Blender 3.3 is set to be released today and one of the exciting enhancements with this open-source, cross-platform 3D modeling software update is initial support for Intel oneAPI/SYCL GPU acceleration. Intel Arc Graphics discrete GPUs can now enjoy this accelerated Cycles back-end, permitting your driver stack is new enough on Windows or Linux and are using their new dGPUs and not existing integrated graphics. But this is just the start of their oneAPI GPU-accelerated push for Blender...
Since Apple introduced the M1 two years ago as their in-house Apple Silicon for laptops and desktops with a powerful AArch64 processor and custom-designed graphics processor, there has been much speculation about whether the Apple M1 (and now M2) graphics are a clean-sheet Apple design or derived from Imagination PowerVR graphics that Apple had been using with earlier SoCs. There has been some similarities brought up before with the Asahi Linux team working on enabling the Apple M1/M2 under Linux while the latest Mesa driver activity points to more common bits between PowerVR graphics hardware and the Apple AGX graphics...
Formed back in 2019 by Intel, Mozilla, and Red Hat was the Bytecode Alliance to promote running WebAssembly (WASM) everywhere. As part of the Bytecode Alliance initiatives they have been developing Wasmtime as a WebAssembly run-time and later this month they plan to christen version 1.0...

While Intel Arc Graphics is already running on the open-source Linux driver stack, Intel engineers continue improving upon and refining that DG2/Alchemist graphics card support. Overnight some fresh workarounds were merged into Mesa 22.3-devel as the latest Linux driver improvements for Intel's forthcoming discrete graphics cards...
Back in July I called attention to the issue how Linux 5.19 was set to break Alder Lake P graphics support unless moving to new graphics micro-controller "GuC" firmware in tandem. That user-space breakage is frowned upon and following that article the upstream DRM kernel maintainers outlined explicit requirements around firmware not breaking driver support. Intel engineers ended up submitting a quick fix for Linux 5.19 to still support the existing firmware while now a more adequate solution has been devised...
With Fedora 39 next spring it will likely replace DNF, libdnf, and dnf-automatic with the new DNF5 packaging tool and libdnf5 support library. DNF5 should improve the user experience and deliver better performance for dealing with software management on Fedora Linux...
Following the July disclosure of the Retbleed CPU security vulnerability affecting older processors and an AMD change made in August, here is a fresh look at the performance impact of the Retbleed mitigations on Linux, including if opting for the IBPB-based Retbleed mitigation, and the accumulated CPU security mitigation impact for Zen 2 with the flagship Ryzen 9 3950X processor.

Mesa recently landed BPTC software fallback handling that is a requirement for OpenGL 4.2 support but BPTC is not natively supported by all GPU hardware, particularly on the embedded side. That software emulation support for BPTC is similar to what already has existed within Mesa for the ASTC and ETC formats too. A merge request is pending that also adds S3TC software fallback handling, which helps out some of the smaller, embedded GPU drivers too for getting more games running that are dependent on S3 Texture Compression...
While there has been talk and plans for Vulkan API support within Blender, currently there are no active developers working on it and much work remains before it would be ready for end-users...

GravityMark 1.70 has been released as the multi-API graphics benchmark developed by Tellusim Technologies that was started by former Unigine engine CTO and co-founder Alexander Zapryagaev...
Currently when it comes to shipping new/updated device support for firmware updating under Linux with FWUPD/LVFS, it requires making/adjusting a Fwupd plug-in for carrying out the actual firmware copying/updating of the device and then adding in the device VID/PID to a quirks table so Fwupd knows about what to match a given device to for the firmware plug-in to use. Even in new devices where no plug-in changes are required, new device entries are still needed in the quirks table and it makes it challenging when Linux distributions don't quickly move to new FWUPD releases. Moving forward a better solution is being explored...
While it's been years since Canonical dropped Unity as the official desktop environment of Ubuntu, some within the open-source community have still been maintaining it and running an unofficial Ubuntu Unity flavor of the distribution. Now with next month's Ubuntu 22.10 release, Ubuntu Unity will be an official flavor/spin...

The sdl12-compat is a SDL 1.2 compatibility layer implementation atop SDL 2.0. This sdl12-compat project allows for old, out-of-date games and other applications relying on the old SDL 1.2 interface to in turn run via the modern SDL2 library for better compatibility with input devices, Wayland support (assuming no direct X11 hard dependencies), support for PipeWire audio, improved input controls, and various other enhancements only found in SDL 2.0 and not the unmaintained SDL 1.2...
Back in July Intel's Peter Zijlstra proposed "Call Depth Tracking" as a mitigation approach for handling Retbleed and avoiding the "performance horror show" of Indirect Branch Restricted Speculation (IBRS) usage. Out today is the newest version of the Call Depth Tracking code and the performance benchmark results are looking very promising for lessening the pain of the Retbleed CPU mitigation performance impact...
The recently proposed Intel open-source Vulkan driver split where the Gen7/Gen8 graphics support would be shifted off to a separate "new" legacy driver has happened to allow the Intel ANV Vulkan driver to move forward with its Skylake "Gen9" graphics and later focus...
As part of experimenting with using Rust code inside Mesa, longtime Mesa developer Karol Herbst of Red Hat has been developing Rusticl as a new Rust-based OpenCL implementation for Gallium3D and an alternative to the long-standing "Clover" OpenCL state tracker. That Rusticl code with the initial Rust infrastructure for Mesa is expected to be merged in the coming days...

Earlier this year AMD's GPUOpen team announced the Orochi project for dynamic HIP/CUDA run-time handling. Orochi makes it easier for application developers to ship AMD HIP and NVIDIA CUDA support within a single code-base / binary that is then selected at run-time based on the GPU in use...
With the Apple M2 running Asahi Linux you may be wondering whether it's better to use the GCC compiler as is the default on upstream Arch Linux or whether going for LLVM Clang will yield better performance given all the LLVM/Clang usage by AArch64 vendors, including Apple's own Xcode compiler toolchain making use of it. If you are wondering about GCC vs. Clang for building binaries on the Apple M2, here are some benchmarks.
Back in 2013 when AMD was pushing their Heterogeneous System Architecture (HSA) they joined The Document Foundation and wanted to make use of OpenCL acceleration within this open-source office suite. Shortly thereafter they added many OpenCL functions to LibreOffice but now a decade later it seems to be of little use but at least this week thanks to a Collabora engineer there has been some OpenCL code cleaning for this free software office suite...
Inspired by Microsoft's compiler toolchain having a "std:c++latest" option for automatically targeting the latest supported C++ spec, GCC compiler developers have been discussing the possibility of a similar feature with the ability to specify -std=c++current for the current C++ standard or -std=c++future for the future/draft specification...
