The ARMv8.3-SPE adds an Alignment Flag in the Events packet and filtering on this event using PMSEVFR_EL1, together with support for the profiling of Scalable Vector Extension operations.
Patch 1: Update the kernel driver, mainly for PMSEVFR_EL1.
Patch 2: Update the decode process of Events packet and Operation Type packet in perf tool.
Patch 3-4: Synthesize unaligned address access events and partial/empty predicated SVE events, also add two itrace options for filtering.
