For the upcoming Linux 6.17 kernel cycle AMD already queued fixes for GPU compute on some older AMD hardware, improved debugging support for AMDGPU, and other enhancements. Sent out today was a final batch of feature changes for AMDGPU/AMDKFD expected for the upcoming Linux 6.17 merge window. Most notable is AMD SmartMux support coming to Linux...

The first release candidate of LLVM 21.1 is now available for testing, which under their modern versioning scheme will represent the first stable version of the LLVM 21 compiler stack...

For those using an AMD Radeon RX 500 "Polaris" graphics card on Linux and routinely suspend/resume your system, going into the Linux 6.16 kernel and then to be back-ported to the stable series is a fix where the AMDGPU driver could end up producing a lot of spam in the kernel log...

Some commits merged today to FFmpeg Git provide additional hand-tuned Assembly code for AVX-512 with capable Intel and AMD processors...

Mesa 25.2 entered its feature freeze yesterday with many exciting driver improvements with new features and performance optimizations while one feature that wasn't ready for merging in this quarter's release is Magma, which is a recent effort by Google engineers working on a cross-platform system call interface for Mesa. And it's written in Rust...

The long in development work around proxy execution for the Linux kernel appears to be ready for the upcoming Linux 6.17 merge window with the Single RunQueue Proxy Execution patches queued into a TIP branch after going through 19 rounds of patch review/revisions...

Launched back in 2014 was the Marvell PXA1908 SoC intended for 4G LTE smartphones and featured four Arm Cortex-A53 cores. Not too impressive for its time and far less so today. Though after a decade of not seeing mainline Linux kernel support and some vendor kernels stuck in the Linux 3.14 era, the upcoming Linux 6.17 cycle is expected to upstream support for this old smartphone SoC...

While late in the Linux 6.16 cycle and hitting the cut-off for when the period to queue new DRM driver feature material for Linux 6.17 ends, an additional drm-misc-next pull request was sent out today with some last minute kernel graphics driver changes for this next kernel cycle. Motivating this extra pull were the recent AMDGPU system hibernation patches...

In addition to releasing Mesa 25.2-rc1 with its many new features to test, Mesa release manager Eric Engestrom today released Mesa 25.1.6 as the newest bi-weekly stable point release for last quarter's series...

Earlier this year when the Framework 13 was updated for the AMD Ryzen AI 300 series I ran benchmarks looking at the performance gains across different Linux distributions with Debian 13, Clear Linux, and CachyOS being the outstanding performers for that Strix Point hardware. With the recent launch of the Framework 12 2-in-1 laptop powered by Intel Raptor Lake you may be wondering what Linux distributions have the edge there. Here is an eight-way comparison of different Linux operating systems on the Framework 12 with Intel Core i5 1334U with the likes of Arch Linux, CachyOS, Clear Linux, Debian, Fedora, openSUSE, and Ubuntu.

Mesa 25.2 is now branched and thus under a feature freeze and with Mesa 25.2-rc1 having just been released. This marks the start of weekly release candidates until the Mesa 25.2 stable release is ready to ship sometime in August...

Similar to the 3D class header files previously open-sourced by NVIDIA for prior generation GPUs, yesterday NVIDIA carried out a similar open-source move to publish all the 3D class header files for their newest Blackwell graphics processors...

It's a very busy week for the open-source OpenGL and Vulkan drivers leading up to the Mesa 25.2 code branching. On top of RADV ray-tracing improvements, Vulkan 1.2 conformance for Kepler GPUs, Xe3 Panther Lake graphics enabled by default, and many other last minute changes, over the past week has also been a push getting more AMD FidelityFX Super Resolution 4 "FSR 4" improvements merged for the Radeon RADV driver...

One of the early changes for the LLVM 22 compiler stack now in development is completing the removal of support for Google's Native Client "NaCl"...

Canonical announced today that they teamed up with ESWIN Computing to ship Ubuntu Linux as the preferred operating system on their ESWIN Computing EBC77 Series single board computer...

The Intel Media Driver is out with its quarterly feature release for bringing all of the latest open-source video acceleration improvements for Intel graphics hardware on Linux. Enhancing support for upcoming Panther Lake SoCs continues to be a primary focus...

Hyprland 0.50 is out today as the newest feature release for this Wayland compositor focused on delivering a lot of Linux desktop bling...

Yet more feature code continues piling in for the Mesa 25.2 release due out next month and days ahead of the feature freeze. Hitting Mesa Git this evening is now treating NVIDIA Kepler GPUs as Vulkan 1.2 conformant following the Vulkan 1.2 CTS passing with the NVK open-source driver paired with the Nouveau kernel driver...

Ahead of the Mesa 25.2 feature freeze and code branching expected later this week, some additional ray-tracing optimizations were merged today for the Radeon "RADV" Vulkan driver. These latest RADV ray-tracing improvements benefit the latest Radeon RX 9000 series "RDNA4" the most but there are also some optimizations too for RDNA3 class GPUs...

The upcoming Linux 6.17 kernel is going to be an especially nice release for users of modern Intel graphics hardware on Linux. The very latest feature being enabled for this next Linux kernel version is SR-IOV for Battlemage GPUs to vastly enhance the Intel Linux graphics experience in virtualized environments...
