Linux 5.12 Kernel Officially Released, This Is What’s New


Linus Torvalds officially released today the Linux 5.12 as the latest and greatest kernel series for Linux-based operating systems, bringing numerous new features and improvements for better hardware support.

More than two months in the works, Linux kernel 5.12 is here with dynamic thermal power management mechanism, support for LTO in Clang, initial support for zoned block devices for the Btrfs file system, netfilter improvements, high compression LZ4 mode support for the F2FS file system, and support for non-uniform memory access (NUMA) systems for the RISC-V 64-bit architecture.

KFENCE (Kernel Electric-Fence), a new memory-debugging tool, has been added as well in Linux 5.12, which now supports the open source ACRN reference hypervisor designed for embedded IoT development, kernel thread-based NAPI polling, ID mapping in mounts, Playstation 5 DualSense wireless game controllers, Nintendo 64 game controllers, and the the Lenovo ThinkPad X1 Tablet Gen 2.

Among other interesting new features, Linux 5.12 brings eMMC inline encryption support, Linux root partition support for Microsoft Hypervisor, better support for Microsoft Surface devices, and last but not least, my favorite changes, support for the Lenovo IdeaPad platform profile, along with keyboard backlight control support, always-on USB charging control support, and reenable touchpad control.
