Open-sourced back in January was the Yandex Perforator as a new software project for uncovering code inefficiencies and potentially "save billions of dollars" in expenses. Perforator has continued evolving since its open-source announcement and out today is Perforator 0.0.5 as the latest milestone...

The AMD BC-250 is a crypto mining GPU launched by AMD back during the Bitcoin mining craze when it was profitable using GPUs for mining. At its heart is a Navi "RDNA1" GPU similar to the APU found within the Sony PlayStation 5. The AMD BC-250 can be found used these days for $50~100 USD and with the latest open-source Mesa graphics driver code for Linux systems can now be used with the Vulkan API for graphics/gaming...

In addition to mapping the Direct3D graphics API to Vulkan, Wine developers are working on mapping the Direct3D video acceleration APIs to work atop the Vulkan Video API...

While AMD hasn't released an updated Windows driver for the Radeon R9 290 "Hawaii" GPUs since 2022 for Windows 10, over in the Linux/open-source space the driver support continues. It will hopefully continue reliably too now that the Mesa RADV continuous integration (CI) has added driver testing with an old Hawaii GPU...

Going back nearly one year Intel has been working on Linux driver support for a new adaptive sharpening filter with Lunar Lake graphics.

The Redox OS open-source operating system written from scratch in the Rust programming language is continuing to enjoy nice progress in 2025 on its goals. The Redox OS project has published their February 2025 status update that highlights achievements made over the past month...

V tomto článku začneme jednoduchými obvody, postavíme digitální budík a nakonec připravíme periferní zařízení pro náš budoucí počítač: VGA výstup, vstup z klávesnice PS/2 a sériový port.

Popíšeme si zbylé instrukce pro provádění numerických výpočtů. Také se zmíníme o instrukci pro porovnání prvků vektorů, která má celkem osm různých variant. A nezapomeneme ani na problematiku nekonečných hodnot a hodnot NaN.

SiFive recently sent over their new HiFive Premier P550 developer board and as part of that fresh RISC-V CPU testing I've also been re-testing the prior SiFive HiFive Unmatched developer board from 2020~2021 for reference. Out of curiosity, I've carried out some tests using the HiFive Unmatched to look at how the Ubuntu Linus RISC-V performance has evolved from Ubuntu 21.04 when I first tested that RISC-V quad-core developer board, Ubuntu 22.04 LTS, and now the latest Ubuntu 24.04 LTS packages.

Godot 4.4 is out as stable today for serving as the newest feature release to this leading open-source, cross-platform 2D/3D game engine...

Vývojári distribúcie Linux Mint uverejnili ďalšiu súhrnnú správu s prehľadom minulomesačných noviniek z vývoja. Jednou zo zaujímavých noviniek je pripravovaná zmena dizajnu hlavného menu aplikácií.

Back in December Linux kernel patches were posted by a Meta engineer for making use of the AMD INVLPGB instruction found with Zen 3 and newer processors. The Linux kernel would use INVLPGB for invalidating TLB entries for a range of pages with broadcast. After these patches went through 14 rounds of review since December, it looks like this AMD broadcast TLB invalidation support is now ready for the mainline Linux kernel!..

Raspberry Pi has been on a spree lately with many new product launches such as the Raspberry Pi 500, Raspberry Pi Monitor, Raspberry Pi 5 16GB, and Compute Module 5 in the past few months. Today the company announced an expansion of their offerings in the Compute Module 4 line-up...

Last September the USB Implementers Forum quietly published an update to the USB 2.0 specification... The Embedded USB2 Version 2.0 "eUSB2V2" supplement to provide for better performance with significantly higher data rates to USB 2.0 while maintaining the low-voltage electrical interface...

Open-sourced back in 2019 was the OpenPOWER Microwatt as an open-source, soft processor core of Power ISA 3.0 and intended for use on FPGA boards and then there was seemingly short-lived work to fabricate a Microwatt chip and Microwatt also found its way for use within a BMC implementation. Linux 5.14 added support for this soft CPU core while the upcoming Linux 6.15 cycle is set to introduce SMP support for Microwatt...

The newest upstream-focused work around AMD SEV for Secure Encrypted Virtualization with EPYC server processors is a set of patches to better optimize cache flushing...
