There are probably those more knowledgeable about PCI than I, but I
will offer my opinion.? I don’t think this type of scheme will meet
PCI 2.x specs, just because of the reasons you stated.? All PCI
devices must respond to the configuration address space at all times.
Correct.
We deal with a similar situation by using a PLX9080 to provide the
PCI interface. This handles the configuration space so that we can
do neato things like let the driver reload the FPGA at will. The
FPGA does *not* implement anything PCI, that is up to the PLX chip.
Which by the way is a “bridge” chip (PCI to i960 bus) but not a PCI-to-PCI
bridge.
