From 33eef72f8a781b227ba413c453c51e7703a1c481 Mon Sep 17 00:00:00 2001 From: Eric Bernstein Date: Fri, 6 Mar 2020 17:07:12 -0500 Subject: [PATCH] drm/amd/display: Update function to get optimal number of taps [Why] Diagnostics scaling test failing to set required number of vertical taps in 4:2:0 surface case [How] In dpp3_get_optimal_number_of_taps() need to use LB_MEMORY_CONFIG_3 for 4:2:0 surface case. In resource_build_scaling_params() make sure to also set plane res alpha enable based on updated surface state Signed-off-by: Eric Bernstein Reviewed-by: Dmytro Laktyushkin Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/core/dc_resource.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/amd/display/dc/core/dc_resource.c b/drivers/gpu/drm/amd/display/dc/core/dc_resource.c index 75c7ce4..f4bcc71 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc_resource.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc_resource.c @@ -1077,6 +1077,7 @@ bool resource_build_scaling_params(struct pipe_ctx *pipe_ctx) * on certain displays, such as the Sharp 4k */ pipe_ctx->plane_res.scl_data.lb_params.depth = LB_PIXEL_DEPTH_30BPP; + pipe_ctx->plane_res.scl_data.lb_params.alpha_en = plane_state->per_pixel_alpha; pipe_ctx->plane_res.scl_data.recout.x += timing->h_border_left; pipe_ctx->plane_res.scl_data.recout.y += timing->v_border_top; -- 2.7.4
