![]() If we fail during GEM initialisation, we scrub the HW state by performing a device level GPU resuet. However, we want to leave the system in a usable state (with functioning KMS but no GEM) so after scrubbing the HW state, we need to restore some sane defaults and re-enable the low-level common parts of the GPU (such as the GMCH). v2: Restore GTT entries.
