This flags cause cmdstream to be executed from the ringbuffer (RB) instead of IB1. Normally not something you'd ever want to do, but it is super useful for firmware debugging. Hidden behind CAP_SYS_RAWIO and a default=n kconfig option which depends on EXPERT (and has a suitably scary warning), to prevent it from being used on accident.

Only use this if you are a driver developer. This should *not*

be enabled for production kernels. If unsure, say N.
