Where can I find that info in > the manual? The DCP index helps describe the topology of the devices connected to the B/QMan. One might be tempted to use some address to reference said DCP, unfortunately the pertinent registers/bits for said DCP(s) are not into a compact region. Look at the CCSR memory map for B/QMan In the QMan case things are marginally better. For each hardware portal there are a handful of (vaguely named *DCx*, *DCPx* or *DCP*) registers (configuration, performance monitoring and debugging). However, still registers and bits spread here and there In the BMan case things are a bit worse as the registers names are less friendly and still spread around Do you need specific names/offsets?
