  "message": "KVM: arm64: iommu: smmu: VM teardown for stage-1\n\nWhen a VM is teardown, it may still have pages in mapped in it\u0027s\nIOMMU, these pages are refcounted and never reclaimed.\n\nTo cleanly teardown IOMMUs from VMs, 2 operations are needed:\n- Clear STE/CDs to have invalid configs implemented by\n  kvm_iommu_force_detach_dev\n- Free all page tables used and decrement the refcount for page\n  mapped, Implemented in kvm_iommu_free_guest_domains, to avoid\n  walking all domain space, we add nr_domains for hyp_vm so we exit\n  early once all domains are freed. Another apporach that requires\n  dynamic allocation is to have a list of domains belong to the\n  hyp_vm.\n\nOne difference between teardown and other IOMMU operations, is that\nthe hyp_vcpu is not loaded, so pkvm_get_loaded_hyp_vcpu() can\u0027t be\nused in reclaim path.\nA new per-cpu variable is added to mark the context of teardown\noperation.\n\nSigned-off-by: Mostafa Saleh \u003csmostafa@google.com\u003e\n",
