It looks like xen does not save the context for GICV. Since it is used by multiple VMs for acting as a GICC, should xen save and restore the status of GICV? ^ permalink raw reply [flat|nested] 2+ messages in thread

This is not necessary, since the GICV is driven by the settings given the GICH which we do context switch as necessary. The GICV is just the guest's window onto that state.
