Hi Gustavo, [...] > +The interaction with this driver is done through the module parameter and > +can be changed in runtime.

The driver does not seem to offer any parameters (aside of using sysfs for runtime settings), and it also seem to only print what it's doing when debug level is enabled - unless I am missing something? [...] > +Request to stop any current TLP transfer: > +- Command: > + echo 1 > /sys/kernel/dw-xdata-pcie/stop [...] When I do the following: # echo 1 > /sys/kernel/dw-xdata-pcie/write # echo 1 > /sys/kernel/dw-xdata-pcie/stop # cat /sys/kernel/dw-xdata-pcie/write Would output from cat above simply show "0 MB/s" then? I wonder how someone using this new driver could tell whether "write" or "read" traffic generation has been enabled aside of reading the sysfs files, would adding "/sys/kernel/dw-xdata-pcie/active" be an overkill here? What do you think? Krzysztof
