From the mail of Joel I know that the Google summer of code
2012 is going to start and RTEMS will be absolutely a member of
organizations. There are lots of projects i am interested in
from the Wiki open project section. The most favorite one for me
is "Bus Space API". So i want to know as much information as
possible.<br>
First i have read "Bus Space API" section carefully at the
Wiki, And also know some basic backgroud through the IRC log.
The bus_space API is originally from NetBSD, its goal is to
allow a single driver source file to manipulate a set of devices
on different system architectures, and to allow a single driver
object file to manipulate a set of devices on multiple bus types
on a single architecture. It is implemented in the BSP layer and
the architecture layer, that means different architecture and
machine must implement its own bus space type and <br>
functions. But the goal of "Bus Space API" project is to easing
the ports of BSD drivers to RTEMS, so in order to realize its
goal, should we port bus_space API to RTEMS BSP layer and
architecture layer or adapt the bus_space API in the RTEMS score
which make BSP layer and architecture layer unchanged or changed
minimum? <br>
So i want to know more information about this project, are
there some protential mentors to help me?<br>

This is indeed an important project. Unfortunately, after discussing
it with another<br>
core developer, we think it may be beyond a GSOC project. <br>
<br>
First, it requires deep knowledge across RTEMS, boards, target
architectures, etc.<br>
We are afraid that by the time we mentored you enough to solve the
problem, <br>
(1) we could have implemented it and (2) the summer would be over.
:)<br>
<br>
Another factor is that a couple of the core developers are currently
<br>
supposed to be funded to do this as soon as they finish up another
project.<br>
Based on the schedule, they should be nearly finished before the
GSOC <br>
students accepted are announced. They are only committed to
implementing<br>
the BSP/target side of this for a couple of architectures.<br>
<br></div></blockquote>Joel, thank you for your suggest. One of goals of Gsoc project is to take the students into<div>the open source development, and another goal is to benefit the organization.

This leaves you the option of proposing to implement this for the
remaining<br>
architectures. But it also puts you down stream of another schedule
which is<br>
a risk.<br>
<br>
I wouldn't want you to be at risk of even starting on time. Is there
another<br>
project you would like to do?<br></div></blockquote>Yes, except the Bus API project, I also have an interested project to participate in which is about</div><div>support the LLVM/Clang to Rtems.
