Thank you Ken & San for the replies. I want to make a process move between
two cgroups depending on a value from a sensor(GPS) So I need to automate
it, with out user issuing echo. How to get around this? kernel module or
hard coding it in sched.c or cgroup.c..

Make sure you have
http://git.android-x86.org/?p=kernel/common.git;a=commit;h=5038d42d2e60c855cf5b097197d95adaa1269d32
The code-change also should make it somewhat clearer on how the checks end
up happening.
Cheers,
-san

Thank you Ken for the reply. I created a cgroup under /dev/cpuctl and added
a process to the tasks file. using echo PID > tasks. however it wont get
registered there, of course the PID changes every time when the application
is re-started. In my case I was testing with browser and the music player.
Currently, Android dalvik VM leverages cpu cgroup to determine whether to
use kernel scheduler policies, /dev/cpuctl is mounted in init.rc by
default. You can create a sub-cpu cgroup under /dev/cpuctl, and control the
priorization of processes there as long as your process is granted with
CAP_SYS_N
after some googling came to know that android framework is it self using
cgroups. Is it the reason for the device or resource busy error?
Dose it mean that I won't be able to use cgroups?

Hi,
I have trouble configuring cgroups, please help! When I issue the
following command I get the error "mount: Device or resource busy"
# mount -t cgroup -ocpu none /dev/cpuctl
These are the configurations options that I have enabled.
CONFIG_GROUP_SCHED=y
CONFIG_FAIR_GROUP_SCHED=y
CONFIG_RT_GR
