With the incredible market demand around DDR5 memory and significantly elevated pricing on the more premium DDR5 memory modules, as part of the AMD Ryzen 7 9850X3D launch there's been some communication that thanks to 2nd Gen AMD 3D V-Cache, using lower memory speeds like DDR5-4800 can be suitable without much of an impact to the gaming performance. But what about for Linux gaming? And other workloads with the Ryzen 7 9850X3D? Complementing yesterday's Linux review of the Ryzen 7 9850X3D are benchmarks of DDR5-4800 vs. DDR5-6000 performance with Ubuntu Linux and this new 3D V-Cache 8-core / 16-thread desktop processor.

Timur Kristof of Valve's Linux graphics team last year addressed remaining issues in the open-source AMDGPU kernel graphics driver so old AMD GCN 1.0 and GCN 1.1 GPUs could transition to using AMDGPU by default rather than the former "Radeon" kernel driver that is largely in maintenance mode for pre-GCN/RDNA GPUs. One caveat though was the GCN 1.1 APU support still having some limitations leading to Kaveri and friends not being able to use the modern AMDGPU DC "Display Core" code. But new patches from Timur take care of those limitations...

Upstreamed to the Nouveau open-source kernel driver in Linux 6.19 was support for larger pages and with that compression support available with the larger page sizes. Subsequently the Mesa NVK open-source Vulkan driver began making use of the larger pages and compressed image support dependent upon the larger page sizes as it should help with performance. But for now it's being temporarily disabled due to a discovered issue...

While the Asahi Linux project has made good progress on bringing Linux to Apple Silicon hardware, much of the success and in turn upstreaming to the Linux kernel has been around the aging M1 and M2 Macs. Apple M3 and newer has been a struggle but progress is being made. One of the Asahi Linux developers shared the ability now to boot to the KDE Plasma desktop with the experimental Asahi Linux code on an M3 MacBook but without any GPU acceleration yet...

Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel. Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler's NEXT_BUDDY feature due to performance regressions. Here are some fresh benchmarks looking at the latest Linux 6.19 Git state with/without NEXT_BUDDY and comparing it to Linux 6.18 stable for reference.

A patch causing a healthy technical debate today on the Linux kernel mailing list would allow the kernel virtual terminal "VT" support to be enabled/disabled at boot time rather than being limited to the current CONFIG_VT build-time option...

Added to the LLVM 23 Git codebase minutes ago is a pull request adding the initial AMDGPU GFX13 target for their next-generation graphics core IP. AMD GFX13 is presumably for RDNA5...

A patch series posted last week for the open-source AMDGPU kernel driver implements HDMI Variable Rate Refresh "VRR" and other gaming features for HDMI displays. With the HDMI Forum blocking HDMI 2.1 open-source support, these HDMI gaming features for the AMDGPU driver were developed via trial-and-error and the limited public knowledge available. A second iteration of these patches are now available for testing...

For the Intel-powered LG Gram Style 14 laptop one of the Linux support caveats is the internal speakers not working properly under Linux, but with a patch expected for the upcoming Linux 6.20~7.0 kernel cycle it will finally fix the laptop speaker support for one of the laptop models in this series...
