In a separate development, SUSE could be sold by EQT for up to $6 billion, marking another potential ownership change.
Starting with Linux 7.1, the kernel will automatically power off systems upon fatal ACPI errors to comply with standards. AMD has enhanced its AMDGPU and AMDKFD drivers with support for DCN 4.2, GFX 12.1, and 57-bit memory addressing, while also enabling Display Core by default for GCN 1.1 APUs. Linux 7.0 introduced a performance optimization for epoll that boosts network throughput by 1.5% on AMD Zen 2 CPUs. Additionally, AMD has expanded its Ryzen AI Embedded P100 family with 8, 10, and 12-core processors based on Zen 5 architecture, targeting industrial, automotive, and edge computing markets with availability from Q3 2026.
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.
