From 8f94d24b7b3191fc8a6cf16c9d815410f5e09ae3 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Thu, 20 Feb 2014 16:01:20 -0800 Subject: [PATCH] drm/i915/bdw: Add FBC support This got lost when we shuffled around our internal branch and GEN7_FEATURES macro. There were no HW changes to support FBC, so we just need to set the flag. v2: Don't allow FBC for any pipe but A on platforms with DDI.
