Hello all,
I just want to report that we have been able to run the SPEC2000 integer
tests successfully on Linux SMP 2.6.38-rc1. After 2-3 days of running
the tests (users=2) on a dual core LEON@70MHz on Debian Etch, the
results were correct. Two months ago I was able to run for 1-2 minutes
before the system crashed in different ways or hanged.
Thanks all,
Daniel

I assume this is with the smp_call_function changes added to your tree,
right?
It would be nice to get the sun4m/sun4d bits written so I can integrate
that fix. :-)

Yes, with the patches I sent to the list. At gaisler.com distribute a
"LEON Linux 2.6.36.3" package with all the patches I used.

I agree, it's a pity I'm not so good with sun sparcs. If I find some
free time perhaps I could do an experimental implementation.. free time
has been a rarity lately, so don't expect it to happen... :)

This is very good news! Then we know a way forward how to fix
SS1000 / and likel some of the sun4m systems with > 1 processor too.

I have added this to my TODO list. But as I do not have any SMP system yet...
[Working on that]

If I take a stab on it later at least I hope you find time to review the stuff.
