The core perf subsystem updates have been merged for the in-development Linux 6.12 kernel.

Intel engineers today released OpenVINO 2024.4 as the newest version of their open-source AI toolkit. OpenVINO 2024.4 prepares for upcoming Intel Core Ultra Series 2 "Lunar Lake" processors, supports newer Gen AI models, now supports Python 3.12, and finally adds official support for Red Hat Enterprise Linux 9.

Intel Compute Runtime 24.35.30872.22 released today as the newest tagged version of this open-source GPU compute stack providing oneAPI Level Zero and OpenCL support for Linux and Windows systems.

Ahead of the Intel Core Ultra 200V "Lunar Lake" laptops beginning to ship starting next week, the Intel Linux NPU Driver 1.8 is now available as the latest software update for embracing the Intel NPU for AI offloading.

The Linux 6.11 kernel is expected to be christened as stable tomorrow. Ahead of that stable release one of the last minute "fixes" is adding in another ID for upcoming Intel Arrow Lake processors.

As written about early in the year, future Intel CPUs will be moving past the "Family 6" identification used since the mid-1990s with the P6 micro-architecture. Since then Intel has continued releasing new CPUs under "Family 6" with different model IDs while AMD has been more open to changing its Family ID every Zen generation or two. With Intel using Family 6 for so long it led to a lot of Linux kernel code just relying on Model ID comparisons for determining between Intel CPU generations and the like. Thus a lot of Intel CPU model handling reworks are needed for preparing future Intel CPU generations that will no longer be in Family 6. With Linux 6.12 it looks like that work will be wrapping up.

The Intel Graphics Compiler (IGC) that is used on Windows as a shader compiler back-end and both for Windows/Linux as part of their OpenCL and oneAPI Level Zero compute stack can now be compiled for RISC-V 64-bit.

With the upcoming PostgreSQL 17 database server release there is some initial AVX-512 optimizations that are looking quite nice according to Intel's findings.

Intel today as part of their "Patch Tuesday" released new CPU microcode for recent generation Core and Xeon processors. Two security updates were made along with fixing a handful of functional issues.

With the upcoming Linux 6.12 kernel the Intel graphics driver will finally be able to report GPU fan speeds. Another long sought feature is also on the way for this open-source Linux driver: GPU package temperature reporting for Intel discrete GPUs.

Intel today released a new version of QATlib, the QuickAssist Technology library for enjoying hardware-accelerated offloading of security, authentication, and compression needs. Recent Intel Xeon CPUs with built-in QAT accelerators stand to benefit a lot from the new QATlib 24.09 release.

Intel engineers have been working on enabling NPEM for Linux: Native PCIe Enclosure Management as a means of standardized storage LED indicators.

The Intel Arrow Lake Linux graphics driver support appears largely wrapped up following a patch for properly handling the necessary GSC firmware requirements and building off all the existing Meteor Lake Arc Graphics driver code paths. There are a number of Arrow Lake PCI device IDs already present for the graphics while a new one is being added now to the kernel drivers.

Last month I wrote about Intel Linux engineers working on a new Efficiency Latency Control feature for their uncore driver. This ELC option allows for adjusting the behavior of the Intel uncore for efficiency versus latency characteristics. Those Intel ELC patches to the TPMI uncore driver are now queued up for merging with the upcoming Linux 6.12 cycle.

While Intel Lunar Lake is only beginning to ship later this month, Intel Linux engineers have already begun work on enabling its successor: Panther Lake. With the upcoming Linux 6.12 kernel cycle will be more early enablement work on Intel Panther Lake, presumably what will be the Core Ultra 300 series.

The work written about earlier this year on New Intel Linux Patches Continue Working To Improve Hybrid CPU Task Placement looks like it will be merged for the upcoming Linux 6.12 cycle as the patches have now been queued into the power management subsystem's "-next" branch. This latest Intel Core hybrid handling work is particularly focused on hybrid P/E-core processors without SMT / Hyper Threading, such as found with the upcoming Core Ultra 200V "Lunar Lake" processors.

Intel has submitted more kernel graphics driver changes for the upcoming Linux 6.12 cycle. Following the pull requests to DRM-Next last week to enable Lunar Lake Xe2 graphics and Battlemage by default, some more lingering feature patches were merged today. Most exciting with this last round of patches before Linux 6.12? Intel graphics card fan speed reporting is finally wired up for their Linux driver.

With Linux 6.12 the Lunar Lake and Battlemage graphics are being enabled by default for out-of-the-box support with Intel's next-gen Xe2 graphics. Over in user-space the Intel OpenGL and Vulkan driver code has also begun enabling Xe2 graphics by default for use when running on Linux 6.12+. In Mesa besides no longer being hidden by the force probe option, a warning is now removed so users aren't told about unsupported Vulkan support when using Xe2 hardware.

Intel formally announced their Core Ultra 200V series "Lunar Lake" laptop processors today in Berlin.

Now that Linux 6.12 will enable Intel Battlemage and Lunar Lake graphics by default for the out-of-the-box kernel graphics driver support, the user-space Intel Mesa drivers with Iris Gallium3D (OpenGL) and ANV Vulkan are moving ahead to enable their support out-of-the-box too. This has been merged for Mesa 24.3-devel to have Battlemage discrete GPUs enjoying OpenGL and Vulkan support while it's also marked for back-porting to the Mesa 24.2 stable series.

Intel Compute Runtime 24.31.30508.7 was released this morning as the newest version of this OpenCL and oneAPI Level Zero compute stack used on both Windows and Linux platforms. Notable with the Intel Compute Runtime 24.31.30508.7 is having initial Xe2 support.

Intel has released a new version of their open-source Video Processing Library (VPL) for hardware-accelerated video encode / decode / processing across Intel graphics hardware.

Following the pull request from earlier this week that enables Intel Xe2 Lunar Lake and Battlemage graphics by default for Linux 6.12, a final set of feature updates for the Intel kernel graphics driver have been submitted ahead of this next kernel cycle.

While all of the focus recently when it comes to Intel's open-source Linux graphics driver has been around getting Lunar Lake and Battlemage graphics ready, there is an important last-minute fix that is also needed for ensuring Arrow Lake graphics support is ready for Linux users.

It's happening! The upcoming Linux 6.12 kernel cycle will be enabling the Xe2 graphics in Lunar Lake and Battlemage out-of-the-box / by-default. The Xe2 support within the open-source "Xe" kernel graphics driver appears to be stable enough now for enabling the support by default for Lunar Lake and Battlemage hardware with the next kernel version. The patches have been submitted.

With the Intel In-Memory Analytics Accelerator (IAA) and Data Streaming Accelerator (DSA) introduced first with Xeon Scalable "Sapphire Rapids" processors, they can be a big performance win for some workloads but can be a pain to setup and with limited software support. It also turns out that since a security advisory issued earlier in the year, current Intel IAA and DSA accelerators aren't safe for use within virtual machines (VMs) and that issue doesn't appear to be resolved until Diamond Rapids and Granite Rapids D processors.

Intel Linux graphics driver engineers continue to be very busy enabling the Xe Direct Rendering Manager that is becoming the default kernel graphics driver beginning with Xe2 Lunar Lake and Battlemage hardware (it currently works as an experimental option with existing Intel graphics hardware going back to Tigerlake). The latest work coming out of Intel is their latest push on enabling GPU Shared Virtual Memory (SVM) support.

Earlier this month Intel compiler engineers began adding AVX10.2 support into the GCC 15 open-source compiler. Now as we approach the end of August, another big batch of AVX10.2 enablement has landed for this next GNU Compiler Collection release.

Released on Sunday night was a new version of the Intel QuickAssist Technology (QAT) Zstd plug-in for accelerating Zstandard compression with QAT-enabled adapters and modern Xeon Scalable processors sporting QAT accelerators.

Intel's open-source Linux graphics driver engineers continue feverishly working on the Xe2 graphics support both for imminently-launching Lunar Lake laptops and then the Battlemage discrete graphics cards. This week more "missing bits" were addressed in new Intel Linux graphics driver code on its way to DRM-Next ahead of the upcoming Linux 6.12 merge window.

Intel software engineers are responsible for many of the great x86_64-related optimizations to the GNU C Library "glibc" over the years. While they've extensively tuned many Glibc functions for achieving peak performance on their modern CPUs, it's a never-ending quest. Merged this week was another optimization to strnlen(), the function for determining the number of bytes in a fixed-size string.

Intel's uncore Linux platform driver is preparing for a new feature found on newer SoCs: ELC, or Efficiency Latency Control. This ELC feature for the Intel uncore handling allows fine tuning efficiency versus latency characteristics.

As part of Intel's Scalable Video Technology (SVT) initiative they had been developing SVT-HEVC as a BSD-licensed high performance H.265/HEVC video encoder optimized for Xeon Scalable and Xeon D processors. But recently they've changed course and the project has been officially discontinued.

Intel engineers on Wednesday released the Linux NPU Driver v1.6 release for this for this MIT-licensed user-space mode driver support for the Neural Processing Unit (NPU) found since the Core Ultra Series 1 "Meteor Lake" SoCs and currently supporting the upcoming Lunar Lake and Arrow Lake processors as well. This Intel Linux NPU Driver in user-space interfaces with their iVPU kernel accelerator driver for making a nice open-source and upstream NPU software stack on Linux systems.

Intel published a number of new CPU microcode images this Patch Tuesday for addressing various security issues as well as a number of functional issues being addressed across different CPU client and server processor generations.

Intel Linux graphics driver engineers today sent in their first batch of patches to DRM-Next of new material they are prepared to introduce with the upcoming Linux 6.12 kernel cycle.

Last week I wrote about a tiny Linux patch yielding up to 32% faster performance and up to 18% less energy for Emerald Rapids CPUs. That patch is an adjustment to the Intel P-State driver's Energy Performance Preference (EPP) value for that Intel Xeon Scalable family. Today that patch was merged for the Linux 6.11 kernel.

With upcoming Intel Arrow Lake H processors it's just not P cores and E cores but for the E cores will be a mix of both Skymont and Crestmont core types.

A seemingly late patch for the Intel Idle (intel_idle) Linux kernel driver enables support for upcoming Xeon 6 Granite Rapids processors.

Building off some "request for comments" patches sent out in April, a new set of patches appeared on Friday for the Intel P-State Linux driver for setting the asymmetric CPU capacity on hybrid systems. This is another attempt at helping to improve the Linux kernel scheduler behavior in ensuring optimal task placement between Intel Core processors having a mix of P and E cores. This patch series in particular helps when SMT / Hyper Threading support is disabled or like with upcoming Lunar Lake processors where there is no HT support.

A one line patch to the Linux kernel is yielding significant performance and power efficiency gains for existing Intel Xeon "Emerald Rapids" server processors on the likes of Ubuntu Linux.

The open-source Intel "ANV" Vulkan driver within Mesa is now more capable for its Vulkan Video support with the H.264 and H.265 encode support now wired up for Mesa 24.3.

Intel closed out July by publishing AVX10.2 technical details as part of a now public document. Intel's compiler engineers are also already at work on enabling AVX10.2 in the GCC and LLVM/Clang compilers.

While the Linux 6.11 merge window ended just days ago, Intel engineers are already beginning to submit kernel graphics driver changes to the DRM-Next branch of material they want to get in for the Linux 6.12 cycle that will end out 2024. Notable is they are trying to wrap up the Xe2 graphics support for Lunar Lake and Battlemage discrete graphics so that the support can be exposed by default.

Last year the oneAPI Construction Kit was introduced by Intel-owned Codeplay Software for bringing SYCL to new hardware even for hardware outside of Intel's offerings. One of the early targets of this oneAPI Construction Kit support was for RISC-V processors and now with today's release of oneAPI Construction Kit 4.0 there is finally RISC-V host CPU support.

With the AMD Ryzen AI 300 "Strix Point" laptops now shipping this week, Intel has announced that their Intel Core Ultra "Lunar Lake" processors as the successor to Meteor Lake will be formally launching on 3 September.

It was just two months ago that Oded Gabbay, the longtime maintainer of the Habana Labs kernel accelerator driver for Linux, announced he was stepping down from his software role and leaving Intel. Oded Gabbay was also a maintainer of the new Intel Xe kernel graphics driver. That was a surprising move with Oded Gabbay having been at Intel / Habana Labs for 7+ years and oversaw the creation of the Linux kernel's "accel" accelerator subsystem and more while prior to that having been at Red Hat and AMD. Ofir Bitton was named the Habana Labs driver maintainer following that but now he announced he too is leaving Intel.

Intel is kicking off the new week with a new release to their open-source Compute Runtime stack that provides OpenCL and Level Zero support across Windows and Linux systems with Intel integrated/discrete graphics.

The open-source software pieces have come together where Fedora / Red Hat developers are hoping that for Fedora 41 there can be out-of-the-box support for the web cameras on newer Intel laptops.

Intel today released IGC 1.0.17193.4 as the newest version of the Intel Graphics Compiler that is used for their compute stack on Windows/Linux as well as by their Windows graphics driver for shader compilation.
