On DCN2, we blank by using +DPG to display a black colour instead of using OTG blank. DPG runs off the +OPP clock, therefore we shouldn't disable the OPP clock when disabling the +plane. We do need to disable the OPP clock when disabling the entire pipe, +that will be addressed in a separate commit. + +Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> +Reviewed-by: Tony Cheng <Tony.Cheng@amd.com> +Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> +Signed-off-by: Alex Deucher <alexander.deucher@amd.com> +--- + drivers/gpu/drm/amd/display/dc/dcn20/dcn20_hwseq.c | 6 ------ + 1 file changed, 6 deletions(-) + +diff --git a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_hwseq.c b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_hwseq.c +index c7ae538611f7..ea56f15a51fb 100644 +--- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_hwseq.c ++++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_hwseq.c +@@ -463,7 +463,6 @@ static void dcn20_plane_atomic_disable(struct dc *dc, struct pipe_ctx *pipe_ctx) + { + struct hubp *hubp = pipe_ctx->plane_res.hubp; + struct dpp *dpp = pipe_ctx->plane_res.dpp; +- int opp_id = hubp->opp_id; + + dc->hwss.wait_for_mpcc_disconnect(dc, dc->res_pool, pipe_ctx); + +@@ -479,11 +478,6 @@ static void dcn20_plane_atomic_disable(struct dc *dc, struct pipe_ctx *pipe_ctx) + + dpp->funcs->dpp_dppclk_control(dpp, false, false); + +- if (opp_id != 0xf && pipe_ctx->stream_res.opp->mpc_tree_params.opp_list == NULL) +- pipe_ctx->stream_res.opp->funcs->opp_pipe_clock_control( +- pipe_ctx->stream_res.opp, +- false); +- + hubp->power_gated = true; + dc->optimized_required = false; /* We're powering off, no need to optimize */ + +-- +2.17.1 + |
