Usage of current R1 ISA is inconsistent with the MIPS32 subtarget, little used and has limited utility for testing. Many distros target a minimum R2 ISA. Debian MIPS 32-bit/64-bit ports all use MIPS R2 ISA since Stretch, for example. Fedora's MIPS arch also targets the R2 ISA for 32-bit/64-bit. Widely used MIPS64 platforms like Octeon are based on the MIPS R2 ISA or later, and benefit from having a compatible test platform in OpenWRT. While Linux does support MIPS64 R1 targets, its usefulness for development and testing is limited. As an example, the modern Linux eBPF JIT requires a MIPS R2 ISA or later.
