We should only assign intel_dma_ops to devices which will actually use the iommu and let the default fall back dma_direct_* functions handle all other devices. This won't change any behaviour but will just use the generic implementations for direct mapped devices rather than intel specific ones.

...t now* for debugging my Arm DMA ops series, so if I'm going to hack something up anyway I may as well take responsibility for polishing it into a proper patch as well :) Robin. > > Tom Murphy (8): > iommu/vt-d: clean up 32bit si_domain assignment > iommu/vt-d: Use default dma_direct_* mapping functions for direct > mapped devices > iommu/vt-d: Remove IOVA handling code from non-dma_ops path > iommu: Handle freelists when using deferred flushing in iommu drivers > iommu: Add iommu_dma_free_cpu_cached_iovas function > iommu: allow the dma-iommu api...

...and reimplemented in the dma-iommu path. I would like to take the time to do this but I really don?t have the time at the moment and I want to get these changes out before the iommu code changes any more.

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. I'm still a
