Introduced to the mainline kernel two years ago with Linux 5.12 was the IDMAPPED mounts functionality that is useful from systemd-homed to containers and other use-cases. Since then more Linux file-systems and software has added support for IDMAPPED mounts and it's being furthered along now with Linux 6.3...

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. For those more interested in creator workloads and GPU OpenCL and CUDA compute performance for these high-end consumer Ada Lovelace graphics cards, this article is for you with an initial look at the compute performance across a wide range of workloads from Blender OptiX and CUDA rendering to common OpenCL GPU benchmarks.

Sent out today for the Linux 6.3 kernel merge window are the updates to the printk code. Notable this time around are preparations to printk in working toward threaded/atomic consoles support. That threaded/atomic consoles support is all the more important as it's the last piece of the puzzle before the remainder of the real-time (PREEMPT_RT) patches can be upstreamed into the Linux kernel...

Merged back in December was the initial GCC Rust front-end "gccrs" for the GCC 13 compiler that will be released as stable within the next month or two. Squeezing today into the GCC 13 code-base is an additional 103 patches for this Rust front-end...
