There is no fixed configuration for VMs. Is the intention to pass a DTS to the toolstack for it to create the VM with the appropriate amount of memory and peripheral mapped to the right place etc? Or is the toolstack going to create the VM and generate the DTB from (e.g.,) an xl VM configuration file. > + > + hypervisor { > + compatible = "xen,xen-4.2", "xen,xen"; > + reg = <0xb0000000 0x20000>; > + interrupts = <1 15 0xf08>; > + }; This node needs to be generated by the toolstack as only it knows what ABI the hypervisor has.
