[PATCH v14 09/15] Convert QMP capabilities to domain capabilities

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Haibin Huang <haibin.huang@xxxxxxxxx>

the QMP capabilities:
  {"return":
    {
      "sgx": true,
      "section-size": 1024,
      "flc": true
    }
  }

the domain capabilities:
  <sgx>
    <flc>yes</flc>
    <epc_size>1</epc_size>
  </sgx>
