Hi, I did not integrate all my patches for state handling like I had before but just two patches which seems interresting to me: - The first one allows the device ti be used only when a guest is currently using it. Otherwise the device is in NOT_OPER state - The second rework the sch_event callback: AFAIU we can not consider that the event moves the device in IDLE state. I think we better let it as it is currently.
