Dmitry promised > to take a look one day. Thanks. For the record, I had already withdrawn this patch after the sashiko-bot review (the self refresh exit path, and the vblank worker touching DPU registers after the last runtime PM reference is gone). It was never meant to make self refresh work, only to avoid the atomic helper warning about vblank being disabled on a self refresh "disable". I have no fix for the black screen, but I am happy to test whatever Dmitry comes up with on the Surface Pro 11 (x1e80100, OLED eDP panel). Ramón
