Kernel: Linux IO_uring and "amd-pstate"

  • Linux IO_uring Can Now Achieve Up To ~3.8M IOPS Per-Core - Phoronix

    It was just last month when ~3.5M IOPS per-core was impressive with the code for Linux 5.15 to further push Linux's I/O limits. Now for code likely to be included in Linux 5.16 it's currently at 3.8M IOPS with a single tread.

    With this patch series reworking and further optimizing the submission and completion paths, the I/O throughput is upped even more. With block maintainer and IO_uring lead developer Jens Axboe's Intel Optane based rig, he is enjoying around a 3% throughput improvement.

  • Updated AMD P-State Driver Published For Linux - Phoronix

    Earlier this month AMD published their "amd-pstate" Linux driver that leverages ACPI CPPC data to make more informed CPU frequency scaling decisions with an aim to boost the performance-per-Watt for Zen 3 (and eventually Zen 2) processors on Linux. The second spin of that "amd-pstate" Linux kernel driver is now available for testing.

Review: Auxtral 3

At the beginning of this review I mentioned Auxtral reminded me of Linux Mint Debian Edition. The theme, the Cinnamon desktop, and general look of the project certainly held that first impression. However, the default applications and tools (apart from the Cinnamon desktop and command line utilities) felt quite a bit different. Linux Mint has been around for several years and has earned a reputation for being beginner friendly, polished, and shipping with a lot of top-notch open source applications. Auxtral appears to have a similar approach - similar base distribution, the same desktop environments, and a similar look. However, Auxtral does have its own personality under the surface. It ships with a quite different collection of applications, sometimes using less popular items (Brave in place of Firefox, SMPlayer instead of VLC, etc.) It has also gone its own way with software updates, preferring classic tools like APT and Synaptic over Mint's update manager. Auxtral is off to a good start. This was my first time trying the distribution and the experience was mostly positive. The operating system is easy to install, offers multiple desktop environments, and walks a pretty good line between hand holding and staying out of the way. The application menu is uncluttered while including enough programs to be useful. Some of those programs are a bit more obscure or less beginner friendly than what you might find in Linux Mint, but otherwise it's a good collection. Virtually everything worked and worked smoothly. I was unpleasantly surprised by this distribution's memory usage, most projects consume about half as much RAM, but otherwise I liked what Auxtral had to offer. I might not recommended it to complete beginners, especially since the project does not appear to have any documentation or support options of its own, but for someone who doesn't mind a little command line work or who likes the idea of an easy to setup distribution that combines Debian with the Cinnamon (or Xfce desktop) this seems like a good option.

9to5Linux Weekly Roundup: October 17th, 2021

This week was all about Ubuntu 21.10, but we also saw some big announcements starting with the release of the KDE Plasma 5.23 desktop enviornment and the launch of the PinePhone Pro Linux smartphone, and continuing with several great distro releases like the systemd-free Devuan GNU+Linux 4.0 and KaOS 2021.10. You can enjoy these and much more in 9to5Linux’s Linux weekly roundup for October 17th, 2021, below. Last but not least, this week I also managed to do some further optimization to the website so that it runs faster, and cleaned up the bottom part of the posts pages to make the comments section more accessible.
