From c5f93fcf2ee1089cdc1c67a8146f81ff26c7c824 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 22 Aug 2017 17:09:14 +0300 Subject: [PATCH] drm/i915: Disable infoframes when shutting down DDI HDMI MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Disabling the video DIP when shutting the port down seems like a good idea. Bspec says: "When disabling both the DIP port and DIP transmission, first disable the port and then disable DIP." and "Restriction : GCP is only supported with HDMI when the bits per color is not equal to 8. GCP must be enabled prior to enabling TRANS_DDI_FUNC_CTL for HDMI with bits per color not equal to 8 and disabled after disabling TRANS_DDI_FUNC_CTL" So let's do it in the .post_disable() hook. v2: Remove double "dpms off" caused by rebase fail Signed-off-by: Ville Syrjälä Reviewed-by: Shashank Sharma Link: https://patchwork.freedesktop.org/patch/msgid/20170822140914.24413-1-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_ddi.c | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_ddi.c b/drivers/gpu/drm/i915/intel_ddi.c index 07ced1044001..b0ff9cf3191c 100644 --- a/drivers/gpu/drm/i915/intel_ddi.c +++ b/drivers/gpu/drm/i915/intel_ddi.c @@ -2211,7 +2211,6 @@ static void intel_ddi_post_disable(struct intel_encoder *intel_encoder, struct drm_i915_private *dev_priv = to_i915(encoder->dev); enum port port = intel_ddi_get_encoder_port(intel_encoder); struct intel_digital_port *dig_port = enc_to_dig_port(encoder); - struct intel_dp *intel_dp = NULL; int type = intel_encoder->type; uint32_t val; bool wait = false; @@ -2219,7 +2218,8 @@ static void intel_ddi_post_disable(struct intel_encoder *intel_encoder, /* old_crtc_state and old_conn_state are NULL when called from DP_MST */ if (type == INTEL_OUTPUT_DP || type == INTEL_OUTPUT_EDP) { - intel_dp = enc_to_intel_dp(encoder); + struct intel_dp *intel_dp = enc_to_intel_dp(encoder); + intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF); } @@ -2238,7 +2238,16 @@ static void intel_ddi_post_disable(struct intel_encoder *intel_encoder, if (wait) intel_wait_ddi_buf_idle(dev_priv, port); - if (intel_dp) { + if (type == INTEL_OUTPUT_HDMI) { + struct intel_hdmi *intel_hdmi = enc_to_intel_hdmi(encoder); + + intel_hdmi->set_infoframes(encoder, false, + old_crtc_state, old_conn_state); + } + + if (type == INTEL_OUTPUT_DP || type == INTEL_OUTPUT_EDP) { + struct intel_dp *intel_dp = enc_to_intel_dp(encoder); + intel_edp_panel_vdd_on(intel_dp); intel_edp_panel_off(intel_dp); } -- 2.11.0
