Changes since RFC: - Refact arm-cmn PMU identifier. - Not add arm-cmn PMU aliasing currently because it's Eventcode is difficult to define. - Rename ali_drw PMU identifier and Unit name. - Divide ali_drw PMU metric and aliasing into two patches. Add an identifier sysfs file for the yitian710 SoC DDR and arm CMN to allow userspace to identify the specific implementation of the device, so that the perf tool can match the corresponding uncore events and metrics through the identifier. Then added several general CMN metrics and yitian710 soc DDR metrics and events alias. $perf list: ... ali_drw: chi_rxdat [A packet at CHI RXDAT interface (write data).
