May 15, 2020 · Every PCIe device has a configuration space.

Table 1.

Nov 2, 2021 · The PCI Express bus extends the Configuration Space from 256 bytes to 4096 bytes.

The smallest address range that can be allocated is 4 KB, so BARs do not contain bits 11:2, only MSB down to 12. The adapter can be used in either an x8 or x16 PCIe slot in the system.

The ECAM can access all of the space. Switch/bridge devices support multiple links, and implement a Type 1 format header for each link interface.

Type 1 Config Space is for PCI host controller and, for PCI Root Complex in case of PCIe.

This extended configuration space cannot be accessed using the legacy PCI method (through ports 0xCF8 and 0xCFC).

This extended configuration space cannot be accessed using the legacy PCI method (through ports 0xCF8 and 0xCFC). Jan 23, 2014 · The PCI Configuration Space is a set of registers, on PCI Express (PCIe) buses, this configuration space may be referred to as the the Extended Configuration Space. You can find out more about the nitty gritty of them elsewhere, but I want to emphasize that both RC and EP devices have them, with the only difference being that EP uses a Type 0 Header and RC uses a Type 1 Header.
