PAv3 PMU: Compared with the PAv2 PMU, the PAv3 PMU has different event. The version of PMU version register is used to distinguish the v2 and v3. H60PA PMU: The H60PA PMU and PA are two different devices. The H60PA PMU supports higher bandwidth, and the PA PMU delay is relatively low. Different HIDs are used to distinguish the delay. UC PMU: Each cluster is integrated with a unified cache (UC) PMU, which provides consistency between NUMA and UMA domains. It sits between L2 and the memory system. Change since v3: - Modify the UC PMU patch commit message according to Jonathan's comment. Link: https://lore.kernel.org/linux-arm-kernel/20230608113719.27433-1-hejunhao3@huawei.com/ Change since v2: - Modify the driver description according to Jonathan's comment.
