Microsoft's in-house Linux distribution CBL-Mariner has been public now for about two years. CBL-Mariner has been in use for Microsoft's use-cases from their Azure cloud to Windows Subsystem for Linux (WSL) while their newest release continues a recent trend of pointing towards a high performance computing (HPC) workloads focus too...

Merged on Thursday to Mesa 23.1 was implementing VK_EXT_pipeline_library_group_handles using hashed stages with support for caching and replay.

Intel's open-source Compute-Runtime stack for OpenCL and oneAPI Level Zero support along with the Intel Graphics Compiler (IGC) had been on a rhythm of typically seeing new tagged releases every week or two... Quite nice and living up to the open-source development philosophy of "release early, release often." That persisted for a long time until Q4'22 when the releases became less frequent. In early December though the release train stopped and not until this morning has there been a new release of the Compute-Runtime and IGC...

Intel Trust Domain Extensions (TDX) is one of the new features with 4th Gen Xeon Scalable "Sapphire Rapids" processors but is limited this generation to deployment by a few select cloud partners.

A patch series started by Intel to improve the Linux kernel's fair scheduler code, which has also seen testing/feedback from AMD engineers and other stakeholders, continues to be improved upon. The focus of this patch series is on avoiding too many cross-CPU wake-ups when they are unnecessary. In doing so, these patches help enhance the Linux performance particularly on high core count systems...

While Ubuntu Linux hasn't provided Flatpak support out-of-the-box due to their preference of using their own Snap app packaging/distribution format, Ubuntu flavors/spins have to this point been able to pre-install Flatpak support if they desired. However, for the 23.04 "Lunar Lobster" cycle and moving forward, Ubuntu flavors will no longer be permitted to install Flatpak packages by default...

A week after seeing X.Org display driver updates for old Trident and S3 Graphics hardware, a new release of xf86-video-ark is now available that provides the open-source UMS display driver support for old ARK Logic hardware.

The Linux 6.3 merge window has been off to a good start with Linus Torvalds receiving plenty of pull requests in advance, the other early pulls all coming in quite orderly, and no colorful commentary on any of the material set for Linux 6.3 even with the likes of Microsoft Pluton (TPM2 CRB). But today Torvalds' did feel the need to share some wisdom around Git merge log message advice...

Last week I published a number of Linux gaming benchmarks for the GeForce RTX 4080 and RTX 4090 high-end graphics cards now that they finally arrived for my Linux testing on Phoronix.
