dma_set_mask_and

函数名称：Set both the DMA mask and the coherent DMA mask to the same thing.* Note that we don't check the return value from dma_set_coherent_mask()* as the DMA API guarantees that the coherent DMA mask can be set to* the same or smaller than the streaming DMA mask.

函数原型：static inline int dma_set_mask_and_coherent(struct device *dev, u64 mask)

返回类型：int

参数：

类型	参数	名称
struct device *	dev
u64	mask

671

rc等于dma_set_mask(dev, mask)

672

如果rc恒等于0则dma_set_coherent_mask(dev, mask)

674

返回:rc

dma_coerce_mask_and_coherent	Similar to the above, except it deals with the case where the device* does not have dev->dma_mask appropriately setup.
