+@deffn {Interface Driver} {xlnx_pcie_xvc}
+This driver supports the Xilinx Virtual Cable (XVC) over PCI Express.
+It is commonly found in Xilinx based PCI Express designs. It allows debugging
+fabric based JTAG devices such as Cortex-M1/M3 microcontrollers. Access to this is
+exposed via extended capability registers in the PCI Express configuration space.
+
+For more information see Xilinx PG245 (Section on From_PCIE_to_JTAG mode).

+@deffn {Config Command} {xlnx_pcie_xvc_config} device
+Specifies the PCI Express device via parameter @var{device} to use.
+
+The correct value for @var{device} can be obtained by looking at the output
+of lscpi -D (first column) for the corresponding device.
+
+The string will be of the format "DDDD:BB:SS.F" such as "0000:65:00.1".
