Support the latest DCAP driver.

[qinkunbao]

mystikos only supports Intel DCAP driver version 1.7. The latest Intel DCAP driver is 1.11.

Do you have any plan to support the latest version of Intel DCAP (dev/sgx_enclave and /dev/sgx_provision)?

Are you using Ubuntu 18.04 or Ubuntu 20.04? We test using the versions of drivers available for the Azure canonical images. Azure Canonical Ubuntu 18.04 uses 5.4 kernel. On Ubuntu 20.04, Azure Canonical has 5.8 kernel and will get the 5.11 kernel in the future and will have the latest DCAP driver. Open Enclave is on 1.10.103.1 for Ubuntu 18.04

Thank you for your reply. I am using Ubuntu 18.04. The DCAP driver has been merged into the kernel (5.11 or higher).
