What is the use of Kconfig file in Linux?
KConfig is a selection-based configuration system originally developed for the Linux kernel. It is commonly used to select build-time options and to enable or disable features, and has now found use in other projects beyond the Linux kernel.
How to check what kernel options were compiled?

Although it is open-source – meaning anyone can view and modify the code – the Linux kernel is built with multiple protocols to ensure stability and security. This guide will walk you through how to check the Linux kernel version of your operating system.
How does the Linux kernel work with PCI drivers?
The kernel uses these values to match a driver to a device properly. PCI drivers tell the kernel which vendor and device IDs they will support so that the kernel knows how to bind the driver to the proper device. Write them down somewhere, as we will refer to them later.
