'failed to load enclave' in hardware mode with Intel SGX

[alepvn33]

Hello everyone,

For the past few days, following the official guide (https://gramine.readthedocs.io/en/latest/devel/building.html) I've been trying to install Gramine in my laptop (HP EliteBook 840 G3, Intel Core i7-6500U CPU @ 2.50GHz × 4, Ubuntu 18.04.6 LTS, 5.4.0-150-generic) without any luck.

The point where I'm stuck is the Intel SGX installing. For the drivers, I upgrade my kernel to the 5.11.5 and the drivers are already included. Then, after building and installing Intel SGX SDK as the official Intel guide (https://download.01.org/intel-sgx/latest/dcap-latest/linux/docs/Intel_SGX_SW_Installation_Guide_for_Linux.pdf) says, I use the sample code under SampleCode/LocalAttestation in simulation mode to check the installing, and everything works perfectly. However, after building and installing PSW and running the sample code in hardware mode, I get "failed to load enclave" as a result. I tried everything but nothing seems to work. In the attached txt I show every command that I used to clarify my situation.

Can you please help me? I've tried everything so far.

Thanks!

Hi Alepvn33,

Thanks for reaching out.

The issue might be because your SGX driver is not loaded. Try running these commands and see if you get any errors. If an error arises, it means that the SGX driver was not correctly installed.

$ sudo /sbin/depmod

$ sudo /sbin/modprobe isgx

Regards,

Aznie
