Mesa 24.1 Git has landed the initial infrastructure for allowing drivers to choose to using Zink instead for OpenGL via this OpenGL-on-Vulkan implementation. The motivating factor for this latest Mesa work is for using Zink atop the NVK Vulkan driver for newer NVIDIA GPUs...

When it comes to today's complex RGB lighting for PC peripherals and the like it's mostly been left up to user-space. With most RGB devices interfacing via USB, it's been up to Linux user-space projects like OpenRGB, OpenRazer, etc, to implement their RGB lighting controls as needed. But as RGB lighting use continues to grow in the PC space for better or worse, there's an increasing need for a kernel API to handle complex RGB devices. Such an API is currently being devised...

As many enthusiasts wait to hear from AMD more broadly supporting ROCm in an official capacity across consumer Radeon GPUs and/or hearing about better supporting more Linux distributions outside of the major enterprise Linux distributions, today AMD announced a new medium for their communications with the community: the "New AMD ROCm Software Blog Platform" will be rolling out...

Earlier this month I posted some initial CPU benchmarks of the NVIDIA GH200 Grace Hopper up against AMD EPYC Zen 4 and Intel Xeon Emerald Rapids processors. That was a very interesting battle and showed the interesting capabilities of the 72 Arm Neoverse-V2 cores. With this GPTshop.ai GH200 system actually being in workstation form, I also ran some additional benchmarks looking at the CPU capabilities of the GH200 compared to AMD Ryzen Threadripper 7000 series workstations.

For years Wine developers have been after a better synchronization API for the Linux kernel to better match the semantics of Microsoft Windows. Posted back in January was a request for comments on an "NTSYNC" Linux kernel driver to implement Windows NT synchronization primitives for the Linux kernel. At the start of the month a post-RFC version was posted of this open-source driver and today the latest iteration of that work has been published to the kernel mailing list...

For over two years Red Hat's engineers working on the Anaconda installer have been working on a modern web-based installer UI that integrates with Cockpit and is a modern alternative to their GTK-based installer interface for deploying Fedora Linux and eventually RHEL too. The hope was to offer this web UI installer option for Fedora Workstation 40 but that's now been delayed to Fedora 41...

Back in January 2023 was an attempt to disable kernel drivers for Microsoft's RNDIS protocol. The Remote Network Driver Interface Specification (RNDIS) is home to security concerns for this protocol built atop USB for virtual Ethernet functionality. Later in the year the effort to disable RNDIS on Linux was tried again without going mainline. In recent days it looks like there will be a fresh attempt at getting the RNDIS driver support disabled...

Longtime Linux kernel developer Thomas Gleixner with Intel-owned Linutronix has been spending much time over the past several months reworking the Linux kernel's x86 CPU topology evaluation code. This is to clean-up a mess of aging kernel code as well as some areas of the code being incorrect in today's era of hybrid Intel Core processors with a mix of P / E cores with the E cores lacking SMT/HT and thus throwing off prior kernel assumptions. With the code now queued up in a TIP branch today, it looks like that CPU topology rework could be good to go with Linux 6.9...

The FreeBSD project today issued their Q4'2023 status report that highlights all of their interesting work accomplished last quarter on this open-source platform. Among the interesting achievements were the FreeBSD Foundation sponsoring AMD64 SIMD improvements for FreeBSD 15 that will also be back-ported to FreeBSD 14.1...

Merged to the LLVM compiler stack two years ago was the BOLT tool for optimizing the layout of generated binaries for offering even greater performance than the likes of Profile Guided Optimizations (PGO) alone. BOLT had been in development for years by Facebook/Meta engineers and has continued to be improved upon for enhancing the code layout of binaries to yield enhanced performance. Recently there's been renewed work on using BOLT to optimize Linux kernel images...

Ahead of the SUSE/openSUSE Adaptable Linux Platform (ALP) their engineers have been working on a new web-based OS installer. Originally known as the "D-Installer" and now going by the "Agama" name, this new installer architecture has plans for many architectural improvements this calendar year...

Intel engineers working on their open-source Mesa OpenGL/Vulkan driver code currently replay captured error state / GPU hangs using a simulator, but a new patch proposal allows for replaying GPU hangs on the actual hardware. In turn this will hopefully help Intel driver developers better address some real-world issues...
