Armv8.3 extends the SPE by adding: - Alignment field in the Events packet, and filtering on this event using PMSEVFR_EL1. - Support for the Scalable Vector Extension (SVE). The main additions for SVE are: - Recording the vector length for SVE operations in the Operation Type packet. It is not possible to filter on vector length. - Incomplete predicate and empty predicate fields in the Events packet, and filtering on these events using PMSEVFR_EL1. Update the check of pmsevfr for empty/partial predicated SVE and alignment event in SPE driver.
