Yep, I was replying to the above comment about "community providing
patches to the SGX library" from Adam. Or maybe I misunderstood what he
said.

Is something ever as broken as it needs to be? =)

I'm not quite sure I understand what you're trying here. You said that
you want this work based on the latest SGX kernel driver from TI. That
driver is for the latest userspace libraries. I don't think it will ever
work with the old libraries.
