Hello Everyone, Yaz: I do not change anything, I am using commit 2a98a994df296f818b05da90ba073d879562da04 of gem5.
Is there anyone who was able to *boot* the full system for x86 ISA using O3CPU? My command line : *build/X86/gem5.opt configs/example/fs.py --kernel=x86_64-vmlinux-2.6.22.9 --disk-image=linux-x86.img --cpu-type=DerivO3CPU --caches* Best regards, Abhishek On Fri, Mar 8, 2019 at 2:09 PM Ayaz Akram <aaq...@gmail.com> wrote: > Hi Abhishek, > > I wonder if you are using the default CPU configuration for full-system or > do you have any changes? > > Regards > -Ayaz > > On Wed, Mar 6, 2019 at 2:20 PM Abhishek Singh < > abhishek.singh199...@gmail.com> wrote: > >> Hello Everyone, >> >> I am trying to run the gem5 full system with X86 ISA and DerivO3CPU >> >> I have built image and kernel following Jason's Website (ref: >> http://www.lowepower.com/jason/setting-up-gem5-full-system.html) >> My image is* Ubuntu 16.04.5 LTS* >> My kernel is *Linux-4.8.13* >> Gem5 version: Latest as of 6th March 2019 >> >> The image and kernel work fine with Atomic and Timing CPU for x86. >> But for O3CPU, it gives an error as shown below: >> """"""""" >> >> command line: *./build/X86/gem5.opt configs/example/fs.py >> --script=./script.rcS >> --disk-image=/home/abs218/image_kernel/ubuntu-test.img >> --kernel=/home/abs218/new_fs/gem5/linux-4.8.13/vmlinux --caches --l2cache >> --cpu-type=DerivO3CPU* >> >> >> Global frequency set at 1000000000000 ticks per second >> >> warn: DRAM device capacity (8192 Mbytes) does not match the address range >> assigned (512 Mbytes) >> >> info: kernel located at: /home/abs218/new_fs/gem5/linux-4.8.13/vmlinux >> >> system.pc.com_1.device: Listening for connections on port 3456 >> >> 0: rtc: Real-time clock set to Sun Jan 1 00:00:00 2012 >> >> 0: system.remote_gdb: listening for remote gdb on port 7000 >> >> warn: Reading current count from inactive timer. >> >> **** REAL SIMULATION **** >> >> info: Entering event queue @ 0.
