Subject: [PATCH v2 3/3] perf/smmuv3: Synthesize IIDR from CoreSight ID registers
Date: Wed, 17 Nov 2021 14:48:45 +0000 [thread overview]
Message-ID: <20211117144844.241072-4-jean-philippe@linaro.org> (raw)

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.
