Earlier this summer was the patch series for GNOME's Mutter to make use of the Linux DRM/KMS "max BPC" property for the drivers exposing the maximum bits per color supported. That code has now been merged in time for next month's GNOME 43 release and in turn will help deal with some scenarios where users may encounter screen flickering, brief blackouts, and other problems related to available monitor bandwidth...

Alyssa Rosenzweig who is known for her work on the Panfrost open-source, reverse-engineered Arm Mali driver and has been spending nearly two years now involved with the Asahi Linux crew working on reverse-engineered Apple M1/M2 graphics support has shared a new status update...

With this weekend having seen more Zink refactoring code land and Zink being faster than RadeonSI at least for some operations, it was time to fire up some fresh benchmarks of this generic OpenGL-on-Vulkan implementation. From the newest Mesa code this weekend after the latest Zink patches were merged, here is a look at how the Zink performance is compared to the RadeonSI Gallium3D driver's native OpenGL support. All of the testing was done using an AMD Radeon RX 6800 XT graphics card.

Last week Canonical announced official Ubuntu RISC-V images for the StarFive VisionFive board while this week they are expanding their supported RISC-V line-up to also include the Nezha single board computer powered by the Allwinner D1 SoC...

For the past decade going back to the early GTK3 days there has been the "Broadway" back-end that allows for GTK interfaces to be rendered within HTML5 web browsers. Aside from demos and other toys, there hasn't been too much widespread use reported with this GTK HTML5 back-end and some distributions like Ubuntu and Debian haven't been shipping the Broadway support with the newer GTK4. However, that is changing now for Debian and with this autumn's release of Ubuntu 22.10...

For those making use of Kexec reboots for booting to a new kernel without fully bringing down the system to reduce the server downtime from POST'ing and other hardware initialization tasks, Kexec reboots may soon be much faster on 64-bit Arm and RISC-V systems...

In addition to the R300g driver seeing new shader optimizations, also being merged this week to Mesa 22.3 were some fixes for the recently-introduced new NIR back-end for the Rade R600 Gallium3D driver for the Radeon HD 2000/3000/4000 series...

The open-source NVIDIA Vulkan driver "NVK" being developed for Mesa has seen a busy week of new development activity on this work-in-progress solution...

Thanks to being open-source, the Mesa R300 Gallium3D driver that is used for supporting OpenGL on the ATI Radeon 9500/9600/9700/9800 series up through the Radeon X1000 "R500" series has seen a new set of performance optimization work twenty years after the R300 GPUs first shipped...

Cloud Hypervisor 26.0 released this week as the newest version of this Rust-based hypervisor focused on cloud workloads and secure computing. The open-source Cloud Hypervisor started out as an Intel software project and continues to be led by them while now under Linux Foundation stewardship and continuing to see contributions from the likes of Arm and Microsoft...

Intel's open-source Linux bring-up for Meteor Lake continues. The latest open-source patches on the Meteor Lake front are for the Intel Graphics Compiler (IGC) changes for these 14th Gen CPU graphics...

The latest Mesa 22.3-devel code for Zink's OpenGL on Vulkan implementation has hit an important milestone with the latest code refactoring: it looks like this OpenGL implementation atop the Vulkan API with the RADV driver is beginning to outpace AMD's RadeonSI Gallium3D driver providing native OpenGL support for Radeon GPUs...

KDE developers had another busy summertime week adding more features to their open-source desktop environment...

SDL 2.24 has been released as the newest update to this widely-used abstraction layer library commonly used by cross-platform games, including heavily by games on Steam...

Last week I published initial Apple M2 vs. AMD Rembrandt vs. Intel Alder Lake Linux benchmarks using Asahi Linux and Arch Linux across the board. For ending out this week, here is a follow-up article looking more closely at the Apple M2 in the MacBook Air against the AMD Ryzen 7 PRO 6850U "Rembrandt" within the Lenovo ThinkPad X13 Gen3. This time around are also results from performance tweaks to each laptop for the CPUFreq governor and platform profile.
