The system includes a machine-independent PCI bus subsystem
and several
machine-independent PCI device drivers.
Your system may support additional PCI devices. Drivers for
PCI devices
not listed here are machine-dependent. Consult your system's intro(4)
for additional information.
Details specific to the i386 [Toc] [Back]
Note that interrupt mappings on the i386 may require that
you configure
your BIOS to reserve sufficient interrupts as "PCI/ISAPnP"
so that there
are sufficient interrupts remaining to configure the discovered PCI devices.
For more information, see pcibios(4).

If the kernel is compiled with the USER_PCICONF kernel option, the following
ioctl(2) calls are supported by the pci driver. They
are defined
in the header file <sys/pciio.h>.
PCIOCREAD This ioctl(2) reads the PCI configuration
registers
specified by the passed-in pci_io structure. The pci_io
structure consists of the following fields:
pi_sel A pcisel structure which specifies the bus,
slot and function the user would
like to
query.
pi_reg The PCI configuration register
the user would
like to access.
pi_width The width, in bytes, of the data
the user
would like to read. This value
can be only 4.
pi_data The data returned by the kernel.
PCIOCWRITE This ioctl(2) allows users to write to the
PCI specified
in the passed-in pci_io structure. The
pci_io structure
is described above. The limitations on data width described
for reading registers, above, also
apply to
writing PCI configuration registers.
/dev/pci Character device for the pci driver.

The machine-independent PCI subsystem appeared in OpenBSD
2.0. Support
for device listing and matching was re-implemented by Kenneth Merry, and
first appeared in FreeBSD 3.0.
