* 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. - * - * Gary Barton - * Concurrent Computer Corporation - * garyb@gate.net - * - */ - -/* - * Copyright 1998 by Concurrent Computer Corporation - * - * Permission to use, copy, modify, distribute, and sell this software - * and its documentation for any purpose is hereby granted without fee, - * provided that the above copyright notice appear in all copies and that - * both that copyright notice and this permission notice appear in - * supporting documentation, and that the name of Concurrent Computer - * Corporation not be used in advertising or publicity pertaining to - * distribution of the software without specific, written prior - * permission.

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. - * - * --- TSI @ UQV 2001.09.19 - */ - for (node2 = promGetChild(node); - node2;
