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 v1: - Improve according to Yicong's suggestion - Fixes build warning of "-Wmissing-prototypes" Link: https://lore.kernel.org/lkml/20230523131825.6102-1-hejunhao3@huawei.com/ Junhao He (3): drivers/perf: hisi: Add support for HiSilicon H60PA and PAv3 PMU driver drivers/perf: hisi: Add support for HiSilicon UC PMU driver docs: perf: Add new description for HiSilicon UC PMU Documentation/admin-guide/perf/hisi-pmu.rst | 8 + drivers/perf/hisilicon/Makefile | 2 +- drivers/perf/hisilicon/hisi_uncore_pa_pmu.c | 142 ++++- drivers/perf/hisilicon/hisi_uncore_pmu.c | 4 +- drivers/perf/hisilicon/hisi_uncore_pmu.h | 15 + drivers/perf/hisilicon/hisi_uncore_uc_pmu.c | 577 ++++++++++++++++++++ 6 files changed, 731 insertions(+), 17 deletions(-) create mode 100644 drivers/perf/hisilicon/hisi_uncore_uc_pmu.c
