Hi,all
I need to run SPEC CPU2000 in FS mode with multi cores system(4 cores
at this moment). I choose ARM_FS. From the document from wiki, I downloaded:
ARM New Full System
Files<http://www.m5sim.org/dist/current/arm/arm-system-2011-08.tar.bz2>--
Pre-compiled Linux kernel, and file systems, and kernel config files.
This includes both a cut-down linux and a full ubuntu linux
Put it under the main directory of gem5.
I also created a new bigger disk image following the
http://gem5.org/Ubuntu_Disk_Image_for_ARM_Full_System
I am confused about the steps to running SPEC in FS mode.
From my understanding of Running SPEC in ARM_FS mode, I need
1. copy all arm binaries of SPEC 2000 benchmarks and the input set to
the disk image.
Question: Is there any requirement for the SPEC directory structure
I need to create in disk image?
2.Enable smp support
Question: how to realize smp support?
3. "build the boot loader in system/arm and place it somewhere gem5 can
find it."
Question: I saw this from a previous topic" ARM MP FS" in gem5
mail list, however I am not quite clear of what does it really mean.
In system/arm , there is a sub directory
"simple_bootloader", what is the function of this? Can I use it directly
instead of building a new boot loader?
4.Command line:
build/ARM_FS/gem5.opt configs/example/fs.py -n NUM_CPUS
--script= runscript.rcs --detailed --caches
I think I should include the simulation information like which
benchmark to running and which input file to use in the .rcs file, is that
right?
Is there any reference and guide about how to write the
runscript.rcs file for SPEC benchmark in FS mode?
If the command line I mentioned is wrong, what should be the right
command line for running SPEC benchmark in FS mode?
5. There is a directory "boot" under gem5/configs. It included several
.rcs file. Is it for FS mode simulation? What is the function of them?
Thanks in advance.
Any suggestion for running SPEC benchmark in FS mode is appreciated.
