Hi.
I am new to the Linux DMA APIs.
First, I started by reading Documentation/DMA-API.txt,
but I am confused with the term "consistent memory".
Just read "coherent memory" instead - the documentation confusingly uses
the two terms to refer to the same thing. I think there was a patch a
while back to replace "consistent" with "coherent" in this document,
though I'm not sure what happened to it.
I wrote that patch. I never got any comments on it, so either I didn't
post it to the right people, or no one really cares:
http://www.kernelhub.org/?msg=747166&p=2
I still think that if the kernel methods all have "coherent" in their
name, we should use the word "coherent" in the documentation as well,
and not confuse people even further. So I'd happily repost that patch.
