Set Size of SGX Enclave

g5 Notebook
Linux

Hi All,

I have a question about using the Intel SGX (Software Guard Extensions). I have a dual boot HP g5 Notebook with Ubuntu 18.04 and Windows 10. I have built the SDK and linux driver for using SGX and successfully run the sample programs provided. In the BIOS I had to set the SGX to "Enabled". There are three options: "Disabled", "Enabled" , and "Software Controlled". My research tells me that there is often another option to control the size of the SGX Enclave. Often three options are provide: 128 MB, 64 MB, and 32 MB. I do not have these options in my BIOS. Has HP not provided this option for my machine? Is there anyway to modify the size of the SGX Enclave that I am missing?

The Bios vendor is Insyde. I have updated to the latest recommended version, F.48, in hopes that this would give me more options but with no luck.

Any help would be appreciated,

-Will
