RTEMS/LEON3 on Qemu

[Karel Gardas]

Folks,

I've seen this thread: RTEMS simulation of LEON3 over QEMU -- here 
http://lists.rtems.org/pipermail/users/2014-February/027560.html and I'm 
curious if anybody here already has given a try to LEON3/RTEMS on Qemu.

Particularly I would appreciate just a note if LEON3/Qemu required 
patches are already merged into Qemu head or not.. The patches are 
mentioned here by Sebastian: 
http://lists.rtems.org/pipermail/users/2014-February/027561.html

Also Sebastian mentions special LEON3 Qemu BSP is needed in his email 
here: http://lists.rtems.org/pipermail/users/2014-February/027562.html

The link is no longer valid but perhaps originally pointed here:
http://lists.rtems.org/pipermail/devel/2014-February/005283.html -- 
[PATCH] bsp/leon3_qemu: New BSP variant

At the end of the thread it looks like BSP originally submitted and 
committed is reverted and the project hangs kind of in the air waiting 
for Qemu to merge some patches but also mentioning that Qemu development 
process is not well managed and that it takes a lot of effort to push 
even simplest patches in.

So is real closure of all this that RTEMS/LEON3 is not runable on Qemu 
HEAD? If so, then I'm happy to patch Qemu with required patches but I'm 
kind of confused by a state of RTEMS on Leon3: may I use or rather not 
Sebastian's LEON_QEMU BSP? Is it uptodate or already sources diverted a 
lot so it's not applicable anymore? Or shall I use some el-cheapo FPGA 
board supporting LEON3 and use that for running RTEMS? What's current 
recommended way for RTEMS/LEON3 development?

Thanks!
Karel
