SiFive's HiFive Unmatched is the best, readily available RISC-V developer board at the moment with enough horsepower for modest development/porting work and continues seeing improvements with the mainline Linux kernel. But availability on HiFive Unmatched is beginning to dry up and SiFive isn't planning on any further production runs as it begins focusing on the board's successor...

Landing today for Mesa 22.0 was a fix for Vulkan ray-tracing with the RADV driver in the RDNA Wave32 shader mode and then switching to Wave32 by default for ray-tracing on RDNA/RDNA2 GPUs...

Earlier this week the Linux Vendor Firmware Service began surging with activity following many new system firmware files being uploaded for what appears to be a "high severity upcoming security issue" but currently undisclosed. That issue hasn't been made public yet, but after poking around it is updating the Intel CPU microcode.

After recently carrying out the Core i5 12400 Linux benchmarks against other modern processors, for curiosity I ran some benchmarks on some older hardware going back to AMD Kaveri and Intel Sandy Bridge for a look at how the modern Ubuntu performance compares across all those systems...

For the past several years the X.Org Foundation has been part of Software in the Public Interest (SPI) but are now considering other possible arrangements moving forward...

On top of all the GPU driver feature changes to merge last week, yesterday marked the first batch of "fixes" sent in to Linux 5.17 for the Direct Rendering Manager drivers. Notable from this batch of fixes is getting GPU recovery enabled for Yellow Carp / Rembrandt APUs...

The RTC subsystem changes have been submitted for the in-development Linux 5.17 kernel ahead of its merge window winding down this weekend...

To date the Intel Linux graphics driver has supported Intel's DG2 "Alchemist" G10 and G11 sub-platforms/variants as the main designs to this point. However, at the end of last year we began seeing "G12" references surface in their compute stack and now the Intel open-source Linux kernel driver is formally preparing the DG2-G12 variant support...

In addition to the Fedora / Red Hat Anaconda installer working on a web-based implementation, openSUSE/SUSE is also exploring a web-based installation front-end built atop their existing YaST. They are developing this new web front-end as the "D-Installer" project...

Red Hat with the Fedora community have been working for years now to make Cockpit very capable for a web-based interface for administering Linux servers. In addition to this year working on shifting their Anaconda installer to a web-based interface that makes use of Cockpit, from this web management portal they are wanting to make it easier to setup file sharing with NFS and Samba...

When it comes to OpenGL extension support, the Zink generic OpenGL-on-Vulkan implementation now has as robust coverage as core Mesa offers and what is implemented by the LLVMpipe software driver, RadeonSI Gallium3D, and the Intel i965 drivers...

A handful of new AMD Radeon open-source GPU sofware releases were made today for developers...

The long time Phoronix reader, with an excellent long-term memory, may remember an odd article from back in August 2017 on buying a passively cooled computer. It tells the tale of the consumer who decided to buy a rather niche, fanless, therefore passively cooled computer.

Way back in August Intel posted a set of Linux kernel patches for supporting "unaccepted memory" by the Linux kernel in preparation for next-generation Xeon processors and speeding up the boot time for guest virtual machines making use of Intel's Trust Domain Extensions (TDX) security feature. Unaccepted memory support hasn't yet made it to the mainline kernel but now a second iteration of the patches have been posted...

Over the years the Linux kernel has picked up many different sanitizers, memory leak detectors, and other features for helping to diagnose and address deficiencies in the kernel. However, all of these debugging-optimized features aren't centrally located that can make it difficult for system administrators and developers to spot these numerous features when configuring a kernel build manually. Now with Linux 5.17 that is changing...

Last week I noted about EDAC changes in Linux 5.17 for future AMD CPUs. The "Error Detection and Correction" work included AMD adding RDDR5 / LRDDR5 support to their driver and new CPU model IDs that appear to be for Zen 4. Also working on next-gen AMD processor support in Linux 5.17 are recent SMCA changes...

I've been writing about Genode OS for over a decade as one of the interesting original, open-source operating system frameworks that has taken novel approaches to many design elements and continues persevering with their efforts. For 2022 the project has yet more ambitious goals ahead...

F2FS as the Flash-Friendly File-System may not see too much use out of desktop Linux distributions at least as it concerns any easy/semi-endorsed root install option, but this file-system does continue maturing and seeing much use by enthusiasts and especially among the plethora of Android devices now supporting this flash-optimized file-system. With Linux 5.17, F2FS has some performance improvements and other fixes...

SUSE today formally announced SUSE Liberty Linux as its support offering for mixed Linux environments within enterprises...

The race is on for delivering XWayland 22.1 in time for the spring Linux distribution releases with at least Fedora Workstation 36 expected to carry this updated package for allowing X11 clients to work atop Wayland compositors...
