So what you're saying is that we can't currently control the ramp
completely, just give a coefficient and let the hw compute the curve?

You give it a list of pivot points and let he hw interpolate between them.
This should be sufficient for most use cases.


Btw, I've been looking at the register specs. Has any info about semantics
also been released or are there AMD/ATI engineers on standby for this
project?


What are you referring as 'sematics'?
Do you mean programming documentation? No such specs are available.
So far we got by without them to a large extent.
Things on which we needed further information we were able to ask
ATI. However the interface so far has solely been John Bridgman
who has worked his tail off as this is not his only obligation.

From what I have heard a dedicated interface is about to be
established.

Cheers,
Egbert.
