From 94a11ddcec9fbd27209da4de7d7c8250c6170f2e Mon Sep 17 00:00:00 2001 From: Vandana Kannan Date: Wed, 11 Jun 2014 11:06:01 +0530 Subject: [PATCH] drm/i915: Add aspect ratio property for HDMI Create and attach the drm property to set aspect ratio. If there is no user specified value, then PAR_NONE/Automatic option is set by default. User can select aspect ratio 4:3 or 16:9. The aspect ratio selected by user would come into effect with a mode set. v2: Modified switch case to include aspect ratio enum changes v3: Modified the patch according the change in the earlier patch to return errno in case property creation fails. With this change, property will be attached only if creation is successful Signed-off-by: Vandana Kannan Cc: Thierry Reding Cc: Daniel Vetter Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_drv.h | 1 + drivers/gpu/drm/i915/intel_hdmi.c | 31 +++++++++++++++++++++++++++++++ 2 files changed, 32 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index 3adcdd1..719f8d2 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -498,6 +498,7 @@ struct intel_hdmi { bool has_audio; enum hdmi_force_audio force_audio; bool rgb_quant_range_selectable; + enum hdmi_picture_aspect aspect_ratio; void (*write_infoframe)(struct drm_encoder *encoder, enum hdmi_infoframe_type type, const void *frame, ssize_t len); diff --git a/drivers/gpu/drm/i915/intel_hdmi.c b/drivers/gpu/drm/i915/intel_hdmi.c index 318b150..228489c 100644 --- a/drivers/gpu/drm/i915/intel_hdmi.c +++ b/drivers/gpu/drm/i915/intel_hdmi.c @@ -367,6 +367,9 @@ static void intel_hdmi_set_avi_infoframe(struct drm_encoder *encoder, union hdmi_infoframe frame; int ret; + /* Set user selected PAR to incoming mode's member */ + adjusted_mode->picture_aspect_ratio = intel_hdmi->aspect_ratio; + ret = drm_hdmi_avi_infoframe_from_display_mode(&frame.avi, adjusted_mode); if (ret < 0) { @@ -1124,6 +1127,23 @@ intel_hdmi_set_property(struct drm_connector *connector, goto done; } + if (property == connector->dev->mode_config.aspect_ratio_property) { + switch (val) { + case DRM_MODE_PICTURE_ASPECT_NONE: + intel_hdmi->aspect_ratio = HDMI_PICTURE_ASPECT_NONE; + break; + case DRM_MODE_PICTURE_ASPECT_4_3: + intel_hdmi->aspect_ratio = HDMI_PICTURE_ASPECT_4_3; + break; + case DRM_MODE_PICTURE_ASPECT_16_9: + intel_hdmi->aspect_ratio = HDMI_PICTURE_ASPECT_16_9; + break; + default: + return -EINVAL; + } + goto done; + } + return -EINVAL; done: @@ -1480,11 +1500,22 @@ static const struct drm_encoder_funcs intel_hdmi_enc_funcs = { }; static void +intel_attach_aspect_ratio_property(struct drm_connector *connector) +{ + if (!drm_mode_create_aspect_ratio_property(connector->dev)) + drm_object_attach_property(&connector->base, + connector->dev->mode_config.aspect_ratio_property, + DRM_MODE_PICTURE_ASPECT_NONE); +} + +static void intel_hdmi_add_properties(struct intel_hdmi *intel_hdmi, struct drm_connector *connector) { intel_attach_force_audio_property(connector); intel_attach_broadcast_rgb_property(connector); intel_hdmi->color_range_auto = true; + intel_attach_aspect_ratio_property(connector); + intel_hdmi->aspect_ratio = HDMI_PICTURE_ASPECT_NONE; } void intel_hdmi_init_connector(struct intel_digital_port *intel_dig_port, -- 2.7.4
