I'm not sure I really follow what you're saying so, I'll restate what 
I'm saying.

The values that you can set on the TPG from userspace via yavta should 
be the same names/values when talking to the CSID version as the TPG 
version.

Just looking at the list of strings, I think omitting the Reserved 
pretty much does that.

But you certainly shouldn't have one set of strings for the CSID-TPG and 
the dedicated TPG which produce the same test patterns, no matter how 
its implemented under the hood.
