From: Vandana Kannan <[email protected]> The eDP WA to stop link train based on port type is for HSW/BDW, not required for SKL+. Suggested by Satheesh
v2: Simplified the check befoe stop_link_train. Suggested by Satheesh. v3: stop_link_train need not be called from intel_enable_ddi for gen >= 9 Suggested-by: Satheeshakrishna M <[email protected]> Reviewed-by: Satheeshakrishna M <[email protected]> Signed-off-by: Vandana Kannan <[email protected]> Cc: Satheeshakrishna M <[email protected]> Signed-off-by: Damien Lespiau <[email protected]> --- drivers/gpu/drm/i915/intel_ddi.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_ddi.c b/drivers/gpu/drm/i915/intel_ddi.c index f68e04c..2561b40 100644 --- a/drivers/gpu/drm/i915/intel_ddi.c +++ b/drivers/gpu/drm/i915/intel_ddi.c @@ -1491,7 +1491,7 @@ static void intel_ddi_pre_enable(struct intel_encoder *intel_encoder) intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON); intel_dp_start_link_train(intel_dp); intel_dp_complete_link_train(intel_dp); - if (port != PORT_A) + if (port != PORT_A || INTEL_INFO(dev)->gen >= 9) intel_dp_stop_link_train(intel_dp); } else if (type == INTEL_OUTPUT_HDMI) { struct intel_hdmi *intel_hdmi = enc_to_intel_hdmi(encoder); @@ -1567,7 +1567,7 @@ static void intel_enable_ddi(struct intel_encoder *intel_encoder) } else if (type == INTEL_OUTPUT_EDP) { struct intel_dp *intel_dp = enc_to_intel_dp(encoder); - if (port == PORT_A) + if (port == PORT_A && INTEL_INFO(dev)->gen < 9) intel_dp_stop_link_train(intel_dp); intel_edp_backlight_on(intel_dp); -- 1.8.3.1 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
