Google Taps More Performance Out Of AMD Zen CPUs With BPF-CCX Scheduling

For helping with thread placement on modern AMD Zen systems with multiple CPU core complexes, Google has been developing "BPF CCX" that leverages the Linux kernel's eBPF capabilities paired with a user-space agent for fine-grained thread control. Google has found very positive performance results out of their use of this alternative means of high performance scheduling for achieving even greater performance on AMD processors under Linux...

Linux 6.19's Significant ~30% Performance Boost For Old AMD Radeon GPUs

For those still using old AMD GCN 1.0 "Southern Islands" or GCN 1.1 "Sea Islands" graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy "Radeon" DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.

NVIDIA's Quest For A "Safe" Linux Kernel For Automobiles, Robotics

NVIDIA engineer Igor Stoppa presented at the Linux Plumbers Conference (LPC) earlier this month around using Linux in safety-critical environments like automobiles and the current shortcomings of the upstream Linux kernel and the challenges on achieving Automotive Safety Integrity Level (ASIL) certifications around the Linux kernel. It's an interesting read/watch around the safety of Linux (or not) for such strict safety environments...

Intel Prepares For KVM Guest VMs To Support Advanced Performance Extensions (APX)

Since Linux 6.16 the Intel APX support has been ready for the kernel infrastructure and goes along with the compiler toolchain support for Advanced Performance Extensions with the likes of GCC and LLVM/Clang. The latest element being worked on for APX enablement in the open-source/Linux world is for allowing KVM guest virtual machines (VMs) to make use of APX...

WMI Marshalling Support For Linux Aims To Match Windows' ACPI/WMI Handling

Open-source developer Armin Wolf has been working most recently on marshalling support for the Windows Management Instrumentation (WMI) platform code within the Linux kernel. This WMI marshalling support is to better match the behavior of Microsoft Windows' WMI ACPI driver and ultimately to allow for better compatibility with some ACPI firmware and enhancing some WMI drivers...

Linux 6.19 Lands Fix For Seagate Barracuda HDD Taking Down The SATA Bus

It's not often getting to talk about hard drives on Phoronix these days, but there's an important fix merged to the Linux 6.19 kernel today ahead of Linux 6.19-rc2. If you happen to be using a Seagate ST2000DM008 Barracuda 2TB HDD, an important fix was merged to avoid it taking down the systems' SATA bus and/or potentially other issues...

Intel Readies Multi-Queue Support For Linux 7.0 As New Feature For Crescent Island

In addition to this week's drm-intel-next pull request to DRM-Next adding Nova Lake display support, a drm-xe-next pull request was also sent out on Friday that prepares a new multi-queue feature for Xe3P_XPC -- initially just the "Crescent Island" AI inference accelerator card. Plus other new features too for this Xe kernel driver in the upcoming Linux 7.0~6.20 kernel version...

Arch Linux's Main NVIDIA Driver Packages Now Using The Open Kernel Modules

With the Arch Linux packages for the NVIDIA official graphics driver moving to the now-stable NVIDIA 590 driver series that drops the GeForce GTX 900 and GTX 1000 series GPU support, Arch Linux users with those old Maxwell and Pascal graphics cards will need to transition to using the NVIDIA legacy driver packages from the Arch Linux AUR. Meanwhile for those on Turing and newer with the NVIDIA 590 driver will enjoy the open-source kernel modules by default being used...
