This regression is already part of the 6.3 stable release series. Will the new patch qualify for inclusion in 6.3.y? Or will it be part of 6.4 and this revert should go into 6.3.y? Even with this revert, there are additional regressions in 6.3 causing dpu errors and blank external display upon suspending and resuming the system while an external display is connected. Will your new patch also fix these regressions?

Hi Kuogee, thank you. Verified the v6 patch fixes the regression when ported to 6.3.3. One non-fatal issue remains: Suspending and resuming the system while USB-C DP monitor is connected triggers an error, though the system recovers within a second without the need to unplug the cable.

Thank you for checking with sc7280. I created https://gitlab.freedesktop.org/drm/msm/-/issues/25 and CCed you. I've also verified that the error persists with v6.4.0-rc4 + Kuogee's patch (just in case you may have tested on sc7280 with 6.4). > > https://patchwork.freedesktop.org/patch/538601/?series=118148&rev=3 > > Apologies if you were not CCed on this, if a next version is CCed, > > will ask kuogee to cc you. > > Meanwhile, will be great if you can verify if it works for you and > > provide Tested-by tags. I see Bjorn also tested the patch. As it fixes a serious USB-C DP regression which broke USB-C DP completely on lazor for v6.3, can it be included in upcoming 6.3.y release? Thank you Leonard

As it fixes a serious USB-C DP regression which broke USB-C DP completely on lazor for v6.3, can it be included in upcoming 6.3.y release? Kuogee's fix has since been committed to drm-tip on 2023-06-08 as a8e981ac2d0eb9dd53a4c173e29ca0c99c88abe2. Since it fixes a serious regression in 6.3 and 6.4 kernels, can we include it for the stable releases? Thank you Leonard
