From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Now that the GGTT PTE updates go straight to GSMBASE (bypassing GTTMMADR) there should be no more risk of system hangs? So the "binder" (ie. update the PTEs via MI_UPDATE_GTT) is no longer necessary, disable it. TODO: MI_UPDATE_GTT might be interesting as an optimization though, so perhaps someone should look into always using it (assuming the GPU is alive and well)?
