149 DMA addressing limitations
152 Does your device have any DMA addressing limitations? For example, is
162 support 64-bit addressing (DAC) for all transactions. And at least
168 support the DMA addressing limitation your device has. It is good
216 The standard 32-bit addressing device would do something like this::
224 is to try for 64-bit addressing, but back down to a 32-bit mask that
226 platform is not capable of 64-bit addressing. Rather, it may fail in
227 this case simply because 32-bit addressing is done more efficiently
228 than 64-bit addressing. For example, Sparc64 PCI SAC addressing is
229 more efficient than DAC addressing.
