WebGPU as a next-gen web standard for accelerated graphics and compute is stepping closer to reality with the first public working drafts having been published...

Google used their Google I/O conference today to introduce the first beta of the upcoming Android 12 mobile operating system...

Mike Blumenkrantz working under contract for Valve on the Zink OpenGL-on-Vulkan implementation continues making remarkable progress on this Mesa code...

Two years after KernelShark 1.0 for visualizing the Linux kernel's "trace-cmd" tracing, KernelShark 2.0 has now been realized...

While last week the NVIDIA 460.80 Linux driver was released with adding support for the RTX 3050 / RTX 3050 Ti laptop GPUs, today the NVIDIA 465.31 Linux driver debuted for officially bringing these new Ampere GPUs to this newer driver branch...

For those wondering how GCC and LLVM Clang are competing when running on Intel's latest Rocket Lake processors, here are some GCC 11 vs. LLVM Clang 12 compiler benchmarks with the Core i9 11900K running from the newly-released Fedora Workstation 34 featuring these very latest compilers. The compiler benchmarks were carried out at multiple optimization levels on each compiler.

More than a decade ago when the open-source graphics driver stack was being modernized with kernel mode-setting and better handling the stack for OpenGL, composited desktops and the like, TTM (Translation Table Maps) was born for managing GPU video RAM by the kernel Direct Rendering Manager drivers. While Intel initially expressed interest in TTM, they ultimately decided to create GEM as the Graphics Execution Manager for handling their video memory management needs. Now in 2021 with Intel aggressively pursuing discrete graphics, they are working on TTM support...

AMD has issued its newest AMDVLK open-source Vulkan driver code drop today and with this update comes some new optimizations and improvements...

It's been a month and a half since AMD published a security analysis of their new Zen 3 "Predictive Store Forwarding" feature that while helping performance could theoretically lead to a new side-channel attack. While they published a Linux patch to allow disabling PSF if desired for increased security, to this day they remain in the works and have yet to be mainlined...

Back in 2007 Apple effectively acquired the open-source CUPS project and in 2017 then decided to no longer develop CUPS under the GPL but instead the Apache 2.0 license for this widely-used Unix/macOS/Linux print server. But then at the end of 2019 the CUPS lead developer left Apple and following that public development of CUPS seemingly halted. Fortunately, now there is a happy next chapter to the CUPS printing story...

The open-source Panfrost graphics driver stack that is now seeing support backed by Arm is going to see Mediatek MT8183 support with the upcoming Linux 5.14 kernel cycle this summer...

Google announced today the accepted projects/students for this year's Google Summer of Code. While for GSoC 2021 Google trimmed the length of this summer coding initiative and also cut the stipend amounts, there ended up being still a good turnout for this year with some interesting projects to be attempted...

Virglrenderer that is part of the open-source Linux effort to provide accelerated OpenGL to guest virtual machines has been enjoying some new micro-optimizations...

Going along with the recent releases of FreeBSD 13.0, DragonFlyBSD 6.0, and OpenBSD 6.9, NetBSD 9.2 is now available as the latest feature release of this BSD operating system...

Fedora 35 is looking to replace the unmaintained SDL 1.2 packages with using the sdl12-compat compatibility layer for better handling of vintage Linux games by this upcoming distribution release...

While we are sure to see only more AI accelerator drivers introduced to the Linux kernel over the coming years, the open-source driver situation for the Linux kernel is increasingly becoming a fragmented mess already and disagreements among kernel developers continue to be reignited over the mainlining process and the handling of these drivers...

With the new dav1d 0.9 AV1 decoder release bringing AVX2 Assembly for higher bit depth videos, the performance improvements are very pronounced with modern Intel and AMD systems...

Making some rounds this weekend is the "Lima" project. No, not to be confused with the open-source Arm Mali reverse-engineered project of the same name, but rather an effort to be like an unofficial "macOS subsystem for Linux."..

The second weekly release candidate is now available for Linux 5.13...

As written about a few days ago, the open-source Dav1d AV1 decoder has added AVX2 Assembly for higher bit depth decoding. Dav1d 0.9 is now available with this optimization and more...
