> The implementation of of high resolution timers will probably need to rely on MCU HW timer and will be an optional feature. In that case, there will _have_ to be additional Kconfigs to select which HW timer provides this service. We can't just pick one because this is very arch- and chip- dependent, and some timers have special capabilities which the application may need. ARM has the SysTick timer which (if I understand correctly) doesn't have to be configured for 1 KHz operation, though that seems to be what everyone is doing. But other archs don't have such a timer and rely on peripheral timers on the SoC. Please don't misunderstand: I think it would be great to have a nicely integrated solution. I just think it will be an awful lot of work to get there. (Unless we leave it up to the board logic, but that is its own can of worms.) -- This is an automated message from the Apache Git Service.
