Detailed Description

This structure defines the common base interface used to enumerate and interact with all device drivers. It should be embedded inside a more specific 'per-bus' struct, and interacted with through the bus's API.

Example:

struct pci_driver {
    struct device_driver driver;
    void *pci_specific_field_1;
    int pci_specific_field_2;
};
 
void pci_driver_register(struct pci_driver *driver)
{
    // Perform pci-specific actions
    // ...
 
    // Register driver generically
    driver_register(&driver->driver);
}

To interact with a pci_device, we will interact with the pci_* functions. These functions will be the one to interact with the driver_* api instead, adding into the process the steps/configuration necessary for PCI devices to work.

The documentation for this struct was generated from the following file:
