KVM_SET_IRQCHIP is the state load ioctl, right (companion to KVM_GET_IRQCHIP)? It seems like a bit of an abuse to use that for configuration rather than for migration/sync of state with userspace... (For ARM we will just use the ONE_REG ABI for irqchip state save/load anyway, so KVM_SET_IRQCHIP isn't relevant.) -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
