Linux 6.13 Released with AutoFDO and Propeller, AMD Changes and Apple Support

Linux 6.13 has been officially released, introducing several significant features and optimizations. This release includes the AMD 3D V-Cache Optimizer driver, which enhances performance for multi-CCD Ryzen X3D processors, and the AMD EPYC 9005 "Turin" server processors now default to AMD P-State for improved power efficiency. Additionally, the kernel supports Intel Xe3 graphics and many older Apple devices, including various iPads and iPhones. The update also incorporates NVMe 2.1 specification support and optimizations for compiling the kernel with the LLVM Clang compiler, specifically AutoFDO and Propeller. Furthermore, there is an expansion of Rust programming language infrastructure. Notably, the release also addressed a last-minute fix for EEVDF scheduling lag and disabled the EXECMEM_ROX support on x86_64, which had generated some controversy. With the stable release of Linux 6.13, the development cycle for Linux 6.14 has commenced, promising further enhancements and features.
