/* This file performs the following test: start, stop and
timer functionality for L1 related events
- They are counted in the default counting domain and default
granularity, depending on the platform. Usually this is
the user domain (PAPI_DOM_USER) and thread context (PAPI_GRN_THR).
- Start counters
- Do iterations
- Stop and read counters
