From 37cd85ce3322706d9d357ffbe54481fa884af9e5 Mon Sep 17 00:00:00 2001 From: David Francis Date: Tue, 16 Oct 2018 14:21:32 -0400 Subject: [PATCH] drm/amd/display: Remove dc_stream_state->status [Why] dc_state has an array of dc_stream_status that contain pointers to the dc_plane_state and other useful information Confusingly, dc_stream_state also contains a dc_stream_status called status. This struct was partially initialized and used in a few places [How] stream->status.link has been replaced with stream->sink->link. If a stream does not have a sink, or a sink does not have a link, something has gone seriously wrong All other properties of stream->status were zeroed by kzalloc and never initialized, so they have been replaced by the number 0 This is a refactor: no functional change is intended Signed-off-by: David Francis Reviewed-by: Harry Wentland Acked-by: Bhawanpreet Lakha Acked-by: Tony Cheng Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/core/dc.c | 2 +- drivers/gpu/drm/amd/display/dc/core/dc_stream.c | 2 -- drivers/gpu/drm/amd/display/dc/dc_stream.h | 2 -- drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c | 2 +- 5 files changed, 3 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/core/dc.c b/drivers/gpu/drm/amd/display/dc/core/dc.c index 3279e26..1d8bd55 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc.c @@ -328,7 +328,7 @@ void dc_stream_set_dither_option(struct dc_stream_state *stream, enum dc_dither_option option) { struct bit_depth_reduction_params params; - struct dc_link *link = stream->status.link; + struct dc_link *link = stream->sink->link; struct pipe_ctx *pipes = NULL; int i; diff --git a/drivers/gpu/drm/amd/display/dc/core/dc_stream.c b/drivers/gpu/drm/amd/display/dc/core/dc_stream.c index e113439..780838a 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc_stream.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc_stream.c @@ -100,8 +100,6 @@ static void construct(struct dc_stream_state *stream, /* EDID CAP translation for HDMI 2.0 */ stream->timing.flags.LTE_340MCSC_SCRAMBLE = dc_sink_data->edid_caps.lte_340mcsc_scramble; - stream->status.link = stream->sink->link; - update_stream_signal(stream); stream->out_transfer_func = dc_create_transfer_func(); diff --git a/drivers/gpu/drm/amd/display/dc/dc_stream.h b/drivers/gpu/drm/amd/display/dc/dc_stream.h index c5bd1fb..771d9f1 100644 --- a/drivers/gpu/drm/amd/display/dc/dc_stream.h +++ b/drivers/gpu/drm/amd/display/dc/dc_stream.h @@ -104,8 +104,6 @@ struct dc_stream_state { bool dpms_off; bool apply_edp_fast_boot_optimization; - struct dc_stream_status status; - struct dc_cursor_attributes cursor_attributes; struct dc_cursor_position cursor_position; uint32_t sdr_white_level; // for boosting (SDR) cursor in HDR mode diff --git a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c index 9724a17..2f062ba 100644 --- a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c @@ -2282,7 +2282,7 @@ static void dce110_enable_per_frame_crtc_position_reset( int i; gsl_params.gsl_group = 0; - gsl_params.gsl_master = grouped_pipes[0]->stream->triggered_crtc_reset.event_source->status.primary_otg_inst; + gsl_params.gsl_master = 0; for (i = 0; i < group_size; i++) grouped_pipes[i]->stream_res.tg->funcs->setup_global_swap_lock( diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c index 87495de..6b8a4da 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c @@ -1400,7 +1400,7 @@ static void dcn10_enable_per_frame_crtc_position_reset( if (grouped_pipes[i]->stream_res.tg->funcs->enable_crtc_reset) grouped_pipes[i]->stream_res.tg->funcs->enable_crtc_reset( grouped_pipes[i]->stream_res.tg, - grouped_pipes[i]->stream->triggered_crtc_reset.event_source->status.primary_otg_inst, + 0, &grouped_pipes[i]->stream->triggered_crtc_reset); DC_SYNC_INFO("Waiting for trigger\n"); -- 2.7.4
