Subject: [Intel-gfx] [PATCH 2/2] drm/i915/vgt: Move VGT GGTT ballooning nodes to i915_ggtt
Date: Sun, 2 Aug 2020 17:34:10 +0200 [thread overview]
Message-ID: <20200802153410.2298-3-michal.wajdeczko@intel.com> (raw)
In-Reply-To: <20200802153410.2298-1-michal.wajdeczko@intel.com>
Since VGT ballooning nodes are GGTT specific, we can move them
to i915_ggtt struct close to some other similar nodes. This way
we drop another place in driver that uses static data.
