865 * ARCH_DMA_MINALIGN is defined in asm/cache.h for each architecture. It
866 * is used to align DMA buffers.
869 #include <asm/cache.h>
873 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
874 * stack that meets the minimum architecture alignment requirements for DMA.
875 * Such a buffer is useful for DMA operations where flushing and invalidating
876 * the cache before and after a read and/or write operation is required for
877 * correct operations.
879 * When called the macro creates an array on the stack that is sized such
882 * 1) The beginning of the array can be advanced enough to be aligned.
884 * 2) The size of the aligned portion of the array is a multiple of the minimum
885 * architecture alignment required for DMA.
887 * 3) The aligned portion contains enough space for the original number of
888 * elements requested.
890 * The macro then creates a pointer to the aligned portion of this array and
891 * assigns to the pointer the address of the first element in the aligned
892 * portion of the array.
894 * Calling the macro as:
896 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
898 * Will result in something similar to saying:
900 * uint32_t buffer[1024];
902 * The following differences exist:
904 * 1) The resulting buffer is guaranteed to be aligned to the value of
907 * 2) The buffer variable created by the macro is a pointer to the specified
908 * type, and NOT an array of the specified type. This can be very important
909 * if you want the address of the buffer, which you probably do, to pass it
910 * to the DMA hardware. The value of &buffer is different in the two cases.
911 * In the macro case it will be the address of the pointer, not the address
912 * of the space reserved for the buffer. However, in the second case it
913 * would be the address of the buffer. So if you are replacing hard coded
914 * stack buffers with this macro you need to make sure you remove the & from
915 * the locations where you are taking the address of the buffer.
917 * Note that the size parameter is the number of array elements to allocate,
918 * not the number of bytes.
920 * This macro can not be used outside of function scope, or for the creation
921 * of a function scoped static buffer. It can not be used to create a cache
922 * line aligned global buffer.
