Linux 5.9 is the latest mainline kernel release to be issued. There’s better management of anonymous memory and a new slab memory controller that leads to lower overall kernel memory usage; while support for ZSTD-compressed kernel, ramdisk, and initramfs in the kernel boot process provides opportunities for faster boot times. Support for the upcoming Radeon RX 6000 RDNA 2, Intel Xe and Intel Rocket Lake graphics; overdue inclusion of Intel FSGSBASE support (offering possible performance improvements on Ivy Bridge style chips); and there’s been more effort expended to support USB 4.0. Schedutil is now the default CPU frequency scaling governor for ARM/ARM64; NVIDIA’s Tegra X1 and X2 SoCs now have working audio; a raft of single-boards (old and new) pick up support, including Lenovo’s IdeaPad Duet (an upcoming Chromebook based on the MT8183 (Helio P60t) SoC) and Allwinner sunxi revision v1.2 used in the recent versions of Pine64’s PinePhone. File-system tweaks also feature in Linux 5.9. The BTRFS, XFS, ext4, and F2FS file systems are among those gaining patches. https://www.omgubuntu.co.uk/2020/10/linux-5-9-kernel-featureske ......................................................................... #opensource #technology #linux #news
