[fpc-pascal]OT: Linux SMP question

[md]

Marco is correct if you want realtime aspects considered.

But if you must lock down a single cpu, then you must
edit/recompile/test/debug kernel source.  That may
be more of a burden that it is worth.

Better to use the realtime queue to approximate your scheduling needs
with little debug than to 
alter the scheduler for whatever it is you are seeking to do?

In a very abstract way, what are you trying to do that requires CPU
lockdown?
