HSW+ platforms are able to send out HDR Metadata SDP DIP packet as GMP. Hence, extending the support for HDR on DP encoders for the same.
v2: Limited to non eDP ports on hsw/bdw and removed it for lspcon as it is done separately (suggested by Ville) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5389 Cc: Ville Syrjälä <ville.syrj...@linux.intel.com> Signed-off-by: Uma Shankar <uma.shan...@intel.com> --- drivers/gpu/drm/i915/display/intel_dp.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_dp.c b/drivers/gpu/drm/i915/display/intel_dp.c index 9e19165fd175..09382b6133bc 100644 --- a/drivers/gpu/drm/i915/display/intel_dp.c +++ b/drivers/gpu/drm/i915/display/intel_dp.c @@ -4939,10 +4939,12 @@ intel_dp_add_properties(struct intel_dp *intel_dp, struct drm_connector *connect intel_attach_dp_colorspace_property(connector); } - if (IS_GEMINILAKE(dev_priv) || DISPLAY_VER(dev_priv) >= 11) - drm_object_attach_property(&connector->base, - connector->dev->mode_config.hdr_output_metadata_property, - 0); + if (!intel_bios_is_lspcon_present(dev_priv, port)) + if (((IS_HASWELL(dev_priv) || IS_BROADWELL(dev_priv)) && + !intel_dp_is_edp(intel_dp)) || DISPLAY_VER(dev_priv) >= 9) + drm_object_attach_property(&connector->base, + connector->dev->mode_config.hdr_output_metadata_property, + 0); if (intel_dp_is_edp(intel_dp)) { u32 allowed_scalers; -- 2.25.1
