The recent AMD P-State Linux driver patches for heterogeneous core CPU topology, Fast CPPC, and Core Performance Boost haven't made it to the Linux power management's "-next" branch ahead of the imminent Linux 6.10 cycle. Thus it looks like those features won't be ready to make it for v6.10 unless by chance being deemed ready in the coming days and then sent in as part of a secondary set of merge window changes. However, some other AMD P-State fixes/improvements are queued up...
With the new Intel "Xe" Direct Rendering Manager kernel driver that's been in development one of the touted benefits of the clean sheet driver design is that it would enable using Intel discrete GPUs on non-x86 CPU architectures. The long-used "i915" DRM kernel graphics driver has many x86'isms in the code-base built up over the many years of Intel integrated graphics that were only ever found within their x86/x86_64 processors. But now in the era of Intel discrete graphics, there's been issues in trying to run Intel Arc Graphics on say ARM, POWER9, and RISC-V, among others. The experimental Intel Xe driver was recently successfully demonstrated in running on ARM using an Ampere Altra workstation...
