Mesa 20.3 Released With Big Improvements For Open-Source Graphics Drivers

Mesa 20.3 has been released as the Q4'2020 open-source graphics driver update, primarily around providing OpenGL and Vulkan support on the likes of Intel and AMD Radeon graphics along with the reverse-engineered Nouveau support, many smaller drivers especially in the embedded space, and the growing list of CPU-based implementations and other translation efforts.

AMD Is Making Progress On Open-Source Firmware - Initially With OpenBMC

While we are still waiting to see what AMD might do for returning to open-source AGESA or better supporting Coreboot and the like, they are making some inroads with open-source firmware support -- beyond the context of Chromebooks where they continue to engage due to Google's engineering requirements. AMD is working to "align with the industry direction of open-source firmware stacks" with their initial focus being on open-source OpenBMC firmware support for their server platforms.

C++20 Is Still Settling While LLVM Clang Already Adds Option For Starting C++2b/C++23

It was just in September that the C++20 standards draft was approved as a major update to the programming language over C++17. While compilers like GCC and LLVM Clang are still completing all of the changes for C++20 support, Clang is already moving ahead and has added support for the "-std=c++2b" option as it begins the endeavor of staging changes likely for C++23.

Dbus-Broker 25 Released With More Fixes

The BUS1 kernel code for providing an in-kernel, capability-based IPC mechanism hasn't seen much (or any?) activity in well over a year but at least the Dbus-Broker project continues ahead. Dbus-Broker continues ahead as this D-Bus compatible implementation focused on correctness while being optimized for performance.

The Spectre Mitigation Performance Impact On AMD Ryzen 5000 "Zen 3" Processors

For those wondering what the current cost is to the default Spectre mitigation protections on the new AMD Ryzen 5000 series "Zen 3" processors, here are a set of performance tests looking at that overhead with the still relevant mitigations applied by default and then if forcing them off. The Zen 3 mitigation overhead was compared then to similar AMD Zen 2 and Zen+ processors.

Intel Begins Upstreaming Work For Their Vision Processing Unit On Linux

While Intel engineers over the course of the year began upstreaming various elements of the Keem Bay SoC support, the actual Vision Processing Unit (VPU) enabling hasn't been sent out for review until now. Intel has sent out their initial patches for bringing up the Vision Processing Unit on the open-source Linux kernel.

Intel Begins Preparing Linux Graphics Driver Support For Xe HP As "Gen12.5"

Xe HP is Intel's discrete GPU aiming to compete against the latest-generation AMD and NVIDIA compute accelerators. Xe HP isn't scheduled to reach general availability until well into 2021 while now as they begin ramping up their sampling of Xe HP to potential customers, the Linux open-source driver support is preparing to roll-out.

NVIDIA GeForce RTX 3060 Ti Linux Performance Exceeds The RTX 2080 SUPER - Costs Just $399 USD

NVIDIA tomorrow is launching the GeForce RTX 3060 Ti with their Founder's Edition card and AIB variants are also expected. For about $400 USD, the GeForce RTX 3060 Ti offers performance comparable or slightly faster than the GeForce RTX 2080 SUPER and especially much stronger performance for compute and RTX workloads. With the review embargo now lifted a day ahead of the launch, here are the initial Linux benchmarks of the GeForce RTX 3060 Ti under Ubuntu Linux.

Another Linux FBDEV Driver Poised For Removal In Favor Of Superior DRM Alternative

For years there have been calls to deprecate Linux's FBDEV and work around replacing FBDEV drivers with modern Direct Rendering Manager (DRM) drivers. While hardware vendors are now trending in the direction of DRM drivers (and the FBDEV emulation support if needed) after the embedded space was somewhat of a holdout, FBDEV drivers and the subsystem still exist as we roll into 2021. But at least one more FBDEV driver is now looking likely for removal in favor of its modern and maintained DRM counterpart.

RADV Vulkan Driver Enables NGG For AMD VanGogh APUs

Up to now the Mesa Radeon Vulkan driver "RADV" has only enabled Next-Gen Geometry (NGG) support by default for discrete graphics cards. But now that requirement is lifted for supporting NGG on forthcoming GFX10.3 (RDNA 2) APUs.
