So I have a couple of thoughts here: (1) if this is intended for qtests, would exposing the period (i.e. QOM equivalent of clock_get() rather than clock_get_hz()) be better? A Hz figure has rounding so it's not as accurate. (2) We should document this in clocks.rst; I guess we want to say "only intended for use in qtests" (i.e. if you're part of QEMU use the existing function interface, not this). thanks -- PMM
