Difference between pice driver and pcie port driver
There is a certain relationship between the PCIe port service driver and the PCIe driver, but they are different concepts.
PCIe drivers are drivers for managing and operating PCIe devices. It is responsible for communicating with the hardware and implementing configuration, data transmission and other related operations on PCIe devices. PCIe drivers usually involve device initialization, interrupt handling, addressing, DMA control, etc.
The PCIe port service driver is a special type of driver, which is specially used to manage and operate specific functions and operations of the PCIe port. A PCIe port is an interface used to connect a PCIe device on a host system, such as a slot or an interface integrated into a motherboard.
The PCIe port service driver provides the ability to control and manage PCIe ports by registering with the system. It can handle events related to PCIe ports, such as hot plug events, power management, error handling, etc. The port service driver can interact with the PCIe driver through callback functions, etc., so as to realize cooperative operation and function expansion of the PCIe port.
Therefore, the PCIe driver is a driver program used to manage and operate PCIe devices, and the PCIe port service driver is a driver program specially used to manage and operate PCIe ports. They cooperate with each other to realize the control and management of PCIe devices and ports.
