About

The RVA23 profiles are intended to be used for 64-bit application processors that will run rich OS stacks from standard binary OS distributions and with a substantial number of third-party binary user applications that will be supported over a considerable length of time in the field. The approach is to provide a large guaranteed set of features that can safely be exploited by third-party developers to ship binaries that will provide a better experience across a large number of alternative implementations over time. It is explicitly a non-goal of RVA23 to allow more hardware implementation flexibility by supporting only a minimal set of features.

Only user-mode (RVA23U64) and supervisor-mode (RVA23S64) profiles are specified in this family.
