Subject: [PATCH 0/2 V3] perf/x86/amd: IOMMU Performance Counter Support

From: Suravee Suthikulpanit <suravee.suthikulpanit@....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.
