Do you have a list of names that you would like included?

I don't know about mesa but the media team have the support in place in 
their internal tree and (as per compute) are waiting for us to push the 
kernel side. This also comes under the headings of both new platforms 
and platforms which are POR for GuC submission. So I believe a lot of 
the UMD side changes for the config table are wrapped up in their 
support for the new platforms/GuC as a whole and thus not yet ready for 
upstream.
