Here is the list of hardware events I think the PAT should provide as
default.
1. Level 1 instruction cache misses         (PAPI_L1_ICM)
2. Level 1 instruction cache hits           (PAPI_L1_ICH)
3. Level 2 data cache misses                (PAPI_L2_DCM)
4. Level 2 data cache hits                  (PAPI_L2_DCH)
5. Total TLB misses                         (PAPI_TLB_TL)
6. Cycles stalled waiting for memory access (PAPI_MEM_SCY)
7. Total instructions executed              (PAPI_TOT_INS)
8. Integer instructions executed            (PAPI_INT_INS)
9. Floating point instructions executed     (PAPI_FP_INS)
10. Load instructions executed              (PAPI_LD_INS)
11. Store instructions executed             (PAPI_SR_INS)
