I would like to hack in to two andorid devices, mic and the GPS
device. With the mic I want to get the back ground noise. Measure the
intensity of sound for ex - lets say frequency or some dB value (which
ever is supported). With GPS obviously the location cordinates.
On the android platform it is
Hi,
I want to renice the value of a process depending on a sensor
value(GPS), with out issuing the renice cmd. How can this be achieved?
writing a kernel module? a shell script(are they possible??)

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

Hi,
I am trying to implement a system call for testing, called test1. I am
getting this error.
Can someone tell how to over come this.
arch/arm/kernel/built-in.o: In function `__sys_trace_return':
io.c:(.text+0xd28): undefined reference to `sys_test1'
Thanks

Hi,
How dose android handle swap in/ swap out of its applications on
memory? What is the function call that handles this(at kernel level)?
Thanks in advance.

Thanks Tim for the insights. I thought pre-scheduling would, putting
it into the run queue would load the apps in to memory because they
are in the running state(not actually running but ready to run) isn't
that the case. My question dosen't pre-scheduling do the read ahead?
Thanks for pointing th
Hi,
Is it possible to access the GPS device driver (inside the kernel) and
get the sensor values from the device driver?

How to access the accelerometer at the kernel level and read its
values. For example to identify if the user is standing(stationary) or
driving (moving). I think I think will have to deal with device
drivers, found this post

but it
Android scheduler is using the Completely Fair Scheduling(CFS) right?
I would like to know how to add a process (application) to the rbtree
(the runqueue)? I would like to know how this can be done, before the
user starting that process.

Hi,
I had a similar issue in downloading the kernel source from
http://source.android.com/source/downloading.html . What I did after
the successful download was to checkout the right branch. Then got the
source files.
git branch -r (will list the remote branches)
git checkout -t origin/android-g
