I am looking at this code:
$ git grep tcg_ softmmu/physmem.c
softmmu/physmem.c:153:static void
tcg_log_global_after_sync(MemoryListener *listener);
softmmu/physmem.c:154:static void tcg_commit(MemoryListener *listener);
softmmu/physmem.c:161: * @tcg_as_listener: listener for tracking changes

softmmu/physmem.c:167: MemoryListener tcg_as_listener;

softmmu/physmem.c:654:void tcg_iommu_free_notifier_list(CPUState *cpu)
softmmu/physmem.c:668:void tcg_iommu_init_notifier_list(CPUState *cpu)
softmmu/physmem.c:698: tcg_register_iommu_notifier(cpu, iommu_mr,
iommu_idx);
softmmu/physmem.c:761: if (tcg_enabled()) {
softmmu/physmem.c:762:
newas->tcg_as_listener.log_global_after_sync = tcg_log_global_after_sync;
softmmu/physmem.c:763: newas->tcg_as_listener.commit = tcg_commit;
softmmu/physmem.c:764:
memory_listener_register(&newas->tcg_as_listener, as);
softmmu/physmem.c:891: assert(tcg_enabled());
softmmu/physmem.c:904: if (cc->tcg_ops->adjust_watchpoint_address) {

softmmu/physmem.c:2700: assert(tcg_enabled());
softmmu/physmem.c:3000: if (tcg_enabled()) {
which reminded me the starter generic part of your effort
(already merged).
Do you have plans for this code?
Similarly:
$ git grep kvm_ softmmu/physmem.c
softmmu/physmem.c:752: assert(asidx == 0 || !kvm_enabled());
softmmu/physmem.c:1295: if (kvm_enabled())
softmmu/physmem.c:1296: kvm_flush_coalesced_mmio_buffer();
softmmu/physmem.c:1566: if (kvm_enabled()) {
softmmu/physmem.c:2046: if (kvm_enabled() && !kvm_has_sync_mmu()) {
Thanks,
Phil.
