Subject: [PATCH v1 0/7] perf arm-spe: Refactor data source encoding
As more Arm CPU variants (not only Neoverse CPUs) support data source
encoding, they share the same format for the data source packet.
To extend supporting these CPU variants for Arm SPE data source, this
series refactors the code. It converts the Neoverse specific naming to
the common naming, and then based on the MIDR stored in the metadata to
decide if the CPU follows up the common encoding format.
At the last, it extends CPU list for Neoverse-V2 and Cortex CPUs.
This patch series is dependent on:
