Since there is no fill_device_info() callback support, and when we execute "info memory-devices" command in the monitor, the segfault will be found. This patch will add this callback support and "info memory-devices" will show sgx epc memory exposed to guest. The result as below: qemu) info memory-devices Memory device [sgx-epc]: "epc1" memaddr: 0x180000000 size: 29360128 memdev: /objects/mem1 Memory device [sgx-epc]: "epc2" memaddr: 0x181c00000 size: 10485760 memdev: /objects/mem2 Signed-off-by: Yang Zhong <yang.zhong@intel.com> v1-->v2: - "Since: 5.1" to "Since: 6.1"(Eric Blake). --- hw/i386/sgx-epc.c | 17 ++++++++++++++++- monitor/hmp-cmds.c | 10 ++++++++++ qapi/machine.json | 26 +++++++++++++++++++++++++- 3 files changed, 51 insertions(+), 2 deletions(-)
