One of the rather elusive items on the Linux desktop is High Dynamic Range (HDR) display support... There's been code in the works for years but across desktops and drivers, it's still a long-term effort getting HDR support on the Linux desktop. Even going back to 2016, with NVIDIA's cross-platform driver code the Linux desktop remained the bottleneck. There is at least some ongoing work to address this long-term issue with AMD this week presenting on the topic.

Merged last month into Mesa 22.3 was Rusticl as a Rust-written OpenCL implementation for Gallium3D that is beginning to work with the open-source Radeon Linux driver, the Intel "Iris" Gallium3D driver, and others.

The real-time "RT" mainlining effort for the Linux kernel remains ongoing. While the finish line is coming near, PREEMPT_RT support for mainline still isn't over the last hurdle -- seemingly the main blocker it's still held up by are the printk changes with threaded console printing. But for the Linux 6.1 merge window there is at least more kernel code clean-ups.

A kernel hardening security improvement on the way for Linux 6.1 is the ability to provide warning of possible memcpy() based overflows. Right now this is only a warning but it's work towards being able to address "trivially detectable" buffer overflow conditions within the kernel and in the future may be able to block such overflows from happening.
