As Peter says, someone has to step up andf do the work for ARM32 SMP. That said, it probably doesn't make sense to work on that until ARM64 SMP is stable. A port of the ARM64 pmap to ARM32 would be easier than trying to implement SMP on the existing ARM32 pmap. - todd

Just to understand, ARM64 has SMP and ARM32 does not? &, OpenBSD design fine with ARM's weak mem coherency?
Hi misc, I just wanted to understand what's going on with SMP on ARM - Did I get it right, that ARM64 has SMP (as of the patches this week), but ARM32 does not have SMP and will not get it too? What was the reason for not implementing SMP on ARM32? (I only need SMP on ARM64 so just wanted to ask as to understand what's going on.) Also, is there any confrontation between OpenBSD's design and ARM's weak memory coherency model? (In contrast with AMD64/I386/SPARC64 which all have a strong model.) Thanks! Tinker
