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 This sdl12-compat project allows for old, out-of-date games and other applications relying on the old SDL 1.2 interface to in turn run via the modern SDL2 library for better compatibility with input devices,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

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.

This week the Apache Software Foundation is celebrating more than 333 million downloads of their open-source office suite...

Earlier this month Ubuntu 22.04.1 LTS was delayed by one week due to an OEM install bug leading to broken Snaps support. Now with Ubuntu 20.04.5 LTS the Canonical developers are racing down to a last-minute rebuild of images over a NVIDIA proprietary driver issue...

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.

Last week I outlined getting Intel Arc Graphics running on a open-source Linux graphics driver when using Linux 6.0 and later (along with a currently-experimental module option override) and then Mesa 22.2+. Now that I've had more days with the Intel Arc Graphics A380 as the company's budget discrete GPU, here are more of my thoughts on this graphics card that has begun retailing in the US for $139.

Back in early June AMD engineers began posting support for enabling Virtual NMI on Linux for AMD CPUs with KVM and permitting hardware support. VNMI is expected to finally happen on the AMD side with Zen 4 processors and today they posted their latest revision of this work...

Last week I wrote about Mesa's R300 Gallium3D driver seeing new optimizations for R300~R500 class GPUs from the ATI days, thanks to the open-source community. Another merge request is now open that finishes up the latest optimization spree for these old pre-AMD GPUs on Linux...

The ASpeed "AST" DRM driver that is for use with ASpeed BMCs on server platforms for display capabilities is preparing to see DMA-BUF and PRIME sharing support. This is useful so the ASpeed BMC can see the screen contents even if the server is relying on a discrete GPU rather than the baseboard management controller's monitor output...
