From 3a5f80e4ce973c6702ec31e5823502860208e030 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Tue, 24 Oct 2023 04:09:24 +0300 Subject: [PATCH] drm/i915/dp_mst: Check BW limitations only after all streams are computed After the previous patch the BW limits on the whole MST topology will be checked after computing the state for all the streams in the topology. Accordingly remove the check during the stream's encoder compute config step, to prevent failing an atomic commit due to a BW limit, if this can be resolved only by reducing the BW of other streams on the same MST link.
