Please read on. There's currently no facility to push sample rate requests down into the kernel from userspace. However, this is a good idea in general - there was some recent (brief) discussion of doing this on the linux-input list. Since different use cases have different sample rate requirements (such as the difference between handwriting recognition which can need 200 samples/second and a simple finger operated menu which may be happy with 10) there's value in being able to vary the sample rate at run time. I was intending to look at this shortly as part of some touchscreen driver development I need to do soon or perhaps someone else will pick up the idea, if it does get implemented then obviously tslib would also be able to use it here. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
