1227 1229 * The argument offset specifies an offset into the mapping of the mapped
1228 1230 * object in which to perform the synchronization. It will be silently
1229 1231 * truncated to the granularity of underlying cache line sizes as
1230 1232 * appropriate.
1231 1233 *
1232 1234 * The argument len specifies a length starting from offset in which to
1233 1235 * perform the synchronization. A value of (uint_t) -1 means that the length
1234 1236 * proceeds from offset to the end of the mapping. The length argument
1235 1237 * will silently rounded up to the granularity of underlying cache line
1236 1238 * sizes as appropriate.
1237 1239 *
1238 1240 * The argument flags specifies what to synchronize (the device's view of
1239 1241 * the object or the cpu's view of the object).
1240 1242 *
1241 1243 * Inquiring minds want to know when ddi_dma_sync should be used:
1242 1244 *
1243 1245 * + When an object is mapped for dma, assume that an
1244 1246 * implicit ddi_dma_sync() is done for you.
1245 1247 *
1246 1248 * + When an object is unmapped (ddi_dma_free()), assume
1247 1249 * that an implicit ddi_dma_sync() is done for you.
1248 1250 *
1249 1251 * + At any time between the two times above that the
1250 1252 * memory object may have been modified by either
1251 1253 * the DMA device or a processor and you wish that
1252 1254 * the change be noticed by the master that didn't
1253 1255 * do the modifying.
1254 1256 *
1255 1257 * Clearly, only the third case above requires the use of ddi_dma_sync.
1256 1258 *
1257 1259 * Inquiring minds also want to know which flag to use:
1258 1260 *
1259 1261 * + If you *modify* with a cpu the object, you use
1260 1262 * ddi_dma_sync(...DDI_DMA_SYNC_FORDEV) (you are making sure
1261 1263 * that the DMA device sees the changes you made).
1262 1264 *
1263 1265 * + If you are checking, with the processor, an area
1264 1266 * of the object that the DMA device *may* have modified,
1265 1267 * you use ddi_dma_sync(....DDI_DMA_SYNC_FORCPU) (you are
1266 1268 * making sure that the processor(s) will see the changes
1267 1269 * that the DMA device may have made).
