While support for the loongArch Chinese CPU architecture was merged in Linux 5.19, it wasn't actually enough to yield a booting system due to some driver code not yet being finished and ready for merging in time. LoongArch was allowed to merge that preliminary code in v5.19 so the Glibc support could land and now for Linux 6.0 more of the CPU port is ready to hit the kernel...

When it comes to the Apple M1 and M2 support on Linux, one of the biggest obstacles to suitable daily use for end-users is the current lack of GPU acceleration. Reverse engineering has been happening for the Apple Silicon graphics processor, early experiments being carried out under macOS and Asahi's m1n1 environment, and the next step will be to start writing a Direct Rendering Manager (DRM) kernel driver. To some surprise, the feasibility of writing this DRM kernel GPU driver in the Rust programming language is being explored...
