From d1686ae3ab09a918efa7187cf7e2b2c748c905e1 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 10 Apr 2012 11:41:49 +0100 Subject: [PATCH] drm/i915: Ironlake shares the same video sprite controls as Sandybridge Well, almost. Just a couple of differences, Ironlake lacks a few of the RGB formats, only exposing x8r8g8b8, and lacks a couple of unused features. Given the similarities, we can then reuse the same routines as already written for Sandybridge to enable overlay support for Ironlake as well.
