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.
