The PCI_IC_11 has been updated from "The PCI Express root complex is in the same Inner Shareable domain as the PEs. " to "If an I/O subsystem supports I/O Coherency, it must be in the same Inner Shareability domain as the PEs.".
That means "the I/O Coherency is not required at the BSA-level (but is required at the SBSA-level), and PCI Express root complex doesn't have to support it for the BSA compliance".
However, for now, if the PCI Express root complex doesn't support I/O Coherency, we'll get the failure below. Therefore, we need to update the BSA test 840 to match the latest PCI_IC_11 in BSA spec.
