...bly 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 map decreate small pages into big page(s) by IOMMU the GMMU eventually sees the imported buffer as chunks of big pages and does the mapping. And then we can probably do the compression on teh imported buffer which is composed of non-contiguous small pages. The compbits related patches shall come later. I guess...
