Lines Matching refs:mappings
35 mappings between physical and bus addresses.
181 The query for streaming mappings is performed via a call to
276 kernel will use this information later when you make DMA mappings.
315 Types of DMA mappings
318 There are two types of DMA mappings:
320 - Consistent DMA mappings which are usually mapped at driver
333 Good examples of what to use consistent mappings for are:
342 versa. Consistent mappings guarantee this.
364 - Streaming DMA mappings which are usually mapped for one DMA
371 Good examples of what to use streaming mappings for are:
379 such mappings you must be explicit about what you want to happen.
387 Using Consistent DMA mappings
515 mappings can be marked with, much like page protections in the user
520 Only streaming mappings specify a direction, consistent mappings
533 Using Streaming DMA mappings
572 Using CPU pointers like this for single mappings has a disadvantage:
