No idea. All hw interaction should be covered by selftests (this
certainly is), the raison d'etre for igt is to cover user observable
behaviour. For the simulator, we should just be able to use seftests
followed by bare uABI checks before moving onto real workloads.

Nope, that is nothing to do with me. Someone else thought is was a good
idea. I do not like having tests vary, make different tests.
