No, I'm not. I'm saying configuration specific to a machine, if there is any, 
needs to be in the BSP layer for that machine. Whether the maintainer of that 
BSP or some external contributor provides and maintains that is a separate 
question.

If there are clutter tests we can run on the Yocto Project reference hardware 
platforms (which I understand from Bruce may be refreshed for 1.5) and they 
could be run in an automated manner, we can run these on the autobuilder and 
this will help prove the functionality of clutter itself. Once the tests are 
set up it should be easy for others to run these regularly on their own 
autobuilders with other BSPs.

First you say there are hardware specific bits, then you say there aren't any 
changes required. I'm not following at all.

Sorry, but I don't think the important questions have been answered yet.

Cheers,
