977 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
978 * is used to align DMA buffers.
981 #include <asm/cache.h>
985 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
986 * stack that meets the minimum architecture alignment requirements for DMA.
987 * Such a buffer is useful for DMA operations where flushing and invalidating
988 * the cache before and after a read and/or write operation is required for
989 * correct operations.
991 * When called the macro creates an array on the stack that is sized such
994 * 1) The beginning of the array can be advanced enough to be aligned.
996 * 2) The size of the aligned portion of the array is a multiple of the minimum
997 * architecture alignment required for DMA.
999 * 3) The aligned portion contains enough space for the original number of
1000 * elements requested.
1002 * The macro then creates a pointer to the aligned portion of this array and
1003 * assigns to the pointer the address of the first element in the aligned
1004 * portion of the array.
1006 * Calling the macro as:
1008 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1010 * Will result in something similar to saying:
1012 * uint32_t buffer[1024];
1014 * The following differences exist:
1016 * 1) The resulting buffer is guaranteed to be aligned to the value of
1017 * ARCH_DMA_MINALIGN.
1019 * 2) The buffer variable created by the macro is a pointer to the specified
1020 * type, and NOT an array of the specified type. This can be very important
1021 * if you want the address of the buffer, which you probably do, to pass it
1022 * to the DMA hardware. The value of &buffer is different in the two cases.
1023 * In the macro case it will be the address of the pointer, not the address
1024 * of the space reserved for the buffer. However, in the second case it
1025 * would be the address of the buffer. So if you are replacing hard coded
1026 * stack buffers with this macro you need to make sure you remove the & from
1027 * the locations where you are taking the address of the buffer.
1029 * Note that the size parameter is the number of array elements to allocate,
1030 * not the number of bytes.
1032 * This macro can not be used outside of function scope, or for the creation
1033 * of a function scoped static buffer. It can not be used to create a cache
1034 * line aligned global buffer.
