As a warning and call for testing, old and "weird" laptops may broken backlight controls when moving to the Linux 6.1 kernel currently under development. Thus if invested in using an old laptop with a modern kernel version, it may be useful trying out a Linux 6.1 release candidate to help spot any regressions early...

While the Intel Alder Lake and now Raptor Lake hybrid processor support on Linux is in good shape after various improvements to the kernel for dealing with the mix of P and E cores, there are occasional caveats. Posted this week were a set of Intel P-State driver fixes around hardware P-states (HWP) calibration to ensure it's working on all Intel hybrid platforms...

At the start of the year SUSE's YaST team announced D-Installer as their new web-based distribution installer. Now as we approach the end of the year, D-Installer is ready for more widespread user testing and they are looking for help from the community in testing. Additionally, they are looking for help coming up with a new name for the "D-Installer"...

Earlier this month I wrote about AMD "Morgana" and "Glinda" SoCs appearing in Coreboot for this open-source system firmware implementation. These are codenames we haven't seen talked about previously by AMD and this week more of the AMD Glinda SoC code has been published and merged into Coreboot...

Work carried out by Google engineers and others around the Linux kernel's read-copy update (RCU) synchronization mechanism to make it "lazier" is helping with 5~10% power-savings for idle or lightly-loaded systems. This "Lazy RCU" work is likely to be merged for the Linux 6.2 kernel merge window in December...

Last week Intel began shipping their 13th Gen Core "Raptor Lake" processors. As noted in that launch-day article last week, unfortunately I wasn't able to deliver my usual Linux performance review in time due to hitting some DDR5 issues with my test platform, but those have now been resolved with a new Z790 motherboard. So as the first of my Raptor Lake Linux benchmarks, here is a look at how the top-end Core i9 13900K performs against the AMD Ryzen 7000 series on Ubuntu Linux along with the older Intel/AMD processors.

In recent months there has been a lot of RADV ray-tracing optimizations and improvements for maturing the ray-tracing support by this open-source Radeon Vulkan driver within Mesa. The RADV ray-tracing performance is about to take another step forward with a pending merge request providing a PLOC BVH builder that can improve the Quake II RTX performance by around 33%...

With the recent Linux 6.1 merge window there sadly weren't any Nouveau Direct Rendering Manager (DRM) driver improvements for getting the RTX 30 "Ampere" OpenGL support working yet with the mainline kernel even with RTX 40 series having launched. Needless to say, there also wasn't any progress on the re-clocking front for getting the GTX 900 series and later running in a performant manner on this open-source driver. But the Nouveau developers at Red Hat haven't simply been idling but rather have been working on the NVIDIA GPU System Processor (GSP) support for improving the RTX 20 "Turing" support and newer...

This sdl12-compat can allow for Wayland support if there is no other direct X11 usage by the software itself, native support for PipeWire, improved input controls, and the many other enhancements enjoyed with the much more modern SDL2 library. Released yesterday was sdl12-compat 1.2.60 as the newest stable release for this conversion/support library for vintage software...

A set of "x86/urgent" patches were sent out this morning for pulling into the Linux kernel ahead of today's 6.1-rc2 release...

There has long been a debate over an "accelerator" subsystem for the Linux kernel given the increasing number of AI/accelerator devices coming to market. Currently there are accelerator drivers living within the catch-all "char/misc" area of the kernel while some driver efforts have been focused on Direct Rendering Manager (DRM) subsystem integration given the commonality with GPUs and some of the core infrastructure and APIs being relevant for both GPUs and these dedicated accelerator ASICs. There finally seems to be some agreement over the future of the accelerator subsystem and some initial patches were mailed out this weekend...

A new Linux driver introduced by Intel earlier this year was the In-Field Scan for making use of new silicon failure testing functionality with upcoming Intel server CPUs. The IFS driver and associated hardware capability is for detecting potential problems not caught by parity or ECC checks on systems in production. In-Field Scan was merged in Linux 5.19 but then shortly thereafter the driver was marked "broken" due to some driver design issues coming to light. New patches for IFS have been posted to improve the driver's design and remove that "broken" tag...
