More than two months in the works, Linux kernel 5.12 is here with dynamic thermal power management mechanism, 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, 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, Playstation 5 DualSense wireless game controllers, Nintendo 64 game controllers, and the the Lenovo ThinkPad X1 Tablet Gen 2.
