Hi, I have "WARN_ON(!drm_modeset_is_locked(&crtc->mutex))" in tilcdc crtc enable and disable callbacks. Now those warnings are firing when resuming from suspend and I see that "drm_modeset_lock_all(dev)" has been removed from "drm_atomic_helper_resume()". I guess I should remove those warnings from tilcdc since no other driver has such warnings in place, but it still seems odd to me that the crtc enable or disable maybe called without the crtc modeset lock. Is there something wrong with drm_atomic_helper_resume() locking or am just confused about how the locking in drm works? (The later is probably true in any case) Best regards, Jyri _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
