![]() ![]() The Linux 5.13 kernel also gets initial support for Intel’s upcoming 12th gen Alder Lake-S chips.Īn AMD fan? You may be pleased to know that pre-HDMI 2.1 connections now support AMD FreeSync, a feature previously limited to DisplayPort connections. This can down-clock processor cores when passing a lower thermal threshold than set by the default OS. Modern Intel CPUs gain a new cooling driver. This (rather wordy sounding feature) is pretty important as LWN note it “…means all software interrupts are handled in kernel threads, where they can be preempted by a higher-priority process like anything else”.Ī handful of noteworthy EXT4 filesystem tweaks include support for the FITRIM ioctl() command automatically overwriting directory entries when files get deleted and the ability to handle filesystems using case folding and encryption - all of which make using this file system (Ubuntu’s default) more reliable and more secure. This kernel update also intros mainline support for software-interrupt processing code from the realtime preemption tree. ![]() Also on the security front, a tweak to the kernel’s “trusted keys” feature allows key to originate from sources other than the TPM. This can be used alongside other Linux Security Modules, e.g., SELinux, to better control/restrict what running process can and can’t access. ![]() Linux 5.13 includes a new ‘ Landlock‘ security module. You can support the effort by contributing to the Patreon of Hector Martin. Expect further M1 improvements to fall from the tree in future kernel releases. That said, this debut dose of M1 code is a concrete step towards realising the dream of running Linux on Apple’s homegrown hardware. ![]() Linux support for Apple Silicon is still at a formative stage - but progress has to start somewhere You can’t download a distro based on Linux 5.13, install it on an M1 Mac, and expect everything to Just Work™ like it does for Intel and AMD hardware. This is the first version of the Linux kernel to offer support for the Apple M1 chip - but don’t get carried away here! Linux support for Apple Silicon is still at a formative stage. This ‘fairly large’ release is packed with changes ![]()
