Intel Posts New Linux Patches Looking To Re-Enable ENQCMD Ahead Of Sapphire Rapids

While Intel is normally quite good with their new hardware support being in good shape well ahead of launch, their new code for supporting the ENQCMD functionality for the Data Streaming Accelerator (DSA) with Xeon "Sapphire Rapids" has been an exception. This summer the mainline Linux kernel disabled ENQCMD support since the code was "broken beyond repair" while now Intel engineers have sent out a new series looking to get it re-enabled.

AMD Continues CRIU Work To Checkpoint/Restore ROCm Compute Workloads

Earlier this year AMD went public with prototyping CRIU support for Radeon GPUs around ROCm to be able to checkpoint/freeze running compute workloads and to then restore them at a later point. This CRIU focus is driven by their big accelerator needs and forthcoming supercomputers for migrating workloads particularly within containers. AMD continues working on CRIU support for GPUs and last week provided an update on the project.

AMD + Valve Focusing On P-State / CPPC Driver With Schedutil For Better Linux Efficiency

As reported at the start of August, AMD and Valve have been working on Linux CPU performance/frequency scaling improvements with the Steam Deck being one of the leading motivators. As speculated at that time, their work would likely revolve around use of ACPI CPPC found with Zen 2 CPUs and newer. Published last week was that AMD P-State driver for Linux systems indeed now leveraging CPPC information. AMD formally presented this new driver yesterday at XDC2021.

The Current State Of Intel Discrete Graphics On Linux: Almost "Fully Functional"

Along with bringing up DG2/Alchemist graphics card support on Linux, Intel engineers have been working to square away their support for the DG1 developer graphics card. This week thanks to XDC2021 is a fresh status update about what is working with this initial Intel graphics card on their open-source driver and what remains in the works.

The Increasing Importance Of ACPI Platform Profiles With Today's Throttle-Happy Hardware

As covered several times going back to the end of last year, ACPI Platform Profile support has materialized in recent versions of the Linux kernel for the core infrastructure and implementations that work with the latest laptops from the likes of Dell, Lenovo, ASUS, and HP. This platform profile support is becoming increasingly important with expressing your power/cooling/performance preference so that your laptop behaves as one would expect.

X.Org Could Use More Help Improving & Addressing Its Security

Those reading Phoronix over the years likely know the X.Org Server has had an increasing number of vulnerabilities come to light in recent times and statements by security researchers like the security being even worse than it looks. Given the age of the X.Org/X11 codebase and many components being rather unmaintained these days, the security situation isn't that great combined with a lack of manpower. The security topic was under the spotlight today at the XDC2021 conference.

Running Linux 5.15-rc1 Causing A New Slowdown... Here's A Look

As usual when the Linux 5.15 merge window began wrapping up, I set out to dive into its performance to see what is in store for this next version of the kernel and whether there was any regressions or other performance changes worth noting. Linux 5.15 overall has been in good shape for the "-rc1" state except noticing that code compilation workloads were taking longer on multiple Linux 5.15-rc1-running systems than Linux 5.14 or prior. Seeing it across multiple systems and a very real-world regression, it was worth bisecting and looking closer so here are the details.

Google Is Successfully Using The Open-Source Qualcomm GL/VLK Drivers On Chromebooks

It's been known that Google has been using the open-source "MSM" DRM/KMS driver on Qualcomm-powered devices that originally started out as a reverse-engineered driver project separate from the company. Now it's also been confirmed how Google is successfully using the open-source Mesa Freedreno OpenGL and TURNIP Vulkan drivers on Qualcomm-powered Chromebooks too.
