Does anyone have any ideas for potential Fedora ARM related projects
that we could throw one or more students at for a 10-week block?
Thanks,

Could you be more specific? What level of student and what level of hand
holding will they need? I could come up with a number of projects but need
more details, and likely some examples to know the detail needed. Will they
have access to arm hardware to test on?

They'd be at least a sophomore in CS, and we'd ensure they had some low
level experience before hiring, so hand-holding would hopefully be at a
minimum. We would also make sure they had the necessary hardware to do
the job.

Yes. The OpenJDK Java port doesn't have a JIT compiler that works on
Raspberry Pi. The OpenJDK JIT generates Thumb2 code, and Raspberry Pi
doesn't have Thumb2, so we end up interpreting. It would be well
within the scope of a student project to fix this.
There is a simple mapping from Thumb2 to ARM code; all that is
required is to change the binary encoding generated by the back-end of
the JIT to ARM instead of Thumb2. This would result in a huge
performance boost on all Raspberry Pi-class devices. This project
would suit a capable student who has an interest in low-level
programming and isn't scared of hex dumps.
