From 35a57ffbb10840af219eeaf64718434242bb7c76 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 20 Nov 2014 00:33:07 +0100 Subject: drm/i915: Only init engines once We can do this. And now there's finally the clean split between software setup and hardware setup I kinda wanted since multi-ring support was merged aeons ago. It only took almost 5 years.
