The UBports folks have released Ubuntu Touch OTA-18 as their latest over-the-air update for this mobile Linux platform. Notable with this release is what isn't there - the Ubuntu 20.04 base.

It's well known that the Linux desktop can be quite unbearable when under heavy memory pressure as has been showcased over the years and more attention these days turning to the likes of OOMD/systemd-oomd and other alternatives to better deal with Linux low/out-of-memory scenarios especially with today's desktop software and web browsers consuming increasing amounts of memory. Another effort coming to fruition for helping this scenario is the "le9" Linux kernel patches...

Mozilla has officially released Firefox 90.0 as the latest monthly update to their cross-platform web browser...

Being worked on for quite a while now by longtime kernel developer Matthew Wilcox of Oracle is memory folios to improve Linux's memory management and allow for greater efficiency. Benchmarks with memory folios have shown for example kernel builds can be up to 7% faster. It's looking like there is a desire to see at least some of this folios code land for Linux 5.15...

For several years already the AMDGPU kernel driver has supported virtual display functionality for cases like headless GPUs, pre-silicon hardware bring-up, GPUs/accelerators that lack physical display outputs, and other similar use-cases. That virtual display code is now being overhauled by re-using the existing VKMS DRM driver...

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...

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.
