Only remote/local DRAM access is displayed in pcm-numa. What should I do if I want to observe the access status of pmm? |

you can use pmu-query.py to query MEM_LOAD_RETIRED.LOCAL_PMM and MEM_LOAD_L3_MISS_RETIRED.REMOTE_PMM event encodings and then use them in pcm-core utility. This should give at least the distribution of local/remote loads for PMM. |
