Subject: [PATCH 04/14] drm/i915/dp: Update the helper intel_dp_needs_as_sdp() for CMRR
Date: Mon, 23 Feb 2026 18:44:16 +0530 [thread overview]
Message-ID: <20260223131426.1638946-5-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20260223131426.1638946-1-ankit.k.nautiyal@intel.com>
AS SDP is supported for both VRR (AVT) and CMRR (FAVT). Update the check
to return true when either VRR or CMRR is enabled.
CMRR is currently disabled in i915, so this change has no functional
impact as of now, but it keeps the logic complete and ready for when CMRR
is enabled.
Subsequent changes will handle AS SDP requirements for Panel Replay.
