For modern Intel platforms supporting Coreboot whether it be for Chromebooks or on server platforms, they are still beholden to the Intel Firmware Support Package (FSP) binary blobs. But Google and Intel engineers have been working to enable more flexibility around the FSP binaries by being able to optionally reduce the amount of proprietary firmware executed on the CPU, optionally weeding out some of the optional FSP components, and optimizing the status quo to achieve greater boot speeds...

With X-Plane 12.04b3, that goal is finally realized...

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.
