sgx dcap out-of-tree driver
The SGXDataCenterAttestationPrimitives project maintains an out-of-tree driver for the Linux* Intel(R) SGX software stack, which will be used until the driver upstreaming process is complete. It is used on the platforms with Flexible Launch Control and Intel(R) AES New Instructions support and could support both Elliptic Curve Digital Signature algorithm (ECDSA) based attestation and Enhanced Privacy Identification (EPID) based attestation.
The linux-sgx-driver project hosts the other out-of-tree driver for the Linux* Intel(R) SGX software stack, which will be used until the driver upstreaming process is complete. It is used to support Enhanced Privacy Identification (EPID) based attestation on the platforms without Flexible Launch Control.
Intel(R) SGX driver package is for Intel(R) SGX DCAP and is derived from the upstream version of the SGX driver

Ensure that you have the following required hardware:
- 8th Generation Intel(R) Core(TM) Processor or newer with Flexible Launch Control and Intel(R) AES New Instructions support*
- Intel(R) Atom(TM) Processor with Flexible Launch Control and Intel(R) AES New Instructions support*
