    Subject[PATCH 0/2 V3] perf/x86/amd: IOMMU Performance Counter Support
    Date
    From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>

    These patches implement the AMD IOMMU Performance Counter functionality
    via custom perf PMU and implement static counting for various IOMMU
    translations.

    1) Extend the AMD IOMMU initialization to include performance
    counter enablement.

    2) The perf AMD IOMMU PMU to manage performance counters, which
    interface with the AMD IOMMU core driver.
