POCL as the "Portable Computing Language" that gets OpenCL running on CPUs as well as via LLVM allowing for targeting NVIDIA GPUs, AMD HSA environments, and other cases, is now preparing to roll-out OpenCL 3.0 support.

The open-source POCL project so far has officially supported OpenCL 1.2 with some OpenCL 2.0 functionality in place for this CPU-focused support and other multi-device/heterogeneous compute built atop LLVM. With this morning's POCL 3.0 release candidate,

Multi-Gen LRU ( MGLRU ) remains a very promising effort for enhancing Linux system performance and particularly about providing a superior experience when the Linux kernel is dealing with system memory pressure. MGLRU v11 was posted this week while we await to see if it will be mainlined come the v5.19 merge window.

The MGLRU effort led by Google's Yu Zhao is about improving the Linux kernel's page reclamation code after they found it to be too expensive and making poor eviction choices. MGLRU has

PAPPL as the free software project started by CUPS founder Michael Sweet after departing Apple more than two years ago, this C-based framework/library for creating CUPS Printer Applications is out with a major feature release.

PAPPL aims to be a replacement for printer drivers and is designed around the needs of the LPrint and Gutenprint software. PAPPL is Apache 2.0 licensed and engineered with modern printers in mind. PAPPL 1.2 was released on Sunday as the project's latest stable feature update, succeeding the earlier PAPPL

Another Intel (open-source) software update coinciding with the company's Vision 2022 conference is a new oneAPI Level Zero Loader release.

The oneAPI Level Zero Loader provides the actual loader for loading client/driver support, validation layer support, and a copy of the reference L0 specification API header files. The oneAPI Level Zero Loader works with both Windows and Linux systems.

With the oneAPI Level Zero Loader v1.8.0 there is now support for new features found as part of the

The Alliance for Open Media already has a public repository serving as the reference software implementation for "AVM" as the AOM Video Model as the next-generation codec from this alliance responsible for the excellent AV1.

A Phoronix reader pointed out to me that AOMedia now has a public repository for AVM. I haven't seen this mentioned elsewhere yet but it's the real deal and is the work-in-progress software implementation for what will eventually be the planned successor to AV1.

The AVM Git repository

Rusticl as what started out as a Rust language experiment for Mesa and has now matured into a working OpenCL 3.0 implementation for Mesa drivers is still making progress and on a path towards eventually being mainlined.

In addition to the OpenCL 3.0 conformance test suite (CTS) successfully running on the Mesa Rusticl code along with various test applications (including Rusticl having OpenCL image support), the latest milestone to mark off the list is it successfully running with Darktable's OpenCL support.
