Does the LogiCORE PCI interface support a multifunction capability?
A multifunction device is a single piece of silicon that incorporates between two and eight 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 or not a device has multifunction capability. The Xilinx LogiCORE PCI interface does not support multifunction capability and has this read-only bit set to zero.
