I saw this problem as well. I don't know what's causing it. If you're
looking for ways to debug it, I'd suggest figuring out what the CPU is
doing while it's hung. Is it just waiting idle? Is it stuck in a loop?
Is it stuck at one point in time and not progressing the simulation
(unlikely)? Then try to find out what it's waiting for, if anything,
and why that hasn't happened or the CPU hasn't noticed that it happened.

I am facing the same issue as Jason mentioned with detailed CPUs. The
system boot-up seems to be going fine, but seems stuck at running INIT,
even after 2-3 hrs.

I was able to boot 8 cores using atomic but I am still working on
multicore timing or detailed models. I currently get a error when init
calls fork at the end of booting. I am trying a couple of patches from the
website to see if they will help.

Is it possible to boot more than 4 cores in x86 FS?

Gabe,
Thanks for the patch. I did a hg pull and hg update this afternoon and
have made some progress on booting. I found that with a custom built
version of 2.6.28.4 with smp on, the patch and the linux image files
(linux-bigswap2.img and linux-x86.img) from gem5.org I am able to boot
multicore x86 using the default cpu type which I think is atomic.
After working with Andrea, we noted that the boot problem for x86 happens
with the PARSEC root image but not the linux-x86.img from gem5.org.
This was tested using the custom kernel and the default cpu type.
I am currently attempting to test the detailed cpu-type with 2 cpus. I
will let you know of any errors I run into.
Thanks,
Jason Clemons

I looked into this more, and the code that sets up the memory hierarchy
was broken a little while ago. I have a patch that seems to fix it
(attached) but then it gets stuck a little later. I remember a while ago
someone had problems with atomic operations not being supported by the
memory system fully, but I don't remember the specifics. This might be
that problem too.

Yes, I have. You're using O3 though, and that support is fairly new.

Hi,
Has anyone been able to boot multiple cpus wth FS mode on x86 ? If
yes, it
would greatly help if you could share your environmental setup. The
issues
I am facing I have already posted in some previous emails.
Thanks for your help!
