Intel's compiler experts in Moscow have been working on OpenCL C 3.0 support for the LLVM Clang compiler front-end.

Patches sent out on Friday provide an initial DP-HDMI2.1 PCON implementation for the Intel Linux kernel graphics driver.

Intel continues bringing up the DG1 discrete graphics card under Linux with continued refinements set to hit for Linux 5.10.

Last month Intel published a whitepaper on TDX as Trust Domain Extensions as a means of better securing virtual machines. TDX allows for isolating VMs from the hypervisor and other non-VMM system software. Intel TDX builds off other recent work around MKTME memory encryption and other features. We are now beginning to see that software side support roll-out along with the also-new Key Locker instructions.

As first outlined earlier this year, Intel has been working on the Linux support for Platform Monitoring Technology as a new hardware telemetry feature first introduced with new Tigerlake hardware. It's looking like the initial Intel PMT support will come with Linux 5.10 while further work is being prepared that builds off its foundation.

It's still not clear when Intel SGX support will be accepted for the mainline Linux kernel.

The Cloud-Hypervisor project that is led by Intel open-source folks for providing a cloud-focused hypervisor written in the Rust programming language is out with a new feature release.

Intel's software team has released a new version of their Compute Runtime that provides OpenCL and oneAPI Level Zero capabilities for their graphics hardware on Linux.

Building off their earlier Intel graphics driver pull request of new material queuing ahead of the Linux 5.10 cycle, another round of updates were submitted on Friday.

Intel has debuted a new version of HAXM, its Hardware-Accelerated Execution Manager that serves as an accelerator for the Android Emulator and QEMU via Intel VT enabled CPUs.

The feature to provide opt-in flushing of the L1 data cache on each context switch looks like it will be coming with the Linux 5.10 cycle for this functionality providing security benefits but at the cost of further performance degradation.

The Intel Graphics Compiler (IGC) that is used by their Linux OpenCL/Level-Zero compute stack as well as now being used by their Windows graphics driver and potentially their Linux OpenGL/Vulkan drivers in the future is out with a new release.

One of the interesting Intel Linux graphics driver patches to be sent out last year were for per-client engine reporting to allow on a per-application/process basis to see how the GPU's render/blitter/video engines were being utilized.

Intel-owned AI startup Habana Labs is working on expanding their "Gaudi" support to now include the NIC network interface found on this AI training accelerator hardware.

The latest Intel oneAPI software release is a new monthly update to their LLVM-based oneAPI Data Parallel C++ (DPC++) compiler.

With Intel Xe LP / Tigerlake adding AV1 accelerated video decode, the Intel open-source developers are working to expose their AV1 hardware acceleration through the Video Acceleration API (VA-API) for usage by the likes of FFmpeg and other multimedia software.

Proposed last year were a set of patches aiming to improve the Intel virtual GPU "vGPU" performance in para-virtualized cases by having optimizations around the shared memory region between the guest and Intel GVTg code. With optimizing the workload PV submission and PPGTT PV updates, the glxgears performance could improve by 30~50% while for large media/3D workloads was more around a 4% average improvement.

Intel's September 2020 security advisories were posted today and include four security advisories around nine vulnerabilities.

With Intel Gen11 graphics and newer supporting Adaptive-Sync / Variable Refresh Rate for minimizing tearing and stuttering, their open-source developers have now added the necessary bits to the generic xf86-video-modesetting X.Org driver for supporting the VRR functionality.

Intel's open-source SVT-AV1 encoder that is now being used as the basis for the AV1 Software Working Group and used by Netflix and other organizations for being one of the most performant CPU-based AV1 encoders is out with a new release.

Patches were posted on Friday for introducing the Intel Security Manager class driver to the Linux kernel.

Intel's iNet Wireless Daemon (IWD) is out with a new feature release with this daemon continuing to see new usage and possibly on Ubuntu moving forward.

In addition to Intel talking a lot today in virtual briefings about the new 11th Gen "Tiger Lake" mobile processors, they were also talking at a higher level extensively on their second-generation "Project Athena" laptop innovation program and their new Intel Evo branding for premium laptops.

Intel's open-source engineers today sent out their latest patches bringing up the Dynamic Load Balancer 2.0 for the next-gen PCIe device that offers load-balanced, prioritized scheduling of core-to-core communication.

Going back to earlier this year has been work on an "adaptive" mode for P-State to improve GPU bound efficiency when the CPU is forced to share a power/thermal budget with other components like onboard graphics. That work is still advancing and an update was provided on it last week.

While the Linux 5.9 kernel cycle is still young and not seeing its formal release until early October or so, Intel's open-source team has already submitted to DRM-Next their first batch of feature changes desired for Linux 5.10.

As part of the virtual SIGGRAPH20, Intel is using the opportunity to talk up their ray-tracing efforts.

Along with this week marking the release of oneAPI Level Zero 1.0, the oneAPI Data Parallel C++ compiler has seen its newest tagged release.

As part of the upcoming oneAPI 1.0 "Gold" release, oneAPI Level Zero 1.0 was released this morning.

With Intel's Lakefield and the future Alder Lake with their hybrid x86 architecture mixing of "little" and "big" cores, operating system optimizations become all the more important and thus will be interesting to see how the battle is between Windows and Linux.
