The basic SGX patches were merged into Qemu release, the left NUMA function for SGX should be enabled. The patch1 implemented the SGX NUMA ACPI to enable NUMA in the SGX guest. Since Libvirt need detailed host SGX EPC sections info to decide how to allocate EPC sections for SGX NUMA guest, the SGXEPCSection list is introduced to show detailed sections info in the monitor or HMP interface.
