But much like aarch64, there is no ilp32 kernel abi for loongarch. >> That said, we don't exclude TYPE_LOONGARCH32_CPU or -cpu la132 from >> CONFIG_USER_ONLY, which is a separate mistake. > > Where should that be done? Probably target/loongarch/cpu.c, by omitting TYPE_LOONGARCH32_CPU and "la132". r~
