Detailed Description

struct ttm_tt

: Pointer to a struct ttm_bo_device. : Pointer to a struct ttm_backend_func that describes the backend methods. : Page to map where the ttm_tt page array contains a NULL pointer. : Array of pages backing the data. : Number of pages in the page array. : Pointer to the current struct ttm_bo_device. : Pointer to the ttm backend. : Pointer to shmem struct file for swap storage. : The current caching state of the pages. : The current binding state of the pages.

This is a structure holding the pages, caching- and aperture binding status for a buffer object that isn't backed by fixed (VRAM / AGP) memory.
