From 8b3478294addc47fb4ae872c95405376c4ac1ecb Mon Sep 17 00:00:00 2001 From: Leo Chen Date: Tue, 11 Apr 2023 10:49:38 -0400 Subject: [PATCH] drm/amd/display: Lowering min Z8 residency time [ Upstream commit d893f39320e1248d1c97fde0d6e51e5ea008a76b ] [Why & How] Per HW team request, we're lowering the minimum Z8 residency time to 2000us. This enables Z8 support for additional modes we were previously blocking like 2k>60hz Cc: stable@vger.kernel.org Tested-by: Daniel Wheeler Reviewed-by: Nicholas Kazlauskas Acked-by: Rodrigo Siqueira Signed-off-by: Leo Chen Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin --- drivers/gpu/drm/amd/display/dc/dcn314/dcn314_resource.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/dc/dcn314/dcn314_resource.c b/drivers/gpu/drm/amd/display/dc/dcn314/dcn314_resource.c index 33d8188d076ab..30129fb9c27a9 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn314/dcn314_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn314/dcn314_resource.c @@ -887,7 +887,7 @@ static const struct dc_plane_cap plane_cap = { static const struct dc_debug_options debug_defaults_drv = { .disable_z10 = false, .enable_z9_disable_interface = true, - .minimum_z8_residency_time = 3080, + .minimum_z8_residency_time = 2000, .psr_skip_crtc_disable = true, .disable_dmcu = true, .force_abm_enable = false, -- 2.39.2
