Upstreamed at the start of the year was the Imagination PowerVR open-source DRM kernel driver for newer Imagination Rogue GPUs. That upstream kernel driver is now being extended to cover the Imagination BXS-4-64 MC1 GPU.

Merged back in 2019 was the Fieldbus subsystem as a set of network protocols for real-time distributed control of automated industrial systems. But now five years later, Fieldbus is being removed from the mainline Linux kernel since the code hasn't been maintained.

Due to the possibility of DMA attacks from connected Thunderbolt devices, Linux and other platforms have built up safeguards over the years and different security levels for Thunderbolt to better protect systems having this high speed interface exposing PCIe. With the upcoming Linux 6.13 kernel, the logic of the kernel is being enhanced to better detect and trust built-in Thunderbolt controllers.

LXQt 2.1 is now available as the latest feature release to this Qt-based lightweight desktop environment. Most significant with LXQt 2.1 is the introduction of the lxqt-wayland-session component.

Queued up over the past month into DRM-Next ahead of the Linux 6.13 kernel cycle has been initial support for Xe3 graphics to be found with Panther Lake processors. The initial Xe3 graphics driver support patches have been trickling in while the final drm-intel-next pull ahead of the Linux 6.13 merge window has readied support for actually being able to light up a display connected to Xe3 LPD graphics with Panther Lake.

The x86-simd-sort project from Intel has been an interesting open-source software effort for much faster number sorting by using AVX-512. There's been lightning fast number sorting with AVX-512 and AVX2 code paths also added to broaden the appeal in helping CPUs without AVX-512. Projects like Numpy have been making use of this library while today x86-simd-sort 6.0 was released and also comes a few days after PyTorch has begun using this library too.

With this week's release of SVT-AV1 2.3 for open-source AV1 encoding citing significant performance improvements for running on ARM, I was eager to see how well this AV1 encoder would be performing on the new System76 Thelio Astra ARM developer desktop powered by Ampere Altra. Here are some benchmarks showing those big speed-ups for ARM-based AV1 encoding.

While the mainline Linux kernel has begun seeing initial support for various Snapdragon X1 Elite laptops, various feature limitations are outstanding before these Qualcomm-powered laptops really become usable for daily use. For instance, just a few days ago the audio firmware was finally upstreamed to make setting up X1 Elite laptops easier. Another important feature as an example is CPUFreq driver support for CPU frequency scaling to ensure optimal performance and power efficiency.
