895 | /* |
896 | * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the | |
897 | * stack that meets the minimum architecture alignment requirements for DMA. | |
898 | * Such a buffer is useful for DMA operations where flushing and invalidating | |
899 | * the cache before and after a read and/or write operation is required for | |
900 | * correct operations. | |
901 | * | |
902 | * When called the macro creates an array on the stack that is sized such | |
903 | * that: | |
904 | * | |
905 | * 1) The beginning of the array can be advanced enough to be aligned. | |
906 | * | |
907 | * 2) The size of the aligned portion of the array is a multiple of the minimum | |
908 | * architecture alignment required for DMA. | |
909 | * | |
910 | * 3) The aligned portion contains enough space for the original number of | |
911 | * elements requested. | |
912 | * | |
913 | * The macro then creates a pointer to the aligned portion of this array and | |
914 | * assigns to the pointer the address of the first element in the aligned | |
915 | * portion of the array. | |
916 | * | |
917 | * Calling the macro as: | |
918 | * | |
919 | * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024); | |
920 | * | |
921 | * Will result in something similar to saying: | |
922 | * | |
923 | * uint32_t buffer[1024]; | |
924 | * | |
925 | * The following differences exist: | |
926 | * | |
927 | * 1) The resulting buffer is guaranteed to be aligned to the value of | |
928 | * ARCH_DMA_MINALIGN. | |
929 | * | |
930 | * 2) The buffer variable created by the macro is a pointer to the specified | |
931 | * type, and NOT an array of the specified type. This can be very important | |
932 | * if you want the address of the buffer, which you probably do, to pass it | |
933 | * to the DMA hardware. The value of &buffer is different in the two cases. | |
934 | * In the macro case it will be the address of the pointer, not the address | |
935 | * of the space reserved for the buffer. However, in the second case it | |
936 | * would be the address of the buffer. So if you are replacing hard coded | |
937 | * stack buffers with this macro you need to make sure you remove the & from | |
938 | * the locations where you are taking the address of the buffer. | |
939 | * | |
940 | * Note that the size parameter is the number of array elements to allocate, | |
941 | * not the number of bytes. | |
942 | * | |
943 | * This macro can not be used outside of function scope, or for the creation | |
944 | * of a function scoped static buffer. It can not be used to create a cache | |
945 | * line aligned global buffer. | |
