What: /sys/class/misc/drivers/dw-xdata-pcie./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.
