I agree the default should always be to have a kernel that works on every machine that has been produced, but this also depends on which models specifically lack the unaligned access. If it's just about pre-production silicon that is now all but scrapped, things are different from a situation where users may actually use them for normal workloads. Is there an overview of the available loongarch CPU cores that have been produced so far, and which ones support unaligned access?
So far, produced CPUs based LoongArch include 3A5000, 3B5000, 3C5000L, 3C5000, 2K2000, 2K1000LA and 2K0500, where 2K1000LA and 2K0500 are unaligned-access-unsupported, and others are unaligned-access-supported.
