Porting VxWorks on Linux or BSD 6.x

Hello,

We have a complex VxWorks based embedded application - We want to now
switch to Linux or BSD (preferred)
I need to prototype this -

I see that MontaVista has an open Source library  @ (http://
legacy2linux.sourceforge.net/v2linux.html)  to help with this porting
-

- I have several VxWorks Tasks that would run as threads, and if we
use a multiword CPU I would expect the scheduler to schedule the
threads across the cores -

  -Can anybody share their experiences if they have done this before?
(In terms of complexity and performance)


Thanks
