Subject: [PATCH 0/6] perf/amd/iommu: Enable multi-IOMMU support
Date: Tue, 22 Dec 2015 13:19:11 -0600 [thread overview]
Message-ID: <1450811957-1511-1-git-send-email-Suravee.Suthikulpanit@amd.com> (raw)
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
