podulebus -- Acorn Expansion Card bus driver SYNOPSIS
podulebus0 at ioc0 bank 4 (NetBSD/acorn26) podulebus0 at root (NetBSD/acorn32) DESCRIPTION
The podulebus driver handles the expansion-card interface in Archimedes machines and their successors. This includes conventional expansion cards, mini expansion cards (as introduced in the A3000), network expansion cards (as introduced in the A3020), DEBI expansion cards (as introduced in the Risc PC), and Mk II network cards (also introduced in the Risc PC). Drivers for individual cards attach as children of the podulebus device. NetBSD includes several machine-independent expansion card device drivers. There are also some device drivers which are specific to NetBSD/acorn26 or NetBSD/acorn32. HARDWARE

CARDBUS(4)						   BSD Kernel Interfaces Manual 						CARDBUS(4)

cardbus, cardslot, cbb -- CardBus driver SYNOPSIS
cbb* at pci? dev? function ? cardslot* at cbb? cardbus* at cardslot? pcmcia* at cardslot? XX* at cardbus? function ? DESCRIPTION
NetBSD provides machine-independent bus support and drivers for CardBus devices. The cbb device represents the CardBus controller. Each controller has a number of slots, represented by the cardslot devices. A slot can have either a CardBus card or a PCMCIA card, which are attached with the cardbus or pcmcia devices, respectively. SUPPORTED DEVICES
NetBSD includes the following machine-independent CardBus drivers, sorted by function and driver name: Network interfaces ath Atheros 5210/5211/5212 802.11 atw ADMtek ADM8211 (802.11) ex 3Com 3c575TX and 3c575BTX fxp Intel i8255x ral Ralink Technology RT25x0 (802.11) rtk Realtek 8129/8139 rtw Realtek 8180L (802.11) tlp DECchip 21143 Serial interfaces com Modems and serial cards SCSI controllers adv AdvanSys 1200[A,B], 9xx[U,UA] ahc Adaptec ADP-1480 njs Workbit NinjaSCSI-32 USB controllers ehci Enhanced Host Controller (2.0) ohci Open Host Controller uhci Universal Host Controller IEEE1394 controllers fwohci OHCI controller Disk and tape controllers siisata Silicon Image SATA-II controllers. DIAGNOSTICS
cbb devices may not be properly handled by the system BIOS on i386-family systems. If, on an i386-family system, the cbb driver reports cbb0: NOT USED because of unconfigured interrupt then enabling options PCI_ADDR_FIXUP options PCI_BUS_FIXUP options PCI_INTR_FIXUP or (if ACPI is in use) options PCI_INTR_FIXUP_DISABLED in the kernel configuration might be of use.

The cardbus driver appeared in NetBSD 1.5. BUGS
Memory space conflicts NetBSD maps memory on Cardbus and PCMCIA cards in order to access the cards (including reading CIS tuples on PCMCIA cards) and access the devices using the RBUS abstraction. When the mapping does not work, PCMCIA cards are typically ignored on insert, and Cardbus cards are rec- ognized but nonfunctional. On i386, the kernel has a heuristic to choose a memory address for mapping, defaulting to 1 GB, but choosing 0.5 GB on machines with less than 192 MB RAM and 2 GB on machines with more than 1 GB of RAM. The intent is to use an address that is larger than available RAM, but low enough to work; some systems seem to have trouble with addresses requiring more than 20 address lines. On i386, the following kernel configuration line disables the heuristics and forces Cardbus memory space to be mapped at 512M; this value makes Card- bus support (including PCMCIA attachment under a cbb) work on some notebook models, including the IBM Thinkpad 600E (2645-4AU) and the Compaq ARMADA M700: options RBUS_MIN_START="0x20000000" BSD
