So the bus parameter in iommu_domain_alloc() is no longer relevant. Add a new interface named iommu_paging_domain_alloc(), which explicitly indicates the allocation of a paging domain for DMA managed by a kernel driver. The new interface takes a device pointer as its parameter, that better aligns with the current iommu subsystem.you may want to move this patch before patch 03/04.
Emm, why? Best regards, baolu
