I then installed the AMD driver package again, this time selecting the full install to add the Adrenalin software. 308 AMD Sensor Fusion Hub Driver AMD CIR Driver 103. Hence a properly written Linux driver doesn’t need to be IOMMU-aware: The IOMMU’s address map is updated transparently on calls to dma_map_single() and dma_unmap_single() (and similar functions), so whenever the driver declares a memory region as a DMA buffer for a device, the IOMMU is informed accordingly. System: Windows 10 Windows 10 64-bit While Windows 10 is able to boot, the "AMD IOMMU Device" is absent.
