[PATCH 2/4] perf: arm-spe: Add support for ARMv8.3-SPE

2020-07-24 Thread Wei Li
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
