Moritz Fischer a1df829ead ACPI/IORT: Do not blindly trust DMA masks from firmware ... Address issue observed on real world system with suboptimal IORT table where DMA masks of PCI devices would get set to 0 as result. iort_dma_setup() would query the root complex'/named component IORT entry for a DMA mask, and use that over the one the device has been configured with earlier. Ideally we want to use the minimum mask of what the IORT contains for the root complex and what the device was configured with.
