PCI Express 6.x Retimer specification Question about UIO

Hi,

The PCIe Express 6.0 Retimer Supplemental Features and Standard BGA Footprint Specification Revision 1.0 mentioned that retimer supports Unordered IO (UIO) is required.

But UIO is not physical layer aware, can you help to point out what retimer need to do to support UIO?

Many thanks.

BR,

Jerry
