From 29fd17cee17c98c978ff27da29c825cbaf08b9d5 Mon Sep 17 00:00:00 2001 From: Samson Tam Date: Thu, 29 Feb 2024 18:46:04 -0500 Subject: drm/amd/display: clear mpc_tree in init_pipes [Why] During init_pipes, otg master is not initialized. So mpc tree is still configured even if mpc bottom is not active [How] For pipes that have tg enabled, check their mpc tree and clear opp_list if mpc bottom is not active Reviewed-by: George Shen Acked-by: Wayne Lin Signed-off-by: Samson Tam Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/hwss/dcn10/dcn10_hwseq.c | 16 ++++++++++++++++ drivers/gpu/drm/amd/display/dc/hwss/dcn35/dcn35_hwseq.c | 16 ++++++++++++++++ 2 files changed, 32 insertions(+) (limited to 'drivers/gpu/drm/amd/display/dc/hwss') diff --git a/drivers/gpu/drm/amd/display/dc/hwss/dcn10/dcn10_hwseq.c b/drivers/gpu/drm/amd/display/dc/hwss/dcn10/dcn10_hwseq.c index 314798400b16..e0c3c14d12f3 100644 --- a/drivers/gpu/drm/amd/display/dc/hwss/dcn10/dcn10_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/hwss/dcn10/dcn10_hwseq.c @@ -1366,6 +1366,7 @@ void dcn10_init_pipes(struct dc *dc, struct dc_state *context) struct dce_hwseq *hws = dc->hwseq; struct hubbub *hubbub = dc->res_pool->hubbub; bool can_apply_seamless_boot = false; + bool tg_enabled[MAX_PIPES] = {false}; for (i = 0; i < context->stream_count; i++) { if (context->streams[i]->apply_seamless_boot_optimization) { @@ -1447,6 +1448,7 @@ void dcn10_init_pipes(struct dc *dc, struct dc_state *context) // requesting data while in PSR. tg->funcs->tg_init(tg); hubp->power_gated = true; + tg_enabled[i] = true; continue; } @@ -1488,6 +1490,20 @@ void dcn10_init_pipes(struct dc *dc, struct dc_state *context) tg->funcs->tg_init(tg); } + /* Clean up MPC tree */ + for (i = 0; i < dc->res_pool->pipe_count; i++) { + if (tg_enabled[i]) { + if (dc->res_pool->opps[i]->mpc_tree_params.opp_list) { + if (dc->res_pool->opps[i]->mpc_tree_params.opp_list->mpcc_bot) { + int bot_id = dc->res_pool->opps[i]->mpc_tree_params.opp_list->mpcc_bot->mpcc_id; + + if ((bot_id < MAX_MPCC) && (bot_id < MAX_PIPES) && (!tg_enabled[bot_id])) + dc->res_pool->opps[i]->mpc_tree_params.opp_list = NULL; + } + } + } + } + /* Power gate DSCs */ if (hws->funcs.dsc_pg_control != NULL) { uint32_t num_opps = 0; diff --git a/drivers/gpu/drm/amd/display/dc/hwss/dcn35/dcn35_hwseq.c b/drivers/gpu/drm/amd/display/dc/hwss/dcn35/dcn35_hwseq.c index 56b0b6edbee0..2fb90c2330a8 100644 --- a/drivers/gpu/drm/amd/display/dc/hwss/dcn35/dcn35_hwseq.c +++ b/drivers/gpu/drm/amd/display/dc/hwss/dcn35/dcn35_hwseq.c @@ -720,6 +720,7 @@ void dcn35_init_pipes(struct dc *dc, struct dc_state *context) struct hubbub *hubbub = dc->res_pool->hubbub; struct pg_cntl *pg_cntl = dc->res_pool->pg_cntl; bool can_apply_seamless_boot = false; + bool tg_enabled[MAX_PIPES] = {false}; for (i = 0; i < context->stream_count; i++) { if (context->streams[i]->apply_seamless_boot_optimization) { @@ -801,6 +802,7 @@ void dcn35_init_pipes(struct dc *dc, struct dc_state *context) // requesting data while in PSR. tg->funcs->tg_init(tg); hubp->power_gated = true; + tg_enabled[i] = true; continue; } @@ -842,6 +844,20 @@ void dcn35_init_pipes(struct dc *dc, struct dc_state *context) tg->funcs->tg_init(tg); } + /* Clean up MPC tree */ + for (i = 0; i < dc->res_pool->pipe_count; i++) { + if (tg_enabled[i]) { + if (dc->res_pool->opps[i]->mpc_tree_params.opp_list) { + if (dc->res_pool->opps[i]->mpc_tree_params.opp_list->mpcc_bot) { + int bot_id = dc->res_pool->opps[i]->mpc_tree_params.opp_list->mpcc_bot->mpcc_id; + + if ((bot_id < MAX_MPCC) && (bot_id < MAX_PIPES) && (!tg_enabled[bot_id])) + dc->res_pool->opps[i]->mpc_tree_params.opp_list = NULL; + } + } + } + } + if (pg_cntl != NULL) { if (pg_cntl->funcs->dsc_pg_control != NULL) { uint32_t num_opps = 0; -- cgit v1.2.3
