From eac4f1a70772c1480778bae2563199c12634893e Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Fri, 13 Jul 2012 13:59:41 -0700 Subject: i965/blorp: Don't fall back to swrast when miptrees absent. Previously, the blorp engine would fall back to swrast if the source or destination of a blit had no associated miptree. This was unnecessary, since _mesa_BlitFramebufferEXT() already takes care of making the blit silently succeed if there are no buffers bound, so the fallback paths could never actually happen in practice. Removing these fallback paths will simplify the implementation of correct DrawBuffers support in blorp.
