Sent out today was this week's round of x86 (x86_64) fixes ahead of the Linux 7.2-rc3 kernel test candidate due out on Sunday.

Stanford researchers have been developing Lightweight Fault Isolation "LFI" compiler passes and targets for LLVM as a means of efficient, native code sandboxing. The AArch64 LFI target was previously upstreamed while this week the x86/x86_64 LFI target was also upstreamed for this means of in-process sandboxing.

KDE developers continue to be very busy this summer landing more features for the upcoming Plasma 6.8 desktop.

A change upstreamed to Mesa by an Arm engineer now enables the Panfrost Gallium3D driver for Arm Mali graphics to work with the Rusticl driver by default.

Wine 11.13 is out today as the newest bi-weekly development release for this open-source software enabling support for running Windows games and applications on Linux.

System76 developers have for the past number of weeks been working on developing a "frosted glass" appearance for the COSMIC desktop environment featured on their Pop!_OS Linux distribution. For Pop!_OS users this frosted glass feature is now available and will become more widespread for other Linux distributions once the next COSMIC release is formally tagged.

With KDE Plasma 6.7 now having seen a few point releases to further polish this last version with X11 support ahead of Plasma 6.8 going Wayland-only, here are some NVIDIA Linux gaming benchmarks between the X11 and Wayland sessions on Plasma 6.7.2 using the popular Arch Linux based CachyOS.

AMD on Thursday sent out another round of AMDGPU kernel graphics driver and AMDKFD kernel compute driver updates to DRM-Next of new feature material ahead of the Linux 7.3 merge window.

Upstreamed for the Linux 7.2 kernel was initial support for booting Linux on the Apple M3 SoC devices. But just the barebones suppport for booting with not yet any accelerated graphics or other typical function needed for daily use of M3 Apple devices on Linux, just booting to a console. Now this work is complemented by additional Device Tree patches for also booting M3 Pro / Max / Ultra devices on Linux.

After two years being on the TODO list for a possible performance optimization, the Intel open-source "ANV" Vulkan driver has now merged an HiZ plane optimization that can yield up to a few percent frame-rate improvement for Linux gaming/graphics on newer Intel integrated and discrete graphics hardware.

Earlier this week NVIDIA confirmed some basic details around their next-gen Rosa CPU that succeeds Vera. Among the public confirmation was that it will feature a "Rigel" Armv9.2-A core iterating on their Olympus core design. With the basic details published, NVIDIA immediately introduced Rigel core support into the GCC compiler. Now they have also upstreamed their initial Rigel core enablement into the LLVM Clang compiler.

Released this morning was Intel's newest version of Intel-Scaler-vLLM as their Docker-based solution providing an optimized vLLM stack for execution on Intel Arc (Pro) graphics hardware.

For those that enjoy the daily flow of original open-source/Linux news on Phoronix along with all of the original Linux hardware reviews and performance benchmarking, but haven't yet subscribed to Phoronix Premium to help keep the site going after 22 years, the summer sale ends tonight.

Today's batch of AMDGPU Display Code "DC" updates bring a few noteworthy items for benefiting modern hardware under Linux.

After originally announcing Graviton5 last December, recently AWS finally made the M9g and M9gd instances generally available as the first featuring these new in-house ARM server processors for the EC2 cloud. Graviton5 makes use of Arm Neoverse-V3 cores compared to Neoverse-V2 with Graviton4, support up to 192 cores, and feature a higher 3.3GHz clock speed compared to 2.8GHz on the prior-generation Graviton CPUs. Here is an initial look at how the Graviton5 processor performs over Graviton4.

In addition to Weston 16 nearing release and its release candidate out today, the Wayland 1.26 release candidate was just issued with a few notable changes on top of the more typical bug fixing.

Going back to February there was a bug report around the xHCI controller dieing on resume from s2idle when using an AMD Ryzen AI Max+ "Strix Halo" Framework Desktop. In turn all USB devices behind the xHCI controller are lost on resume, but unbinding and binding the driver can restore the functionality without a reboot. After months of back and forth communication, it looks like a solution has been figured out and comes down to a nuance of the PCI spec with needing a brief wait.

Newer Lenovo ThinkPad systems feature a security feature called USB-C Security Restricted Mode that is in the process of being wired up for reporting under Linux.

With the Linux 7.2 kernel there is initial support for booting the Apple M3 SoC on Linux but it's not yet functional for end users with just booting to a simple console. There are now Device Tree files posted for booting the Apple M4 on Linux but also not yet useful for any typical Apple Mac/MacBook usage on Linux.

The AMD Ryzen AI Halo mini PC powered by Ryzen AI Max+ "Strix Halo" began shipping this week. It features very nice Linux support out-of-the-box with the Debian-based Ryzen AI Developer Platform operating system. For those wishing to run their own x86_64 Linux distribution, one of the only caveats in the Linux support is quite small... No mainline kernel support yet for controlled the RGB LED light strip on the driver. But that driver is coming and will hopefully be mainlined soon.
