pcie_function_info

Description

This interface should be implemented by all PCIe functions that wants to provide useful information for inspecting the function.

get_device_id returns the device id of the function.

get_upstream_target returns the upstream target of the PCIe device the PCIe function belongs to.

is_virtual_function returns true if the function is a virtual function.

get_bar_map_obj returns the object that is mapped by the BAR at bar_offset. If there is no BAR register at bar_offset, NULL is returned. For a physical function, the bar_offset is the offset in the Type 0/1 Configuration Space Header. For a virtual function, the bar_offset is the offset in the SR-IOV Extended Capability structure of the associated physical function (starting at 0x24).
