[$] QBE 1.3: metaprogramming, performance, and cross-platform support
QBE , a compact compiler backend developed by Quentin Carbonneaux, is a lightweight alternative to larger compiler backends such as LLVM and GCC. Designed to be small enough for a single developer to understand, QBE uses a static single-assignment (SSA) intermediate representation (IR), supports the C ABI, and serves as the backend for projects such as Hare and the cproc C11 compiler. Frontends emit the textual form of QBE's IR directly; QBE then takes care of register allocation, optimization, and native-code generation, producing assembly for the target architecture.
Linux 7.3 Enabling Second Graphics Pipe For Modern AMD APUs
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...
Linux DT Patches Provide Very Basic Support For Apple M3 Pro / Max / Ultra
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...
HiZ Plane Optimization Merged For Intel Vulkan Linux Driver For Some Performance Benefit
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...
LLVM Clang Merges Initial Support For NVIDIA Rigel Core With Next-Gen Rosa CPU
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...

Graviton5 CPU Benchmarks: 30% Geo Mean Improvement Over Graviton4
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.
Claude desktop app for Linux enters beta
Anthropic has released a beta of its Claude desktop app for Linux, launching alongside an apt repo Ubuntu users can add for ongoing updates. According to the official docs, Claude desktop for Linux offers “the same Chat, Cowork, and Claude Code experience as macOS and Windows: parallel sessions, visual diff review, an integrated terminal and editor, and live app preview”. However, not all of the app’s features are yet available. The Linux beta lacks Computer Use, which lets Claude control apps directly, and voice dictation, both present on macOS and Windows. Anthropic says Computer Use support is coming to Linux […] You're reading Claude desktop app for Linux enters beta , a blog post from OMG! Ubuntu . Do not reproduce elsewhere without permission.

[$] Kitty chases the mouse
Kitty is a terminal emulator that runs on Linux, macOS, and the BSDs, which is notable for its speed and features such as image support and advanced font handling. It is under active development; a recent major release adds a new level of mouse support. Here, we will look at some of those features and show how the program can also be used as platform for text-based applications. Kitty is free software, released under the GPLv3.
Proposed Linux Patch For A Brief Delay To Match PCI Spec Will Hopefully Address Some Bugs
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...

Initial Patches Posted For Booting The Apple M4 On 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...
AMD Ryzen AI Halo Box RGB LED Driver Inches Closer To The Mainline Kernel
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...
