This is a note to let you know that I've just added the patch titled drm/msm/dpu: set pdpu->is_rt_pipe early in dpu_plane_sspp_atomic_update() to the 6.2-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-msm-dpu-set-pdpu-is_rt_pipe-early-in-dpu_plane_s.patch and it can be found in the queue-6.2 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 404ceb1c3f234795d83758d6719cafbcc44a7a26 Author: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> Date: Thu Dec 29 21:18:30 2022 +0200 drm/msm/dpu: set pdpu->is_rt_pipe early in dpu_plane_sspp_atomic_update() [ Upstream commit 1d233b1cb149ec78c20fac58331b27bb460f9558 ] The function dpu_plane_sspp_atomic_update() updates pdpu->is_rt_pipe flag, but after the commit 854f6f1c653b ("drm/msm/dpu: update the qos remap only if the client type changes") it sets the flag late, after all the qos functions have updated QoS programming. Move the flag update back to the place where it happened before the mentioned commit to let the pipe be programmed according to its current RT/non-RT state.
