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.

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...

OpenZFS 2.0 has been officially released! OpenZFS 2.0 marks a major step forward for open-source ZFS file-system support for what started out as ZFSOnLinux but is now OpenZFS with unified FreeBSD and Linux support (macOS support is still being pursued as well) and this release also bringing many new features...

With the X.Org Server being "abandonware" but at the same time the upstream XWayland portion of the codebase continuing to be worked on, Fedora developers at Red Hat are looking at splitting XWayland into its own standalone package to make it easier to ship it without having to use the rest of the xorg-server code-base...

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...

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...

One area not talked about much for Intel's latest Tiger Lake processors are hardened CPU security mitigations against the various speculative execution vulnerabilities to date. What's peculiar about Tiger Lake though is now if disabling the configurable mitigations it can actually result in worse performance than the default mitigated state. At least that's what we are seeing so far with the Core i7 1165G7 on Ubuntu 20.10 Linux is the opposite of what we have been seeing on prior generations of hardware.

Intel's Linux graphics driver developers have submitted their final batch of feature changes targeting the Linux 5.11 kernel...
