As a surprise and big disappointment, the "amd_energy" driver that exposes AMD EPYC server CPU energy monitoring metrics under Linux for being able to calculate the per-core and package power consumption and more is now set to be removed from the mainline Linux kernel.

Greg Kroah-Hartman has banned a US university from trying to mainline Linux kernel patches over intentionally submitting questionable code with security implications and other "experiments" in the name of research.

HiSilicon engineers continue working on a cluster scheduler that could help the performance of certain x86 and ARM platforms on Linux.

While AMD's Mantle graphics API development has been suspended for more than a half-decade already with the Vulkan API successfully taking off, the open-source GRVK project continues to let Mantle unofficially live on by re-implementing its interfaces over Vulkan.

Well known open-source AMD Linux graphics driver developer Marek Olšák published an initial proposal this week as "a redesign of how Linux graphics drivers work."

Last week 4A Games released Metro Exodus for Linux and while there were a few issues at launch, at least one of them is now resolved.

It's fairly common that many longtime Linux kernel developers use their personal email addresses for signing off on kernel patches or dealing with other patch work, especially when they are engaging with kernel development in their personal time too and occasionally jumping between employers over time while still sticking to interacting with the upstream kernel community, etc. There are also understandably some companies that mandate the use of their corporate email addresses for their official work/patches while now IBM seems to be taking things one step to the extreme.

It's been over one year already since the debut of DragonFlyBSD 5.8 while fortunately DragonFlyBSD 6.0 will be here soon for this popular BSD operating system.

Microsoft is preparing the Linux kernel for some yet-to-debut Azure network functionality.

Of the many new features coming with Linux 5.12 is KFence, short for the Kernel Electric Fence. KFence is a low-overhead memory safety error detector/validator for the kernel with lower expected overhead costs than say the Kernel Address Sanitizer. I just wrapped up some benchmarks looking out for any overhead impact of KFence on Linux 5.12 in its near-final state.

Google announced today that with Android 12.0 they will be deprecating their RenderScript APIs. Moving forward Android developers should primarily target the Vulkan API for high performance compute needs.

The first release candidate is up for version 1.7 of the Portable Computing Language, the portable OpenCL implementation that can run on CPUs and other accelerators. With POCL 1.7, OpenCL 3.0 is now being exposed and there is also improved support for SPIR-V binaries on CPUs.

It's been just one week since the release of Vulkan 1.2.175 that introduced the Vulkan Video extensions while out this morning is now the Vulkan 1.2.176 revision.

Red Hat graphics driver developer David Airlie has tried running the DOOM (2016) game on the CPU-based Lavapipe Vulkan driver... It works, but isn't fast and currently requires some hacks.

Alyssa Rosenzweig, known for her work on the Panfrost open-source driver for Arm Mali graphics, has published the latest findings around the Apple M1 graphics processor. In fact, enough understanding to get a shaded, spinning cube rendering on the Apple M1 using a simple demo so far while the open-source driver support is still the goal.

While normally after seven weekly release candidates the next stable Linux kernel release is declared, Linux 5.12 is one of those special kernels needing at least an eighth RC before going gold.

While Arch Linux now has its own convenient installer for quick and easy Arch installs, for those in search of an out-of-the-box, desktop-friendly Arch based Linux distribution Endeavour OS remains one of the leading options in 2021.
