NAME
     pci -- introduction to machine-independent PCI bus support and drivers

SYNOPSIS
     pci* at mainbus? bus ?
     pci* at pchb? bus ?
     pci* at ppb? bus ?

     options PCIVERBOSE
     options PCI_CONFIG_DUMP
     options PCI_ADDR_FIXUP
     options PCI_BUS_FIXUP
     options PCI_INTR_FIXUP

DESCRIPTION
     Other pci attachments are machine-dependent and depend on the bus topology and PCI bus
     interface of your system.	See intro(4) for your system for details.

     NetBSD 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.

OPTIONS
	PCI_ADDR_FIXUP	Fixup PCI I/O and memory addresses.

			Some i386 and amd64 BIOS implementations don't allocate I/O space and
			memory space for some PCI devices -- primarily BIOS in PnP mode, or lap-
			tops that expect devices to be configured via ACPI.  Since necessary
			space isn't allocated, those devices will not work without special han-
			dling.

			This option allocates I/O space and memory space instead of relying upon
			the BIOS to do so.

			If necessary space is already correctly assigned to the devices, this
			option leaves the space as is.

	PCI_BUS_FIXUP	Fixup PCI bus numbering; needed for many cardbus(4) bridges.

			Each PCI bus and CardBus should have a unique bus number.  But some BIOS
			implementations don't assign a bus number for subordinate PCI buses.  And
			many BIOS implementations don't assign a bus number for CardBuses.

			A typical symptom of this is the following boot message:
			      cardbus0 at cardslot0: bus 0 device 0...
			Please note that this cardbus0 has a bus number '0', but normally the bus
			number 0 is used by the machine's primary PCI bus.  Thus, this bus number
			for cardbus is incorrect (not assigned).  In this situation, a device
			located in cardbus0 doesn't show correct device ID, because its bus num-
			ber 0 incorrectly refers to the primary PCI bus, and a device ID in the
			primary PCI bus is shown in the boot message instead of the device's ID
			in the cardbus0.

			This option assigns bus numbers for all subordinate PCI buses and Card-
			Buses.

			Since this option renumbers all PCI buses and CardBuses, all bus numbers
			of subordinate buses become different when this option is enabled.

	PCI_INTR_FIXUP	Fixup PCI interrupt routing via PCIBIOS or ACPI.

			Some i386 and amd64 BIOS implementations don't assign an interrupt for
			some devices.

			This option assigns an interrupt for such devices instead of relying upon
			the BIOS to do so.

			If a valid interrupt has already been assigned to a device, this option
			leaves the interrupt as is.
