It relies on not upstreamed kernel series [1]. ITS tables are flushed into guest RAM on VM stop while registers are save on pre_save() callback. Tables and registers are restored on ITS post_load(). Redistributor pending tables also are flushed on VM stop, independently on ITS tables. That work was tested on Cavium ThunderX using virsh save/restore and virt-manager live migration. Best Regards Eric Host Kernel dependencies: - [1] [PATCH v5 00/22] vITS save/restore History: v4 -> v5: - adapt to the new user API - new patch "hw/intc/arm_gicv3_kvm: Implement pending table save" as the pending table save now is handled on GICV3 side. v3 -> v4: - oversight in v3, missed a last minute correction related to reg useless declaration in kvm_arm_its_pre_save v2 -> v3: - GITS_IIDR is now saved and restored to check ABI revision. - get/put functions renamed into pre_save/post_load - unmigratable = false removed - changed the migration blocker message - remove the extract64 round s->ctlr - reword some comments v1 -> v2: - rebase on 2.9 soft release code - handle case where migrate_add_blocker fails - add comments along with ITS and GICv3 migration priorities Eric Auger (4): linux-headers: Update for vITS save/restore hw/intc/arm_gicv3_its: Implement state save/restore hw/intc/arm_gicv3_kvm: Implement pending table save hw/intc/arm_gicv3_its: Allow save/restore hw/intc/arm_gicv3_common.c | 1 + hw/intc/arm_gicv3_its_common.c | 11 ++- hw/intc/arm_gicv3_its_kvm.c | 120 +++++++++++++++++++++++++++++---- hw/intc/arm_gicv3_kvm.c | 25 +++++++ include/hw/intc/arm_gicv3_its_common.h | 8 +++ include/migration/vmstate.h | 2 + linux-headers/asm-arm/kvm.h | 6 +- linux-headers/asm-arm64/kvm.h | 6 +- 8 files changed, 164 insertions(+), 15 deletions(-) -- 2.5.5
