Hi guys,
I'm trying to run M5 full system simulation with physical memory range bigger
than 1GB (e.g. 2GB).
The following is the only thing that I changed in fs.py for runing M5 with 2GB
physical memory:
- test_sys.physmem.range = AddrRange('1024MB')
+ test_sys.physmem.range = AddrRange('2049MB')
Then I got the following error message:
Unable to handle kernel paging request at virtual address 0000000002bf6740
I also got this message: memsize FFFFFFFF80100000 pages FFFFFFFFFFFC0080
The value FFFFFFFF80100000 should be 80100000, right?
Does anyone get this error message before?
Please help me out!
Below is the detailed information:
