It is ./include/linux/dma-contiguous.h:#ifdef CONFIG_CMA ./include/linux/dma-contiguous.h: * There is always at least global CMA area and a few optional device ./include/linux/dma-contiguous.h:#define MAX_CMA_AREAS (1 + CONFIG_CMA_AREAS) ./include/linux/dma-contiguous.h:#define MAX_CMA_AREAS (0) QUESTION: Is CMA planned for non-IVI Tizen? Thank You, Carlos
