ttm_tt_init
: The struct ttm_tt. : pointer to a struct ttm_bo_device: : Size of the data needed backing. : Page flags as identified by TTM_PAGE_FLAG_XX flags. : See struct ttm_bo_device.
Create a struct ttm_tt to back data with system memory pages. No pages are actually allocated. Returns: NULL: Out of memory.

ttm_tt_set_placement_caching:
A struct ttm_tt the backing pages of which will change caching policy. : Flag indicating the desired caching policy.
This function will change caching policy of any default kernel mappings of the pages backing . If changing from cached to uncached or write-combined, all CPU caches will first be flushed to make sure the data of the pages hit RAM. This function may be very costly as it involves global TLB and cache flushes and potential page splitting / combining.
