Author: Dave Airlie <[email protected]> Date: Fri Aug 4 02:13:55 2017 +0100 radv: avoid GPU hangs if someone does a resolve with non-multisample src (v2) This is a bug in the app, but I'd rather avoid hanging the GPU, esp if someone is running in validation and it takes out their development environment. v2: get it right, reverse the polarity.
