A new software project covered on Phoronix last year was SCALE for natively compiling CUDA applications for AMD GPUs. This "clean room" implementation of CUDA building off the open-source LLVM codebase continues going strong and out this week is SCALE 1.3 with more features and hardware support for compiling CUDA software for AMD GPU execution...

Nová verzia stabilnej edície linuxovej distribúcie OpenMandriva Lx 6.0 aktualizuje väčšinu softvérových balíčkov. Vývojári zároveň oznámili vydanie samostatných obrazov OpenMandrivy pre servery.

Completely separate from the big performance regression I noted earlier this week for the Linux 6.15 Git kernel and fixed yesterday in the upstream codebase, another significant performance issue was also uncovered and fixed this week in Linux 6.15 Git...

New Linux kernel patches have been posted adding the necessary Device Tree files so that Linux is able to boot on the Qualcomm Snapdragon X1 powered Dell Inspiron 14 Plus laptop...

Mesa has supported on-disk shader cache for years to help speed-up game load times and overall system efficiencies. They had shifted from a multi-file cache layout to a single file cache for greater space savings. Steam also added support for the single-file cache. But now upstream Mesa is shifting back from the single-file cache default to the multi-file cache over performance issues...

At the end of last year the upstreaming efforts began for a Raspberry Pi HEVC decoder driver for getting H.265/HEVC accelerated decode working on the Raspberry Pi 4 and Raspberry Pi 5 single-board computers with the mainline kernel. Nearly a half-year later that effort is still ongoing but yesterday brought the third iteration of this driver...

The latest bit of hardware enablement coming out of Asahi Linux and queued for introduction in the mainline kernel the next cycle is PCI Express (PCIe) support for the Apple M2 Pro SoC...

AMD has published as open-source their "GPU-IOV Module" used for virtualization with Instinct accelerators. It's also reported on their roadmap for bringing virtualization support to their client (Radeon) discrete GPUs...

Z předchozích dílů máme připravený procesor MB5016 ve formě VHDL entity. Nyní přidáme další potřebné komponenty (paměť, řadiče periferií a ladicí rozhraní) a postavíme celý počítač.

Ukázali jsme si konstrukci, trénink a validaci neuronových sítí s využitím knihovny PyTorch. Zbývá nám ovšem seznámit se blíže s konceptem afinních transformací a aktivačních funkcí. Právě to je téma dnešního článku.

OpenMandriva Lx 6.0 Rock is now available with the KDE Plasma 6 desktop shipping by default while still offering both Wayland and X11 session options. There is also now an official server edition of OpenMandriva...

The Linux 6.15 kernel has just merged a fix for the big performance regression I spotlighted yesterday on Phoronix with a huge hit to the Nginx HTTPS web server performance that could see a 3x regression from the in-development Linux 6.15 kernel code. It turns out other workloads/applications also were negatively impacted by this regression. While a stumper at first even with the bisected commit, the issue was luckily resolved very quickly.

Mesa 25.1-rc2 is now available for testing as the newest weekly test version of this collection of OpenGL and Vulkan drivers. Mesa 25.1 continues working its way toward a stable release in May...

Earlier this month Canonical announced Ubuntu Linux support for the Orange Pi RV2 as a low-cost RISC-V developer board. The Orange Pi RV2 with eight RISC-V cores and 8GB of RAM costs just around $64 USD. The price point and specs were interesting that I ordered one and have been running performance benchmarks on it since for seeing how capable this is as finally an interesting, low-cost and readily available RISC-V board.

The newest open-source Linux driver being worked on by AMD engineers is a Remote Direct Memory Access (RDMA) solution for their Pensando networking hardware...

Back in March some ideas were talked about by Canonical engineers for Ubuntu Linux to move to Rust Coreutils and other Rust-written system components. Some of this is likely to materialize for the Ubuntu 25.10 release due out in October to allow for sufficient testing ahead of the all important Ubuntu 26.04 LTS release next year. Today the more solidified plans have been laid out for moving to the Rust Coreutils as a replacement to GNU Coreutils with Ubuntu 25.10...

Following a lot of work in this direction toward the end goal of removing GNOME X11 support, this milestone may finally be acheived for the Fedora 43 cycle due out by the end of the year. A change proposal has been filed for removing the GNOME X11 packages in the repository and in turn making the GNOME desktop Wayland-only on Fedora Linux...

One of the biggest surprises of last year was finding out that VMware has been working on shifting VMware Workstation from proprietary code to building atop the upstream KVM code within the Linux kernel. Following the initial patches from last October, an updated patch series was sent out on the Linux kernel mailing list yesterday for working on this transition...

The Google Pixel 4a smartphones launched in mid-2020 and now in mid-2025 it looks like we might finally be close to seeing mainline kernel support for the Pixel 4a devices and other hardware making use of Qualcomm Snapdragon 730/730G/732G SoCs...
