LLVM developers and other stakeholders have begun debating the use of pre-compiled headers "PCH" as a means of speeding up the compiulation of the LLVM compiler infrastructure by 1.5x to 2x than with non-PCH builds.

A request for comments (RFC) pull request was opened last week over using pre-compiled headers to speed-up the LLVM build. Due to most time in LLVM builds being spent repeatedly parsing headers, PCH is being considered for frequently used header files like the C++

Back on the 1st Valve published the Steam Survey results for December 2025 and they put the Linux gaming marketshare at 3.19%, a 0.01% dip from November. But now the December results have been revised with a nice bump to the Linux marketshare.

The updated Steam Survey results for December put the Linux marketshare at 3.58%, a 0.38% increase over November. Valve didn't publish any explanation for the revision but occasionally they do

Open-source developer Sebastian Wick has written a blog post outlining work to improve the graphics driver situation for Flatpaks. Particularly around situations like the NVIDIA driver stack that may depend upon a specific kernel version or where a Flatpak runtime may be end-of-life, dealing with GPU drivers in Flatpaks can be a burden. A solution being explored is GPU virtualization to deal with those GPU driver handling challenges while still providing robust and secure GPU access.

GPU virtualization is being explored by leveraging VirtIO-GPU and Mesa Venus to

Last year AMD announced GAIA as short for "Generative AI Is Awesome" . It started off as a Windows-only AI demo but over time added Linux support along with introducing different AI agents . For going along with AMD's AI announcements at CES 2026 , AMD released GAIA 0.15 where they are now positioning this software as a framework/SDK for building AI PC agents.

AMD is positioning their GAIA project as an "AI agent framework" in being " a pure framework/SDK

Yesterday when Intel formally introduced Panther Lake as the Core Ultra Series 3 with pre-orders set to begin today and available globally later this month, one of the key questions remaining was around pricing... I've been scouting various Internet retailers today and so far have found a Ultra X7 358H model with the 12 Xe cores for the Xe3 integrated graphics to be priced around $1299 USD with 32GB of RAM.

For those curious about Panther Lake pricing,

On Monday the first release candidate of the GStreamer 1.28 multimedia framework was released. As is a recurring focus in recent releases, more GStreamer code is written in Rust for memory safety especially around decoding content.

GStreamer 1.28-RC1 introduces a new GIF decoder written in the Rust programming language. The GStreamer 1.28 release also brings a new YOLOX tensor decoder written in Rust along with a new audio source separation element and a new Icecastsink element with AAC support.

In addition to the

Intel just hosted their CES keynote where they formally launched Panther Lake as the Core Ultra Series 3 SoCs.

Much of the Panther Lake details were previously shared back at their Tech Tour in Arizona: Intel Showcased Panther Lake & Xe3 Graphics At Tech Tour Arizona 2025 . For CES 2026 I wasn't briefed in advance by Intel but here are my quick notes from their keynote. Still awaiting Core Ultra Series 3 Panther Lake hardware at Phoronix as well for Linux compatibility testing and performance benchmarking,

Back in November AMD began posting open-source Linux graphics driver patches for some next-gen graphics IP. Those IP block patches were for MMHUB, PSP, and other blocks making up modern AMD GPUs. The GFXHUB patch pointed it to being part of the GFX12 / RDNA4 family. Out today are new patches for enabling the SMU15 IP and an interesting takeaway there is some apparent NPU integration for future Radeon graphics.

Posted to the public mailing lists today were enablement patches in the AMDGPU kernel graphics
