Pci Express Root Complex Driver Dell
Hi everyone,
I try to understand PCI express since hours. Can anyone help me understand some points.
- Do i have to use root complex? In which cases it is fine not to use root complex?
- There is a CPU, root complex, switch and endpoints. if one of the end point wants to communicate with other endpoint, it goes to root complex and root complex forward the message. What is the role of CPU in this process?
- What is exactly a root complex? is it a device to be programmed in C or it does everything by recpect to datas, sent to it? (Same question also for switch)
Thanks a lot
Best regards
