From a2c8327a1b534574d51f5ea42009876e0008efd2 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 9 Sep 2024 17:28:00 +0100 Subject: [PATCH 1346/1350] drm/vc4: Do not include writeback conn load in load tracker The transposer/writeback connector should be running with a lower priority, so shouldn't be factored into the load calculations.
