KVM: arm64: vgic-its: KVM_DEV_ARM_ITS_SAVE/RESTORE_TABLES
Introduce new attributes in KVM_DEV_ARM_VGIC_GRP_CTRL group: - KVM_DEV_ARM_ITS_SAVE_TABLES: saves the ITS tables into guest RAM - KVM_DEV_ARM_ITS_RESTORE_TABLES: restores them into VGIC internal structures. We hold the vcpus lock during the save and restore to make sure no vcpu is running. At this stage the functionality is not yet implemented. Only the skeleton is put in place. Signed-off-by: Eric Auger <eric.auger@redhat.com> [Given we will move the iodev register until setting the base addr] Reviewed-by: Christoffer Dall <cdall@linaro.org>
