Intel: With Stratix IV GX's PCI-Express hard IP, is it possible to access the PCI configuration space from the application layer side? For example, things like vendor ID and base address need to be changed dynamically at device startup.

Intel: Will the Stratix IV GX's PCI-Express hard IP allow access to the PCI configuration space from the application layer side? For example, the vendor ID, base address, etc. should change dynamically when the device boots.

PCI Express

The PCI configuration space must be changed dynamically according to the user's usage, such as when using the PCI-Express hard IP in a Stratix IV GX device and then migrating to a HardCopy IV GX device.
In preparation for such cases, a function is implemented that allows access to the PCI configuration space from the FPGA fabric side.

The PCI configuration space can be accessed using the Local Management I/F (LMI).
