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, seepcibios(4).
OpenBSD provides support for the following devices. Note that not all architectures support all devices.

VirtIO support driver
IOCTLS
If the kernel is compiled with theUSER_PCICONF kernel option, the followingioctl(2) calls are supported by the pci driver. They are defined in the header file<sys/pciio.h>.
PCIOCREAD struct pci_io *
This ioctl(2) reads the PCI configuration registers specified by the passed-in pci_io structure. Thepci_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 struct pci_io *
This ioctl(2) allows users to write to the PCI device specified in the passed-in pci_io structure. Thepci_io structure is described above. The limitations on data width described for reading registers, above, also apply to writing PCI configuration registers.
PCIOCGETROM struct pci_rom *
This ioctl(2) allows users to read the contents of the PCI ROM specified in the passed-in pci_rom structure. Thepci_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.
