[PATCH 0/6] map big page by platform IOMMU
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
