+What: /sys/class/misc/drivers/dw-xdata-pcie.<device>/write
+Date: April 2021
+KernelVersion: 5.13
+Contact: Gustavo Pimentel <gustavo.pimentel@synopsys.com>
+Description: Allows the user to enable the PCIe traffic generator which
+ will create write TLPs frames - from the Root Complex to the
+ Endpoint direction or to disable the PCIe traffic generator
+ in all directions.
+
+ Write y/1/on to enable, n/0/off to disable
+
+ Usage e.g.
+ echo 1 > /sys/class/misc/dw-xdata-pcie.<device>/write
+ or
+ echo 0 > /sys/class/misc/dw-xdata-pcie.<device>/write
+
+ The user can read the current PCIe link throughput generated
+ through this generator in MB/s.
+
+ Usage e.g.
+ cat /sys/class/misc/dw-xdata-pcie.<device>/write
+ 204
+
+ The file is read and write.
