No, the pci server and the device driver should take care of this.

That means the driver has not explecitely to enable bus mastering for
its PCI device? (It is neccessary with Linux → pci_set_master …)

It is the responsibility of the driver to make sure that the bus master
enable bit is set in the command register of its device.
