Mesa 21.2 Begins Seeing Intel Xe-HP Graphics Driver Changes

With Mesa 21.1 now branched for this collection of primarily OpenGL/Vulkan open-source drivers for Linux, feature development is on for Mesa 21.2 that will debut in Q3. One of the first major changes to land for Mesa 21.2 is the beginning of the graphics compiler support for Intel's forthcoming Xe-HP high performance graphics processor.

Patches Resubmitted For Linux With Selectable Intel Graphics Platform Support

Back in early 2018 were patches proposed for selectable platform support when building Intel's kernel graphics driver so users/distributions if desired could disable extremely old hardware support and/or cater kernel builds for specific Intel graphics generations. Three years later those patches have been re-proposed.

Intel DG1 Graphics Card Nears Working State On Linux

While these kernel patches aren't expected to land until the Linux 5.14 kernel cycle later in the summer, a set of 19 patches published on Monday morning begin allowing a test system to boot with the DG1 graphics card.

Intel Rocket Lake Target Added To GCC 11

While Intel is often very proactive in adding new CPU families to the open-source GCC and LLVM/Clang compilers where it tends to land a year or more in advance of the processors actually shipping, occasionally there are slipups. Today in fact the "Rocket Lake" support finally was merged into GCC 11 days ahead of that compiler release and after the CPUs were already launched at the end of March.

GCC 11 Lands A Last Minute Optimization For Intel Skylake

While Skylake was introduced a half-decade ago already, Intel's open-source engineers aren't done relentlessly optimizing for it and subsequent 14nm processors. Hitting the GCC 11 open-source compiler today was an optimization for benefiting Skylake through the likes of Cascade Lake with some possible performance benefits.

The Current State Of The Intel "Crocus" Gallium3D Driver

The Intel "Crocus" Gallium3D driver in development for supporting old Intel i965 IGPs through Haswell continues making progress by the upstream, open-source Mesa3D community for hopefully one day replacing Intel's classic "i965" Mesa driver.

Intel Graphics Compiler 1.0.6748 Released With CM-CL Library

Intel's open-source developers have released a new version of IGC, the Intel Graphics Compiler that is used by their open-source Linux compute stack, recently was transitioned for use by their Windows driver too, and might eventually be piped into their Mesa OpenGL/Vulkan drivers.

More Intel Core i5 11600K, Core i9 11900K Benchmarks

Along with our Intel Core i5 11600K + Core i9 11900K Linux review from yesterday with 22 pages of benchmarks, even more performance data is now published and continues to flow in via OpenBenchmarking.org for looking at the Intel Rocket Lake performance across hundreds of benchmarks and compared to many other processors we have tested and that of the community.

Intel's Bus Lock Detection Might Be Ready For The Mainline Linux Kernel

For longer than the past year Intel engineers have been working on wiring up the Linux kernel support to handle split lock detection and bus lock detection. Back in Linux 5.7 the split lock detection landed for warning or even killing the offending software should a split lock occur due to the significant performance impact and possible denial of service. Now it's looking like the bus lock detection code could be ready for mainline.

Intel GNA Linux Driver Updated For Accelerating Speech Recognition, Noise Reduction

While Intel is well known and loved for their generally very timely open-source hardware enablement under Linux, occasionally there are exceptions to that long-standing tradition of having the support squared away ahead of product launches. One of the areas where Intel has been slow at enabling their open-source Linux support is around their Gaussian and Neural Accelerator (GNA) but that driver is now coming together for being mainlined hopefully in the near future.

Crocus: Working On Gallium3D For Old Intel Graphics

Raised during the recent discussion over looking at removing Mesa's classic drivers from the mainline tree this year is that there still exists an effort trying to create an Intel Gallium3D driver for older pre-Broadwell graphics currently only served by the i965 classic driver. That Crocus effort continues to be worked on but isn't yet mainline.

Intel Tweaking Ice Lake Xeon Linux Power Management Code For Higher C6 Latency

While Intel upstreamed their forthcoming "Ice Lake" Xeon processor support long ago and has been focused on next-gen Sapphire Rapids enablement now for the better part of the past year, there still are some Ice Lake Xeon tweaks taking place here and there. This week a new bleeding-edge patch is in testing for tweaking the power/performance behavior of Ice Lake Xeon with Intel's idle driver.

Intel Alder Lake P Media Driver Support Published

This week marked Intel sending out initial Linux driver enablement patches for Alder Lake P mobile support to complement the existing Alder Lake S desktop support that has been coming together in recent months. In addition to the Linux kernel code for ADL-P, the Intel open-source Media Driver code was also updated for video acceleration on this Intel hybrid chip.

Intel Sends Out New Linux Driver Patches For "XE_LPD" v13 Display Hardware

Intel sent out their latest open-source Linux driver patches today for their new "XE_LPD" display architecture that will be found with upcoming hardware platforms. XE_LPD features "version 13" display capabilities but not to be confused with "Gen13" graphics as they are beginning to more segregate their different Intel GPU IP blocks.

Intel's Lightning Mountain Appears Punted Off Or Canned As Part Of MaxLinear Acquisition

Back in 2019 we reported on Intel bringing up a new SoC dubbed "Lighting Mountain" to be used as a network processor and for other use-cases. Intel brought up that initial Linux kernel code for Lightning Mountain in 2019 but since then the code has already begun to fall into disrepair while it looks like it was either punted off as part of MaxLinear's acquisition last year of the Intel Home Gateway Platform Division or otherwise as a result of that was cancelled.

Researchers Discover Intel CPU Ring Interconnects Vulnerable To Side Channel Attack

University of Illinois researchers have discovered that Intel's CPU ring interconnects are vulnerable to exploit by side-channel attacks. This opens a whole new can of worms with the cross-core interconnect now being vulnerable to exploit but so far Intel doesn't appear to be overly concerned and there are some open questions on whether this interconnect exploit would still work with the latest Intel Xeon processors.
