Even though full system simulations have been allowed with O3 CPU and
Ruby, it may not necessarily work out right now. We are still discussing
some patches about the O3 CPU which may improve the situation.

Hi,
I'm trying to use O3CPU and Ruby FS config in gem5 but before linux boots
up completely, I get following panic:
"panic: Unable to find destination for addr 0x100000008
@ cycle 172076977000
[findPort:build_alpha_fs_moesi_cmp_dir/build/ALPHA_FS_MOESI_CMP_directory/mem/bus.cc,
line 359]
Memory Usage: 3951952 KBytes"
This happens in I/O section of the bootup. Following are the last few lines
in system.terminal:
NET: Registered protocol family 16
EISA bus registered
pci: enabling save/restore of SRM state
SCSI subsystem initialized
I tried to run making flag use_default_range = False but that gives panic
at some other place.
I'm using linux kernel available on website and I increased memory size to
3GB.
Is O3CPU+Ruby FS stable gem5 config to use?
Is it a known issue?
I'd appreciate any help on this.
Thanks,
Ripudaman Singh
