How to monitor core's read or write access information to pmm？

[Yxiaoge]

Remote/local DRAM access displayed in pcm-numa is at core granularity.

1. What should I do if I want to observe the access status at thread granularity? Could PCM monitor threads by thread_id as in perf?
2. What should I do if I want to observe the read/write access of each core to pmm

1. PCM does not support OS thread granularity.
2. Similar to the other question you can collect OFFCORE_RESPONSE PMM events for reads and writes (RFOs). I know they have gaps but a subset of them should give you an idea of the read/write distribution.
