LogiCORE PCI: Does the PCI Interface support multi-function (multifunction) capability?


Problem Description:
General Description:

Does the LogiCORE PCI interface support a multi-function capability?


Solution 1:

A multi-function device is a single piece of silicon that incorporates
between 2 and 8 functions. The multiple functions within a device share
the device's PCI interface.

The BIT 7 in the Header Type register in the PCI configuration space is
used to determine whether a device is multi-function or not. The Xilinx
LogiCORE PCI interface does not support multi-function capability at
this time and has this Read Only bit set to zero.
