Some upstream Intel platform updates are included in UEK 8. Notable items include:

• Intel Software Guard Extensions (SGX2), a hardware-based implementation of Enclave Dynamic Memory Management (EDMM), is an enhanced version of a security technology that can protect sensitive data and code by isolating them in private memory regions called enclaves. SGX2 introduces new features such as dynamic memory management, so that enclaves can resize and manage their memory during runtime. This update is important for applications with dynamic workloads or larger memory requirements, that require a more scalable architecture. SGX2 provides robust confidentiality and integrity for sensitive workloads in both on-premises and cloud environments.

• Quick Assist Technology (QAT) functionality is updated to support 4th Gen Intel Xeon processors.
