Our system is designed around a T1040 series SoC and it will be running hypervisor with 2 to 4 partitions each running a version of linux. The design calls for accepting a data load request from any of the partitions (cpu's running linux). when the request is received the system needs to shut down gracefully and return to single cpu to data load the system. How can I shutdown gracefully without something like letting the WDT timeout and resetting the system? Is there another way to do this? Will one partition need to be in control and accept the request or can any partition accept the load request?
