In the early pci period, the system is only 256 memory size assigned to each pci device. to the later pcie period, as the performance of the device is enhanced, the configuration space of the pcie device extends to 4k bytes. be careful here: pcie supports 256 bus, 32 devs, 8 funs.

Type 1 pci configuration space header. the pci configuration space consists of three primary parts, illustrated in the following table. This page documents the structure and organization of the pci configuration space as implemented in the pciutils library. for information about methods to access the pci configuration space on different operating systems, see pci access methods. Intel architecture provides two port address 0xcfc (config data port) & 0xcf8 (config address port) to access the config space of the pci device.

We can view the configuration space for a certain device with windbg, which i will show later in the windbg extensions section of this post. The configuration space is typically 256 bytes, and can be accessed with read/write configuration cycles. the target device for the configuration space access is selected with the initialization device select (idsel) signal, which is then decoded by the target device. The original pci configuration space was for 256 bytes. this is now extended to 4096 bytes, with the first 256 bytes for pci and the rest for pcie extended capabilities.
