Limited Support For The AMD Pensando Elba SoC Might Finally Land Upstream In Linux 6.7
Limited Support For The AMD Pensando Elba SoC Might Finally Land Upstream In Linux 6.7
2 Minutes Ago - AMD - AMD Pensando Elba - Add A Comment

For a year and a half now Pensando has been working on enabling their Elba SoC support for the mainline Linux kernel - a process that coincidentally began just days after AMD announced it was acquiring Pensando. Over the past 18 months the AMD-Pensando Elba SoC enablement work has now been through 16 rounds of code review but still isn't over the finish line yet but some of the initial enablement code might finally land with Linux 6.7.

3 Hours Ago - Intel - PCP High Auto-Tuning - Add A Comment

Intel's open-source software engineers are known for many great performance optimizations to the Linux kernel. Over the years Intel has contributed countless performance optimizations to the kernel and related Linux components that have made significant improvements not only for Intel hardware but x86_64 as a whole and at times CPU architecture independent improvements. One of their newest performance optimizing patch series is around Per-CPU Pageset (PCP) high auto-tuning.

5 Hours Ago - Intel - No More Greco? - 1 Comment

Announced last year at the Intel Vision conference was the Habana Labs Gaudi2 and Greco AI hardware. Since then we've seen a lot of Linux kernel driver work happen for enabling the Gaudi2 second-generation training and inference AI processor while there hasn't been anything real in the way for Greco, which was the successor to the Goya AI processor. Now references to Habana Labs Greco are being removed from the driver.

A major update to OCRmyPDF is now available, the open-source project that can work on scanned PDFs and other PDF documents to add an optical character recognition (OCR) text layer to files for allowing them to be searched or copy-pasted. OCRmyPDF makes it a breeze in dealing with scanned PDF text files and now with OCRmyPDF v15 is even better.

Linux 6.7 Adding New Feature To Btrfs For The Steam Deck
Linux 6.7 Adding New Feature To Btrfs For The Steam Deck
25 September 03:08 PM EDT - Linux Storage - Btrfs Temp-FSID - 18 Comments

Queued up into the Btrfs file-system driver's "for-next" branch ahead of the Linux 6.7 cycle is the Temp-FSID (Same-FSID) feature that is being pursued for use by Valve's Steam Deck game console. The functionality is to overcome a limitation of allowing Btrfs to mount two different devices holding the same file-system image and therefore the same file-system ID.

Last month the Downfall CPU security vulnerability was disclosed that impacts various AVX/AVX-512 workloads. Now that there's been a few weeks for the Linux kernel code to settle around the mitigation and the latest Intel CPU microcode becoming more broadly available, here is a fresh look at the performance impact of the Downfall mitigation on affected AVX workloads.

Linux's Multi-Grain Timestamps Short-Lived: Removed From The Kernel After A Few Weeks
Linux's Multi-Grain Timestamps Short-Lived: Removed From The Kernel After A Few Weeks
24 September 06:54 AM EDT - Linux Storage - Multi-Grain Timestamps - 11 Comments

One of the new features merged for the Linux 6.6 kernel was multi-grained timestamps for the VFS layer and wiring it up for the EXT4, Btrfs, XFS, and Tmpfs file-systems. This alternative though to coarse-grained timestamps ended up exposing some problems and this week ahead of Linux 6.6-rc3, the feature has been stripped entirely from the kernel.

While Intel divested its storage business and Intel Optane was sadly discontinued, one of the interesting open-source software projects from its storage efforts has been DAOS, the Distributed Asynchronous Object Storage engine. Version 2.4 of the DAOS software-defined object store designed for high-speed storage was released this past week.

Cairo 1.18 was released today as the first major stable release to this 2D graphics library in five years. This vector-based graphics library is widely-used for a variety of purposes from GNOME's GTK toolkit to other apps making use of Cairo for targeting different back-ends from PDFs to OpenGL contexts. Mozilla Firefox, WebKit, Mono, and many other open-source projects are notable users of Cairo.

Prominent GNOME developer Christian Hergert announced he created a new terminal emulator that is twice as fast as the closest GPU-based renderer he's found yet so far on Linux, which was Alacritty. Unfortunately though he currently doesn't have any plans to develop this experimental speedy terminal emulator any further.

With Meteor Lake comes the introduction of the Versatile Processing Unit (VPU) that is now marketed by Intel as the Neural Processing Unit (NPU). Recent versions of the Linux kernel have the "IVPU" accelerator driver to support Meteor Lake's VPU/NPU while now a patch is pending to extend that support for next-generation Arrow Lake processors.

The Wayland Color Management protocol has been years in the making and is needed for a client to specify the color space and HDR metadata of a surface. This color management protocol is ultimately needed for getting high dynamic range (HDR) support working out well within Wayland environments. This week an initial merge request was opened for implementing the draft color management protocol with the Weston reference compositor.

AMDGPU LLVM Backend Begins Seeing Additions For New RDNA3 Refresh Instructions
21 September 06:39 AM EDT - Radeon - GFX1150 - Add A Comment

Over the summer the AMDGPU compiler back-end in upstream LLVM began with new targets for GFX1150 and GFX1151 which given all things known are likely the "RDNA3 Refresh" APUs. That work started out light with not much in the way of different code paths from the existing GFX11 support but we're beginning to see some new instructions added for the RDNA3 refresh graphics processors.
