These library services take a single + address parameter that encodes the PCI Segment, PCI Bus, PCI Device, PCI Function, and PCI Register. + The layout of this address parameter is as follows: + + PCI Register: Bits 0..11 + PCI Function Bits 12..14 + PCI Device Bits 15..19 + PCI Bus Bits 20..27 + Reserved Bits 28..31. Must be 0. + PCI Segment Bits 32..47 + Reserved Bits 48..63. Must be 0. + + | Reserved (MBZ) | Segment | Reserved (MBZ) | Bus | Device | Function | Register | + 63 48 47 32 31 28 27 20 19 15 14 12 11 0 + + These functions perform PCI configuration cycles using the default PCI configuration access + method. This may use I/O ports 0xCF8 and 0xCFC to perform PCI configuration accesses, or it + may use MMIO registers relative to the PcdPciExpressBaseAddress, or it may use some alternate + access method. Modules will typically use the PCI Segment Library for its PCI configuration + accesses when PCI Segments other than Segment #0 must be accessed. + +Copyright (c) 2006 - 2012, Intel Corporation.

Only those platforms that implement this protocol + will have the capability to support incompatible PCI devices. The absence of + this protocol can cause the PCI bus driver to configure these incompatible + PCI devices incorrectly. As a result, these devices may not work properly. + + The EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL is used by the PCI bus driver + to support resource allocation for some PCI devices that do not comply with the + PCI Specification. This protocol can find some incompatible PCI devices and + report their special resource requirements to the PCI bus driver. The generic + PCI bus driver does not have prior knowledge of any incompatible PCI devices. + It interfaces with the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL to find out + if a device is incompatible and to obtain the special configuration requirements + for a specific incompatible PCI device. + + This protocol is optional, and only one instance of this protocol can be present + in the system. If a platform supports this protocol, this protocol is produced + by a Driver Execution Environment (DXE) driver and must be made available before + the Boot Device Selection (BDS) phase. The PCI bus driver will look for the + presence of this protocol before it begins PCI enumeration. If this protocol + exists in a platform, it indicates that the platform has the capability to support + those incompatible PCI devices. However, final support for incompatible PCI + devices still depends on the implementation of the PCI bus driver. The PCI bus + driver may fully, partially, or not even support these incompatible devices. + + During PCI bus enumeration, the PCI bus driver will probe the PCI Base Address + Registers (BARs) for each PCI device regardless of whether the PCI device is + incompatible or not to determine the resource requirements so that the PCI bus + driver can invoke the proper PCI resources for them. Generally, this resource + information includes the following: + - Resource type + - Resource length + - Alignment + + However, some incompatible PCI devices may have special requirements. As a result, + the length or the alignment that is derived through BAR probing may not be exactly + the same as the actual resource requirement of the device. For example, there + are some devices that request I/O resources at a length of 0x100 from their I/O + BAR, but these incompatible devices will never work correctly if an odd I/O base + address, such as 0x100, 0x300, or 0x500, is assigned to the BAR. Instead, these + devices request an even base address, such as 0x200 or 0x400. The Incompatible + PCI Device Support Protocol can then be used to obtain these special resource + requirements for these incompatible PCI devices. In this way, the PCI bus driver + will take special consideration for these devices during PCI resource allocation + to ensure that they can work correctly. + + This protocol may support the following incompatible PCI BAR types: + - I/O or memory length that is different from what the BAR reports + - I/O or memory alignment that is different from what the BAR reports + - Fixed I/O or memory base address + + See the Conventional PCI Specification 3.0 for the details of how a PCI BAR + reports the resource length and the alignment that it requires. + + Copyright (c) 2007 - 2009, Intel Corporation.
