From aba5e278586b16a4fbd377e7e8403aa585d0532a Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 25 Oct 2017 15:39:41 +0100 Subject: drm/i915: Add a hook for making the engines idle (parking) and unparking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In the next patch, we will want to install a callback when the engines (GT as a whole) become idle and similarly when they first become busy. To enable that callback, first rename intel_engines_mark_idle() to intel_engines_park() and provide the companion intel_engines_unpark().
