Before I spend much time digging into the code, I am wondering how much thought on development model and future development has been put into this from AMD perspective. How does AMD envisage development on this going forward, how will AMD internal developement team engage with community development efforts on this code base? How will code come be integrated from the AMD internal codebase into this codebase? How will external contributions be taken into this code base and merged internally? How often will this codebase be updated? every day/week/month/hardware release? Will llvm master eventually be shippable? Will new llvm features be developed in the open? At the moment radv and anv cooperate on developing new features under Khronos, will AMD be open to developing new features internally at Khronos while they are still pre-ratification? Dave.
