+Another use case is for the PCI device to be split out into +multiple sub functions. For each sub function an auxiliary_device +will be created. A PCI sub function driver will bind to such +devices that will create its own one or more class devices. A PCI +sub function auxiliary device will likely be contained in a struct +with additional attributes such as user defined sub function number +and optional attributes such as resources and a link to
the
+parent device. These attributes could be used by systemd/udev; and
hence should
+be initialized before a driver binds to an auxiliary_device.
This does not read like an explicit example like the previous 2. Did you have something specific in mind?
This was added by request of Parav.
This example describes the mlx5 PCI subfunction use case. I didn't follow your question about 'explicit example'. What part is missing to identify it as explicit example?
