Hi All,
In the context of a school project on computers architecture, I have to make a PCI Bus Enumerator.
The code will be divided into two layers :
- An enumeration layer that handle enumeration of the differents buses and devices in each bus. It then must use a data structure to store all these informations (Tree maybe?) and other informations about the device (vendor id, device id, functions). It should generate a tree representing all the devices and buses.
This layer will then be ported to the kernel land (fictive of course).
- A display layer that take the data structure and display it (using dashes, colors, spaces etc... It must be fashion).
To make this program, I can use assembly languages or C language. I can't use any API. I must talk directly to the hardware and/or use BIOS routines.
I have to deliver a binary that runs on Linux or Win32.
Having only assembly concepts (Hello world :/), I don't see at all how can I start this project. I read some articles on OsDev and I more or less understood the operation (use two loops to browse the buses and devices and check for every device/bus if it exists and if it have functions). But I don't know how to code this.
It's why I ask for your help. Naturally, I don't want any pre-made code, I'm very motivated to learn.
Thanks.
(Sorry for my english, I'm french).
