Runtime PCIe card(device) detection Support by linux kernel

Dear All,

We're working on i-wave RZ/G1n evaluation board. it has PCIe port on its carrier board. linux kernel 3.10.31 source code is built and uImage is flashed onto the board.

Please let us know how it scans the PCIe device during run-time. where can i find the code responsible for device detection during run-time in the source code, and by

what mechanism it detects the device(polling or interrupt).

Thanks,
