From: Imre Deak Date: Tue, 24 Oct 2023 01:09:24 +0000 (+0300) Subject: drm/i915/dp_mst: Check BW limitations only after all streams are computed X-Git-Tag: v6.8-rc1~21^2~27^2~84 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=3a5f80e4ce973c6702ec31e5823502860208e030;p=linux-2.6-block.git 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.
