From 0612514db728a28982759e62da3c76444ae15281 Mon Sep 17 00:00:00 2001 From: Mitul Golani Date: Mon, 10 Jun 2024 12:52:00 +0530 Subject: [PATCH] drm/i915/display: Compute Adaptive sync SDP params Compute params for Adaptive Sync SDP when Fixed Average Vtotal mode is enabled. --v2: Since vrr.enable is set in case of cmrr also, handle accordingly(Ankit). --v3: - Since vrr.enable is set in case of cmrr also, handle accordingly(Ankit). - check cmrr.enable when CMRR flags are set during intel_dp_compute_as_sdp. --v4: - Use drm_mode_vrefresh instead of manual calculation (Ankit).
