In LS1043A DPAA hardware, current work queue (WQ) scheduling follows two level scheduler schema, which is mixture of strict and round-robin prioritization.

 

DPAA work queue prioritization

 

Is somehow possible to simplify the DPAA approach and use only 8 strict priorities with round robin completely disabled? (WQ 0 -> Priority 0, WQ 1 -> Priority 1, WQ 2 -> Priority 2, ..., WQ 7 -> Priority 7. Higher priority WQ has absolute strict priority over all lower priority WQs)
