Oh, did I mention we're looking to use a flattened device tree?
That way
we can omit the OF client interface firmware code we currently
load into
domUs. (We could still supply a client interface for other OSs in the
future, if needed, and that code would interpret the flattened tree
itself.)
Using a flat dev tree sure sounds like the easiest approach right now.
But please structure the code (on the Linux side) in such a way that
you could use "real OF" as well, esp. since most of the code to do so
already exists.
hmm, _real_ domain firmware, but since we'd have to magically pass it
stuff about the domain I think we would still use the flattened tree
for that, then the real OF could be booted like linux and then start
with that tree before it modifies that tree before linux actually runs.
I await the XenoSLOF patch :-*
