I am not sure if PCIe gen 2 requires special software support in the PCI layer, or if the hardware hides any PCIe version differences from the Linux PCI driver. PCIe 2.x works fine with Linux. We don't support all of the PCIe 2.x extensions though, so depending on your device not all features may be enabled. -- Jesse Barnes, Intel Open Source Technology Center
