-/*
- * Pci.c - New server PCI access functions
- *
- * The XFree86 server PCI access functions have been reimplemented as a
- * framework that allows each supported platform/OS to have their own
- * platform/OS specific pci driver.
- *
- * All of the public PCI access functions exported to the other parts of
- * the server are declared in Pci.h and defined herein. These include:
- * pciInit() - Initialize PCI access functions
- * pciFindFirst() - Find a PCI device by dev/vend id
- * pciFindNext() - Find another PCI device by dev/vend id
- * pciReadLong() - Read a 32 bit value from a device's cfg space
- * pciReadWord() - Read a 16 bit value from a device's cfg space
- * pciReadByte() - Read an 8 bit value from a device's cfg space
- * pciWriteLong() - Write a 32 bit value to a device's cfg space
- * pciWriteWord() - Write a 16 bit value to a device's cfg space
- * pciWriteByte() - Write an 8 bit value to a device's cfg space
- * pciSetBitsLong() - Write a 32 bit value against a mask
- * pciSetBitsByte() - Write an 8 bit value against a mask
- * pciTag() - Return tag for a given PCI bus, device, &
- * function
- * pciBusAddrToHostAddr() - Convert a PCI address to a host address
- * pciHostAddrToBusAddr() - Convert a host address to a PCI address
- * pciGetBaseSize() - Returns the number of bits in a PCI base
- * addr mapping
- * xf86MapPciMem() - Like xf86MapVidMem() except function expects
- * a PCI address and a PCITAG that identifies
- * a PCI device
- * xf86ReadPciBIOS() - Like xf86ReadBIOS() but can handle PCI/host
- * address translation and BIOS decode enabling
- * xf86scanpci() - Return info about all PCI devices
- * xf86GetPciDomain() - Return domain number from a PCITAG
- * xf86MapDomainMemory() - Like xf86MapPciMem() but can handle
- * domain/host address translation
- * xf86MapDomainIO() - Maps PCI I/O spaces
- * xf86ReadDomainMemory() - Like xf86ReadPciBIOS() but can handle
- * domain/host address translation
- *
- * The actual PCI backend driver is selected by the pciInit() function
- * (see below) using either compile time definitions, run-time checks,
- * or both.
- *
- * Certain generic functions are provided that make the implementation
- * of certain well behaved platforms (e.g. those supporting PCI config
- * mechanism 1 or some thing close to it) very easy.
- *
- * Less well behaved platforms/OS's can roll their own functions.
- *
- * To add support for another platform/OS, add a call to fooPciInit() within
- * pciInit() below under the correct compile time definition or run-time
- * conditional.
- *
- * The fooPciInit() procedure must do three things:
- * 1) Initialize the pciBusTable[] for all primary PCI buses including
- * the per domain PCI access functions (readLong, writeLong,
- * addrBusToHost, and addrHostToBus).
- *
- * 2) Add entries to pciBusTable[] for configured secondary buses. This
- * step may be skipped if a platform is using the generic findFirst/
- * findNext functions because these procedures will automatically
- * discover and add secondary buses dynamically.
- *
- * 3) Overide default settings for global PCI access functions if
- * required. These include pciFindFirstFP, pciFindNextFP,
- * Of course, if you choose not to use one of the generic
- * functions, you will need to provide a platform specifc replacement.

- * Compiling the following simply requires the presence of <linux/pci.c>.

- * This scheme requires that the kernel allow mmap()'ing of a host bridge's I/O
- * and memory spaces through its /proc/bus/pci/BUS/DFN entry. Which one is
- * determined by a prior ioctl().
- *
- * For the sparc64 port, this means 2.4.12 or later. For ppc, this
- * functionality is almost, but not quite there yet. Alpha and other kernel
- * ports to multi-domain architectures still need to implement this.
- *
- * This scheme is also predicated on the use of an IOADDRESS compatible type to
- * designate I/O addresses. Although IOADDRESS is defined as an unsigned
- * integral type, it is actually the virtual address of, i.e. a pointer to, the
- * I/O port to access. And so, the inX/outX macros in "compiler.h" need to be
- * #define'd appropriately (as is done on SPARC's).
- *
- * Another requirement to port this scheme to another multi-domain architecture
- * is to add the appropriate entries in the pciControllerSizes array below.
- *
- * TO DO: Address the deleterious reaction some host bridges have to master
- * aborts. This is already done for secondary PCI buses, but not yet
- * for accesses to primary buses (except for the SPARC port, where
- * master aborts are avoided during PCI scans).

- *
- * The PCI specs require that when a bus transaction remains unclaimed
- * for too long, the master entity on that bus is to cancel the
- * transaction it issued or passed on with a master abort. Two
- * outcomes are possible:
- *
- * - the master abort can be treated as an error that is propogated
- * back through the bus tree to the entity that ultimately originated
- * the transaction; or
- * - the transaction can be allowed to complete normally, which means
- * that writes are ignored and reads return all ones.
- *
- * In the first case, if the CPU happens to be at the tail end of the
- * tree path through one of its host bridges, it will be told there is
- * a hardware mal-function, despite being generated by software.
- *
- * For a software function (be it firmware, OS or userland application)
- * to determine how a PCI bus tree is populated, it must be able to
- * detect when master aborts occur. Obviously, PCI discovery is much
- * simpler when master aborts are allowed to complete normally.
- *
- * Unfortunately, a number of non-Intel PCI implementations have chosen
- * to treat master aborts as severe errors. The net effect is to
- * cripple PCI discovery algorithms in userland.
- *
- * On SPARCs, master aborts cause a number of different behaviours,
- * including delivering a signal to the userland application, rebooting
- * the system, "dropping down" to firmware, or, worst of all, bus
- * lockouts. Even in the first case, the SIGBUS signal that is
- * eventually generated isn't delivered in a timely enough fashion to
- * allow an application to reliably detect the master abort that
- * ultimately caused it.
- *
- * This can be somewhat mitigated. On all architectures, master aborts
- * that occur on secondary buses can be forced to complete normally
- * because the PCI-to-PCI bridges that serve them are governed by an
- * industry-wide specification. (This is just another way of saying
- * that whatever justification there might be for erroring out master
- * aborts is deemed by the industry as insufficient to generate more
- * PCI non-compliance than there already is...)
- *
- * This leaves us with master aborts that occur on primary buses.
- * There is no specification for host-to-PCI bridges. Bridges used in
- * SPARCs can be told to ignore all PCI errors, but not specifically
- * master aborts. Not only is this too coarse-grained, but
- * master-aborted read transactions on the primary bus end up returning
- * garbage rather than all ones.
- *
- * I have elected to work around this the only way I can think of doing
- * so right now. The following scans an additional PROM level and
- * builds a device/function map for the primary bus. I can only hope
- * this PROM information represents all devices on the primary bus,
- * rather than only a subset of them.
- *
- * Master aborts are useful in other ways too, that are not addressed
- * here. These include determining whether or not a domain provides
- * VGA, or if a PCI device actually implements PCI disablement.
