  • NVIDIA Ships Vulkan Driver Beta With Fragment Shading Rate Control - Phoronix

    This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus.

    NVIDIA on Tuesday released the 455.26.02 Linux driver (and 457.00 version for Windows) that adds this fragment shading rate extension.

  • Intel Begins Adding Alder Lake Graphics Support To Their Linux Driver - Phoronix

    Intel has begun adding support for Alderlake-S to their open-source Linux kernel graphics driver.

    An initial set of 18 patches amounting to just around 300 lines of new kernel code was sent out today for beginning the hardware enablement work on Alderlake-S from the graphics side.

    Yes, it's only a few hundred lines of new driver code due to Alder Lake leveraging the existing Gen12/Tigerlake support. The Alder Lake driver patches similarly re-use some of the same workarounds and changes as set for the 14nm Rocket Lake processors with Gen12 graphics coming out in Q1.

  • AMD Linux Driver Preparing For A Navi "Blockchain" Graphics Card - Phoronix

    While all eyes are on the AMD Radeon RX 6000 "Big Navi" graphics cards set to be announced next week, it also looks like AMD is preparing for a Navi 1x "Blockchain" graphics card offering given the latest work in their open-source Linux driver.

    Patches posted today provide support for a new Navi graphics card referred to as the "navi10 blockchain SKU."

    The Navi 10 part has a device ID of 0x731E. From the AMDGPU Linux kernel driver perspective, the only difference from the existing Navi 10 GPU support is these patches disable the Display Core Next (DCN) and Video Core Next (VCN) support with this new SKU not having any display support.

Tiger Lake + Renoir On Ubuntu Linux For Battery vs. AC Performance

Given the recent Intel presentation alleging AMD Ryzen laptop performance being worse on battery relative to the AC vs. battery performance seen with Intel EVO notebooks featuring Tiger Lake processors, I ran a mini comparison on my side to see whether there is any merit to Intel's information when testing under Ubuntu Linux. Here is just some initial data on my side when benchmarking AMD Ryzen "Renoir" versus Intel Core i7 "Tiger Lake" when running Ubuntu 20.10 and comparing the AC power versus battery performance.

Open Hardware: Raspberry Pi 4 and Arduino

  • Vulkan for the Raspberry Pi 4 with V3DV is now conformant and official | GamingOnLinux

    Great news for the Vulkan API and for fans of the Raspberry Pi 4, as the upcoming V3DV that will be part of the next Mesa release is now an official conforming driver. Sharing the news on the official RPi blog, guest poster Iago Toral from Igalia announced that nearly a year after being first announced, the V3DV Vulkan driver for the Raspberry Pi 4 now passes The Khronos Group's Vulkan 1.0 conformance tests and is now officially listed.

  • The smart video doorbells letting hackers into your home
                     
                       

    We tested 11 different doorbells found on eBay and Amazon, many of which had scores of 5-star reviews, were recommended as ‘Amazon’s Choice’, or on the bestseller list. One was labelled as the number one bestseller in ‘door viewers’. We found vulnerabilities with every single one.

  • Homemade recycling rig turns plastic waste into new products

    While that plastic cup, bag, dish, or other item may have served its purpose, more than likely it could be formed into something new. With this in mind, the SOTOP-Recycling team of Manuel Maeder, Benjamin Krause, and Nadina Maeder developed an automated injection molding machine that can be built at home and is small enough to allow you to run your own recycling operation! [...] Everything is controlled by an Arduino Mega.

  • Delock MQTT-enabled power socket switches

    The included leaflet is sufficient to get started. Plugging the device into mains has it create a WiFi access point I connect to, and I can then configure it to connect to my home network. The Tasmota firmware spoke German to me all the time, and the only reason I can think of, as my browsers are all set to English, is that it was built that way for delivery here. Ronald confirms that and explains I can flash the device with an en firmware from here (I pasted the link to tasmota.bin into the firmware update page).
