NAME

     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.

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

NAME

     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)

	   fxp	    Intel i8255x
	   ral	    Ralink Technology RT25x0 (802.11)
	   rtk	    Realtek 8129/8139
	   rtw	    Realtek 8180L (802.11)
	   tlp	    DECchip 21143

   Serial interfaces

	   ahc	    Adaptec ADP-1480
	   njs	    Workbit NinjaSCSI-32

   USB controllers
	   ehci     Enhanced Host Controller (2.0)

	   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.

HISTORY

     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"
