The ops->default_domain flow used a 0 req_type to select the default domain and this was enforced by iommu_group_alloc_default_domain(). When !CONFIG_IOMMU_DMA started forcing the old ARM32 drivers into IDENTITY it also overroad the 0 req_type of the ops->default_domain drivers to IDENTITY which ends up causing failures during device probe. Make iommu_group_alloc_default_domain() accept a req_type that matches the ops->default_domain and have iommu_group_alloc_default_domain() generate a req_type that matches the default_domain. This way the req_type always describes what kind of domain should be attached and ops->default_domain overrides all other mechanisms to choose the default domain. Fixes: |
