891 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
892 * is used to align DMA buffers.
895 #include <asm/cache.h>
899 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
900 * stack that meets the minimum architecture alignment requirements for DMA.
901 * Such a buffer is useful for DMA operations where flushing and invalidating
902 * the cache before and after a read and/or write operation is required for
903 * correct operations.
905 * When called the macro creates an array on the stack that is sized such
908 * 1) The beginning of the array can be advanced enough to be aligned.
910 * 2) The size of the aligned portion of the array is a multiple of the minimum
911 * architecture alignment required for DMA.
913 * 3) The aligned portion contains enough space for the original number of
914 * elements requested.
916 * The macro then creates a pointer to the aligned portion of this array and
917 * assigns to the pointer the address of the first element in the aligned
918 * portion of the array.
920 * Calling the macro as:
922 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
924 * Will result in something similar to saying:
926 * uint32_t buffer[1024];
928 * The following differences exist:
930 * 1) The resulting buffer is guaranteed to be aligned to the value of
933 * 2) The buffer variable created by the macro is a pointer to the specified
934 * type, and NOT an array of the specified type. This can be very important
935 * if you want the address of the buffer, which you probably do, to pass it
936 * to the DMA hardware. The value of &buffer is different in the two cases.
937 * In the macro case it will be the address of the pointer, not the address
938 * of the space reserved for the buffer. However, in the second case it
939 * would be the address of the buffer. So if you are replacing hard coded
940 * stack buffers with this macro you need to make sure you remove the & from
941 * the locations where you are taking the address of the buffer.
943 * Note that the size parameter is the number of array elements to allocate,
944 * not the number of bytes.
946 * This macro can not be used outside of function scope, or for the creation
947 * of a function scoped static buffer. It can not be used to create a cache
948 * line aligned global buffer.
