| Choose this option to enable the system dmabuf heap. The system heap | |
| is backed by pages from the buddy allocator. If in doubt, say Y. | |
| config DMABUF_HEAPS_CMA | |
| bool "DMA-BUF CMA Heap" | |
| depends on DMABUF_HEAPS && DMA_CMA | |
| help | |
| Choose this option to enable dma-buf CMA heap. This heap is backed | |
| by the Contiguous Memory Allocator (CMA). If your system has these | |
| regions, you should say Y here. | |

| help | |
| Add a duplicate CMA-backed dma-buf heap with legacy naming derived | |
| from the CMA area's devicetree node, or "reserved" if the area is not | |
| defined in the devicetree. This uses the same underlying allocator as | |
| CONFIG_DMABUF_HEAPS_CMA. |
