With the AMD Radeon "HIP" acceleration in Blender 3.2 with the Cycles back-end, an unfortunate early limitation is that this is limited to just AMD RDNA2 (Radeon RX 6000 series) graphics processors while prior generation RDNA1 GPUs have issues with some textures like those used in the benchmarks. This week though AMD did post a new patch for Blender enabling HIP support on Windows and Linux for Vega/GFX9 graphics...

Stemming from my recent AWS Graviton3 benchmarks and looking at Graviton3 against Intel Xeon and AMD EPYC, a number of Phoronix readers expressed interest in seeing some compiler tuning benchmarks for the Graviton3 around its Arm Neoverse-V1 cores with SVE support. Here are some benchmarks for those interested in the compiler tuning impact for this new high performance Arm cloud processor.

Found with Intel mobile SoCs since Ice Lake is their Gaussian and Neural Accelerator "GNA" that has been supported by an out-of-tree Linux driver while over the past year Intel engineers have been working to upstream an Intel GNA Linux driver into the mainline kernel. They have most recently been adapting this GNA driver to become a Direct Rendering Manager (DRM) driver alongside their Intel i915 kernel graphics driver and other conventional graphics drivers...

Due to the early state of Imagination's PowerVR Rogue open-source Vulkan driver within Mesa a "hard coding" infrastructure has been added for helping to load hard-coded graphics/compute shaders into this driver until its compiler is far enough along to be useful and mark this infrastructure as unnecessary/redundant...

Statistics published by Fedora for the Extra Packages for Enterprise Linux (EPEL) usage point to a recent surge in Rocky Linux usage -- at least for those with EPEL enabled -- and at least recently appears to surpass the usage for the likes of CentOS Stream, AlmaLinux, and even the RHEL usage with EPEL enabled...

When an EXT4 file-system is running low on free space (or when toggled via the "nodelalloc" mount option), EXT4's delayed allocation mode can be disabled. This can result in a significant performance hit but now a patch is pending for what should land in Linux 5.20 with recovering that performance when delayed allocation is disabled...

Yesterday I posted benchmarks of six Linux distributions on the HP Dev One, the exciting new Linux laptop launched by HP in collaboration with System76 that is using their Pop!_OS distribution. From those benchmarks one of the bizarre findings was that the Zstd compression performance on Arch Linux simply sucked, but some interested developers dove in and found the rather bizarre culprit why their Zstd performance is so poor in relation to other Linux distributions on the same version...
