This allows users to specify performance events and filters separately for each IOMMU. This has been tested on the new family17h-based server w/ multiple IOMMUs. Git branch containing this patch series is available here: https://github.com/ssuthiku/linux.git perf-iommu-v7 Changes from V6 (https://lkml.org/lkml/2016/12/23/134) * Renamed function parameters from devid to idx (per Joerg). * Removed unnecessary function declarations from amd_iommu_proto.h (per Joerg). Changes from V5 (https://lkml.org/lkml/2016/2/23/370) * Rebased onto v4.9. * Remove the patch which consolidates function delclarations since we have not yet agreed on the appropriate place for the new header file.
