I'd like to ask about the power aware scheduler development:
https://blueprints.launchpad.net/linaro-power-kernel/+spec/power-aware- scheduler
It is present as pack small task in MP tree.
Why I'm interested?
I'd like to test and further develop methods to put CPU to IDLE or changing its operating frequency. I'm especially interested in packing as much as possible tasks to a CPU and put the other one to deep idle (RFTS - policy). I'm also curious how aggressive SCHED_POLICY_POWERSAVING is going to be? (are there any special requirements)
In the above page at the "Work items 2013.01" section states that there is a work TODO in the "max_power and current_power" for DVFS.
Could you share code (if available) and plans for this development?
I've looked to the:
git://git.linaro.org/arm/big.LITTLE/mp.git tree (branch: power-aware- scheduling-v4), but didn't find the power related code (especially DVFS).
that is the work Alex-shi is doing.
Probably I've looked at wrong place, so any guidance would be appreciate.
yes
As a side question:
On the linaro-dev mailing list there are some patches for tuning cpufreq governor. Is there any roadmap for this effort?
Which patches?
