From 3e9bc43fbafdd497d475eaffe0deec81b446d122 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 4 Feb 2011 09:07:08 +1000 Subject: r600g: add a flag to just create flushed texture without flushing. This just adds a flag to create the texture without doing any flushing to it. Flushing occurs in the draw function. This avoids unnecessary flushes when we end up rebinding a CB/DB/texture due to the blitter just restoring state.
