PCI Device Polling Algorithm?

Question

Programming

Good day!
There is a Spartan 3 FPGA connected to the PCI bus. The connection diagram is available. It is necessary to write firmware for the FPGA so that when polling PCI devices, the OS would find the FPGA and require a driver for it (i.e., only configuration transactions are needed).
Where can I find the algorithm for polling PCI devices? It is desirable with an indication of which output of which level the signal should be, its level, duration.

Answer 1

Complete PCI bus specification

Answer 2

PCI bus specification

Answer 3

Yes, your title is spelled incorrectly :-) Many people think that we are talking about the PIC family - Microchip controllers.
