Google engineers earlier this year detailed an AMD CPU microcode signature verification vulnerability. For local users with administration/root privileges, it could lead to loading malicious CPU microcode patches on the system. Initially AMD Zen 1 through Zen 4 were affected but the Google security engineers since discovered Zen 5 also could be impacted. BIOS updates are rolling out to address this signature verification issue while the Linux kernel is also being patched for microcode protections on Zen 5...

A change merged yesterday to the Intel Mesa graphics driver code lessens a restriction around the amount of system memory (RAM) that can be used by processes for the Vulkan system heap. This will allow more games/apps to work with the Intel integrated graphics that previously exceeded the driver-enforced limits but at the risk of running into broader out-of-memory behavior if under too much memory pressure...

Gzip 1.14 released earlier today as the first new release to this widely-used file compression format on Linux systems and other platforms...

While there are efforts underway to effectively kill the Linux virtual terminal "VT" console by punting the functionality off to user-space, it's not dead yet and a new patch series out on Wednesday aims to enhance the modern Unicode handling by the Linux VT...

Mesa's Radeon Vulkan driver "RADV" is now exposing its emulated ray-tracing support by default for older AMD Radeon GPUs even without any form of hardware-accelerated ray-tracing in order to run the new Indiana Jones game. It turns out even the emulated RT mode is fast enough to allow various older AMD Radeon graphics cards to be playable with this title...

Long before the likes of DXVK for Direct3D APIs implemented atop Vulkan, and even before the Vulkan API was conceived, there's been Gallium Nine as a Direct3D 9 state tracker implementation for Gallium3D. Gallium Nine showed promise in its early days for speeding up D3D9 Windows games running atop Wine on Linux. But with DXVK working out better these days and Gallium Nine no longer being maintained in recent times, it's now deprecated and set for removal later this year...

Submitted today via DRM-Misc-Next for queuing in DRM-Next until the Linux 6.16 merge window in June is the Asahi driver user-space API "UAPI" header. This is the user-space API intended for the Asahi kernel graphics driver for supporting the Apple M-Series graphics hardware under Linux. But due to being written in the Rust programming language and various kernel abstractions not yet ready among other obstacles, only the user-space API header is set to be added and not yet introducing the actual Direct Rendering Manager driver...

Co se děje v procesoru, když vykonává strojový kód? Jak se načítají, dekódují a provádějí jednotlivé instrukce? Jak procesor přistupuje k paměti? Co se stane, když přijde přerušení?

Ukázali jsme si tvorbu MCP klientů i serverů v Pythonu s využitím oficiální MCP knihovny, zatímco dnes se zaměříme na jazyk Go, pro který oficiální knihovna prozatím není k dispozici.

Last year TUXEDO Computers shared that they were developing an ARM Linux notebook powered by the Qualcomm Snapdragon X Elite. They hoped to have the Snapdragon X Elite Linux laptop shipping by Christmas 2024, but that didn't pan out. TUXEDO Computers has now provided a status update regarding this ARM Linux notebook effort...

Framework Computer has been working on bringing the Framework 12 to market as a new, smaller and convertible laptop while retaining the upgradeable aspects that users have come to love from the company. Today the company announced the pre-orders are open and the first Framework Laptop 12 devices will be shipping in June...

Not to be confused with the AMDXDNA accelerator driver that was mainlined just with the Linux 6.14 kernel, AMD Linux engineers are now working on "AMDPK" as a new accelerator driver for their upcoming PKI Accelerator engines...

AMD announced today they will be hosting a virtual "Advancing AI 2025" event in mid-June where they will talk about their next-gen AMD Instinct accelerators while of much interest to many Phoronix readers is an update on the ROCm open-source software...

OpenSSH 10.0 is now available for this widely-used SSH client/server implementation. There are a number of changes to find with OpenSSH 10.0 including better protections against possible attacks by future quantum computers...

As part of the announcements coming out today from Google Cloud Next 2025, the embargo has now lifted on the new Google Cloud C4D VMs. Powered by AMD EPYC 9005 "Turin" processors, the new C4D instances deliver incredibly high performance and can scale up to 384 vCPUs with 3TB of RAM. For web servers, databases, CPU-based machine learning, and other workloads, the new Google C4D instances deliver incredible uplift compared to the prior-gen C3D instances. Here are some of the first public, independent benchmarks of Google's new C4D family.

The Ubuntu 25.04 release shipping this month will now feature JPEG-XL image format support out-of-the-box...

Well known open-source AMD Mesa developer Marek Olšák has landed his most recent conquest: implementing support for 16-bit NIR types within the RadeonSI Gallium3D driver along with the LLVM and ACO compiler back-ends...

As a sooner than expected follow-up to the recent news article around Apple M1 / M2 / M3 core support for the GCC compiler, that code has now been successfully merged in time for the upcoming GCC 15 stable compiler release...

Merged back in Linux 6.9 was AMD Preferred Core support for Linux for the concept of "preferred cores" with newer Zen processors that are communicated via ACPI CPPC for select cores able to reach a higher maximum frequency or should otherwise be preferred over other cores on the system in the name of maximizing performance. That was a nice step forward for better handling newer Ryzen processors on Linux and matching functionality that had already been working under Microsoft Windows. Of focus more recently has been working on enabling more dynamic Preferred Core support for where the priority of the preferred cores may change at run-time...

Yesterday brought the newest update to Microsoft's in-house Linux distribution, Azure Linux. The Azure Linux 3.0.20250402 brought many package updates mostly in the name of shipping security fixes plus brought new instructions on making use of the AMD graphics driver stack under this Microsoft Linux distribution along with various other updates...
