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.

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.

Intel Arrow Lake's NPU/VPU Very Similar To Meteor Lake - Linux Driver Patch Posted
23 September 06:48 AM EDT - Intel - Arrow Lake VPU/NPU Driver Support - 4 Comments

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.

23 September 06:36 AM EDT - Wayland - Wayland Color Management - 30 Comments

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.

Linux 6.5 With AMD P-State EPP Default Brings Performance & Power Efficiency Benefits For Ryzen Servers
21 September 10:30 AM EDT - Software - 17 Comments

With the new Linux 6.5 kernel stable series one of the many new features is defaulting to the AMD P-State driver with the EPP/active mode compared to the long-used default of the ACPI CPUFreq driver. As shown in various Phoronix articles this can help with the mobile/desktop performance with this new default change while this article is looking at the Ryzen for server benefits too.

AMDGPU LLVM Backend Begins Seeing Additions For New RDNA3 Refresh Instructions

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.

When it comes to Glibc HWCAPs for allowing the C library to load optimized libraries based upon the CPU features at run-time, it's mostly been focused on the x86_64 world for targeting higher x86-64 levels or being able to load optimized libraries for systems with AVX support. Loongson though has now contributed initial LoongArch HWCAPs support.
