From 602a68fbcaa426906a04b7c6d91e9f8140d25939 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:08:05 +0100 Subject: [PATCH] drm/i915: Compartmentalize i915_gem_init_ggtt Continuing on the theme of better logical organization of our code, make the first step towards making the ggtt code better isolated from wider struct drm_i915_private. v2: * Bring the ickle onion unwind back. (Chris) * Rename to i915_init_ggtt.
