1226 1226 * the object that any cached references to the object are
1227 1227 * now stale (and flush or invalidate these stale cache references
1228 1228 * as necessary).
1229 1229 *
1230 1230 * The function ddi_dma_sync() provides the general interface with
1231 1231 * respect to this capability. Generally, ddi_dma_free() (below) may
1232 1232 * be used in preference to ddi_dma_sync() as ddi_dma_free() calls
1233 1233 * ddi_dma_sync().
1234 1234 *
1235 1235 * Returns 0 if all caches that exist and are specified by cache_flags
1236 1236 * are successfully operated on, else -1.
1237 1237 *
1238 1238 * The argument offset specifies an offset into the mapping of the mapped
1239 1239 * object in which to perform the synchronization. It will be silently
1240 1240 * truncated to the granularity of underlying cache line sizes as
1241 1241 * appropriate.
1242 1242 *
1243 1243 * The argument len specifies a length starting from offset in which to
1244 1244 * perform the synchronization. A value of (uint_t) -1 means that the length
1245 1245 * proceeds from offset to the end of the mapping. The length argument
1246 1246 * will silently rounded up to the granularity of underlying cache line
1247 1247 * sizes as appropriate.
1248 1248 *
1249 1249 * The argument flags specifies what to synchronize (the device's view of
1250 1250 * the object or the cpu's view of the object).
1251 1251 *
1252 1252 * Inquiring minds want to know when ddi_dma_sync should be used:
1253 1253 *
1254 1254 * + When an object is mapped for dma, assume that an
1255 1255 * implicit ddi_dma_sync() is done for you.
1256 1256 *
1257 1257 * + When an object is unmapped (ddi_dma_free()), assume
1258 1258 * that an implicit ddi_dma_sync() is done for you.
1259 1259 *
1260 1260 * + At any time between the two times above that the
1261 1261 * memory object may have been modified by either
1262 1262 * the DMA device or a processor and you wish that
1263 1263 * the change be noticed by the master that didn't
1264 1264 * do the modifying.
1265 1265 *
1266 1266 * Clearly, only the third case above requires the use of ddi_dma_sync.
1267 1267 *
1268 1268 * Inquiring minds also want to know which flag to use:
1269 1269 *
1270 1270 * + If you *modify* with a cpu the object, you use
1271 1271 * ddi_dma_sync(...DDI_DMA_SYNC_FORDEV) (you are making sure
1272 1272 * that the DMA device sees the changes you made).
1273 1273 *
1274 1274 * + If you are checking, with the processor, an area
1275 1275 * of the object that the DMA device *may* have modified,
1276 1276 * you use ddi_dma_sync(....DDI_DMA_SYNC_FORCPU) (you are
1277 1277 * making sure that the processor(s) will see the changes
1278 1278 * that the DMA device may have made).
