Hi Miaoqing, I'm emailing you because I've noticed that ath9k's rng.c is the *only* driver in the whole of the tree that calls add_hwgenerator_randomness() directly, rather than going through Herbert's hw_random API, as every single other hardware RNG does. I'm wondering if you'd consider converting your driver into something suitable for the hw_random API (in drivers/char/hw_random/), rather than adhoc rolling your own ath9k rng kthread. Is this something you're actively maintaining and would be interested in doing? Regards, Jason
