Hello,
I have a few ideas/questions about some power management-related issues:
1) How could we get the current frequency/voltage settings for the CPU,
fr example when using SpeedStep by using the /proc filesystem?
2) It would be nice to modify a bit the CPU throttling API to be able to
set a max value when using dynamic governors, like ondemand.
The frequency/voltage pair should be set to the minimum allowed by
construction, just like it was before, and scale up to a max value set
by the user. This would allow the user set the best balance between
responsiveness and power consumption that suits its needs.
Also, targeting a certain temperature would be a great feature to have.
3) Is there any plan to improve the current battery framework and
provide information about the estimated recharging time, as it was
before. I guess the versions before 2.6.24 used to provide this but the
newer versions don't do it anymore.
Thanks,
Cristi
