Hello,
the SMP support is work in progress so at the moment it is hard to find an area
suitable for a GSoC project from my point of view.

Hi all,
I am a 4th-year CSE BTech student and I wish to participating the GSOC-2014. I
liked the following ideas in the design header of 'Improvements to SMP support'
Processor Affinity
Global Scheduler
The scheduler API will change with the support for partitioned/clustered
scheduling.

I think RTEMS will be a good platform to experiment with hard read time SMP
schedulers once the basic work is done. All projects in this area are
challenging since it requires a fair amount of knowledge of RTEMS internals.
With respect to processor affinity for threads I am skeptical if this is useful
for schedulers with priorities:

SMP / ISR Locks
In terms of locks everything is done for now. I have an SMP rwlock
implementation from the last GSoC project that needs to be
reviewed/tested/merged. We have currently no use case for this lock, but this
will likely change if I start with the fine grained locking support:
