From: Robin Murphy<robin.murphy@arm.com> The SMMU_PMCG_IIDR register was not present in older revisions of the Arm SMMUv3 spec. On Arm Ltd. implementations, the IIDR value consists of fields from several PIDR registers, allowing us to present a standardized identifier to userspace.
So is there some userspace part to go with this now? Thanks, John _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
