pcie_device

Description

This interface must be implemented by all PCIe devices that can receive downstream transactions.

connected and disconnected are used to indicate that the device is (dis)connected to port_obj with device id device_id and may use the pcie_map interface to add/remove functions and claim/release other resources. These functions should only be called once for each (dis)connected physical device no matter how many physical or virtual functions it has. The device_id contains the device number (D part of B:D:F) and should use 0 as the function number (F part of B:D:F).

hot_reset is used to indicate that a Hot Reset has been signaled on the PCIe link to which the device is connected. It is up to the device to reset functions and other resources mapped using the pcie_map interface.

Note: This interface is considered tech-preview and may change without notice.
