Intel is enhancing its Linux integration with features like Linear Address Masking and Directed Package Thermal Interrupts to support future security technologies such as ChkTag and improved thermal management. Meanwhile, the Linux kernel is preparing for IBPB-on-Entry support in AMD SEV-SNP guest virtual machines to defend against speculative execution attacks. In parallel, Nvidia continues to dominate the dedicated desktop graphics card market with a 94% share, despite a 4.5% decline in quarterly sales. These developments highlight the convergence of hardware innovation, software security, and market dynamics shaping the future of computing.
Linux 7.0-rc3 Released: Major Updates for AMD and Intel CPUs, Drivers, and Security
Linux 7.0-rc3 has been released, marking one of the largest release candidates in recent history. It includes significant updates for AMDXDNA Ryzen AI drivers, graphics drivers, and security and performance enhancements for both Intel and AMD CPUs. Linus Torvalds noted the unusually large size due to a backlog of contributions. The kernel will serve as the default for Ubuntu 26.04 LTS and Fedora 44, with ongoing testing to stabilize it before the final release.
Lenovo and AMD Advance AI and Edge Computing with New Solutions, Drivers, and Consortium
Lenovo has launched a new generation of AI-driven ThinkEdge solutions, including compact gateways, high-performance edge computers, and its first industrial all-in-one panel PC, enabling localized AI for industrial applications. Meanwhile, AMD has released the VEK385 Evaluation Kit for its Versal AI Edge Series Gen 2, supporting embedded AI, vision, and control systems with 4K/8K video processing, and has published Linux kernel patches to enhance virtual machine security via SEV-SNP BTB isolation. The modern AMD graphics driver in Linux 7.0 has surpassed six million lines of code, making it the largest single driver in the kernel. Additionally, Arm and Linaro have launched the CoreCollective consortium, with founding members including AMD, Google, and Microsoft, to advance open-source development in data centers, edge computing, and confidential computing.
Linux 7.0: New Security Features, File System Improvements, and Ceph Support
Linux 7.0 introduces key updates including user-space control-flow integrity (CFI) support for RISC-V to enhance security against ROP attacks, alongside an optimized strlen implementation. The NTFS3 driver gains improvements such as better readahead, fsync optimizations, and delayed allocation support, while the competing NTFS Remake driver continues development. AppArmor receives enhancements like per-permission tagging and execpath in user namespaces, improving security and debugging. Additionally, the Linux 7.0 kernel adds AES256K key support for Ceph authentication based on Kerberos 5 / AES256-CTS-HMAC384-192, expanding Ceph's encryption capabilities.
