Re-initing the VCPU is actually the right way to do this -- it is feeding all the register state back to KVM that is the hack. (One day I may fix 32 bit ARM to re-init the VCPU). Why does this only work for mach-virt? thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
