While Intel is normally quite good with their new hardware support being in good shape well ahead of launch, their new code for supporting the ENQCMD functionality for the Data Streaming Accelerator (DSA) with Xeon "Sapphire Rapids" has been an exception. This summer the mainline Linux kernel disabled ENQCMD support since the code was "broken beyond repair" while now Intel engineers have sent out a new series looking to get it re-enabled.

An Open Printing micro-conference took place today during the Linux Plumbers Conference 2021 week. While it's hard to get excited about printers in 2021, it is exciting the renewed effort around CUPS with it now being back to effectively led by the community and CUPS founder Michael Sweet who left Apple. CUPS 2.4 is coming as the first feature release in quite a while and then CUPS 2.5 followed by CUPS 3.0 are already being talked about with features being discussed.

While Oktoberfest was once again cancelled due to the COVID-19 pandemic (then again, due to the state of the ad industry / ad-block users we haven't had any European meet-up / open-source gathering in years), the wiesn would have kicked off this past weekend. So as is tradition, there is the Phoronix Premium Oktoberfest sale where you can join the ad-free service as a reduced rate. If you enjoy the daily, original Linux and open-source content on Phoronix with plenty of benchmarking, you can do so at a reduced rate.

With the m68k community continuing to be active around supporting the vintage Motorola 68000 series with modern open-source software, Rust has now merged support for these old processors.

Earlier this year AMD went public with prototyping CRIU support for Radeon GPUs around ROCm to be able to checkpoint/freeze running compute workloads and to then restore them at a later point. This CRIU focus is driven by their big accelerator needs and forthcoming supercomputers for migrating workloads particularly within containers. AMD continues working on CRIU support for GPUs and last week provided an update on the project.

The recently released SDL 2.0.16 brought much-improved Wayland support but it's still not quite good enough yet to have it be the default over the SDL X11 path. However, developers continue working in that direction to eventually use it by default.

One has to wonder how much longer the Linux kernel will keep around some very old and known to be borked hardware support but at least for now the DECpc AXP 150 "Jensen" platform support is sticking around and with Linux 5.15 is no longer marked as "broken" outright.

BayLibre developer Alexandre Bailon has posted a "request for comments" of a new open-source Direct Rendering Manager (DRM) driver for AI Processing Unit (APU) functionality. Initially the driver is catering to Mediatek SoCs with an AI co-processor but this DRM "APU" driver could be adapted to other hardware too.

The latest patches sent out for review/testing on the long mission for enabling Apple M1 support on Linux is the USB Type-C connectivity.

As reported at the start of August, AMD and Valve have been working on Linux CPU performance/frequency scaling improvements with the Steam Deck being one of the leading motivators. As speculated at that time, their work would likely revolve around use of ACPI CPPC found with Zen 2 CPUs and newer. Published last week was that AMD P-State driver for Linux systems indeed now leveraging CPPC information. AMD formally presented this new driver yesterday at XDC2021.

There's still some time to go before seeing the long-awaited GIMP 3.0 release for this open-source image manipulation program but at least out this weekend is GIMP 2.10.28 for bettering the current stable series.

Along with releasing Plasma 5.23 Beta this week, KDE developers have been busy on driving in a bunch of Plasma Wayland fixes and other refinements to their stack.

One of the areas where Linux has struggled on the desktop has been around HDR (high dynamic range) display support while that will hopefully be addressed in the coming months with Red Hat hiring an engineer to focus on that problem.

Developers are hoping for next year's GCC 12 release they will have Apple AArch64 support on Darwin in place for being able to support Apple Silicon -- initially the M1 SoC -- on macOS with GCC.

Longtime Mesa developer Karol Herbst who has worked extensively on the open-source NVIDIA "Nouveau" driver as well as the OpenCL/compute stack while being employed by Red Hat is now toying with the idea of Rust code inside Mesa.

The unplanned Ubuntu 18.04.6 LTS release is available today that was made on short notice for addressing unbootable media with Ubuntu 18.04.5.

Along with bringing up DG2/Alchemist graphics card support on Linux, Intel engineers have been working to square away their support for the DG1 developer graphics card. This week thanks to XDC2021 is a fresh status update about what is working with this initial Intel graphics card on their open-source driver and what remains in the works.

As covered several times going back to the end of last year, ACPI Platform Profile support has materialized in recent versions of the Linux kernel for the core infrastructure and implementations that work with the latest laptops from the likes of Dell, Lenovo, ASUS, and HP. This platform profile support is becoming increasingly important with expressing your power/cooling/performance preference so that your laptop behaves as one would expect.

It looks like Intel's ISHTP_ECLITE driver will be ready for mainlining in Linux 5.16 as a driver for newer systems skipping out on a traditional embedded control (EC) and instead using this EC-like IP as part of their Programmable Service Engine subsystem.

Those reading Phoronix over the years likely know the X.Org Server has had an increasing number of vulnerabilities come to light in recent times and statements by security researchers like the security being even worse than it looks. Given the age of the X.Org/X11 codebase and many components being rather unmaintained these days, the security situation isn't that great combined with a lack of manpower. The security topic was under the spotlight today at the XDC2021 conference.

Following the big OpenZFS 2.1 release from July that brought Distributed SPARE RAID, a compatibility property for pools, and other new features, OpenZFS 2.1.1 is available today as a follow-up release for this open-source ZFS file-system implementation for Linux and FreeBSD systems.
