Hardware Report: Amazon C5 instances (c5.large) #37
Description
Amazon announced on 11/30/2016 the addition of Amazon EC2 C5 instances in early 2017 powered by Intel Xeon Skylake that comes with SGX capabilities. Here's the report from a c5.large running Ubuntu 16.04:

Because of the fact that is cloud infrastructure, getting access to tweak the BIOS seems highly unlikely. I tried installing the linux-sgx-driver, which did install but remains unused, and installed linux-sgx SDK & PSW, and the SampleEnclave code returns Intel SGX is not supported by this processor., which I believe is not technically true (instead of saying that SGX needs to get enabled through the BIOS).
Any ideas for things I could try or investigate further?
Thanks for the awesome work on this repo, BTW. Much appreciated!
