I've found only this about the dynamic tick: http://lwn.net/Articles/138969/ and it seems that it is intended only to slow down the interrupts when there is no work to do, rather than to allow setting an arbitrary frequencies or something like that. I guess now I realized how you (and Nish) assume I could use it: is it that I should set CONFIG_HZ to the value I need at compile-time, and just remove all the timer reprogramming from the driver in a hope the dynamic-tick patch will slow it down itself when necessary? Or am I misunderstanding the suggestion? That would be really excellent, but it there a patch around that allows to set an arbitrary CONFIG_HZ values, or should I try to code up one myself? I think I tried that a few years ago, and the code all around the kernel was resisting to work with HZ>1000, but I guess now it was all changed.
