AMD Extending DWARF To Better Handle GPU Debugging, Continues Collaborating With GCC & LLVM

In addition to AMD's increasing Linux kernel contributions, they are also contributing more improvements in user-space too thanks to their super-computing wins and other big enterprise deployments that are Linux-based. One of the areas talked about this week at the Linux Plumbers Conference with the GNU Tools track is how they are working to extend the DWARF debug format to better handle GPU debugging.

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.

CUPS 2.4 Coming Next Month, CUPS 2.5 + CUPS 3.0 Already In Planning

An Open Printing micro-conference took place today during the Linux Plumbers Conference 2021 week. While it's hard to get excited about printers in 2021, it is exciting the renewed effort around CUPS with it now being back to effectively led by the community and CUPS founder Michael Sweet who left Apple. CUPS 2.4 is coming as the first feature release in quite a while and then CUPS 2.5 followed by CUPS 3.0 are already being talked about with features being discussed.

Phoronix Ad-Free/Premium Special For Oktoberfest 2021

While Oktoberfest was once again cancelled due to the COVID-19 pandemic (then again, due to the state of the ad industry / ad-block users we haven't had any European meet-up / open-source gathering in years), the wiesn would have kicked off this past weekend. So as is tradition, there is the Phoronix Premium Oktoberfest sale where you can join the ad-free service as a reduced rate. If you enjoy the daily, original Linux and open-source content on Phoronix with plenty of benchmarking, you can do so at a reduced rate.

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 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.
