I think the assembly part should be a smaller issue, certainly a solvable one. You are invited to post your questions regarding this here (or better on xenomai-core) so that we all can try to look at it. /me has no x86-64 assembly experience yet, but I think to remember that it's very similar to well-know i386. The bigger issue with such ports are the testing/debugging cycles which can cost quite some time if you are unlucky (or blind, or both ;)). >=20 >> [Really, it depends on someone feeling enough need to work on this (or= >> sponsor the work).

I would consider it as an inspiration for certain detail problems, also regarding the assembly stuff. But the overall design is of no use because it's old-style Adeos and likely has RTAI hacks included. >=20 > (I may well have an AMD64 socket 939 processor available for loan next = week if=20 > that would help). Thanks, but for me this wouldn't change the situation.
