Hi Stefano, On 04/05/2017 09:28 PM, Stefano Stabellini wrote: When an irq migration is already in progress, but not yet completed (GIC_IRQ_GUEST_MIGRATING is set), refuse any other irq migration requests for the same irq. This patch implements this approach by returning success or failure from vgic_migrate_irq, and avoiding irq target changes on failure. It prints a warning in case the irq migration fails. It also moves the clear_bit of GIC_IRQ_GUEST_MIGRATING to after the physical irq affinity has been changed so that all operations regarding irq migration are completed.
