Hi All,

           my name is Carlos Mar, I am master student of Science
Computer Department of Federal University of Amazonas - Brazil. My
research group have interest in embedded systems, particulary in power
management. I would like to know where I can found more information
about this list (todo list, projects in development, etc), is there
some web page ?
       Our group would like to participate by contributing to this
community. We can start by building a web page to provide information
about you, case it does not exist.

Best regards,

Carlos Mar

Would that happen to be in Manaus?  What kinds of platforms
are you working with?

I don't think it's that organized.  :(

Check the list archives.  Maybe you can describe a few specific
problems you're looking at, and get some discussion going there.

Hi David,

               in first place I thank to you for answer my questions.
I was very busy last days because it I am just answer you
now.

Our group, named Group of Interest in Embedded Systems (GISE), is researching
about power management and other subjects related to embedded systems.
We began our researches last year and as a first result We developed a
tool for apply Dynamic Voltage and Frequency Scale (DVFS) in C codes.
Now, We are applying this tool in real codes and doing adjusts. This
tool was developed
under open source filosofy and will be available in sourceforge even
end next month (june) . The next step to be taken for us is to
participate of groups which interest is the same ours. In a first
moment, our tool was designed to work with ARM platform, more
specifically ARM 9.

We have not a specific problem, in fact We would like contributing with
you, then We need to know how interact with you and what kind of
problem We can help.

What do you think about create a web page  to provide information
about this list and its projects ?

How is this different to the cpufreq code and governors already present 
in the Linux kernel?

Hi Matthew,

answering your question:

> How is this different to the cpufreq code and governors already present
> in the Linux kernel?

The goal of our tool is to support embedded systems developers in the
translation from their code (power unware) to a power aware code. We
consider that this developers are usually not familiar with power
management and timing constraints. Our tool performs a static analysis
of the input code in order to find places where voltage and frequency
scaling code could be included. In fact, our tool also makes use of
cpufreq libs. So, our intention is not to create another cpufreq or
anything else, but to use existing tools/libs available in the open
source community.


Regards,

Carlos Mar
