Yes, in some cases. On platforms without the security extensions, HVC must be used, as SMC is undefined and cannot be trapped at any higher exception level. Given this, I would expect software at EL2/Hyp to only handle HVC from lower exception levels, as this consistently works even when SMC is undefined. Does that help at all?
