Hi, Generally the the imported buffers which has memory type TTM_PL_TT are mapped as small pages probably due to lack of big page allocation. But the platform device which also use memory type TTM_PL_TT, like GK20A, can *allocate* big page though the IOMMU hardware inside the SoC. This is a try to map the imported buffers as big pages in GMMU by the platform IOMMU. With some preparation work to
