I wonder that if
perf mem
can detect the remote memory access on CXL NUMA Nodes. I got an AMD-EPYC-9654 server, and CXL Mem is on the Numa Node 2. I run a task on node 0, which accessed the remote Node 2 memory continuously. But unfortunately I could not test on my machine, because perf mem didn't work on AMD CPUs (https://community.amd.com/t5/server-processors/issues-with-perf-mem-record/m-p/95270) .
Who can help me?
