This therefore allows the transmision of format information to the sinks which is needed for YUV420 support over DP. Changes in v5: - Slightly modify use of drm_dp_vsc_sdp_pack() - Remove dp_catalog NULL checks - Modify dp_utils_pack_sdp_header() to more clearly pack the header buffer - Move dp_utils_pack_sdp_header() inside of dp_catalog_panel_send_vsc_sdp to clearly show the relationship between the header buffer and the vsc_sdp struct - Due to the last point, remove the dp_utils_pack_vsc_sdp() function and only call drm_dp_vsc_sdp_pack() in dp_panel_setup_vsc_sdp_yuv_420() Changes in v4: - Remove struct msm_dp_sdp_with_parity - Use dp_utils_pack_sdp_header() to pack the SDP header and parity bytes into a buffer - Use this buffer when writing the VSC SDP data in dp_catalog_panel_send_vsc_sdp() - Write to all of the MMSS_DP_GENERIC0 registers instead of just the ones with non-zero values Changes in v3: - Create a new struct, msm_dp_sdp_with_parity, which holds the packing information for VSC SDP - Use drm_dp_vsc_sdp_pack() to pack the data into the new msm_dp_sdp_with_parity struct instead of specifically packing for YUV420 format - Modify dp_catalog_panel_send_vsc_sdp() to send the VSC SDP data using the new msm_dp_sdp_with_parity struct Changes in v2: - Rename GENERIC0_SDPSIZE macro to GENERIC0_SDPSIZE_VALID - Remove dp_sdp from the dp_catalog struct since this data is being allocated at the point used - Create a new function in dp_utils to pack the VSC SDP data into a buffer - Create a new function that packs the SDP header bytes into a buffer. This function is made generic so that it can be utilized by dp_audio header bytes into a buffer - Create a new function in dp_utils that takes the packed buffer and writes to the DP_GENERIC0_* registers - Split the dp_catalog_panel_config_vsc_sdp() function into two to disable/enable sending VSC SDP packets - Check the DP HW version using the original useage of dp_catalog_hw_revision() and correct the version checking logic - Rename dp_panel_setup_vsc_sdp() to dp_panel_setup_vsc_sdp_yuv_420() to explicitly state that currently VSC SDP is only being set up to support YUV420 modes Signed-off-by: Paloma Arellano --- drivers/gpu/drm/msm/dp/dp_catalog.c | 93 +++++++++++++++++++++++++++++ drivers/gpu/drm/msm/dp/dp_catalog.h | 6 ++ drivers/gpu/drm/msm/dp/dp_ctrl.c | 4 ++ drivers/gpu/drm/msm/dp/dp_panel.c | 52 ++++++++++++++++ drivers/gpu/drm/msm/dp/dp_reg.h | 3 + drivers/gpu/drm/msm/dp/dp_utils.c | 25 ++++++++ drivers/gpu/drm/msm/dp/dp_utils.h | 14 +++++ 7 files changed, 197 insertions(+) diff --git a/drivers/gpu/drm/msm/dp/dp_catalog.c b/drivers/gpu/drm/msm/dp/dp_catalog.c index 5d84c089e520a..bfc6f53ae167f 100644 --- a/drivers/gpu/drm/msm/dp/dp_catalog.c +++ b/drivers/gpu/drm/msm/dp/dp_catalog.c @@ -901,6 +901,99 @@ int dp_catalog_panel_timing_cfg(struct dp_catalog *dp_catalog) return 0;

Therefore, let's mark the connector property as true for DP connector when the DP type is not eDP and when there is a CDM block available. Changes in v3: - Move setting the connector's ycbcr_420_allowed parameter so that it is not dependent on if the dp_display is not eDP Changes in v2: - Check for if dp_catalog has a CDM block available instead of checking if VSC SDP is allowed when setting the dp connector's ycbcr_420_allowed parameter Signed-off-by: Paloma Arellano Reviewed-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 4 +++- drivers/gpu/drm/msm/dp/dp_display.c | 4 ++-- drivers/gpu/drm/msm/dp/dp_drm.c | 6 +++++- drivers/gpu/drm/msm/dp/dp_drm.h | 3 ++- drivers/gpu/drm/msm/msm_drv.h | 5 +++-- 5 files changed, 15 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c index 723cc1d821431..8d326fb36550a 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c @@ -565,6 +565,7 @@ static int _dpu_kms_initialize_displayport(struct drm_device *dev, { struct drm_encoder *encoder = NULL; struct msm_display_info info; + bool yuv_supported; int rc; int i; @@ -583,7 +584,8 @@ static int _dpu_kms_initialize_displayport(struct drm_device *dev, return PTR_ERR(encoder); } - rc = msm_dp_modeset_init(priv->dp[i], dev, encoder); + yuv_supported = !!dpu_kms->catalog->cdm; + rc = msm_dp_modeset_init(priv->dp[i], dev, encoder, yuv_supported); if (rc) { DPU_ERROR("modeset_init failed for DP, rc = %d\n", rc); return rc; diff --git a/drivers/gpu/drm/msm/dp/dp_display.c b/drivers/gpu/drm/msm/dp/dp_display.c index b5a67835ce6d1..a435847f1d948 100644 --- a/drivers/gpu/drm/msm/dp/dp_display.c +++ b/drivers/gpu/drm/msm/dp/dp_display.c @@ -1472,7 +1472,7 @@ static int dp_display_get_next_bridge(struct msm_dp *dp) } int msm_dp_modeset_init(struct msm_dp *dp_display, struct drm_device *dev, - struct drm_encoder *encoder) + struct drm_encoder *encoder, bool yuv_supported) { struct dp_display_private *dp_priv; int ret; @@ -1488,7 +1488,7 @@ int msm_dp_modeset_init(struct msm_dp *dp_display, struct drm_device *dev, return ret; } - dp_display->connector = dp_drm_connector_init(dp_display, encoder); + dp_display->connector = dp_drm_connector_init(dp_display, encoder, yuv_supported); if (IS_ERR(dp_display->connector)) { ret = PTR_ERR(dp_display->connector); DRM_DEV_ERROR(dev->dev, diff --git a/drivers/gpu/drm/msm/dp/dp_drm.c b/drivers/gpu/drm/msm/dp/dp_drm.c index 46e6889037e88..a819a4ff76a9f 100644 --- a/drivers/gpu/drm/msm/dp/dp_drm.c +++ b/drivers/gpu/drm/msm/dp/dp_drm.c @@ -353,7 +353,8 @@ int dp_bridge_init(struct msm_dp *dp_display, struct drm_device *dev, } /* connector initialization */ -struct drm_connector *dp_drm_connector_init(struct msm_dp *dp_display, struct drm_encoder *encoder) +struct drm_connector *dp_drm_connector_init(struct msm_dp *dp_display, struct drm_encoder *encoder, + bool yuv_supported) { struct drm_connector *connector = NULL; @@ -364,6 +365,9 @@ struct drm_connector *dp_drm_connector_init(struct msm_dp *dp_display, struct dr if (!dp_display->is_edp) drm_connector_attach_dp_subconnector_property(connector); + if (yuv_supported) + connector->ycbcr_420_allowed = true; + drm_connector_attach_encoder(connector, encoder); return connector; diff --git a/drivers/gpu/drm/msm/dp/dp_drm.h b/drivers/gpu/drm/msm/dp/dp_drm.h index b3d684db2383b..45e57ac25a4d9 100644 --- a/drivers/gpu/drm/msm/dp/dp_drm.h +++ b/drivers/gpu/drm/msm/dp/dp_drm.h @@ -19,7 +19,8 @@ struct msm_dp_bridge { #define to_dp_bridge(x) container_of((x), struct msm_dp_bridge, bridge) -struct drm_connector *dp_drm_connector_init(struct msm_dp *dp_display, struct drm_encoder *encoder); +struct drm_connector *dp_drm_connector_init(struct msm_dp *dp_display, struct drm_encoder *encoder, + bool yuv_supported); int dp_bridge_init(struct msm_dp *dp_display, struct drm_device *dev, struct drm_encoder *encoder); diff --git a/drivers/gpu/drm/msm/msm_drv.h b/drivers/gpu/drm/msm/msm_drv.h index b876ebd48effe..37335777f5c09 100644 --- a/drivers/gpu/drm/msm/msm_drv.h +++ b/drivers/gpu/drm/msm/msm_drv.h @@ -385,7 +385,7 @@ static inline struct drm_dsc_config *msm_dsi_get_dsc_config(struct msm_dsi *msm_ int __init msm_dp_register(void); void __exit msm_dp_unregister(void); int msm_dp_modeset_init(struct msm_dp *dp_display, struct drm_device *dev, - struct drm_encoder *encoder); + struct drm_encoder *encoder, bool yuv_supported); void msm_dp_snapshot(struct msm_disp_state *disp_state, struct msm_dp *dp_display); bool msm_dp_is_yuv_420_enabled(const struct msm_dp *dp_display, const struct drm_display_mode *mode); @@ -403,7 +403,8 @@ static inline void __exit msm_dp_unregister(void) } static inline int msm_dp_modeset_init(struct msm_dp *dp_display, struct drm_device *dev, - struct drm_encoder *encoder) + struct drm_encoder *encoder, + bool yuv_supported) { return -EINVAL; }
