The code is based on ARM Coresight PMU architecture and ACPI ARM Performance Monitoring Unit table (APMT) specification below: * ARM Coresight PMU: https://developer.arm.com/documentation/ihi0091/latest * APMT: https://developer.arm.com/documentation/den0117/latest Notes: * There is a concern on the naming of the PMU device. Currently the driver is probing "arm-coresight-pmu" device, however the APMT spec supports different kinds of CoreSight PMU based implementation. So it is open for discussion if the name can stay or a "generic" name is required. Please see the following thread: http://lists.infradead.org/pipermail/linux-arm-kernel/2022-May/740485.html Changes from v1: * Remove CPU arch dependency. * Remove 32-bit read/write helper function and just use read/writel. * Add .is_visible into event attribute to filter out cycle counter event. * Update pmiidr matching. * Remove read-modify-write on PMCR since the driver only writes to PMCR.E. * Assign default cycle event outside the 32-bit PMEVTYPER range. * Rework the active event and used counter tracking.
