Linux kernel 6.3 include a new DRM accelerated driver for Intel VPU (Versatile Processing Unit) that supports VPU IP 2.7 integrated into 14th Generation Intel “Meteor Lake” client CPUs, Rust code support for x86_64 user-mode Linux, AES-SHA2-based encryption for the NFS file system, and support for AMD’s “automatic IBRS” feature.
“It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment.” as quoted by Linus Torvalds.
Some quick highlights
- Improved Steam Deck hardware support.
- Improved support for the Logitech G923 Xbox Edition steering wheel.
- Work towards Intel Meteor Lake support.
- Automatic IBRS for AMD Zen 4, to improve Spectre V2 mitigations.
- Logitech B910 and C910 improvements for autosuspend functionality.
- Support for the Logitech MX Master 3S mouse.
- ASUS B650/B660/X670 board support improvements.
- Support for the 8BitDo Pro 2 Wired Controller.
- New power management drivers for ARM and RISC-V ship in Linux 6.3. The latter also picks up support for accelerated string functions (by way of the Zbb bit manipulation extension) and the former gains support for scalable matrix extension 2 instructions.
- In filesystems, the NFS filesystem (both the client and server sides) now supports AES-SHA2-based encryption; optimisations to EXT4 direct I/O performance; low-latency decompression for EROFS, and a faster Brtfs file-system driver.
How to download Linux Kernel 6.3
You can download Linux kernel 6.3 from the kernel.org website, but you’ll have to compile it by hand to actually do anything with it.
