Failed to open Intel SGX device. #684

Open Ruk1ng001 opened 3 years ago

Ruk1ng001 commented 3 years ago

I use these files to run:

sgx_linux_x64_driver_1.41.bin 
sgx_linux_x64_sdk_2.13.100.4.bin

but when I run sgx_linux_x64_driver_1.41.bin, I get info as follow:

Unpacking Intel SGX Driver ... done.
Verifying the integrity of the install package ... done.

This is a error?

Finnally, I get error when I run ./app:

# ./app

Info: Please make sure SGX module is enabled in the BIOS, and install SGX driver afterwards.

Please check if the platform supports SGX/FLC.

Ruk1ng001 commented 3 years ago

Yes, I can successfully install this driver (sgx_linux_x64_driver_2.11.0_0373e2e.bin).But get error when I install sgx_linux_x64_driver_1.41.bin

xiangquanliu commented 3 years ago

Seems not all the driver installation messages are attached. Please check if the messages includes "You may need to run /sbin/modprobe intel_sgx (--allow-unsupported) or reboot system manually!"

Ruk1ng001 commented 3 years ago

Yes, I hava this message.

xiangquanliu commented 3 years ago

So please run /sbin/modprobe intel_sgx (--allow-unsupported) manually and check if it is successful. If not, please check if the platform supports SGX/FLC.

Ruk1ng001 commented 3 years ago

When I run this :

# /sbin/modprobe intel_sgx
modprobe: ERROR: could not insert 'intel_sgx': No such device

And how to check if it is supported?

xiangquanliu commented 3 years ago

From the above message, I think it is not supported.
