But if PM_RUNTIME is enabled along with it, I don't think it will make much of a different, will it? Building the kernel with genpd and without PM_RUNTIME is possible today, but is it really useful? To me, it only seems to make people try to reinvent the wheel "because PM_RUNTIME may be unset". I have to say I'm seriously considering to make PM_SLEEP select PM_RUNTIME too as that would make quite a few things a *lot* simpler. -- I speak only for myself. Rafael J.
