Canonical Gets Flutter Up And Running On RISC-V For Ubuntu

20 novembre 2025 à 22:04
Canonical has been bullish on RISC-V with Ubuntu being one of the most common Linux distributions endorsed by RISC-V board vendors. Canonical also has been bullish on the Flutter toolkit for crafting their desktop installer UI and other modern UI/app interfaces. But these two together haven't panned out with Flutter not currently supporting RISC-V. Canonical has submitted pull requests now for enabling RISC-V support with Flutter...

Updated Steam Runtime Switches To Debian 13 Libraries, SDL2 Using Compatibility Layer

20 novembre 2025 à 18:34
An updated version of the Steam Linux Runtime 4 branch was rolled out that has now shifted from Debian 11 to Debian 13 libraries for some significant upgrades. In the process more libraries have gone x86_64 only in foregoing the i386 builds. In addition, the SDL 2 library support for the Steam Runtime is now provided by sdl2-compat as the compatibility layer for SDL2 atop SDL3...

Linux 6.19 Slated To Land "mm/cid" Rewrite That Has Very Positive Performance Potential

20 novembre 2025 à 16:44
A set of Linux kernel patches posted back in October for rewriting the kernel's memory-mapped concurrency ID code for some nice performance wins looks like it will land for Linux 6.19. This is the code that prominent Intel engineer Thomas Gleixner found to yield up to an 18% improvement for the PostgreSQL database. My testing of this "mm/cid" code has also shown some nice performance wins too...

Rusticl Has Turned Out Remarkably Well For Open-Source OpenCL For Mesa Drivers

20 novembre 2025 à 12:27
Rusticl as a modern OpenCL implementation for Mesa Gallium3D drivers has turned out remarkably well. Rusticl performance has evolved quite well for this Rust-based OpenCL driver and it continues tacking on new features / OpenCL extensions as well as working gracefully with more Mesa drivers. Rusticl lead developer Karol Herbst presented on some of the recent accomplishments for this driver back at XDC2025...

Rust-Based Arm GPU Kernel Driver "Tyr" Begins Running GNOME & Basic Games

20 novembre 2025 à 00:38
Initially upstreamed into the Linux 6.18 kernel is Tyr as a Rust-based GPU kernel driver for Arm Mali hardware. This is in effect a Rust alternative to the Panthor DRM kernel driver for newer Arm Mali GPUs with the Command Stream Firmware (CSF). With the latest development code for Tyr, it's moved onto running the GNOME desktop and basic games like SuperTuxKart...

AMD Begins Posting Open-Source Linux Patches For Their Next-Gen GPU IP

19 novembre 2025 à 16:31
Beginning yesterday and continuing today are several patch series beginning to lay the foundation in the AMDGPU kernel graphics driver for enabling some next-generation graphics IP. Due to the AMD graphics driver block by block enablement strategy and IP-based discovery adopted by their driver over the past few years, it's not clear what this new hardware enablement is for whether it's RDNA5 / UDNA or some RDNA4 refresh. In any event, the Linux driver enablement has begun...

Qualcomm Upstreaming Initial GPU Support For Snapdragon X2 Elite In Linux 6.19

19 novembre 2025 à 15:25
Back in September the Qualcomm X2 Elite SoCs were announced for next-gen Windows 11 on Arm laptops. Since then some initial X2 Elite enablement patches for the Linux kernel have arrived and for the upcoming Linux 6.19 kernel more of that work will reach mainline. Excitingly, Linux 6.19 is now bringing GPU and display support for the Adreno X2-85 found within the Snapdragon X2 Elite SoC...

AMD Continues Working On Xen GPU Virtualization Features - "The Best Is Yet To Come"

19 novembre 2025 à 12:42
When it comes to GPU virtualization we have seen AMD engineers carry out a lot of work in recent years around the Xen hypervisor even when it hasn't seen as much interest from other vendors. We found out that much of their interest in Xen for GPU virtualization is due to automotive / in-vehicle infotainment demands and it remains that way. They continue cooking some new features and they say "the best is yet to come" in a new presentation on their Xen virtualization efforts...

More NVIDIA Nova Enablement For Linux 6.19 With Other Rust Graphics Driver Code

19 novembre 2025 à 12:29
Alice Ryhl of Google sent out the main set of Rust language code changes for the Direct Rendering Manager (DRM) graphics/display driver subsystem ahead of Linux 6.19. Notable is continued DRM core infrastructure work for Rust plus the open-source NVIDIA "Nova" driver continues taking shape albeit isn't yet ready for end-user usage...

GCC 16 Compiler Now Ready For AVX10.2 & APX With Intel Nova Lake

19 novembre 2025 à 12:16
Intel's ISA documentation was updated last week to confirm Nova Lake processors will support AVX10.2 and APX extensions after they were not officially acknowledged in prior versions of the spec and the initial open-source compiler enablement with -march=novalake also left them without those prominent ISA capabilities. Following that documentation update, a few days ago LLVM Clang updated their Nova Lake compiler support for the new ISA capabilities and now the GCC compiler has received similar treatment...

Vulkan SER Showing Up To ~47% Performance Improvement For Ray-Tracing

19 novembre 2025 à 02:40
Last week's Vulkan 1.4.333 brought a new ray-tracing extension with VK_EXT_ray_tracing_invocation_reorder that was derived from a prior NVIDIA vendor extension (VK_NV_ray_tracing_invocation_reorder). This new extension for Shader Execution Reordering "SER" is showing to deliver some nice performance potential for Vulkan ray-tracing performance...
