Flexible HSIO Lane Multiplexing in PX PCH

The 8 Flexible HSIO Lanes [7:0] on PX PCH support the following configurations:

  1. Up to eight PCIe* Lanes
    • A maximum of six PCIe* Root Ports (or devices) can be enabled
      • When a GbE Port is enabled, the maximum number of PCIe* Root Ports (or devices) that can be enabled reduces based off the following:

        --> Max PCIe* Root Ports (or devices) = 6 - GbE (0 or 1)

    • PCIe* Lanes 1-4 (PCIe* Controller #1) and 5-8 (PCIe* Controller #2) must be individually configured.
  2. Up to four USB 3.2 Gen 1x1/2x1 Lanes
    • A maximum of four USB 3.2 Gen 1x1/2x1 Ports (or devices) can be enabled.
    • USB 3.2  Gen 1x1 = 5 GT/s
    • USB 3.2  Gen 2x1 = 10 GT/s
  3. Up to two GbE Lanes
    • A maximum of one GbE Port (or device) can be enabled.
  4. For unused USB 3.2/PCIe* Combo Lanes, the unused lanes must be statically assigned to PCIe* or USB 3.2 via the USB 3.2/PCIe* Combo Port Soft Straps through the Intel Flash Image Tool (FIT) tool.
