Dear M5,
I'm now trying to simulate a full system with more than 1 core (CPU).
With image x86_64-vmlinux-2.6.22.9, I got following messages in m5term:
markcup:~/Gem5/m5_new$ ./build/X86_FS/m5.debug configs/example/fs.py -n 4
==== m5 slave terminal: Terminal 0 ====
Linux version 2.6.22.9 (blackga@nacho) (gcc version 4.1.2 (Gentoo
4.1.2)) #2 Mon Oct 8 13:13:00 PDT 2007

Then, I follow the page
http://www.m5sim.org/wiki/index.php/Compiling_a_Linux_Kernel,
and make linux-2.6.28 image with config file for 2.6.28.4 (from
http://www.m5sim.org/Download), but it's still not working.
Dose X86 have Linux patches and modified PAL code which are like Alpha_FS?

Thank you.
