146 DMA addressing limitations
148 Does your device have any DMA addressing limitations? For example, is
158 support 64-bit addressing (DAC) for all transactions. And at least
164 support the DMA addressing limitation your device has. It is good
212 The standard 32-bit addressing device would do something like this:
220 is to try for 64-bit addressing, but back down to a 32-bit mask that
222 platform is not capable of 64-bit addressing. Rather, it may fail in
223 this case simply because 32-bit addressing is done more efficiently
224 than 64-bit addressing. For example, Sparc64 PCI SAC addressing is
225 more efficient than DAC addressing.
