This should definitely be 'gem_ctx_rpcs' :)

Unless I missed it, this test only checks that the registers are
written to and get read. It doesn't functionally validate that the
hardware actually performs differently based on what you set? 

Maybe under benchmarks/ it would be appropriate to compare the effect
on processing power, and make sure performance improves with additional
slices (except when it doesn't :P)
