numa: Support SGX numa in the monitor and Libvirt interfaces
Add the SGXEPCSection list into SGXInfo to show the multiple SGX EPC sections detailed info, not the total size like before. This patch can enable numa support for 'info sgx' command and QMP interfaces. The new interfaces show each EPC section info in one numa node. Libvirt can use QMP interface to get the detailed host SGX EPC capabilities to decide how to allocate host EPC sections to guest. (qemu) info sgx SGX support: enabled SGX1 support: enabled SGX2 support: enabled FLC support: enabled NUMA node #0: size=67108864 NUMA node #1: size=29360128 The QMP interface show: (QEMU) query-sgx {"return": {"sgx": true, "sgx2": true, "sgx1": true, "sections": \ [{"node": 0, "size": 67108864}, {"node": 1, "size": 29360128}], "flc": true}} (QEMU) query-sgx-capabilities {"return": {"sgx": true, "sgx2": true, "sgx1": true, "sections": \ [{"node": 0, "size": 17070817280}, {"node": 1, "size": 17079205888}], "flc": true}} Signed-off-by: Yang Zhong <yang.zhong@intel.com> Message-Id: <20211101162009.62161-4-yang.zhong@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
