1001 | /* |
1002 | * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the | |
1003 | * stack that meets the minimum architecture alignment requirements for DMA. | |
1004 | * Such a buffer is useful for DMA operations where flushing and invalidating | |
1005 | * the cache before and after a read and/or write operation is required for | |
1006 | * correct operations. | |
1007 | * | |
1008 | * When called the macro creates an array on the stack that is sized such | |
1009 | * that: | |
1010 | * | |
1011 | * 1) The beginning of the array can be advanced enough to be aligned. | |
1012 | * | |
1013 | * 2) The size of the aligned portion of the array is a multiple of the minimum | |
1014 | * architecture alignment required for DMA. | |
1015 | * | |
1016 | * 3) The aligned portion contains enough space for the original number of | |
1017 | * elements requested. | |
1018 | * | |
1019 | * The macro then creates a pointer to the aligned portion of this array and | |
1020 | * assigns to the pointer the address of the first element in the aligned | |
1021 | * portion of the array. | |
1022 | * | |
1023 | * Calling the macro as: | |
1024 | * | |
1025 | * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024); | |
1026 | * | |
1027 | * Will result in something similar to saying: | |
1028 | * | |
1029 | * uint32_t buffer[1024]; | |
1030 | * | |
1031 | * The following differences exist: | |
1032 | * | |
1033 | * 1) The resulting buffer is guaranteed to be aligned to the value of | |
1034 | * ARCH_DMA_MINALIGN. | |
1035 | * | |
1036 | * 2) The buffer variable created by the macro is a pointer to the specified | |
1037 | * type, and NOT an array of the specified type. This can be very important | |
1038 | * if you want the address of the buffer, which you probably do, to pass it | |
1039 | * to the DMA hardware. The value of &buffer is different in the two cases. | |
1040 | * In the macro case it will be the address of the pointer, not the address | |
1041 | * of the space reserved for the buffer. However, in the second case it | |
1042 | * would be the address of the buffer. So if you are replacing hard coded | |
1043 | * stack buffers with this macro you need to make sure you remove the & from | |
1044 | * the locations where you are taking the address of the buffer. | |
1045 | * | |
1046 | * Note that the size parameter is the number of array elements to allocate, | |
1047 | * not the number of bytes. | |
1048 | * | |
1049 | * This macro can not be used outside of function scope, or for the creation | |
1050 | * of a function scoped static buffer. It can not be used to create a cache | |
1051 | * line aligned global buffer. | |
