Hello, I am a new user of gem5 and am attempting to familiarize myself with the tool. The computer I'm using is running Ubuntu 12.10, 64 bit. With a fresh install of Ubuntu complete, I ran the following:
cd ~ sudo apt-get install mercurial sudo apt-get install scons swig gcc python m4 python-dev libgoogle-perftools-dev zlib-dev hg clone http://repo.gem5.org/gem5 cd gem5 hg pull hg update scons build/ARM/gem5.opt build/ARM/gem5.opt configs/example/se.py -c tests/test-progs/hello/bin/arm/linux/hello This works and I am happy. Now I want to the full system emulation, as per http://www.m5sim.org/Running_gem5#Full_System_.28FS.29_Mode I download and extract the images, cd /home/bpayne/full_system_for_gem5/ wget http://www.m5sim.org/dist/current/x86/x86-system.tar.bz2 wget http://www.m5sim.org/dist/current/x86/config-x86.tar.bz2 tar jxf x86-system.tar.bz2 tar jxf config-x86.tar.bz2 Then I try to use these disks as follows: bpayne@ubuntu:~/gem5$ ./build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/bpayne/full_system_for_gem5/disks/arm-ubuntu-natty-headless.img gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Oct 11 2012 17:19:58 gem5 started Oct 12 2012 12:52:58 gem5 executing on ubuntu command line: ./build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/bpayne/full_system_for_gem5/disks/arm-ubuntu-natty-headless.img Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/bpayne/gem5/src/python/m5/main.py", line 359, in main exec filecode in scope File "configs/example/fs.py", line 106, in <module> bare_metal=options.bare_metal) File "/home/bpayne/gem5/configs/common/FSConfig.py", line 263, in makeArmSystem self.cf0.childImage(mdesc.disk()) File "/home/bpayne/gem5/configs/common/Benchmarks.py", line 53, in disk return disk(self.diskname) File "/home/bpayne/gem5/configs/common/SysPaths.py", line 37, in disk system() File "/home/bpayne/gem5/configs/common/SysPaths.py", line 59, in system raise ImportError, "Can't find a path to system files." ImportError: Can't find a path to system files. I suspect I need to specify where the disk lives, but I'm not sure how to do this correctly. Searching this email list doesn't return any useful pages as far as I can tell. http://search.gmane.org/?query=disk+image&group=gmane.comp.emulators.m5.users Thank you in advance, Ben Payne PS: the video tutorials on the wiki are useful, even if the sound quality isn't great. Any plans for a webcast or more video tutorials?
