While Intel is the company behind XeSS - Xe Super Sampling, under Linux it's an ongoing story of having to hide the fact that Intel graphics are in use when trying to enjoy Windows games running on Steam Play that are XeSS-enabled. The latest example is the HITMAN 3 game that can work on modern Arc Graphics as long as you conceal the fact under Linux that Intel graphics are being used.

Intel's Iris Gallium3D driver for providing open-source OpenGL support on Linux systems has implemented indirect draw generation. For software relying heavily on indirect draws will see a "massive boost" in performance.

It's been nearly one year to the day since outlining intel's AVX-512 powered sorting library to offer blazing fast sort speeds. Over the past year has brought the 1.0 release, new algorithms in v2.0, AVX2 support and more AVX-512 optimizations in v4.0, and now today Intel is out with x86-simd-sort 5.0 with yet more performance improvements.

Webcamera support on recent generations of Intel laptops have tended to be a mess due to the Intel IPU6 requiring an out-of-tree kernel driver and a proprietary user-space component. But fortunately thanks to the work of Linar and Red Hat on a "SoftISP" implementation within libcamera, it's becoming possible to leverage these recent MIPI-based webcameras on an open-source software stack.

Along with the recently merged Intel OpenGL and Vulkan driver support for Arrow Lake next-generation Core processors with Mesa 24.1, it looks like the i915 kernel graphics driver support for Arrow Lake will be all-set with the upcoming Linux 6.9 kernel cycle.

Intel Arrow Lake platform support has been merged to Mesa 24.1 for providing the ANV Vulkan and Iris Gallium3D (OpenGL) open-source drivers with support for the next-generation Intel Core integrated graphics.

Ahead of any processors being released with support for Advanced Performance Extensions (APX) and Advanced Vector Extensions 10 (AVX10), Intel's in-house Clear Linux distribution is already beginning to roll-out binaries compiled for APX+AVX10 use.

Intel's hybrid core handling for modern Intel Core CPUs with a mix of P and E cores has largely been in good shape under Linux for a while. Intel Thread Director support has come along with various Linux kernel improvements to better handle task placement between the P and E cores. One area seeing new work now though is for virtual machines (VMs) running on Intel hybrid systems with a new Linux kernel patch series working on Thread Director Virtualization.

Intel's open-source oneAPI components continue to not only embrace Intel's diverse range of CPUs / GPUs / accelerators but continues to better support competing platforms too. Today's Open Image Denoise release candidate brings more for Apple hardware, AArch64 processors, and NVIDIA CUDA.

Webcameras on newer Intel laptops have been challenging for Linux use without resorting to an out-of-tree driver and proprietary user-space components, but that's been thankfully changing with progress being made on an open-source stack. There's still proprietary firmware necessary for enabling the IPU6 image processing unit, but at least that too is now in linux-firmware.git for easy distribution and packaging by Linux distributions.

While Intel typically does a great job with their open-source Linux hardware support with enabling all features under Linux and doing so in a timely manner -- often well in advance of the client and server hardware availability -- an exception in recent years has been around the web cam support for many newer Intel laptops. Since Alder Lake an increasing number of Intel-powered laptops have been relying on a raw MIPI camera sensor connected to the IPU6 IP. Intel has been tightly controlling the intellectual property around IPU6 so in turn their Linux support has consisted of an out-of-tree kernel driver and a proprietary user-space component. But thanks to Linaro and Red Hat, an open-source alternative has been forming.

For the better part of two years we've seen Intel open-source software engineers working on preparing the Linux kernel for FRED, the Flexible Return and Event Delivery for defining new transitions for changing privilege levels. Intel's been working hard on the FRED kernel plumbing for better performance, lower response times, and improved robustness and it's looking like FRED could be set to land come Linux 6.9.

Intel engineers on Wednesday released OpenVINO 2023.3 as the latest major update to this leading open-source AI toolkit. The OpenVINO 2023.3 brings "full support" for new Emerald Rapids and Meteor Lake processors, other Intel hardware support improvements, and continuing to expand support around generative AI (GenAI) and large language models (LLMs).

While AMD's GPUOpen team developed the Radeon Memory Visualizer for their own Radeon graphics processors, thanks to the software working out well and being open-source and the profiling/dump format being public, the Intel open-source Vulkan Linux driver has added support for it. With the Intel ANV Mesa driver you can now generate Radeon Memory Visualizer (RMV) compatible dumps that can then be loaded into the GPUOpen software for analyzing the video memory behavior of Intel's integrated and discrete graphics.

While Intel's Sierra Forest as their first all-E-core Xeon processor with up to 288 cores per socket isn't launching until around the middle of this calendar year, Intel Linux engineers already sent out their first kernel patch in beginning to target its successor: Clearwater Forest.

When it comes to the Linux kernel's "crypto" subsystem for various cryptographic and compression algorithms and various hardware drivers, the new additions for Linux 6.8 are particularly interesting on the Intel side.

Linux 6.7 introduced the "ia32_emulation=" boot option for enabling/disabling support for x86 32-bit programs and the ability to execute 32-bit system calls. This is part of the effort of some Linux distributions working to restrict x86 32-bit user-space support where not needed in order to reduce the software attack surface while still having a boot-time option for those wanting to enable 32-bit support or to otherwise disable it if your kernel build keeps it enabled.

Following last week's Linux 6.8 power management updates, Linux PM/ACPI subsystem maintainer Rafael Wysocki of Intel sent out a secondary set of changes this morning. Most notable with this second round of power management material is allowing Intel Core Ultra "Meteor Lake" processors to clock higher with the P-State CPU frequency scaling driver.

Intel engineer Dan Williams continues leading the charge around Compute Express Link (CXL) enablement for the Linux kernel.

Intel has prepared additional Trust Domain Extensions enablement code for the ongoing Linux 6.8 kernel merge window.

Intel Compute Runtime 23.39.27427.23 has been released today as the newest version of this open-source GPU compute stack for Windows and Linux systems for OpenCL and oneAPI Level Zero support. The Compute Runtime works from aging Broadwell and Skylake/Gen9 graphics up through the latest DG2 discrete graphics and the recently launched Meteor Lake processors with their much improved integrated graphics.

Intel engineers have released their FFmpeg Cartwheel 2023Q4 release, the quarterly set of updates to the FFmpeg multimedia library that they are still working to get upstreamed where appropriate but for now is a convenient home to all of their interesting FFmpeg patches from improved video acceleration for Intel graphics hardware to neural network features still being developed and other patches that aren't yet ready for inclusion into upstream FFmpeg.

Following various leaks / rumors / teases in recent days, MSI today formally unveiled the Claw A1M as their first handheld gaming device and the first handheld gaming console in recent time to use an Intel SoC.

The Intel engineers enabling next-generation Arrow Lake processors for Linux have largely been just adding new device IDs and other mostly minor changes over current Meteor Lake processors. It was that way too for Arrow Lake's integrated graphics with largely re-using existing Meteor Lake graphics support, but now it's come to light that select Arrow Lake SKUs will feature updated graphics IP.

The upcoming Linux 6.8 kernel cycle will introduce support for Intel's Linear Address Masking (LAM) for use within KVM virtualized guests.

The Intel frame-buffer driver "IntelFB" has been solicited for removal from the mainline Linux kernel. This FBDEV driver is for supporting very old Intel i8xx/i9xx integrated graphics hardware.

Intel along with investment firm DigitalBridge Group announced the formation today of Articul8, an independent company to focus on turn-key Generative AI "GenAI" for enterprise customers and focused on enterprise workflows.

Overnight Intel released their newest quarterly updates to their Intel Media Driver providing Video Acceleration API (VA-API) support on Linux systems as well as their updated oneVPL video processing library that is part of their oneAPI software stack and leveraging the Intel Media Driver.

Queued in the kernel's crypto subsystem development tree ahead of the upcoming Linux 6.8 merge window is introducing support for next-gen Intel QAT accelerators. The Intel QAT 420xx devices will support more acceleration engines as well as additional algorithms for next-generation QuickAssist Technology.

After looking earlier today at the most viewed AMD Linux/open-source stories of 2023, here's a look at the other side of the table with the most popular Intel content on Phoronix for the past year with my daily open-source and Linux focused coverage.

Added last year to the open-source compilers were Intel RAO-INT instructions for upcoming Intel CPUs. RAO-INT as new atomic ADD / AND / OR / XOR instructions were to debut with Intel's Grand Ridge SoC but now that is apparently no longer the case.

Merged on Friday for Mesa 24.0-devel in Q1 is support for the VK_KHR_cooperative_matrix extension with Intel's "ANV" Vulkan Linux driver.

With Linux 6.8 set to introduce the new Intel Xe experimental kernel graphics driver early next year, last week I ran some Xe vs. i915 driver benchmarks on various Intel Arc Graphics discrete GPUs. There's still room for bettering the performance but a nice initial entry into the kernel and easy to test out. For some Christmas weekend benchmarking I was curious to see how well the Xe kernel driver would work on the integrated graphics side with the new Meteor Lake processors.

Along with all of the other ongoing Intel Arrow Lake processor/platform enablement, the upcoming Linux 6.8 kernel will have the sound driver support ready for landing.

Intel's open-source Linux drivers for OpenGL (Iris) and Vulkan (ANV) this week for Mesa 24.0 received support for dual-SIMD8 dispatch on Gen12 graphics (Tigerlake) and newer.

In helping to guide Intel's open-source interests in 2024, the company is hosting an Open-Source Community Survey. Intel is looking for feedback from open-source developers and other community stakeholders about your principal interests and concerns.

The latest bits of future Intel CPU hardware support being queued for the mainline kernel is adding Intel Idle driver support for the upcoming Sierra Forest and Grand Ridge processors.

For those with Intel Arc Graphics on Linux and wanting to enjoy the game Baldur's Gate 3 thanks to the power of Valve's Steam Play software, an important fix has been merged to Mesa 24.0-devel and set for back-porting to Mesa 23.3. This should take care of rendering issues being reported for Baldur's Gate 3 with Intel graphics on Linux when using the Vulkan renderer.

Back in January I wrote about Intel working on a Timed I/O driver for Linux with PPS (Pulse Per Second) to help with time synchronization between multiple devices. There hasn't been much external talk about this Timed I/O / PPS functionality while today as we approach the end of the year a new set of Linux kernel patches were posted for wiring up this Intel PPS Generator functionality.

Intel's new Xe kernel graphics driver is set for merging into Linux 6.8 as an experimental option. While it's being added to the next kernel cycle, it's not yet used by default for any existing Intel GPUs and its features have yet to be fully implemented and the performance has yet to be fully optimized. Among the features currently missing is Shared Virtual Memory (SVM) support but a patch series posted today aims to address that functionality.

With AI being all the rage these days and each vendor working on getting their wares to market with AI acceleration, besides Intel now having out their Meteor Lake CPUs that feature their Intel AI Boost (NPU), Intel is rather positioned well with their prolific open-source software contributions. One of the AI-related software contributions over the past week has been improvements to the FFmpeg multimedia library's "DNN detect" filter for object detection within videos.

Set to be merged for the upcoming Linux 6.8 kernel cycle is the IAA crypto compression driver for allowing users of the Linux kernel's compression API to make use of the Intel Analytics Accelerator (IAA) found with Sapphire Rapids and Emerald Rapids Xeon server processors.

By now you've likely heard how Intel's Gaudi2 accelerator hardware is standing up very well against the NVIDIA competition especially in value. There's nothing new there but an important part to keep in mind -- and where Intel is the hands-down winner -- is the open-source ecosystem with having a fully open-source and upstream Linux kernel accelerator driver as well as their SynapseAI open-source components in user-space. The Gaudi2 open-source kernel driver support is now considered "very stable at this point" with the upstream state fairing well.

While Intel Meteor Lake processors only launched last week, Intel Linux engineers have already been busy for some time enabling next-generation Arrow Lake and Lunar Lake processors.

As I wrote about last week that Intel's modern Xe kernel graphics driver was nearing submission for the mainline kernel and today it's indeed been submitted to DRM-Next. The Intel Xe kernel graphics driver is the modern alternative to the long-used i915 DRM kernel driver and is fitted to support Tigerlake graphics and newer -- both integrated graphics hardware as well as discrete GPUs/accelerators.

Intel's VC Intrinsics software package that provides a set of intrinsics atop the LLVM IR instructions to represent SIMD semantics for programs targeting Intel GPUs has been updated for new hardware support.

While some at Intel were busy launching the 5th Gen Xeon Scalable "Emerald Rapids", other Linux engineers at the company were pushing ahead on their new hardware enablement quest for future platforms. Sent out on the same day as Emerald Rapids being announced were continued patches for enabling Grand Ridge.

While Intel's AI Everywhere event today was primarily focused on Core Ultra "Meteor Lake" laptop processors and 5th Gen Xeon Scalable "Emerald Rapids" processors, Intel also briefly announced their newest Xeon D and Xeon E series processors.

With Intel's very timely upstream Linux hardware support going back years, they typically start on the upstream hardware enablement well in advance of the product's planned public launch. On a number of occasions this has meant adding support to the Linux kernel for hardware that never ends up being released to consumers. There's been recent cases like the Thunder Bay support that was dropped from the kernel after it became clear that the SoC would never ship to now a more extreme case of a driver being in the mainline kernel for 15 years to support never-released hardware.

Linux 6.6 brought an initial Intel Visual Sensing Controller "IVSC" driver. The Intel IVSC drivers have long been out-of-tree for use with Alder Lake laptops and newer. Linux 6.7 brought the La Jolla Cove Adadpter driver code as part of the IVSC controller. With Linux 6.8 there's yet more work landing on the IVSC front.
