Re: Contiguous memory allocator

cma_declare_contiguous() allocates memory from memblock. cma_init_reserved_mem() initialize the memory. Then the memory is given to buddy allocator with migration type MIGRATE_MOVABLE. when CMA needs those pages, it can take it from buddy allocator. We are supposed to use equivalent DMA api dma_declare_contiguous(). dma_declare_contiguous() calls cma_declare_contiguous(). http://lxr.free-electrons.com/source/arch/arm/mach-davinci/devices-da8xx.c#L...
