Arria 10 GX pcie and xaui transceiver interaction

I see this is an old thread - but for what it's worth I just had to deal with same issue (PCIe + DisplayPort). The PCIe hard IP instances (if used) take precedence and actually gate/prevent calibration of any GXBs downstream from them, if the PCIe HIP modules don't calibrate properly (i.e. aren't connected). The cal_busy / cal_done signals are buried in the fabric and can't be manipulated, as far as I can tell. Was looking into faking the calibration complete to bypass situations where PCIe not connected but want to use the rest of the system. Haven't figured out how to do that yet.

See info on page 582 (Sec 7.3 - Power-up Calibration) :
