These patches makes the vmwgfx driver use the DMA API to obtain valid device addresses rather than blindly using physical addresses. The main motivation is to be able to use a virtual IOMMU in the future. Other TTM drivers typically map pages one by one rather than using a scatter-gather list, but since we can benefit from having a single dma address region set up by the IOMMU, we use a scatter-gather list instead. Finally to be able to handle all the dma mapping modes, we locally extend the scatter-gather list page iterator to handle also the direct physical- and coherent cases. Finally, the TTM DMA page pool is enabled also when the Intel IOMMU is active ------------------------------------------------------------------------------ Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.
