From 7e4e0e5c38493b81cef7e2d6420d85bf783eb73d Mon Sep 17 00:00:00 2001 From: Uma Shankar Date: Thu, 24 Mar 2022 17:34:38 +0530 Subject: [PATCH] drm/i915/display: Extend DP HDR support to hsw+ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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) v3: Added helper and limited eDP restriction to port A (Ville) v4: Dropped some redundant checks (Ville) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5389 Cc: Ville Syrjälä Signed-off-by: Uma Shankar Reviewed-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220324120438.1876445-1-uma.shankar@intel.com --- drivers/gpu/drm/i915/display/intel_dp.c | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_dp.c b/drivers/gpu/drm/i915/display/intel_dp.c index 5e6b134aaa15..6b6dc382be56 100644 --- a/drivers/gpu/drm/i915/display/intel_dp.c +++ b/drivers/gpu/drm/i915/display/intel_dp.c @@ -4887,6 +4887,25 @@ bool intel_dp_is_port_edp(struct drm_i915_private *dev_priv, enum port port) return intel_bios_is_port_edp(dev_priv, port); } +static bool +has_gamut_metadata_dip(struct drm_i915_private *i915, enum port port) +{ + if (intel_bios_is_lspcon_present(i915, port)) + return false; + + if (DISPLAY_VER(i915) >= 11) + return true; + + if (port == PORT_A) + return false; + + if (IS_HASWELL(i915) || IS_BROADWELL(i915) || + DISPLAY_VER(i915) >= 9) + return true; + + return false; +} + static void intel_dp_add_properties(struct intel_dp *intel_dp, struct drm_connector *connector) { @@ -4913,7 +4932,7 @@ 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) + if (has_gamut_metadata_dip(dev_priv, port)) drm_object_attach_property(&connector->base, connector->dev->mode_config.hdr_output_metadata_property, 0); -- GitLab
