The development of Linux kernel 7.1 is gaining momentum, bringing a strategic blend of cleanup, modernization, and performance optimization. In an effort to streamline the codebase, the project is purging a series of obsolete drivers. This primarily affects input hardware from the 1990s, including support for bus mice, ISA add-in cards, and early touchpads. Simultaneously, the kernel is making room for innovation by integrating new drivers for Chrome OS keyboard extensions and Charlieplex GPIO keypads.
A significant portion of the update focuses on supporting upcoming hardware generations. The AMD Side Band Interface (SBI) driver has been updated to prepare for EPYC Venice platforms. This move is part of a broader set of preparations for Zen 6 processors, featuring new P-State functions and SMCA bank types. Laptop users also see substantial gains, with default doubletap enablement for Lenovo ThinkPad Trackpoints, expanded support for HP Omen and Bitland devices, enhanced Uniwill driver features for TUXEDO laptops, and new strobe LED support for Intel web cameras.
Performance benchmarks of the current Git state indicate that Linux 7.1 is performing well overall compared to the stable 7.0 release. Notable improvements have been observed in scheduling, networking, and database operations. Testing on AMD EPYC Zen 5 server processors highlights particular gains in high core count environments, although some regressions have been noted. These minor setbacks are expected to be addressed as the kernel moves toward its final stable release.
