Hello all,
I have a huge problem and don't know how to solve it. I hope you can
help me.
I use M5 with the alpha architecture. I try to make some SPEC2000
benchmarks using the full system mode. My problem is that e.g. gzip
needs more than the standard 128 MB of memory. When I set:
self.physmem = PhysicalMemory(range = AddrRange('256MB'))
instead of using
self.physmem = PhysicalMemory(range = AddrRange(mdesc.mem()))
in fsconfig.py I get the following error:
panic: Unable to find destination for addr 0xf9b6000
@ cycle 1700515217000
[findPort:build/ALPHA_FS/mem/bus.cc, line 356]
Memory Usage: 383196 KBytes
For more information see: http://www.m5sim.org/panic/3519f931
Program aborted at cycle 1700515217000
Aborted
Looking into the output of m5term the error occures during the boot process:
...
hda: M5 IDE Disk, ATA DISK drive
hdb: M5 IDE Disk, ATA DISK drive
ide0 at 0x8410-0x8417,0x8422 on irq 31
hda: max request size: 128KiB
hda: 204624 sectors (104 MB), CHS=203/16/63, UDMA(33)
hda: cache flushes not supported
hda:
I really don't know why the adjustment of the memory size to 256 MB (128
MB is standard) leads to this error. Has someone an idea how I can fix that?
Thanks a lot in advance.
Fabian
