From 64d8b7806e40a1520d5eb47157ff4ee15efc3bf6 Mon Sep 17 00:00:00 2001 From: Shirish S Date: Thu, 23 Mar 2017 14:54:40 +0530 Subject: drm/amd/display: update plane functionalities This patch introduces amdgpu_drm_plane_state structure, which subclasses drm_plane_state and holds data suitable for configuring hardware. It switches reset(), atomic_duplicate_state() & atomic_destroy_state() functions to new internal implementation, earlier they were pointing to drm core functions. TESTS(On Chromium OS on Stoney Only) * Builds without compilation errors. * 'plane_test' passes for XR24 format based Overlay plane. * Chromium OS ui comes up.
