From 5db346c256bbacc634ff515a1a9202cd4b61d8c7 Mon Sep 17 00:00:00 2001 From: Wenjing Liu Date: Tue, 19 Mar 2024 10:06:51 -0400 Subject: [PATCH] drm/amd/display: update pipe topology log to support subvp [why] There is an ambiguity in subvp pipe topology log. The log doesn't show subvp relation to main stream and it is not clear that certain stream is an internal stream for subvp pipes. [how] Separate subvp pipe topology logging from main pipe topology. Log main stream indices instead of the internal stream for subvp pipes. The following is a sample log showing 2 streams with subvp enabled on both: pipe topology update ________________________ | plane0 slice0 stream0| |DPP1----OPP1----OTG1----| | plane0 slice0 stream1| |DPP0----OPP0----OTG0----| | (phantom pipes) | | plane0 slice0 stream0| |DPP3----OPP3----OTG3----| | plane0 slice0 stream1| |DPP2----OPP2----OTG2----| |________________________| Reviewed-by: Alvin Lee Acked-by: Roman Li Signed-off-by: Wenjing Liu Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher --- .../gpu/drm/amd/display/dc/core/dc_resource.c | 96 +++++++++++++------ 1 file changed, 65 insertions(+), 31 deletions(-) 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 601af21b2df96..c4a3484554b02 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc_resource.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc_resource.c @@ -2193,50 +2193,84 @@ static void resource_log_pipe(struct dc *dc, struct pipe_ctx *pipe, } } -void resource_log_pipe_topology_update(struct dc *dc, struct dc_state *state) +static void resource_log_pipe_for_stream(struct dc *dc, struct dc_state *state, + struct pipe_ctx *otg_master, int stream_idx) { - struct pipe_ctx *otg_master; struct pipe_ctx *opp_heads[MAX_PIPES]; struct pipe_ctx *dpp_pipes[MAX_PIPES]; - int stream_idx, slice_idx, dpp_idx, plane_idx, slice_count, dpp_count; + int slice_idx, dpp_idx, plane_idx, slice_count, dpp_count; bool is_primary; DC_LOGGER_INIT(dc->ctx->logger); + slice_count = resource_get_opp_heads_for_otg_master(otg_master, + &state->res_ctx, opp_heads); + for (slice_idx = 0; slice_idx < slice_count; slice_idx++) { + plane_idx = -1; + if (opp_heads[slice_idx]->plane_state) { + dpp_count = resource_get_dpp_pipes_for_opp_head( + opp_heads[slice_idx], + &state->res_ctx, + dpp_pipes); + for (dpp_idx = 0; dpp_idx < dpp_count; dpp_idx++) { + is_primary = !dpp_pipes[dpp_idx]->top_pipe || + dpp_pipes[dpp_idx]->top_pipe->plane_state != dpp_pipes[dpp_idx]->plane_state; + if (is_primary) + plane_idx++; + resource_log_pipe(dc, dpp_pipes[dpp_idx], + stream_idx, slice_idx, + plane_idx, slice_count, + is_primary); + } + } else { + resource_log_pipe(dc, opp_heads[slice_idx], + stream_idx, slice_idx, plane_idx, + slice_count, true); + } + + } +} + +static int resource_stream_to_stream_idx(struct dc_state *state, + struct dc_stream_state *stream) +{ + int i, stream_idx = -1; + + for (i = 0; i < state->stream_count; i++) + if (state->streams[i] == stream) { + stream_idx = i; + break; + } + return stream_idx; +} + +void resource_log_pipe_topology_update(struct dc *dc, struct dc_state *state) +{ + struct pipe_ctx *otg_master; + int stream_idx, phantom_stream_idx; + DC_LOGGER_INIT(dc->ctx->logger); + DC_LOG_DC(" pipe topology update"); DC_LOG_DC(" ________________________"); for (stream_idx = 0; stream_idx < state->stream_count; stream_idx++) { + if (state->streams[stream_idx]->is_phantom) + continue; + otg_master = resource_get_otg_master_for_stream( &state->res_ctx, state->streams[stream_idx]); - if (!otg_master || otg_master->stream_res.tg == NULL) { - DC_LOG_DC("topology update: otg_master NULL stream_idx %d!\n", stream_idx); - return; - } - slice_count = resource_get_opp_heads_for_otg_master(otg_master, - &state->res_ctx, opp_heads); - for (slice_idx = 0; slice_idx < slice_count; slice_idx++) { - plane_idx = -1; - if (opp_heads[slice_idx]->plane_state) { - dpp_count = resource_get_dpp_pipes_for_opp_head( - opp_heads[slice_idx], - &state->res_ctx, - dpp_pipes); - for (dpp_idx = 0; dpp_idx < dpp_count; dpp_idx++) { - is_primary = !dpp_pipes[dpp_idx]->top_pipe || - dpp_pipes[dpp_idx]->top_pipe->plane_state != dpp_pipes[dpp_idx]->plane_state; - if (is_primary) - plane_idx++; - resource_log_pipe(dc, dpp_pipes[dpp_idx], - stream_idx, slice_idx, - plane_idx, slice_count, - is_primary); - } - } else { - resource_log_pipe(dc, opp_heads[slice_idx], - stream_idx, slice_idx, plane_idx, - slice_count, true); - } + resource_log_pipe_for_stream(dc, state, otg_master, stream_idx); + } + if (state->phantom_stream_count > 0) { + DC_LOG_DC(" | (phantom pipes) |"); + for (stream_idx = 0; stream_idx < state->stream_count; stream_idx++) { + if (state->stream_status[stream_idx].mall_stream_config.type != SUBVP_MAIN) + continue; + phantom_stream_idx = resource_stream_to_stream_idx(state, + state->stream_status[stream_idx].mall_stream_config.paired_stream); + otg_master = resource_get_otg_master_for_stream( + &state->res_ctx, state->streams[phantom_stream_idx]); + resource_log_pipe_for_stream(dc, state, otg_master, stream_idx); } } DC_LOG_DC(" |________________________|\n"); -- 2.30.2
