927 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
928 * is used to align DMA buffers.
931 #include <asm/cache.h>
935 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
936 * stack that meets the minimum architecture alignment requirements for DMA.
937 * Such a buffer is useful for DMA operations where flushing and invalidating
938 * the cache before and after a read and/or write operation is required for
939 * correct operations.
941 * When called the macro creates an array on the stack that is sized such
944 * 1) The beginning of the array can be advanced enough to be aligned.
946 * 2) The size of the aligned portion of the array is a multiple of the minimum
947 * architecture alignment required for DMA.
949 * 3) The aligned portion contains enough space for the original number of
950 * elements requested.
952 * The macro then creates a pointer to the aligned portion of this array and
953 * assigns to the pointer the address of the first element in the aligned
954 * portion of the array.
956 * Calling the macro as:
958 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
960 * Will result in something similar to saying:
962 * uint32_t buffer[1024];
964 * The following differences exist:
966 * 1) The resulting buffer is guaranteed to be aligned to the value of
969 * 2) The buffer variable created by the macro is a pointer to the specified
970 * type, and NOT an array of the specified type. This can be very important
971 * if you want the address of the buffer, which you probably do, to pass it
972 * to the DMA hardware. The value of &buffer is different in the two cases.
973 * In the macro case it will be the address of the pointer, not the address
974 * of the space reserved for the buffer. However, in the second case it
975 * would be the address of the buffer. So if you are replacing hard coded
976 * stack buffers with this macro you need to make sure you remove the & from
977 * the locations where you are taking the address of the buffer.
979 * Note that the size parameter is the number of array elements to allocate,
980 * not the number of bytes.
982 * This macro can not be used outside of function scope, or for the creation
983 * of a function scoped static buffer. It can not be used to create a cache
984 * line aligned global buffer.
