The newest Linux hardware support patches for the kernel revolve around i2c bus sharing support for newer SoCs where the i2c bus is being shared by AMD's Platform Security Processor (PSP). This i2c controller is based on common DesignWare IP but new kernel code is being crafted for handling that bus sharing between the kernel and the PSP co-processor...

While not talked about as much as raw performance and other factors, but in the recent testing of the Lenovo ThinkPad T14s Gen2 laptop with AMD Ryzen 7 PRO 5850U, it was observed that the GNOME Wayland session by default on Ubuntu 21.10 is delivering better battery life / lower power consumption than using the GNOME X.Org session...

Last week I wrote about the interesting HIPSPV back-end for LLVM to take AMD HIP code -- which generally starts off as NVIDIA CUDA code to begin with before the HIP-ification -- and to be able to output that from the LLVM compiler stack as the SPIR-V intermediate representation used across OpenCL and Vulkan drivers. The goal with this is to be able to take AMD HIP code and ultimately be able to run it on Intel graphics processors but potentially other vendors/drivers too given the vendor-neutral SPIR-V. More of that HIPSPV work is now hitting mainline LLVM...

It was just over one week ago the systemd 250 release candidate was issued (along with a brown paper bag 250-rc2 fix-up release). Systemd 250 has a ton of changes for this init system and more while today systemd 250-rc3 was released with yet more changes in tow...

Last year with Linux 5.10 FUSE added DAX support for use with VirtIO-FS. Like with DAX for other file-systems, enabling this direct access mode allows bypassing the page cache. For use-cases when running on persistent memory like devices or VirtIO, having this direct access to the storage device can be beneficial for performance. With Linux 5.17 FUSE is expanding the DAX support to allow per-inode control as well...

It's been a while since last comparing the Apple macOS performance to Linux since in part because the newer Apple Silicon (M1) hardware isn't yet in good enough shape for performance tests on Linux. But for those wondering about the Intel-powered Macs and how the performance of the latest Linux distributions compare to that of macOS 12 Monterey, here are some benchmarks of the new macOS 12.1 up against Ubuntu 20.04.3 LTS, Ubuntu 21.10, and Intel's own Clear Linux.

Since early 2020 Micron went public with HSE as an open-source storage engine for SSDs and persistent memory. The HSE key-value store proved to be extremely performant with the likes of a MongoDB implementation but required changes to the Linux kernel that made it initially a higher barrier for entry. HSE 2.0 shipped in October that no longer required those kernel changes while still offering blistering fast performance. Now to round out the year they have HSE 2.1...
