You might want to just steal intel_clear.c for the userspace clear path. Bonus points if you actually move it somewhere appropriate in Mesa. sauerbraten's a nice open-source game that works the driver a lot harder than openarena does. When you get to fbos, the gl branch of my cairo tree plus the gl branch of my cairogears tree is mostly memory management and fbo handling right now (until I fix it, then we'll hopefully need a more complicated testcase than gears to actually hit it hard). -- Eric Anholt e...@anholt.net eric.anh...@intel.com
