At the moment the decoder can't distinguish instructions which share the same opcode between the render and video pipe, and thus aubinator outputs garbage on media instructions. I was reluctant to make these changes into Mesa in the first place since the work is related to media, not 3d, but as aubinator is now located here, here we are. </blockquote><div> </div><div>That's fine.

Put these in Mesa as aubinator now resides here instead of IGT. a) Put all instruction definitions in the current genxml files, be it with a tag or an attribute, both methods have their advantages and disadvantages. b) Separate genxml files into common, render and video (and blitter?) 2. Fork aubinator tools and related genxml infra to a completely separate project. If I have missed an option, feel free to suggest. </blockquote><div> </div><div>I wasn't suggesting we fork the tools and the XML.
