Subject: [PATCH 0/6] perf/amd/iommu: Enable multi-IOMMU support

This patch series modifies the existing perf_event_amd_iommu driver
to support systems with multiple IOMMUs. It introduces new AMD IOMMU APIs,
which will are used by the AMD IOMMU Perf driver to access performance
counters in multiple IOMMUs.

In addition, this series should also fix current AMD IOMMU PMU driver
initialization issue in some existing CZ platform.

Suravee Suthikulpanit (6):
  perf/amd/iommu: Consolidate and move perf_event_amd_iommu header
  perf/amd/iommu: Modify functions to query max banks and counters
  iommu/amd: Introduce amd_iommu_get_num_iommus()
  perf/amd/iommu: Introduce data structure for tracking prev count.
  perf/amd/iommu: Introduce get_iommu_bnk_cnt_evt_idx
  perf/amd/iommu: Enable support for multiple IOMMUs
