In addition to the prompt support for Qualcomm's Snapdragon 8 Gen 1, another exciting milestone for the in-development Linux 5.17 kernel is introducing mainline support for the StarFive JH7100, which has been trying to make its debut as the first usable and low-cost RISC-V platform...

The GNU Compiler Collection (GCC) that serves as the default system compiler on most Linux distributions is nearing its annual update with GCC 12. GCC 12 has been in a general bug fixing period since November while beginning next week will be onto its final phase of focusing just on regression and documentation fixes to the compiler...

Qualcomm only announced the Snapdragon 8 Gen 1 and X65 platforms at the end of November but already they have managed to provide timely mainline support for these latest high-end SoCs. This is great to see compared to the days of slow to materialize mainline support for new Arm SoCs, which still persists among some vendors with either belated mainline support or only focusing on vendor downstream kernels. The big batch of Arm SoC/platform changes have landed for Linux 5.17...

As expected the Linux 5.16 kernel has been promoted to stable...

Back on Christmas Eve I noted how the Linux 5.16 performance was looking real good for AMD APUs as a performance improvement not widely noted to that point with significant uplift over Linux 5.15 stable. The good news is Linux 5.16 is set to debut as stable today and the benchmark results with AMD APU graphics is looking very promising after carrying out tests on additional available systems.

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...

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...
