hi,

I am trying to use some IBM rt test on arm.


I define atomic_add to
assert(i==1);
return ++(v->counter);

That's a bit ugly, but that should work for my need.

But I have a problem with the sched_latency test.
On my platform the thread creation is quite slow (25ms), so with the 
default value, I got a PERIOD MISSED.

I wonder why the test account thread creation time and not compute start 
at the beginning of the thread ?

Also my cpu is quite slow (compared to last intel core or powerpc). For 
example a sched_jitter run take 6s.
Couldn't be some static or runtime configuration to configure the test 
according to the cpu speed ?
