[PATCH v8 5/5] misc: pci_endpoint_test: Document a policy about adding pci_device_id

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


To avoid becoming struct pci_device_id pci_endpoint_test_tbl longer
and longer, document a policy. For example, if PCIe endpoint controller
can configure vendor id and/or product id, you can reuse one of
existing entries to test.
