introduction to machine-independent PCI bus support and drivers 38.Sh SYNOPSIS 39.Cd "pci* at mainbus? bus ?" 40.Cd "pci* at pchb? bus ?" 41.Cd "pci* at ppb? bus ?" 42.Pp 43.Cd options PCIVERBOSE 44.Cd options PCI_CONFIG_DUMP 45.Cd options PCI_ADDR_FIXUP 46.Cd options PCI_BUS_FIXUP 47.Cd options PCI_INTR_FIXUP 48.Sh DESCRIPTION 49Other 50.Nm 51attachments are machine-dependent and depend on the bus topology and 52.Tn PCI 53bus interface of your system. 54See 55.Xr intro 4 56for your system for details. 57.Pp 58.Nx 59includes a machine-independent 60.Tn PCI 61bus subsystem and 62several machine-independent 63.Tn PCI 64device drivers. 65.Pp 66Your system may support additional 67.Tn PCI 68devices. 69Drivers for 70.Tn PCI 71devices not listed here are machine-dependent. 72Consult your system's 73.Xr intro 4 74for additional information. 75.Sh OPTIONS 76.Bl -tag -width PCI_ADDR_FIXUP -offset 3n 77.It Dv PCI_ADDR_FIXUP 78Fixup PCI I/O and memory addresses. 79.Pp 80Some i386 and amd64 BIOS implementations don't allocate I/O space and 81memory space for some PCI devices -- primarily BIOS in PnP mode, or laptops 82that expect devices to be configured via ACPI. 83Since necessary space isn't allocated, those devices 84will not work without special handling. 85.Pp 86This option allocates I/O space and memory space 87instead of relying upon the BIOS to do so. 88.Pp 89If necessary space is already correctly assigned to the devices, 90this option leaves the space as is. 91.It Dv PCI_BUS_FIXUP 92Fixup PCI bus numbering; needed for many 93.Xr cardbus 4 94bridges. 95.Pp 96Each PCI bus and CardBus should have a unique bus number. 97But some BIOS implementations don't assign a bus number 98for subordinate PCI buses. 99And many BIOS implementations 100don't assign a bus number for CardBuses. 101.Pp 102A typical symptom of this is the following boot message: 103.D1 Sy cardbus0 at cardslot0: bus 0 device 0... 104Please note that this cardbus0 has a bus number 105.Sq 0 , 106but normally the bus number 0 is used by the machine's 107primary PCI bus. 108Thus, this bus number for cardbus is incorrect 109.Pq not assigned . 110In this situation, a device located in cardbus0 doesn't 111show correct device ID, 112because its bus number 0 incorrectly refers to the primary 113PCI bus, and a device ID in the primary PCI bus is shown 114in the boot message instead of the device's ID in the cardbus0. 115.Pp 116This option assigns bus numbers for all subordinate 117PCI buses and CardBuses. 118.Pp 119Since this option renumbers all PCI buses and CardBuses, 120all bus numbers of subordinate buses become different 121when this option is enabled. 122.It Dv PCI_INTR_FIXUP 123Fixup PCI interrupt routing via PCIBIOS or ACPI. 124.Pp 125Some i386 and amd64 BIOS implementations don't assign an interrupt for 126some devices. 127.Pp 128This option assigns an interrupt for such devices instead 129of relying upon the BIOS to do so. 130.Pp 131If a valid interrupt has already been assigned to a device, this 132option leaves the interrupt as is. 133.El 134.Sh HARDWARE 135.Nx 136includes machine-independent 137.Tn PCI 138drivers, sorted by device type and driver
