PEX8619 PCIe switch NT mode support in VxWorks 6.9

I have 3U VPX processor blade (3rd Gen Intel Core i7 processor) with Mobile Intel QM77 Express Chipset. And the board has PEX8619 PCIe switch which is configured for non-transparent mode via the hardware strap pins and eeprom.
I would like to know whether VxWorks 6.9.x GPP version has support (driver) for Non-transparent bridging. If not, how to start writing a driver or altering the existing driver to support this.

Wrong forum I’m afraid
