...ut I'm struggling to understand where malidp makes any specific mistakes. First of all, malidp is only a display engine, so there is no GPU attached to it, but that is only a small clarification. Second, malidp doesn't use directly any of the callbacks that you are referring to, it uses the drm_cma_xxxx() API plus the generic drm_xxxx() call. So if there are any issues there (as they might well be) I think they would apply to a lot more drivers and the fix will involve more than just malidp, i915 and msm. Would love to get any clarifications on what I might have misunderstood. Best regards, Livi...

Fix a deadlock on hybrid graphics laptops that's been present since 2013: DRM drivers poll connectors in 10 sec intervals. The poll worker is stopped on ->runtime_suspend with cancel_delayed_work_sync(). However the poll worker invokes the DRM drivers' ->detect callbacks, which call pm_runtime_get_sync(). If the poll worker starts after runtime suspend has begun,
