If PCIE1 is left with the default (zero) AXI QoS values, endpoints can receive extremely poor service for non-posted transactions e.g. reads. Such transactions can take milliseconds to complete on a contended system. Bump priorities for every TC above the non-realtime greedy peripherals in BCM2712, to allow reasonable service without competing against hard realtime peripherals.
