33 mappings between physical and bus addresses.
177 The query for streaming mappings is performed via a call to
272 kernel will use this information later when you make DMA mappings.
311 Types of DMA mappings
313 There are two types of DMA mappings:
315 - Consistent DMA mappings which are usually mapped at driver
328 Good examples of what to use consistent mappings for are:
337 versa. Consistent mappings guarantee this.
357 - Streaming DMA mappings which are usually mapped for one DMA
364 Good examples of what to use streaming mappings for are:
372 such mappings you must be explicit about what you want to happen.
380 Using Consistent DMA mappings.
506 mappings can be marked with, much like page protections in the user
511 Only streaming mappings specify a direction, consistent mappings
524 Using Streaming DMA mappings
583 Using CPU pointers like this for single mappings has a disadvantage:
