IN static device_method_t pci_methods[] =3D {
what is the freeBSD's magic to connect pci_read_config_method wtih
PCI_READ_CONFIG? awk script?and so on?
which
DEVMETHOD(pci_read_config,=09pci_read_config_method), in pci.c
command =3D PCI_READ_CONFIG(dev, child, PCIR_COMMAND, 2); in
pci_enable_io_method in pci.c
and what if i create a new method in pci method interface ?
such as DEVMETHOD(pci_have_rest ,=09pci_have_rest_method)
what else should i do when i want to use PCI_HAVE_REST(dev ) point to
pci_have_rest_method
