Recent Linux Kernel Features Relevant to System Design

Every new version of the Linux kernel provides changes that have an immediate influence on hardware interaction, memory efficiency, system speed, and security. These developments are very relevant not just to huge business servers but also to embedded systems, multimedia platforms, and real-time gadgets. The need to support increasingly complex hardware, provide more secure abstractions, and lower overhead drives kernel development. A technical overview of a number of new features that meet these needs is given in this document: SOF Dynamic Pipeline Support, io_uring, DAMON, Landlock LSM,memfd_secret, and IOMMU FD API. Each is described along with its purpose, relevant system design scenarios, and possible real-world applications.
