This change was added for dcn30 and dcn301, but not for dcn302 and dcn303 [how] Parse the values from VBIOS if available, and use them if valid Fixes: 93669c8e480dca ("drm/amd/display: get socBB from VBIOS") Signed-off-by: Aurabindo Pillai Reviewed-by: Rodrigo Siqueira Acked-by: Alex Deucher Acked-by: Bindu Ramamurthy Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/display/dc/dcn302/dcn302_resource.c b/drivers/gpu/drm/amd/display/dc/dcn302/dcn302_resource.c index 628b227f0a13a..16a75ba0ca824 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn302/dcn302_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn302/dcn302_resource.c @@ -1102,6 +1102,26 @@ static bool init_soc_bounding_box(struct dc *dc, struct resource_pool *pool) loaded_ip->max_num_dpp = pool->pipe_count; loaded_ip->clamp_min_dcfclk = dc->config.clamp_min_dcfclk; dcn20_patch_bounding_box(dc, loaded_bb); + + if (dc->ctx->dc_bios->funcs->get_soc_bb_info) { + struct bp_soc_bb_info bb_info = { 0 }; + + if (dc->ctx->dc_bios->funcs->get_soc_bb_info( + dc->ctx->dc_bios, &bb_info) == BP_RESULT_OK) { + if (bb_info.dram_clock_change_latency_100ns > 0) + dcn3_02_soc.dram_clock_change_latency_us = + bb_info.dram_clock_change_latency_100ns * 10; + + if (bb_info.dram_sr_enter_exit_latency_100ns > 0) + dcn3_02_soc.sr_enter_plus_exit_time_us = + bb_info.dram_sr_enter_exit_latency_100ns * 10; + + if (bb_info.dram_sr_exit_latency_100ns > 0) + dcn3_02_soc.sr_exit_time_us = + bb_info.dram_sr_exit_latency_100ns * 10; + } + } + return true; } diff --git a/drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c b/drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c index 88b609c32b0ae..34b89464ae022 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c @@ -1028,6 +1028,26 @@ static bool init_soc_bounding_box(struct dc *dc, struct resource_pool *pool) loaded_ip->max_num_dpp = pool->pipe_count; loaded_ip->clamp_min_dcfclk = dc->config.clamp_min_dcfclk; dcn20_patch_bounding_box(dc, loaded_bb); + + if (dc->ctx->dc_bios->funcs->get_soc_bb_info) { + struct bp_soc_bb_info bb_info = { 0 }; + + if (dc->ctx->dc_bios->funcs->get_soc_bb_info( + dc->ctx->dc_bios, &bb_info) == BP_RESULT_OK) { + if (bb_info.dram_clock_change_latency_100ns > 0) + dcn3_03_soc.dram_clock_change_latency_us = + bb_info.dram_clock_change_latency_100ns * 10; + + if (bb_info.dram_sr_enter_exit_latency_100ns > 0) + dcn3_03_soc.sr_enter_plus_exit_time_us = + bb_info.dram_sr_enter_exit_latency_100ns * 10; + + if (bb_info.dram_sr_exit_latency_100ns > 0) + dcn3_03_soc.sr_exit_time_us = + bb_info.dram_sr_exit_latency_100ns * 10; + } + } + return true; }
