Chapter 30. The eCos PCI Library
Note: The chunk of PCI memory space directly addressable though the window by the CPU may be smaller
than the amount of PCI memory actually provided. In that case drivers will have to access PCI memory space
in segments. Doing this will be platform specific and is currently beyond the scope of the HAL.
HAL_PCI_IGNORE_DEVICE( bus, dev, fn )
This macro, if defined, may be used to limit the devices which are found by the bus scanning functions. This is
sometimes necessary for devices which need special handling. If this macro evaluates to
true , the given device
will not be found by cyg_pci_find_next or other bus scanning functions.
