Adds a new driver to support the SMMUv3 PMU and add it into the perf events framework. Each SMMU node may have multiple PMUs associated with it, each of which may support different events. SMMUv3 PMCG devices are named as smmuv3_pmcg_<phys_addr_page> where <phys_addr_page> is the physical page address of the SMMU PMCG wrapped to 4K boundary. For example, the PMCG at 0xff88840000 is named smmuv3_pmcg_ff88840 Filtering by stream id is done by specifying filtering parameters with the event. options are: filter_enable - 0 = no filtering, 1 = filtering enabled filter_span - 0 = exact match, 1 = pattern match filter_stream_id - pattern to filter against Example: perf stat -e smmuv3_pmcg_ff88840/transaction,filter_enable=1, filter_span=1,filter_stream_id=0x42/ -a netperf Applies filter pattern 0x42 to transaction events, which means events matching stream ids 0x42 & 0x43 are counted as only upper StreamID bits are required to match the given filter. Further filtering information is available in the SMMU documentation. SMMU events are not attributable to a CPU, so task mode and sampling are not supported.
