Subject: [PATCH v4 09/12] drm/i915/dp: Store SDP transmission lines in crtc_state
Date: Thu, 11 Jun 2026 13:03:11 +0530 [thread overview]
Message-ID: <20260611073316.1439306-10-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20260611073316.1439306-1-ankit.k.nautiyal@intel.com>
Currently the driver only programs the transmission line for the
Adaptive-Sync SDP, while the hardware controls the transmission lines for
other SDPs.
Starting with Xe3p_lpd, the hardware allows the driver to program
transmission lines for additional DP SDPs. Prepare for this by adding
fields to struct intel_crtc_state to store SDP transmission lines, and
include them in pipe config comparison.
