1257 * the DMA device or a processor and you wish that
1258 * the change be noticed by the master that didn't
1261 * Clearly, only the third case above requires the use of ddi_dma_sync.
1263 * Inquiring minds also want to know which flag to use:
1265 * + If you *modify* with a cpu the object, you use
1266 * ddi_dma_sync(...DDI_DMA_SYNC_FORDEV) (you are making sure
1267 * that the DMA device sees the changes you made).
1269 * + If you are checking, with the processor, an area
1270 * of the object that the DMA device *may* have modified,
1271 * you use ddi_dma_sync(....DDI_DMA_SYNC_FORCPU) (you are
1272 * making sure that the processor(s) will see the changes
