In fact, only uncore PMUs aliasing is supported for when the uncore PMUs are fixed for a CPU, which may not always be the case for certain architectures. This series adds support for PMU event aliasing and metrics for system and other uncore PMUs which are not tied to a specific CPU. For this, we introduce system event tables in generated pmu-events.c, which contain a per-SoC table of events of all its system PMUs. Each per-PMU event is matched by a "COMPAT" property. When creating aliased and metrics PMUs, we treat core/uncore and system PMUs differently: - For CPU PMUs, we always match for the event mapfile based on the CPUID. This has not changed. - For an system PMUs, we iterate through all the events in all the system PMU tables. Matches are based on the "COMPAT" property matching the PMU sysfs identifier contents, in /sys/bus/event_source/devices//identifier Uncore PMUs, may be matched via CPUID or same as system PMU, depending on whether the uncore PMU is tied to a specific CPUID. Initial reference support is also added for ARM SMMUv3 PMCG (Performance Monitor Event Group) PMU for HiSilicon hip09 platform with only a single event so far - see driver in drivers/perf/arm_smmuv3_pmu.c reference.
