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...
