| bool "DMA-BUF System Heap" |
| depends on DMABUF_HEAPS |
| help |
| 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. |

| config DMABUF_HEAPS_CMA_LEGACY |
| bool "Legacy DMA-BUF CMA Heap" |
| default y |
| depends on DMABUF_HEAPS_CMA |
| 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. |
