This really helped to zero down my thinking between real time and
performance.
As I did not use this G1 phone, I am not sure of Android phones reliability.
May be once who used G1 phone/tested G1 phones can answer these questions

If it was as easy as pointing a finger and saying "here optimize that," then
it probably would have already been done. 90% of the effort in optimization
is figuring out exactly what is slow and can be improved. So if you want to
proceed into this -- pull out a profiler and start digging in. For

Real Time is NOT about making things "quicker". Its about reliability.
Its about providing guarantees that certain events will happen within
a particular time deadline no matter how the rest of the system is
behaving. For example, lets say there is a music application

Hi Dianne,
Even though my observations were not on the same hardware (regardless of
hardware we can make system better on sotware part to make it run better I
guess), I wanted to make Android performance faster and for that I am trying
to explore much on this Android kernel part. As kernel is take

"real time" != "better performance". It is a different approach to
scheduling work, which is not really appropriate for most uses of Android.

Hi,
Regarding Realtime patches, I was successfully able to patch it on normal
linux kernel, but was not successful when I integrate it with Android
kernel. I was able to patch and compile it, but am facing while loading the
android system. I get some errors while loading real time modules.

Yes, I agree with Greg, as 2.6 kernel versions are all *Pre-emptible* which
makes it close to real time, is'nt it ?
Any performance tools will be useful to measure. Does Android CTS will cover
some performance tests ?
We are not sure when we will get CTS in our hands also.

It is no different from real time support in any Linux system, have you
looked into the real time patchset for the Linux kernel? It should

Hi Team,
I am not able to get any leads regarding real time support in Android. I
also have a quick doubt regarding android kernel performance tools, are
there any tools that android provides for testing time taken for scheduling
a task, latency etc?
Thanks,
