Is it possible to use CMT inside SGX enclave?

[AmbitionXiang]

If results of CMT can only be gotten through untrusted OS, enclaves cannot trust the results. Is it possible to directly get the results inside enclaves without involving OS?

I don't think SGX deals with aspects of host OS provided telemetry. CMT is no different to metrics obtained through perf subsystem.
Why do you need CMT capability inside a VM/SGX enclave? Is there a practical application for it?

Thank you for your reply! I'm thinking about...maybe we can construct an oblivious memory by combining CMT and CAT if they are compatible with SGX.
