That looks wrong for MTL actually since dma address is relative to the start of LMEMBAR but stolen io.start will be LMEMBAR+8MiB (or just DSMBASE which points to the same place, with the w/a in place). So we need to subtract mem->region.start from this to get the correct value. -- Ville Syrjälä Intel
