- * Contiguous Memory Allocator
- *
- * The Contiguous Memory Allocator (CMA) makes it possible to
- * allocate big contiguous chunks of memory after the system has
- * booted.
- *
- * Why is it needed?
- *
- * Various devices on embedded systems have no scatter-getter and/or
- * IO map support and require contiguous blocks of memory to
- * operate. They include devices such as cameras, hardware video
- * coders, etc.
- *
- * Such devices often require big memory buffers (a full HD frame
- * is, for instance, more then 2 mega pixels large, i.e. more than 6
- * MB of memory), which makes mechanisms such as kmalloc() or
- * alloc_page() ineffective.
- *
- * At the same time, a solution where a big memory region is
- * reserved for a device is suboptimal since often more memory is
- * reserved then strictly required and, moreover, the memory is
- * inaccessible to page system even if device drivers don't use it.
- *
- * CMA tries to solve this issue by operating on memory regions
- * where only movable pages can be allocated from. This way, kernel
- * can use the memory for pagecache and when device driver requests
- * it, allocated pages can be migrated.
- *
- * Driver usage
- *
- * CMA should not be used by the device drivers directly. It is
- * only a helper framework for dma-mapping subsystem.
- *
- * For more information, see kernel-docs in kernel/dma/contiguous.c
