Subject: [Intel-gfx] [PATCH 01/13] drm/i915/display: Add new member to configure PCON color conversion
Date: Fri, 31 Mar 2023 15:46:01 +0530 [thread overview]
Message-ID: <20230331101613.936776-2-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20230331101613.936776-1-ankit.k.nautiyal@intel.com>
The decision to use DFP output format conversion capabilities should be
during compute_config phase.
This patch adds new member to crtc_state to represent the final
output_format to the sink. In case of a DFP this can be different than
the output_format, as per the format conversion done via the PCON.
This will help to store only the format conversion capabilities of the
DP device in intel_dp->dfp, and use crtc_state to compute and store the
configuration for color/format conversion for a given mode.
v2: modified the new member to crtc_state to represent the final
output_format that eaches the sink, after possible conversion by
PCON kind of devices. (Ville)
v3: Addressed comments from Ville:
-Added comments to clarify difference between sink_format and
output_format.
-Corrected the order of setting sink_format and output_format.
-Added readout for sink_format in get_pipe_config hooks.
v4: Set sink_format for intel_sdvo too. (Ville)
v5: Rebased.
v6: Fixed condition to go for YCbCr420 format for dp and hdmi. (Ville)
v7: Fix the condition to set sink_format for HDMI.
Set hdmi output_format simply as sink_format. (Ville)
