txs contains the config space?It is not the config space, but a memory slave port.Then where is the config space? It should not be part of "ranges" is all I care about.The config space is not part of "ranges". Our IP uses TLP packet to access config space.It took me a bit to figure out what you mean here. To save others from reading the source, here is what I found: * The config space is accessed indirectly through registers from the "cra" register range, which is the right approach according to the point that Rob made. * hardware-wise this basically looks like bit-banged PCIe, which is both awesome and scary ;-)
drivers/pcie/host/pcie-host-gpio.c anyone? ;-) M. -- Jazz is not dead. It just smells funny.
