How do you generate a scatter/gather list that can be sent to
a PCI DMA bus master?
Not sure what you are asking here, since the precise format of
the scatter/gather list is device dependent. Perhaps you are
wondering how to obtain a physical address from a virtual
address ? If so see mem_offset (in mman.h). If you do a
search in the helviewer with DMA you should get some example
code.
