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...

After a series of alpha and beta releases over the past several months, out this past week is the first release candidate of the upcoming PHP 8.2...

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...

There is a lot of last minute feature work and improvements heading into Plasma 5.26 ahead of its upcoming beta and feature freeze...

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.

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 This sdl12-compat project allows for old, out-of-date games and other applications relying on the old SDL 1.2 interface to in turn run via the modern SDL2 library for better compatibility with input devices,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...

Intel's open-source "ANV" Vulkan driver for Linux systems has added support for the newly-ratified Vulkan mesh shader extension...

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...

Vulkan 1.3.226 is out this morning and to much excitement adds the VK_EXT_mesh_shader extension as cross-vendor functionality for mesh shaders!..

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...

One of the interesting capabilities with Thunderbolt and now USB4 that is seemingly not too widely used is for networking between systems. The Linux kernel for the past half-decade already has offered a Thunderbolt networking driver for networking between hosts with Thunderbolt cables. The latest improvement on this front is now supporting USB4's end-to-end flow control mode...

Fwupd 1.8.4 not only adds support for some new hardware and fixes but notably begins adding the infrastructure to allow facilitating BIOS changes to the system from within Linux...

With Intel's Meteor Lake moving to a tiled/chiplet approach, we have already seen some interesting changes on the Linux driver side and confirmation of the introduction of a "Versatile Processing Unit" coming with Meteor Lake (MTL) for inference acceleration. Another interesting confirmation from new Linux driver patches is their media encode/decode moving to a "standalone media" Graphics Technology (GT) block...

Mainlined to the Linux kernel less than one year ago was the "asus_wmi_ec_sensors" for supporting temperature / fan speed / CPU current sensor reading on a variety of newer ASUS motherboards. That driver is now being removed as a superior driver is taking over the ASUS motherboard sensor reading duties...
