For ath6kl I started writing (but did not finish yet) a simple python plugin for trace-cmd. I really like the idea of implementing of implementing the parser with python, it's so much faster and more convenient. I haven't published the plugin yet so that's not going to help you right now. But trace-cmd documentation about python plugins should give some ideas how to use python: https://git.kernel.org/cgit/linux/kernel/git/rostedt/trace-cmd.git/tree/Documentation/README.PythonPlugin And as usual, Johannes is a good source of information ;) -- Kalle Valo -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
