973 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
974 * is used to align DMA buffers.
977 #include <asm/cache.h>
981 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
982 * stack that meets the minimum architecture alignment requirements for DMA.
983 * Such a buffer is useful for DMA operations where flushing and invalidating
984 * the cache before and after a read and/or write operation is required for
985 * correct operations.
987 * When called the macro creates an array on the stack that is sized such
990 * 1) The beginning of the array can be advanced enough to be aligned.
992 * 2) The size of the aligned portion of the array is a multiple of the minimum
993 * architecture alignment required for DMA.
995 * 3) The aligned portion contains enough space for the original number of
996 * elements requested.
998 * The macro then creates a pointer to the aligned portion of this array and
999 * assigns to the pointer the address of the first element in the aligned
1000 * portion of the array.
1002 * Calling the macro as:
1004 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1006 * Will result in something similar to saying:
1008 * uint32_t buffer[1024];
1010 * The following differences exist:
1012 * 1) The resulting buffer is guaranteed to be aligned to the value of
1013 * ARCH_DMA_MINALIGN.
1015 * 2) The buffer variable created by the macro is a pointer to the specified
1016 * type, and NOT an array of the specified type. This can be very important
1017 * if you want the address of the buffer, which you probably do, to pass it
1018 * to the DMA hardware. The value of &buffer is different in the two cases.
1019 * In the macro case it will be the address of the pointer, not the address
1020 * of the space reserved for the buffer. However, in the second case it
1021 * would be the address of the buffer. So if you are replacing hard coded
1022 * stack buffers with this macro you need to make sure you remove the & from
1023 * the locations where you are taking the address of the buffer.
1025 * Note that the size parameter is the number of array elements to allocate,
1026 * not the number of bytes.
1028 * This macro can not be used outside of function scope, or for the creation
1029 * of a function scoped static buffer. It can not be used to create a cache
1030 * line aligned global buffer.
