Svobodný software

Sonda do světa otevřeného softwaru. Dnes si představíme offline komunitní navigaci, vyzkoušíme WebGPU emulátor terminálu, dáme si dohromady svoje úkoly a řekneme si o asistentovi pro korektury.

The upcoming Linux 6.17 kernel is going to be an especially nice release for users of modern Intel graphics hardware on Linux. The very latest feature being enabled for this next Linux kernel version is SR-IOV for Battlemage GPUs to vastly enhance the Intel Linux graphics experience in virtualized environments...

Blender 4.5 is now officially available today as the newest feature release and one that is a Long Term Support (LTS) for this popular, cross-platform 3D modeling software...

One month ago there was the report on Phoronix of the Broadcom "BNGE" open-source driver being published for forthcoming BCM5770X networking chipsets. That new Broadcom BNGE driver is now set to be introduced in the upcoming Linux 6.17 kernel for supporting the new Broadcom wired networking hardware at up to 800 Gigabit speeds...

The LLVM 21 compiler stack was branched today as release preparations get underway for shipping this next half-year compiler release as stable in late August or early September. In turn that now opens up LLVM 22 for development...

Last month patches were posted for porting the Linux kernel's "gconfig" graphical kernel configuration utility from GTK2 to GTK3. It looks like those patches for the GTK3-ified gconfig are ready for upstreaming come Linux 6.17...

While the Intel Media SDK with VA-API has long supported accelerated video decoding, the latest Mesa 25.2 development code has now landed support for AV1 decoding using the Vulkan Video API with the Intel ANV driver for Xe2 Battlemage / Lunar Lake graphics and Gfx125 Xe graphics too...

The latest round of cost-cutting at Intel seems to be having a larger impact on their software engineering efforts than some of their previous rounds of layoffs. In addition to a prominent Linux kernel developer veteran leaving Intel last week where he worked for the past 14 years and responsible for many great upstream improvements, other Intel software engineers working on their Linux/open-source affairs have also been departing. In just the latest instance, one of the upstream Intel Linux kernel drivers is now "orphaned" due to the developer departing and no one experienced left to maintain the code...

Merged yesterday to the latest development code for the LibreOffice open-source office suite is now recognizing Bitcoin "BTC" as a supported currency for use within the Calc spreadsheet program and elsewhere within this cross-platform free software office suite...

As part of work going back to 2019, an engineer on Google's Chromium OS team submitted an updated proposal on Monday for seeking to standardize the haptic touchpad support within the Linux kernel...

Making it into the RADV Vulkan driver ahead of this week's Mesa 25.2 feature freeze is experimental support for the VK_EXT_host_image_copy extension. The Vulkan host image copy extension was worked on by Valve and others for letting applications/games copy data between the host memory and images on the host processor without having to first stage via a GPU-accessible buffer...

The LTTng tracing toolkit is twenty years old this year and it's seen significant adoption by different hyperscalers and other notable organizations like IBM and Sony and Siemens beyond basic end-users and administrators for system tracing/debugging. While having many successes over the past two decades, the kernel modules remain outside of the kernel tree. Even with around four different upstreaming attempts to get the LTTng code into the mainline kernel, it still has not happened. A fifth attempt began today but still looks like it could be an uphill battle...

Ukážeme si praktické použití algoritmu CORDIC. Prozatím budou pro jednoduchost výpočty prováděny s FP hodnotami; příště provedeme přepis pro hodnoty s pevnou řádovou tečkou.

With the upcoming Linux 6.17 kernel the Intel Xe kernel graphics driver is enabling Panther Lake graphics out-of-the-box. Now going along with that Linux 6.17+ support out-of-the-box, the Mesa OpenGL and Vulkan user-space drivers are also ready to declare their Xe3 Panther Lake graphics support by default...

Posted today to the Linux kernel mailing list are a set of nine patches for bringing up support for the Qualcomm Snapdragon X Elite/Plus powered Microsoft Surface Pro 11 2-in-1 laptop...

A number of Phoronix readers have been interested in seeing some fresh benchmarks of Mesa's NVK Vulkan driver in providing open-source Vulkan API support on NVIDIA GeForce graphics cards as well as the modern OpenGL approach of using Zink for layering OpenGL atop Vulkan. Here are some fresh benchmarks using the very latest Mesa 25.2 code for NVK on the latest upstream stable Linux kernel compared to the NVIDIA R575 official Linux graphics driver stack.

Merged today into the upstream GNU C Library code ahead of next month's Glibc 2.42 release is support for SFrame stack tracing with ELF binaries on x86 and AArch64 architectures...

New feature patches posted for review today on the Linux kernel mailing list are working to implement the NVMe specification's Controller Data Queue (CDQ) functionality within the NVMe storage driver...

In addition to last minute feature work on the latest AMD RDNA4 graphics cards ahead of the Mesa 25.2 code branching, there's also some new fixes going into Mesa for the open-source Radeon driver code... Coming in this Monday morning by surprise are some fixes for the Radeon HD 2000/3000 series approaching two decades old as well as a fix for the Radeon HD 4000 graphics processors...

Ahead of the Mesa 25.2 code branching / feature freeze expected later this week, last minute feature additions and other changes continue landing in the codebase for these open-source OpenGL and Vulkan drivers. One of the additions today worth mentioning are continued Vulkan Video improvements for AMD Radeon graphics...
