    Phoronix: Intel SGX2 / Enclave Dynamic Memory Management Patches Posted For Linux

    While Intel's Software Guard Extensions (SGX) functionality has been present in CPUs going back to Skylake, it took until last year with Linux 5.11 for SGX support to finally be mainlined and required more than 40 rounds of review/revisions.
