From bb65a1d009e3d8398492aa30d944c17a40535aa1 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 8 Feb 2010 11:21:29 -0800 Subject: intel: Expose a minimal number of configs with accumulation buffer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Expose one config per color depth that includes accumulation buffer. We could probably expose only one config with accumulation buffer, but that would require figuring out the actual color depth. This is easier and only exposes 2 useless configs.
