Provides services to access PCI Configuration Space.
|
||||
|
||||
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 Library for its PCI configuration
|
||||
accesses. However, if a module requires a mix of PCI access methods, the PCI CF8 Library or
|
||||
PCI Express Library may be used in conjunction with the PCI Library. The functionality of
|
||||
these three libraries is identical. The PCI CF8 Library and PCI Express Library simply use
|
||||
explicit access methods.
