Unfortunately not.
Maybe add a readback of the VM base addr pointer to make sure that the
write has really reached the SBRM?
Otherwise I'm out of ideas as well,

AFAICT cik_hdp_flush_cp_ring_emit() always uses the PFP though.
Note also that the engine bit is not always consistent (for some packets 0
= ME, 1 = PFP and for others 1= ME and 0 = PFP).
Ugh. Then we should probably use explicit *_ENGINE_PFP/ME macros instead
of *_ENGINE(lucky_number). :)
