Revision 1da8347d8505c137fb07ff06bbcd3f2bf37409bc authored by Megha Dey on 14 March 2020, 03:39:59 UTC, committed by Joerg Roedel on 14 March 2020, 19:02:43 UTC
Currently, the intel iommu debugfs directory(/sys/kernel/debug/iommu/intel)
gets populated only when DMA remapping is enabled (dmar_disabled = 0)
irrespective of whether interrupt remapping is enabled or not.
Instead, populate the intel iommu debugfs directory if any IOMMUs are
detected.
