What is a KO file?
What is a KO file? File with a . KO extension contains source code of a module which expands the functionality of a Linux system kernel. These files, since the 2.6 version have substituted the . O files, due to the fact that they have additional information useful during loading modules through a kernel.

How do I create a Linux kernel driver?
To build a driver, these are the steps to follow:
- Program the driver source files, giving special attention to the kernel interface.
- Integrate the driver into the kernel, including in the kernel source calls to the driver functions.
- Configure and compile the new kernel.
- Test the driver, writing a user program.

What is a .KO file in Linux?
KO file is a Linux 2.6 Kernel Object. … A loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system. A module typically adds functionality to the base kernel for things like devices, file systems, and system calls.

How do drivers work in Linux?
Linux drivers are built with the kernel, compiled in or as a module. Alternatively, drivers can be built against the kernel headers in a source tree. You can see a list of currently installed kernel modules by typing lsmod and, if installed, take a look at most devices connected through the bus by using lspci .
How do I write network driver in Linux?
The open method should register any system resources it needs (I/O ports, IRQ, DMA, etc.), turn on the hardware and increment module usage count. stop – This is a pointer to a function that stops the interface. This function is called whenever ifconfig deactivates the device (for example, “ifconfig eth0 down”).
