Dear PowerTOP folks,
Arjan committed in e480eb6990ece04f0f7991d0ae32e6e7b84a0d68 [1] a
suggestion to the following Linux option.
Suggestion: Enable the CONFIG_PM_ADVANCED_DEBUG kernel configuration
option.
This option will allow PowerTOP to collect runtime power management
statistics.
I have two issues regarding this.
1. I am running Debian Sid/unstable and it looks like the shipped Linux
kernel 2.6.32-5-686 [2] does not have that config option yet.
a) Could PowerTOP check what Linux version is running and notify a user
if his Linux version supports this feature? Adding to the suggestion
when the feature was introduced should be also sufficient.
b) If a) is not feasible, should I ask Debian to backport those options?
Do you know if that would be easily doable?
2. The description of this config options reads as follows [3].
Add extra sysfs attributes allowing one to access some Power
Management fields of device objects from user space. If you are
not a kernel developer interested in debugging/testing Power
Management, say "no".
Should the debugging/testing part be removed considering that it might
benefit PowerTOP users too?
Thanks,
Paul
