  • Intel Adds VA-API Acceleration For HEVC REXT To FFmpeg

    Intel open-source developers have contributed support for VA-API acceleration of HEVC REXT "Range Extensions" content with the widely-used FFmpeg library.

    HEVC Range Extensions are extensions to H.265 geared for areas of content distribution, medical imaging, still imaging, and more. Among the changes with HEVC REXT are supporting 4:2:2 and 4:4:4 chroma sampling formats. HEVC Range Extensions are laid out in much more detail in this IEEE.org paper.

  • Intel Boosts Gen7 GPU Vulkan Compute Performance By ~330% For Geekbench

    Intel's open-source "ANV" Vulkan driver for Linux doesn't see much attention for pre-Broadwell hardware but today it saw a big improvement for Vulkan compute on aging Gen7 Ivybridge/Haswell era hardware.

    Jason Ekstrand, the lead developer of the Intel ANV Vulkan driver, discovered that in their driver's pipeline code the data cache functionality would end up being disabled when a shader was pulled out of the pipeline cache. For Broadwell/Gen8+ the data cache bit was being ignored but this oversight ended up having huge implications for Gen7 Intel graphics hardware (Ivybridge/Haswell) as the oldest supported by Intel's Vulkan driver.

  • Intel Has Accumulated 400+ Graphics Driver Patches So Far For Linux 5.7

    Intel just sent out their initial pull request of new feature changes/improvements to DRM-Next that in turn is for landing in about one month's time when the Linux 5.7 merge window kicks off. With taking longer than usual to send in their first round of feature updates, this first of several pull requests already amounts to over 400 patches.

    While it is a big pull request given the extra time for patches to accumulate, there aren't too many user-facing changes. Though there is a lot of enablement work for Tiger Lake as well as continuing Gen11 Ice Lake and Elkhart Lake work. For Ice Lake / Elkhart Lake there are a number of driver workarounds added. For Gen12 / Tiger Lake there are workarounds, display fixes, RPS is re-enabled, and other work.

  • Intel KVM Virtualization Hit By Vulnerability Over Unfinished Code

    At least not another hardware vulnerability, but CVE-2020-2732 appears to stem from unfinished code within the Intel VMX code for the Linux kernel's Kernel-based Virtual Machine (KVM) support.

    CVE-2020-2732 as of writing isn't yet public but we've been closely monitoring it since seeing a peculiar patch series earlier today and not finding much information on it.

Red Hat Fluff and News

  • Q&A: How open source made Kubernetes appealing to enterprise app developers

    A: We are at an interesting inflection point right now with computing. We went from physical hardware to virtual machines to containers and to concepts like serverless computing. And we’re asking questions like, “Can it get even smaller?” We’re trying to make the underlying platform more powerful, but less and less visible. So if it’s invisible to developers, do we just stop caring about it? But you could make the same argument with Linux, right? If the application is done well, and Linux is doing its job, you shouldn't care about it. It's just running, it’s fast, it’s scalable. Kubernetes probably follows that path more than anything.

  • Inside Red Hat: Its open source heritage means big opportunity in cloud computing

    The open source proposition has been embedded in Red Hat’s roots since the company’s founding in 1993 and has since remained at the core of its guiding principles, with Linux operating system (OS) at the heart of all its innovations. Vendor loyalty and clearly charted paths were the mantras many companies operated on for years, while “digital transformation” was barely on an enterprise’s short-term road map. Then a decade ago, cloud adoption surged, creating the impetus to embrace more agile and flexible development models, and open source technologies emerged. [...] While the topic of COVID-19 did not overtly dominate the discussions or significantly color the overarching Red Hat messaging, it became clear that the ability to pivot rapidly, embrace change and remain flexible will underscore Red Hat’s efforts to successfully promote transformation amid the pandemic. Red Hat’s reputation has historically been predicated on its open and agile approach to development and deployment, long before such attributes were considered valuable, let alone essential.

  • Red Hat: Holding Its Own and Fueling Open Source Innovation

    When IBM acquired Red Hat for $34 billion in 2019, it was considered the industry’s largest software acquisition. The synergy between the two companies led them to become one of the leading hybrid multi-cloud providers globally. In most acquisitions, the acquired entity sometimes loses momentum and sheds some of its original luster. This does not seem to be the case with Red Hat.

    One of the great things about attending in person coding conferences, such as PyCon, is the hallway track, where you can catch up with people you haven't seen for possibly a year, or maybe even the first time you've met in person. Nina is starting something like the hallway track, online, on twitch, and it's already going, so check out the first episode of Python Tea. Interesting coincidence is that this episode is kind of like a hallway track discussion between Nina and Brian.

  • LiDAR-Captured Road Data Now Publicly Available in Open-Source Machine Learning Dataset

    Scale AI says COVID-19 has shown the value of autonomous vehicles for no-contact delivery. They're making real-world road data available to train machine learning models to this end. Last week, Scale AI released PandaSet to the open-source community. According to Scale AI, PandaSet is the world’s first publicly-available machine learning dataset to include images from forward-facing solid-state LiDARs and mechanical spinning LiDARs. These two LiDAR technologies from Hesai will allow ML development teams to reap complex, real-world road data.

  • This German town replicated itself in VR to keep its tourism alive

    Nicolai Reith, Head of the Control and Communication department and advisor to the Mayor of Herrenberg, told Cities Today: “You don’t have to make a decision and then see [what happens]; you can see before you make the decision what the effect will be via the digital twin. This makes it easier to make the right decision for our city council, politicians, and citizens.”Herrenberg is already using the digital twin, which incorporates super-computing and technologies typically deployed in advanced aerospace, to visualize city data and citizens’ emotional responses to inform better decision-making. There are now plans to develop the emerging area of virtual tourism for the town, which has a population of around 31,000. “We have a very beautiful city center so tourists can explore it in a digital way with VR glasses before they come to Herrenberg, which is an interesting benefit for the future,” Reith said. [...] The team then added in geographic information system (GIS) data and traffic control systems data to incorporate topography, road geometry , and detailed traffic flows. Using the open-source fluid dynamics code OpenFOAM — which is typically used for modeling fuel injector sprays or airplane aerodynamics —they also created realistic models of the movement of wind and emissions through the city.
