182 For example, if a DMA engine in a device is limited to 32-bit addresses,
190 For example, a device might require 16-byte alignment of its descriptor ring
201 The per-group tags can then inherit these restrictions from this
203 tag rather than having to list them explicitly when creating the per-group tags.

239 Static transactions are used with a long-lived memory region that is reused
285 to track the mappings of any in-flight transactions.
