From 30c9b7a1339bd194c63e0b4412037bd577248864 Mon Sep 17 00:00:00 2001 From: Alvin Lee Date: Thu, 12 Dec 2019 16:23:24 -0500 Subject: [PATCH] drm/amd/display: Don't always set pstate true if dummy latency = 0 [Why] If dummy pstate latency is 0 we should report the actual pstate support, and not that pstate is always supported. [How] Don't always program pstate support true Signed-off-by: Alvin Lee Reviewed-by: Jun Lei Acked-by: Harry Wentland Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c index a05746142ec82..eac4c3cecadfb 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c @@ -2918,7 +2918,7 @@ bool dcn20_validate_bandwidth(struct dc *dc, struct dc_state *context, if (context->bw_ctx.dml.soc.dummy_pstate_latency_us == 0 || (voltage_supported && full_pstate_supported)) { - context->bw_ctx.bw.dcn.clk.p_state_change_support = true; + context->bw_ctx.bw.dcn.clk.p_state_change_support = full_pstate_supported; goto restore_dml_state; } -- 2.30.2
