/*
|
|
* The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
|
|
* stack that meets the minimum architecture alignment requirements for DMA.
|
|
* Such a buffer is useful for DMA operations where flushing and invalidating
|
|
* the cache before and after a read and/or write operation is required for
|
|
* correct operations.
|
|
*
|
|
* When called the macro creates an array on the stack that is sized such
|
|
* that:
|
|
*
|
|
* 1) The beginning of the array can be advanced enough to be aligned.
|
|
*
|
|
* 2) The size of the aligned portion of the array is a multiple of the minimum
|
|
* architecture alignment required for DMA.
|
|
*
|
|
* 3) The aligned portion contains enough space for the original number of
|
|
* elements requested.
|
|
*
|
|
* The macro then creates a pointer to the aligned portion of this array and
|
|
* assigns to the pointer the address of the first element in the aligned
|
|
* portion of the array.
|
|
*
|
|
* Calling the macro as:
|
|
*
|
|
* ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
|
|
*
|
|
* Will result in something similar to saying:
|
|
*
|
|
* uint32_t buffer[1024];
|
|
*
|
|
* The following differences exist:
|
|
*
|
|
* 1) The resulting buffer is guaranteed to be aligned to the value of
|
|
* ARCH_DMA_MINALIGN.
|
|
*
|
|
* 2) The buffer variable created by the macro is a pointer to the specified
|
|
* type, and NOT an array of the specified type. This can be very important
|
|
* if you want the address of the buffer, which you probably do, to pass it
|
|
* to the DMA hardware. The value of &buffer is different in the two cases.
|
|
* In the macro case it will be the address of the pointer, not the address
|
|
* of the space reserved for the buffer. However, in the second case it
|
|
* would be the address of the buffer. So if you are replacing hard coded
|
|
* stack buffers with this macro you need to make sure you remove the & from
|
|
* the locations where you are taking the address of the buffer.
|
|
*
|
|
* Note that the size parameter is the number of array elements to allocate,
|
|
* not the number of bytes.
|
|
*
|
|
* This macro can not be used outside of function scope, or for the creation
|
|
* of a function scoped static buffer. It can not be used to create a cache
|
|
* line aligned global buffer.
