Customizing UIO mmap'ing

[Kenneth Adam Miller]

So, previously I think I misunderstood how to use uio_dmem_genirq. Let me
explain the way I think it currently works (bare with me, I departed from
looking at this driver after only about a week of looking at it):

Generally uio_dmem_genirq.c builds on top of uio.c, which provides a common
module basis for isolating code common to the other specific modules. But
for a specific purpose, uio_dmem_genirq.c has be either customized or
extended in order that specific memory regions can be set as accessible.
Most easily, this is done in a first come first serve approach by filling
out the details (which exactly?) left missing in uio_dmem_genirq.c, and to
start, that would be in uio_of_genirq_match

.

Am I correct?
