DESCRIPTION
The system includes a machine-independent PCI bus subsystem and several
machine-independent PCI device drivers.
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).
OpenBSD provides support for the following devices. Note that not all
architectures support all devices.

IOCTLS
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 device
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.
PCIOCGETROM This ioctl(2) allows users to read the contents of the
PCI ROM specified in the passed-in pci_rom structure.
The pci_rom structure consists of the following fields:
pr_sel A pcisel structure which specifies the bus,
slot and function the user would like to
query.
pr_romlen Size of the buffer to store the contents of
the ROM. Upon return, this field will
contain the size of the ROM
pr_rom The address of the buffer to store the
contents of the ROM.
If the ROM is larger than the specified buffer size,
ENOMEM will be returned.
FILES
/dev/pci* Character device for the pci driver.
