We create optional sections with this patch. But we already have optional subsections. Instead of having two mechanism that do the same, we can just generalize it. For subsections we just change: - Add a needed function to VMStateDescription - Remove VMStateSubsection (after removal of the needed function it is just a VMStateDescription) - Adjust the whole tree, moving the needed function to the corresponding VMStateDescription Signed-off-by: NJuan Quintela <quintela@redhat.com>

commit 46c804de ("s390x: move fpu regs into a subsection of the vmstate") moved the fprs into a subsection and bumped the version number. This will allow to not transfer fprs in the future if necessary. Add a comment to mark the return true as intentional.

When migrating a guest, be sure to include the vector registers. The vector registers are defined in a subsection, similar to the existing subsection for floating point registers. Since the floating point registers are always present (and thus migrated), we can skip them when performing the migration of the vector registers which may or may not be present.

Handle the actual syncing of the vector registers with kernel space, via the get/put register IOCTLs. The vector registers that were introduced with the z13 overlay the existing floating point registers. FP registers 0-15 are the high-halves of vector registers 0-15. Thus, remove the freg fields and replace them with the equivalent vector field to avoid errors in duplication. Moreover, synchronize either the vector registers via kvm_sync_regs, or floating point registers via the GET/SET FPU IOCTLs.

This patch adds support to migrate vcpu interrupts. We use ioctl KVM_S390_GET_IRQ_STATE and _SET_IRQ_STATE to get/set the complete interrupt state for a vcpu.

Let's move the floating point registers into a seperate subsection and bump up the version id. This cleans up the current vmstate and will allow for a future extension with vector registers in a compatible way. This patch is based on a patch from Eric Farman.

This patch adds handling code for the following SIGP orders: - SIGP SET ARCHITECTURE - SIGP SET PREFIX - SIGP STOP - SIGP STOP AND STORE STATUS - SIGP STORE STATUS AT ADDRESS SIGP STOP (AND STORE STATUS) are the only orders that can stay pending forever (and may only be interrupted by resets), so special care has to be taken about them. Their status also has to be tracked within QEMU. This patch takes care of migrating this status (e.g. if migration happens during a SIGP STOP). Due to the BQL, only one VCPU is currently able to execute SIGP handlers at a time. According to the PoP, BUSY should be returned if another SIGP order is currently being executed on a VCPU. This can only be implemented when the BQL does not protect all handlers. For now, all SIGP orders on all VCPUs will be serialized, which will be okay for the first shot.

CPU_SAVE_VERSION was undefined, so "cpu_common" VMState and cpu_{save,load}() were not registered. They were no-ops. Therefore there is no backwards compatibility to keep, so we can mark S390CPU as unmigratable at device level.
