While the Vulkan high performance graphics and compute API is backed by many vendors, Microsoft and Apple are two notable organizations that haven't backed this Khronos Group standard. For Microsoft's part, they obviously prefer their in-house Direct3D. However, Microsoft is making preparations for submitting their first Vulkan extension.

AMD engineers have been working out many quirks and oddities in system suspend/resume handling to make it more reliable on their hardware particularly around Ryzen laptops. In addition to suspend/resume reliability improvements and suspend-to-idle (s2idle) enhancements, one of their engineers also discovered an easy one-liner as a small step to speeding up system resume time.

Ivan Orlov this past week posted the patches for VALSA, the Virtual ALSA sound driver that aims to help Linux kernel developers in testing and fuzzing of the sound subsystem.

Hans-Kristian Arntzen of Valve's Linux team has just released VKD3D-Proton 2.9 as the latest major update to this Direct3D 12 on Vulkan API implementation that is used by Steam Play (Proton) for running modern Windows games on Linux.

CodeWeavers, the company known for its CrossOver software for running Windows games/apps on Linux / macOS / Chrome OS and in turn being the main corporate backer to the Wine project, is now transitioned to being an employee ownership trust. This comes with Jeremy White deciding to leave the company after 27 years.

There's a new open-source Vulkan driver in development by an independent developer that is working on providing support for aging Radeon HD 6000 series "Northern Islands" graphics processors.

There's been a Fedora 39 proposal under evaluation for boosting the kernel's vm.max_map_count to help with some Windows games on Steam Play. Though concerns were raised that bumping this kernel tunable too high may not be wise. As such, further testing is to happen for tuning Fedora's stock vm.max_map_count value.

Nearly forty years after the MIDI digital music protocol was first introduced, in 2020 the MIDI 2.0 protocol was announced as a major overhaul for this widely used standard by musical devices. A big patch series sent out today prepares the Linux kernel sound drivers for MIDI 2.0.

Intel's open-source Mesa Vulkan Video driver "ANV" has added support for H.265 (HEVC) video decoding.

Bug bounty programs setup by large corporations to reward and recognize security researchers for properly reporting new bugs and security vulnerabilities is a great concept, but in practice isn't always handled well. Security researcher Adam Zabrocki recently shared the troubles he encountered in the bug bounty handling at Google for Chrome OS and in turn for Intel with it having been an i915 Linux kernel graphics driver vulnerability.

The sdl12-compat project that implements the SDL 1.2 API/ABI atop SDL 2.x interfaces for better game compatibility on modern Linux systems is out today with a new pre-release.

NVIDIA today announced the GeForce RTX 4060 series consisting of the $399 RTX 4060 Ti 8GB while in July an RTX 4060 Ti 16GB version will come along with a $299 RTX 4060.

Following last month's Red Hat hosted HDR hackfest that brought together many Linux desktop stakeholders from GPU driver developers to desktop environment developers, KDE developer Xaver Hugl has shared an update on the progress being made for high dynamic range (HDR) display support from the KWin side.

With development of the MIPS architecture having officially ended two years ago in favor of focusing on RISC-V for future CPU designs and the overall decline of that CPU architecture, it's been years since the GNU Compiler Collection (GCC) has seen its MIPS code well maintained. However, now a capable developer has stepped up willing to serve as the GCC maintainer for MIPS.

Earlier this month Red Hat released RHEL 9.2 and at the same time they also released RHEL 8.8 for those continuing to rely on the stable RHEL8 series. AlmaLinux managed to provide a same-day release of AlmaLinux 9.2 while now one week later they have also shipped AlmaLinux 8.8.

While for an Ubuntu desktop user that is used to running Snap versions of Firefox and other desktop application sandboxing it may seem strange for Canonical to be comparing Snaps to Docker containers, the emphasis of their comparison is on the IoT/edge computing side where they are trying to better position Snaps as a superior alternative to using Docker containers.

The OpenBMC Linux Foundation collaborative project providing an open-source operating system / firmware stack for server baseboard management controllers (BMCs) is out with version 2.14.
