I am trying to execute an AMX instruction inside an SGX enclave. I am using RHEL 9.3. I have confirmed that I can run an AMX instruction outside of an enclave, but not inside it when initializing AMX outside of the enclave. Executing the enclaved code returns error code 0x1006. I can't reinitialize AMX inside the enclave because it requires a system call, and system calls are impossible inside an SGX enclave. Is there any way to run AMX inside an enclave? I have attached a minimal reproducible example.
It is based off the code here and here
