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.

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.

Xilinx Continues Their Open-Source FPGA Upstreaming Push For The Linux Kernel

Earlier this month we covered the news of Xilinx is looking to upstream their open-source "AI Engine" driver to the Linux kernel. This comes as Xilinx and AMD are working on Radeon Open eCosystem (ROCm) support for their FPGAs with AMD being in the process of acquiring the FPGA giant. Now more open-source code is looking to be included in the Linux kernel tree.

SVT-AV1, Dav1d Speeding Along AV1 Into 2021

While consumer GPUs are reaching market with AV1 decode acceleration, there still is the matter of the various media APIs and multimedia software making use of it. In cases where that is missing or the user doesn't yet have a supported Tiger Lake / Ampere / RDNA2 GPU, the dav1d decoder remains the fastest open-source CPU-based AV1 decoder. Similarly, SVT-AV1 remains the fastest CPU-based AV1 encoder available.
