While there are the likes of OOMD / systemd-oomd gaining acceptance as a daemon for Linux systems to deal with killing off processes and other behavior under system memory (RAM) pressure, there still is an issue of the time it takes until the memory is reclaimed by those dying processes. Google engineers at the end of June proposed "process_reap" as a new system call to help in that memory recovery...

Besides Azure Cloud Switch as a Linux platform created by Microsoft, the Windows company has also been developing CBL-Mariner (Common Base Linux) as their own internal albeit public and open-source Linux distribution...

For over one year now since Advanced Matrix Extensions (AMX) was first disclosed as a future feature with Xeon "Sapphire Rapids", Intel engineers have been posting AMX patches for enabling the new support for changes needed from the kernel to code compiler stacks. The Linux kernel support for AMX hasn't yet landed but has now been revised its seventh time for public review...

Going back to 2017 was work on firmware-based power management for Intel graphics with its GuC implementation. That work didn't advance with the time but now with Intel renewing their work around GuC and with future hardware may mandate this binary-only firmware, they are again revisiting the GuC power management...

Linux 5.14 has re-landed support for improvements to lower the latency of its USB audio driver...

Back in April was the release of Vulkan Video extensions for GPU-accelerated video encode/decode using this cross-platform API. NVIDIA was quick to publish a beta driver with Vulkan Video support while adoption beyond that by drivers or multimedia software has been rather limited so far. Fortunately, the popular GStreamer multimedia framework for Linux users is working in the direction of supporting Vulkan Video...

Shortly after OpenCL 3.0 was finalized last year it was enabled for Intel's open-source Compute Runtime stack (and even earlier with their Tiger Lake enablement). But since last year that OpenCL 3.0 support was marked as "beta" while last week was quietly promoted to being "production" grade...

XWayland 21.1.2 is out today and while it may seem like "just a point release", it's quite an exciting one at that since it does bring NVIDIA hardware acceleration for XWayland when paired with their new NVIDIA 470 series driver...

AMD has published its first code drop of the quarter for their open-source "AMDVLK" Vulkan driver that is derived from their official driver sources but making use of the AMDGPU LLVM compiler back-end rather than their proprietary shader compiler...

Fixes to the Plasma Wayland session continue to be quite steady work in the KDE camp even with the support becoming quite mature and good enough for day-to-day use...

The Linux 5.14 char/misc updates landed this week in the kernel. The "char/misc" area continues to serve as a growing catch-all portion of the code-base not jiving well elsewhere in other subsystems...

LLVM 12.0.1 is available today as the only planned point release to this spring's release of LLVM 12...

Last summer I wrote about Intel prototyping their Mesa drivers to use the IGC compiler, which followed Intel transitioning their Windows driver to use this compiler that was originally written for their open-source Linux compute stack. While they were making good progress last year on having their Mesa drivers use the IGC compiler, the project has been pushed back...

The Linux 5.14 input subsystem updates have landed with new hardware support and other changes...

Earlier this year was the proposed NVIDIA code from NVIDIA for allowing Mesa's GBM to support alternative back-ends. This support is notable given that most Wayland compositors are catering to using Mesa's Generic Buffer Manager (GBM) rather than EGLStreams or other options for buffer management. That support code has now been merged into Mesa 21.2...

Adding to the lengthy list of features for Intel's next-gen Xeon "Sapphire Rapids" processors next year is an admittedly experimental feature called RAR, or Remote Action Requests...
