Linux Schedutil Governor's Quirky Behavior Persists In 2023

Fri, 02/10/2023 - 00:00
Earlier this week I posted benchmarks looking at how the AMD Ryzen Threadripper 3990X performance has evolved in the three years to the day since that 64-core / 128-thread HEDT chip launched. While overall the Threadripper 3990X performance has evolved nicely under Linux since 2020, when it came to the video encoding tests in particular they performed worse overall. As I had raised in that earlier article and now elaborated with some follow-up tests, that regression is driven by the default "schedutil" frequency scaling governor used by default.

Intel's Mesa Drivers Begin Preparing For The New Xe Kernel Driver

Thu, 02/09/2023 - 22:00
One of the open-source Intel Linux graphics driver milestones we have to look forward to this year is the introduction of the new "Xe" kernel graphics driver to effectively succeed the existing "i915" Direct Rendering Manager driver for recent generations of Intel graphics. More prep code was merged this week to Mesa's Intel "ANV" Vulkan driver in preparing to be able to make use of that new kernel mode driver once its upstreamed into the Linux kernel...

A Call For More Collaboration & Harmony Among BSD Hardware Drivers

Thu, 02/09/2023 - 19:36
The BSD operating system projects tend to not receive as much support from hardware vendors as Linux and their driver support is made even more fragmented on the BSD side due to many subtle as well as not so subtle differences between the major BSDs. NetBSD developer Pierre Pronchery has proposed more "harmony" among BSD drivers with increased collaboration between the major BSD players on driver development...

Linux Disabling High Resolution Scrolling For Logitech Devices Connected Via USB

Thu, 02/09/2023 - 06:02
While there's been a multi-year effort for Wayland high resolution scrolling, support by the desktop environments for this functionality, and all the other infrastructure work, high resolution scrolling is proving to still be a challenge for Linux in 2023. The latest is now the Linux kernel dropping Logitech high resolution scrolling for mice connected via USB until further improvements can be made...

AMD Ryzen Threadripper 3990X Linux Performance After Three Years

Wed, 02/08/2023 - 00:30
Today marks three years since AMD introduced the Ryzen Threadripper 3990X, the first HEDT chip sporting 64 cores / 128 threads. While based on Zen 2, the shear multi-threaded compute power of the Threadripper 3990X still bodes well today. Besides 64 cores / 128 threads still being a lot, Linux software improvements over the past three years have helped maintain the competitiveness of the Threadripper 3990X. In today's benchmarks are results from the System76 Thelio Major as tested back in 2020 based on Pop!_OS / Ubuntu 22.04 LTS compared to the very latest state today when running an Ubuntu 23.04 snapshot on the same system and using a Linux 6.2 Git kernel.
