From eec3d5efd16d13984a88396b685ae17462fb6d87 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Date: Thu, 28 Feb 2019 12:57:59 -0500 Subject: [PATCH] drm/amd/display: Reset alpha state for planes to the correct values [Why] The plane_reset callback is subclassed but hasn't been updated since the drm helper got updated to include resetting alpha related state (state->alpha and state->pixel_blend_mode). The overlay planes exposed by amdgpu_dm were therefore being rendered as invisible by default ever since supported was exposed for alpha blending properties on overlays. This caused regressions in igt@kms_plane_multiple@atomic-tiling-none and igt@kms_plane@plane-position-covered-pipe tests. [How] Reset the plane state values to their correct values as defined in the drm helper. This fixes the IGT test regression.
