From 38ff8d2824b7d65577d145114de3b7188fa265ac Mon Sep 17 00:00:00 2001 From: Manasi Navare Date: Fri, 22 Jan 2021 15:26:36 -0800 Subject: drm/i915/display/dp: Do not enable PSR if VRR is enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Even though our HW supports PSR + VRR, the available panels do not work reliably with PSR and VRR together. So if user requested VRR and is supported by HW enable that and do not enable PSR in that case.
