Lines Matching full:mappings
35 mappings between physical and bus addresses.
172 The setup for streaming mappings is performed via a call to
214 coherent allocations, but supports full 64-bits for streaming mappings
237 kernel will use this information later when you make DMA mappings.
276 Types of DMA mappings
279 There are two types of DMA mappings:
281 - Consistent DMA mappings which are usually mapped at driver
294 Good examples of what to use consistent mappings for are:
303 versa. Consistent mappings guarantee this.
325 - Streaming DMA mappings which are usually mapped for one DMA
332 Good examples of what to use streaming mappings for are:
340 such mappings you must be explicit about what you want to happen.
348 Using Consistent DMA mappings
475 mappings can be marked with, much like page protections in the user
480 Only streaming mappings specify a direction, consistent mappings
493 Using Streaming DMA mappings
532 Using CPU pointers like this for single mappings has a disadvantage:
