Output Explanation

SGX Features

  • SGX2: whether dynamic addition of regular enclave pages to an enclave is supported.
  • EXINFO: whether EXtended INFOrmation is provided such as exception information on GP (General Protection Fault) or PF (Page Fault) that occurred inside an enclave.
  • ENCLV: whether managing enclaves in a virtualized environment is supported.
  • OVERSUB: whether memory oversubscription is supported.
  • KSS: whether the Key Separation and Sharing feature are supported.
  • Total EPC size: the amount of Enclave Page Cache available for enclaves.

Flexible Launch Control

If Flexible Launch Control is enabled, then launching an enclave that was not signed by Intel is allowed.

SGX System Software

  • SGX kernel device: whether a suitable SGX kernel device was detected.
  • libsgx_enclave_common: whether the libsgx enclave common library is available.
  • AESM service: whether the Application Enclave Services Manager is running.
