Hi all,
I ran X86 in full system with a SPLASH benchmark ocean_cp successfully.
However, when I tried to run the same benchmark with X86 full system+ Ruby.
I got this: "MP-BIOS bug: 8254 timer not connected to IO-APIC". And then
the system stalled. I wonder how to solve this problem. Thanks!
The command is :
/build/X86/gem5.fast configs/example/ruby_fs.py -b ocean_cp
