Vasant Hegde 150bdf5f8d iommu/amd: Fix GT feature enablement again ... Current code configures GCR3 even when device is attached to identity domain. So that we can support SVA with identity domain. This means in attach device path it updates Guest Translation related bits in DTE. Commit de111f6b4f ("iommu/amd: Enable Guest Translation after reading IOMMU feature register") missed to enable Control[GT] bit in resume path. Its causing certain laptop to fail to resume after suspend. This is because we have inconsistency between between control register (GT is disabled) and DTE (where we have enabled guest translation related bits) in resume path. And IOMMU hardware throws ILLEGAL_DEV_TABLE_ENTRY. Fix it by enabling GT bit in resume path.
