996 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
997 * is used to align DMA buffers.
1000 #include <asm/cache.h>
1004 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
1005 * stack that meets the minimum architecture alignment requirements for DMA.
1006 * Such a buffer is useful for DMA operations where flushing and invalidating
1007 * the cache before and after a read and/or write operation is required for
1008 * correct operations.
1010 * When called the macro creates an array on the stack that is sized such
1013 * 1) The beginning of the array can be advanced enough to be aligned.
1015 * 2) The size of the aligned portion of the array is a multiple of the minimum
1016 * architecture alignment required for DMA.
1018 * 3) The aligned portion contains enough space for the original number of
1019 * elements requested.
1021 * The macro then creates a pointer to the aligned portion of this array and
1022 * assigns to the pointer the address of the first element in the aligned
1023 * portion of the array.
1025 * Calling the macro as:
1027 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1029 * Will result in something similar to saying:
1031 * uint32_t buffer[1024];
1033 * The following differences exist:
1035 * 1) The resulting buffer is guaranteed to be aligned to the value of
1036 * ARCH_DMA_MINALIGN.
1038 * 2) The buffer variable created by the macro is a pointer to the specified
1039 * type, and NOT an array of the specified type. This can be very important
1040 * if you want the address of the buffer, which you probably do, to pass it
1041 * to the DMA hardware. The value of &buffer is different in the two cases.
1042 * In the macro case it will be the address of the pointer, not the address
1043 * of the space reserved for the buffer. However, in the second case it
1044 * would be the address of the buffer. So if you are replacing hard coded
1045 * stack buffers with this macro you need to make sure you remove the & from
1046 * the locations where you are taking the address of the buffer.
1048 * Note that the size parameter is the number of array elements to allocate,
1049 * not the number of bytes.
1051 * This macro can not be used outside of function scope, or for the creation
1052 * of a function scoped static buffer. It can not be used to create a cache
1053 * line aligned global buffer.
