The intel_sgx dir should have also a .gitignore to exclude the other LE related output files: drivers/platform/x86/intel_sgx/le/enclave/sgx_le.ss drivers/platform/x86/intel_sgx/le/enclave/sgxsign drivers/platform/x86/intel_sgx/le/sgx_le_proxy > If the default key does not exist kbuild will generate a random key and > place it to this location.
