Lines Matching full:area

69  * dma_contiguous_get_area_by_idx() - Get contiguous area at given index
70  * @idx: index of the area we query
72  * Queries for the contiguous area located at index @idx.
75  * A pointer to the requested contiguous area, or NULL otherwise.
89  * Default global CMA area size can be defined in kernel's .config.
95  * Users, who want to set the size of global CMA area for their system
242  * dma_contiguous_reserve() - reserve area(s) for contiguous memory handling

294 		 * We need to insert the new area in our list to avoid  in dma_contiguous_reserve()
295 		 * any inconsistencies between having the default area  in dma_contiguous_reserve()
302 		 * default area yet, and no area in our list.  in dma_contiguous_reserve()
304 		 * This block creates the default area in such a case,  in dma_contiguous_reserve()
306 		 * having a default area but an empty list.  in dma_contiguous_reserve()
322  * dma_contiguous_reserve_area() - reserve custom contiguous area
323  * @size: Size of the reserved area (in bytes),
324  * @base: Base address of the reserved area optional, use 0 for any
327  * @fixed: hint about where to place the reserved area
335  * If @fixed is true, reserve contiguous area at exactly @base.  If false,
357  * dma_alloc_from_contiguous() - allocate pages from contiguous area
364  * device specific contiguous memory area if available or the default
384  * It returns false when provided pages do not belong to contiguous area and
406  * tries to use device specific contiguous memory area if available, or it
411  * global area as the addresses within one page are always contiguous, so
454  * area and true otherwise, this function then does a fallback __free_pages()
