[Dynamicpower-devel] DPM questions

[Daniel P. <d.p...@gm...>]

Hi all,

I've been researching the DPM for omap platform. In my tests I
switched the policies created in the dpm-setup-omap1510 script and
could realize the frequency switching. I also created some lower
frequency OPs - big power savings :-)
In my group, I was assigned to make more tests and understand DPM deeply.
I have some doubts and appreciate very much if someone can help.

-How can I assign an user process to a operating state (task-4,
task-3...task, task+3, task+4)? Reading /proc/driver/dpm/stats I see
that the system only switches among idle, idle-task and task.  How can
I start a process  in task-4 state for instance?

-Is there any user level application or deamon that runs and manage
the task assignment, a test policy manager already developed?

-Which are the operating points parameters: tc_rate, mpuper_rate and dsp_rate?


Thank very much in advance and best regards,
 

Daniel Petrini
