    Subject[PATCH v3 0/2] drivers/perf: hisi: Add support for PCIe PMU
    Date
    This patchset adds support for HiSilicon PCIe Performance Monitoring
    Unit(PMU). 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 5.12-rc6.

    Changes since v2:
    - Address the comments from John.
    - Link: https://lore.kernel.org/linux-arm-kernel/1617959157-22956-1-git-send-email-liuqi115@huawei.com/

    Changes since v1:
    - Drop the internal Reviewed-by tag.
    - Fix some build warnings when W=1.
