ret = PAPI_library_init(PAPI_VER_CURRENT);
if (ret > 0 && ret != PAPI_VER_CURRENT) {
fprintf(stderr,"PAPI library version mismatch!0);
exit(1);
}
if (ret < 0) handle_error(ret);
// Set the default domain for the cpu component
ret = PAPI_set_domain(PAPI_DOM_KERNEL);
if (ret != PAPI_OK) handle_error(ret);
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
