From 0fbe7870d7e97d6fa595652a8f8eaf159e4bb6c9 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 7 Nov 2013 11:05:44 +0100 Subject: [PATCH] drm/i915: Wire up pipe CRC support for bdw MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The layout of the CRC registers is the same as on hsw, only the interrupt handling has changed a bit. So trivial to wire up, yay!
