| 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. |
| 990 | * |
| 991 | * When called the macro creates an array on the stack that is sized such |
| 992 | * that: |
| 993 | * |
| 994 | * 1) The beginning of the array can be advanced enough to be aligned. |
| 995 | * |
| 996 | * 2) The size of the aligned portion of the array is a multiple of the minimum |
| 997 | * architecture alignment required for DMA. |
| 998 | * |
| 999 | * 3) The aligned portion contains enough space for the original number of |
| 1000 | * elements requested. |
| 1001 | * |
| 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. |
| 1005 | * |
| 1006 | * Calling the macro as: |
| 1007 | * |
| 1008 | * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024); |
| 1009 | * |
| 1010 | * Will result in something similar to saying: |
| 1011 | * |
| 1012 | * uint32_t buffer[1024]; |
| 1013 | * |
| 1014 | * The following differences exist: |
| 1015 | * |
| 1016 | * 1) The resulting buffer is guaranteed to be aligned to the value of |
| 1017 | * ARCH_DMA_MINALIGN. |
| 1018 | * |
| 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. |
| 1028 | * |
| 1029 | * Note that the size parameter is the number of array elements to allocate, |
| 1030 | * not the number of bytes. |
| 1031 | * |
| 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. |
