It is a PCIe Root Complex integrated End Point(RCiEP) device added on Hip09. Each PCIe Core has a PMU RCiEP to monitor multi root ports and all Endpoints downstream these root ports. HiSilicon PCIe PMU is supported to collect performance data of PCIe bus, such as: bandwidth, latency etc. This patchset is based on 5.13-rc1.
