Intel Linux Driver Adds New DG2 "G12" Graphics Variant

To date the Intel Linux graphics driver has supported Intel's DG2 "Alchemist" G10 and G11 sub-platforms/variants as the main designs to this point. However, at the end of last year we began seeing "G12" references surface in their compute stack and now the Intel open-source Linux kernel driver is formally preparing the DG2-G12 variant support.

Intel's Unaccepted Memory Support Updated For Substantially Faster Booting Of TDX VMs

Way back in August Intel posted a set of Linux kernel patches for supporting "unaccepted memory" by the Linux kernel in preparation for next-generation Xeon processors and speeding up the boot time for guest virtual machines making use of Intel's Trust Domain Extensions (TDX) security feature. Unaccepted memory support hasn't yet made it to the mainline kernel but now a second iteration of the patches have been posted.

Intel ISPC 1.17 Compiler Released With Xe HPG, PS5 & AMD Zen Support

Intel ended out the week with a huge update to ISPC, the Intel Implicit SPMD Program Compiler. ISPC is Intel's LLVM-based compiler focused on its C variant with extensions for single program, multiple data (SPMD) programming. Interestingly with this release is the introduction of AMD Zen 1/2/3 targeting and even the PlayStation 5 while also adding support for forthcoming Intel Arc "Alchemist" (Xe HPG) hardware.

Intel's Linux Graphics Driver Continues With Multi-Tile Preparations

In addition to Intel's open-source Linux graphics driver developers being quite busy preparing for upcoming Intel Arc "Alchemist" (DG2) graphics cards on the consumer side, they have concurrently been preparing for Xe HP "Ponte Vecchio" hardware too. One of the big undertakings on that side from the driver perspective is bringing up multiple tiles.

Intel AMX Support For KVM Use May Be Ready For Mainline

In preparation for Xeon Scalable "Sapphire Rapids" processors, Linux 5.16 adds support for Advanced Matrix Extensions. But that AMX bring-up is more invasive than when introducing AVX as with AMX the feature needs to be "requested" for use by user-space, among other changes. As such extra handling also needed to be introduced for the Kernel-based Virtual Machine (KVM) that hadn't made it for v5.16 but now it looks like the AMX KVM support may be ready for mainline.

Mesa 22.0 Intel OpenGL/Vulkan Drivers Enable Adaptive-Sync/VRR

In the mainline Linux kernel for a year now has been the Intel variable rate refresh (VRR) support for Gen12 / Xe Graphics and then with the upcoming Linux 5.17 cycle that's being enabled for Gen11 Ice Lake graphics too. With the Intel i915 DRM kernel driver support for VRR/Adaptive-Sync being mature, the Intel Mesa OpenGL and Vulkan driver components are finally enabling the support by default.

Intel HFI Code Revised For Improving Alder Lake's Hybrid Support On Linux

Back in late 2020 Intel's programming manuals detailed the Enhanced Hardware Feedback Interface for the CPU to provide guidance to the kernel's scheduler on optimal task placement of workloads. While marketed as Thread Director with the new 12th Gen Alder Lake processors, that hardware feedback interface support is getting squared away for the Linux kernel to improve the support for these newest processors.

Recapping Intel's Open-Source/Linux Achievements For 2021

It was another exciting year for Intel on the open-source/Linux front with countless contributions to the Linux kernel, Mesa, and other open-source projects. Intel's oneAPI toolkits continue humming along and they continue maintaining tons of other projects from Clear Linux to SVT-AV1 to IWD and many more. Intel's Linux graphics driver developers have also been extremely busy preparing the open-source support for next year's discrete GPU launches. Here is a look at the most popular Intel articles on Phoronix during the course of 2021.

Sound Open Firmware 2.0 Released For The Intel-Led Open-Source DSP Stack

It was nearly four years ago already that Intel announced Sound Open Firmware in pushing for open-source sound firmware for their hardware. The Sound Open Firmware effort has been a great success even if it's not a shiny project widely talked about among consumers. Just prior to the holidays Sound Open Firmware 2.0 was quietly released.

Intel Prepares To Re-Enable ENQCMD On Linux After Being Disabled For "Broken Beyond Repair"

The ENQCMD functionality that is part of Intel's Data Streaming Accelerator with upcoming Xeon Scalable "Sapphire Rapids" processors was disabled earlier this year for being "broken beyond repair". But now ahead of Sapphire Rapids beginning to ramp up in the coming months, Intel open-source engineers believe they have improved the code that the ENQCMD instruction usage could be re-enabled for the Linux kernel.
