An Intel engineer has implemented compute-based transcoding support to the DXT5 texture format as part of S3TC texture compression. This new path yields a 56% decrease in upload time for a texture upload micro-benchmark when tested on an Intel Ice Lake system with the Iris Gallium3D driver...
This week Intel released Embree 4.0 as the newest version of their open-source, high performance ray-tracing library. While the headline feature is now having support for GPU acceleration with SYCL to take advantage of Arc Graphics and other GPU hardware with SYCL support, for those that have long been using Embree on CPUs its performance has also improved. Here are some initial CPU-based benchmarks I did this week on Embree 4.0 with Intel's new 4th Gen Xeon Scalable "Sapphire Rapids" processors.
Apple introduced the Touch Bar to their MacBook Pro laptops a half-decade ago as a dynamic touchscreen to replace the function keys on the keyboard. While some MacBook Pro models have already dropped the Touch Bar for not catching on, some community developers in the open-source Linux community continue work on enabling the functionality for the upstream Linux kernel...
After being in development for nearly one year , Zstd 1.5.4 has been released with many "significant performance improvements across multiple scenarios" for this increasingly-used data compression algorithm...
Red Hat engineers have been working on a new web-based user-interface for Fedora's installer for more than on year now and it's been worked into good shape while still not at feature parity to the Anaconda installer with its GTK interface. Martin Kolman presented at FOSDEM last weekend on Fedora's new installer UI to offer insight into their motives for making it web-based and what work remains...
The Gentoo project has provided a 2022 recap that highlights all of their interesting milestones achieved over the past year for this traditionally source-based Linux distribution that has long been popular with enthusiasts and power users...
