102 	 * @caching: The current caching state of the pages, see enum
129  * @zero_alloc: true if allocated pages needs to be zeroed
132  * No pages are actually allocated.
142  * @caching: the desired caching state of the pages

187  * ttm_tt_populate - allocate pages for a ttm
193  * Calls the driver method to allocate pages for a ttm
199  * ttm_tt_unpopulate - free pages from a ttm
204  * Calls the driver method to free all pages from a ttm
209  * ttm_tt_mark_for_clear - Mark pages for clearing on populate.
213  * Marks pages for clearing so that the next time the page vector is
214  * populated, the pages will be cleared.
