974 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
975 * is used to align DMA buffers.
978 #include <asm/cache.h>
982 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
983 * stack that meets the minimum architecture alignment requirements for DMA.
984 * Such a buffer is useful for DMA operations where flushing and invalidating
985 * the cache before and after a read and/or write operation is required for
986 * correct operations.
988 * When called the macro creates an array on the stack that is sized such
991 * 1) The beginning of the array can be advanced enough to be aligned.
993 * 2) The size of the aligned portion of the array is a multiple of the minimum
994 * architecture alignment required for DMA.
996 * 3) The aligned portion contains enough space for the original number of
997 * elements requested.
999 * The macro then creates a pointer to the aligned portion of this array and
1000 * assigns to the pointer the address of the first element in the aligned
1001 * portion of the array.
1003 * Calling the macro as:
1005 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1007 * Will result in something similar to saying:
1009 * uint32_t buffer[1024];
1011 * The following differences exist:
1013 * 1) The resulting buffer is guaranteed to be aligned to the value of
1014 * ARCH_DMA_MINALIGN.
1016 * 2) The buffer variable created by the macro is a pointer to the specified
1017 * type, and NOT an array of the specified type. This can be very important
1018 * if you want the address of the buffer, which you probably do, to pass it
1019 * to the DMA hardware. The value of &buffer is different in the two cases.
1020 * In the macro case it will be the address of the pointer, not the address
1021 * of the space reserved for the buffer. However, in the second case it
1022 * would be the address of the buffer. So if you are replacing hard coded
1023 * stack buffers with this macro you need to make sure you remove the & from
1024 * the locations where you are taking the address of the buffer.
1026 * Note that the size parameter is the number of array elements to allocate,
1027 * not the number of bytes.
1029 * This macro can not be used outside of function scope, or for the creation
1030 * of a function scoped static buffer. It can not be used to create a cache
1031 * line aligned global buffer.
