I need to control exactly which ring each batchbuffer is submitted to if there is more than 1 BSD ring as I need to fill the queues in a known manner. My understanding is that if I submit to BSD when there is BSD1 and BSD2 the kernel will choose which ring it gets submitted to.
If this logic breaks other tests I will remove this patch and put the logic in the scheduler test.

The code does what exactly what we want. We run BSD or BSD, BSD1, BSD2 (because in this case we have no idea what BSD actually is).
