Among many other sound driver changes destined for the upcoming Linux 5.17 cycle, Cirrus Logic has contributed CS35L41 HD audio codec support in the form of a new sound driver, cs35l41_hda...

While our testing has consistently shown how Clear Linux can deliver leading performance on Intel/AMD x86_64 platforms, one of the user criticisms to that distribution has been around the limited selection of packaged software especially on the desktop side. But the rather interesting Distrobox can help address that by leveraging Podman or Docker to run other Linux distribution user-space software packages atop...

What may end up being one of the greatest Linux kernel features of 2022 is the recently published "Fast Kernel Headers" effort for cleaning up the kernel headers and dramatically speeding up Linux kernel builds both for absolute/clean and incremental builds. Fast Kernel Headers can cut the Linux kernel build time in half or greater and out this weekend are the v2 patches...

The Linux 5.16 stable kernel is slated for release tomorrow and it delivers on some grand improvements to kick off 2022. But as for great as the Linux 5.16 features are, we are already looking forward to the enhancements on deck with Linux 5.17...

It should hardly come as a surprise given Fedora's history of always shipping with the very latest GNU Compiler Collection (GCC), but with this spring's Fedora 36 the plan is to ship with the yet-to-be-released GCC 12 and other very latest open-source compiler toolchain components...

Here is a look at the many GPU/display driver updates for this next kernel version...

Across dozens of articles over the past year I have covered a variety of different open-source AMD Radeon Linux graphics driver optimizations from their kernel driver through their Mesa RadeonSI Gallium3D driver and the popular RADV Vulkan driver, among other interesting open-source AMD contributions. For those wondering what the cumulative gain was for 2021 from all these AMD graphics driver changes, here are some end-of-year 2020 vs. 2021 benchmarks across a number of different Linux games while testing on Vega, Navi, and Navi 2 graphics cards.

A few minutes ago a new Ubuntu blog post hit the wire entitled "The Future of Snapcraft" where immediately I wondered if it was announcing plans to move away from their own app packaging/store/update tech and shift over to a Flatpak world like the rest of the Linux ecosystem for app sandboxing, app store, and distribution. Nope, but they are going to overhaul Snapcraft's architecture...

As part of the plethora of networking changes for Linux 5.17, NVIDIA is introducing support for Spectrum-4 networking ASICs...

As part of the various end-of-year Linux comparisons that I've made a habit of over the past 17 years, with the EOY 2021 benchmarking I was rather curious to see how Intel's Clear Linux distribution has evolved Xeon Scalable "Ice Lake" performance since that platform launched in Q2'2021. It turns out there have been some terrific optimizations squeezed out of that latest-generation Xeon Scalable platform on Intel's Clear Linux. In this article is a look at the Ubuntu and Clear Linux performance on the flagship Xeon Platinum 8380 2P reference server back around the time Ice Lake launched and then again using the latest software packages that closed out 2021.

For those assigning VFIO devices to guest virtual machines, the initialization/start-up process may soon be much faster with a set of patches volleyed by Oracle...

In preparation for Xeon Scalable "Sapphire Rapids" processors, Linux 5.16 adds support for Advanced Matrix Extensions. But that AMX bring-up is more invasive than when introducing AVX as with AMX the feature needs to be "requested" for use by user-space, among other changes. As such extra handling also needed to be introduced for the Kernel-based Virtual Machine (KVM) that hadn't made it for v5.16 but now it looks like the AMX KVM support may be ready for mainline...

Longtime Linux users will likely recall when it was commonplace to modify /etc/sysconfig/network-scripts/ifcfg-* files for managing your network connections. Fortunately, that's largely a thing of the past and Fedora 36 is looking to remove support for those legacy network configuration files from new Fedora installs...

It looks like EXT4 with Linux 5.17 will finally be supporting the FS_IOC_GETFSLABEL and FS_IOC_SETFSLABEL ioctls that several other prominent file-systems have been supporting the past few years...

Mutter landed a prominent addition today for GNOME 42: the Wayland compositor now supports the recently introduced DMA-BUF feedback extension...

After the many years now that AMD's RadeonSI Gallium3D driver has been seeing relentless optimizations for GCN and now RDNA GPUs paired with the fact more Linux games targeting Vulkan (or going through Direct3D to Vulkan), one might think in 2022 that the OpenGL driver optimization efforts would let up... But that doesn't appear to be the case with well known AMD RadeonSI developer Marek Olšák pursuing yet more optimizations...

2022 will hopefully be the year that PipeWire becomes commonplace on desktop Linux distributions for managing both audio/video streams. New PipeWire releases come quick in working to address remaining gaps in this Red Hat led solution and ensuring it can fulfill the use-cases previously handled by the likes of PulseAudio and JACK...

Back in 2020 Microsoft announced their "Pluton" security chip that woulld be coming to future AMD, Intel, and Qualcomm processors. The Pluton security processor is designed to improve the system security under Windows and now we find out that AMD's forthcoming Ryzen 6000 "Rembrandt" mobile processors will be the first featuring this security feature that may prove controversial to Linux/open-source fans...

Last week I called attention to the new "x86-android-tablets" driver being prepared for introduction in Linux 5.17. That driver aims to fix up the mess of various x86 Android-focused tablets failing to run off the mainline Linux kernel or having various device issues in doing so. Since that prior article, more patches have been posted to address additional tablet issues...

A decade old patch is set to be mainlined in the upcoming Linux 5.17 that has been carried by Google's Chrome OS kernel build for years and can help with security on Linux systems not relying upon systemd's udev...

It was nearly one year ago that Arm announced the Armv9 architecture as the successor to ARMv8 that was introduced a decade ago. Since then Arm has been working on adding Armv9 support to the open-source compilers such as GCC and LLVM/Clang. That initial Armv9 support has been in place for months now while on the LLVM/Clang today it received support for Armv9.3-A as the latest iteration...

Next month marks two years since AMD introduced the Ryzen Threadripper 3990X 64-core / 128-thread processor. All of our testing of the 3990X on Linux over the past two years has been with the System76 Thelio Major, which continues holding up well with that US-assembled workstation with hand-crafted enclosure from Colorado. With System76 having recently released Pop!_OS 21.10 as the latest update to their Ubuntu Linux derived operating system and upcoming two year anniversary of the 3990X, it made for an interesting time to see how the performance of the Ryzen Threadripper 3990X and Radeon RX 5700 XT within that workstation has evolved.
