Intel News Archives

Intel Linux software engineers have recently been busy working on Wildcat Lake support primarily for the kernel drivers while now that work has been extended to Mesa for the Intel Iris Gallium3D (OpenGL) and ANV Vulkan drivers.

The most depressing news of the week: Intel is ending their performance-optimized Clear Linux distribution. Over the past decade the Clear Linux operating system has shown what's possible with out-of-the-box performance on x86_64 hardware... Not just for Intel platforms but even showing extremely great performance results on AMD x86_64 too. But with the cost-cutting going on at Intel, Clear Linux is now being sunset.

Intel is out today with its monthly feature update to the Compute Runtime as their open-source GPU compute stack providing Level Zero and OpenCL API support on Windows and Linux systems. This month there is new hardware support, more performance optimizations, and some new features.

Intel engineers yesterday released QATlib 25.08 as the first new update in nearly one year for this QuickAssist Technology library. Intel QuickAssist allows hardware-accelerated offloading of various security authentication and compression operations from the CPU onto dedicated accelerator IP found in recent Xeon processors. Intel's QATlib is the open-source library for enabling that magic to happen from the user-space side.

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.

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.

While the Intel Media SDK with VA-API has long supported accelerated video decoding, the latest Mesa 25.2 development code has now landed support for AV1 decoding using the Vulkan Video API with the Intel ANV driver for Xe2 Battlemage / Lunar Lake graphics and Gfx125 Xe graphics too.

The latest round of cost-cutting at Intel seems to be having a larger impact on their software engineering efforts than some of their previous rounds of layoffs. In addition to a prominent Linux kernel developer veteran leaving Intel last week where he worked for the past 14 years and responsible for many great upstream improvements, other Intel software engineers working on their Linux/open-source affairs have also been departing. In just the latest instance, one of the upstream Intel Linux kernel drivers is now "orphaned" due to the developer departing and no one experienced left to maintain the code.

With the upcoming Linux 6.17 kernel the Intel Xe kernel graphics driver is enabling Panther Lake graphics out-of-the-box. Now going along with that Linux 6.17+ support out-of-the-box, the Mesa OpenGL and Vulkan user-space drivers are also ready to declare their Xe3 Panther Lake graphics support by default.

One of the interesting new additions with the upcoming Intel Xe3 integrated and discrete graphics is the Variable Register Thread "VRT" feature. Making use of Variable Register Thread can reduce register splitting, reduce bandwidth consumption, and improve overall performance. More background information on Intel VRT can be found in that aforelinked Phoronix article. But now the ability is coming to optionally disable VRT.

Amid Intel's ongoing financial difficulties and multiple rounds of layoffs some Linux engineers at Intel left last year and there's been at least one prominent departure this week amid the latest round of challenges at the company.

Prior to the DG2/Alchemist discrete GPUs from Intel there was the DG1 graphics processor that served primarily as the initial developer vehicle for facilitating Intel's modern discrete GPU push. DG1 ended up being in the Intel Xe MAX GPU for a small number of laptops and then there's also been a select number of DG1 graphics cards surfacing on eBay in the years since. Only now in 2025 is the upstream Linux kernel driver set to enable Intel DG1 graphics out-of-the-box for modern Linux distributions.

While Q2 is drawing to an end in the coming hours, Intel software engineers this evening just released the Intel FFmpeg Cartwheel 2025Q1 update that provides all of their latest patches around Intel GPU/video acceleration for this widely-used, open-source multimedia library that have yet to be upstreamed into FFmpeg proper.

With the Linux 6.16 kernel Intel enabled the new Platform Temperature Control (PTC) interface as part of their int340x thermal driver. Now ahead of the Linux 6.17 kernel Intel PTC is being extended to support a Throttling Control Interface for those that may prefer running their system(s) hotter in order to enjoy better performance.
