DESCRIPTION

     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

     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 dev-
     ices. For more information, see pcibios(4).

IOCTLS

     If the kernel is compiled with the USER_PCICONF kernel option, the fol-
     lowing 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.

FILES

     /dev/pci  Character device for the pci driver.

HISTORY

     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.
