Chinese vendor Loongson continues working on their Linux kernel patches enabling the LoongArch processor ISA as their fork from MIPS. While early on when copying existing MIPS open-source code they were quick to call their new ISA "not MIPS", in these later patch series they continue to refer to their ISA as "a bit like MIPS or RISC-V."..

One of many exciting additions with the forthcoming Linux 5.15 kernel is DAMON landed as a data access monitoring framework.
