From 121920faf2ccce9aa66a7e2588415c9647b66104 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Mon, 23 Mar 2015 11:10:37 +0000 Subject: [PATCH] drm/i915/skl: Query display address through a wrapper Need to do this in order to support 90/270 rotated display. v2: Pass in drm_plane instead of plane index to intel_obj_display_address. v3: * Renamed intel_obj_display_address to intel_plane_obj_offset. (Chris Wilson) * Simplified rotation check to bitwise AND. (Chris Wilson) v4: * Extracted 90/270 rotation check into a helper function. (Michel Thierry) v5: * Rebased for ggtt view changes.
