[gem5-users] Re: AttributeError when using my own binary
Thanks Ziyao,
Gem5 does not support macOS syscall emulation (nor it supports Mac-O loading)..
You can still run a gem5 simulation on macOS but you should compile the binary
for a linux target (I don’t know If it possible to cross-compile on the M1 to
aarch64-linux, but you can definitely (cross)compile it on a different Linux
machine)
Hope it helps

Hi Giacomo,
Oh I'm sorry for that confusion. The FS_ruby.py is my modified script which I
forgot to change the name, it's actually a SE workload and works fine with the
Gem5 provided hello binary (gem5/tests/test-progs/hello/bin/arm/linux/hello).
Here is the code snippet of that script
binary = os.path.join('gem5/assembly/test')
# Create a process for a simple "multi-threaded" application
process = Process()
# Set the command
# cmd is a list which begins with the executable (like argv)
process.cmd = [binary]
# Set the cpu to use the process as its workload and create thread contexts
for cpu in system.cpu:
cpu.workload = process
cpu.createThreads()
system.workload = SEWorkload.init_compatible(binary)
The gem5/assembly/test executes successfully on my local environment, and I'm
using M1 arm64 cpu
Thanks,
Ziyao

Hi,
If the command line is just
$ build/ARM_MESI/gem5.opt configs/FS_ruby.py,
Are you sure you are passing the object file to the Workload object?
(_is_compatible_with is called with a None object)
Also the script is called FS ruby but you seem to have instantiated a SE
workload (ArmSeWorkload).
There’s something wrong in the custom script…
Kind Regards

Subject: [gem5-users] AttributeError when using my own binary
Hi all,
I'm currently working on ISA-level tasks and have generated my own binary using
an assembler and linker. The binary executes successfully on my local
environment (M1 ARM). However, when I attempt to run it on gem5, it fails to be
recognized.
I used the following commands to assemble and link a simple "Hello World"
assembly code (test.s):
$ as -arch arm64 -o test.o test.s
$ ld test.o -o test -l System -syslibroot `xcrun -sdk macosx --show-sdk-path`
-e _start -arch arm64
$ ./test
Hello World!
While this works well on my local environment, I encounter an error when
executing it in gem5 using the command:
$ build/ARM_MESI/gem5.opt configs/FS_ruby.py
The error message I receive is as follows:
AttributeError: 'NoneType' object has no attribute 'get_arch'
At:
build/ARM_MESI/arch/arm/ArmSeWorkload.py(43): _is_compatible_with
build/ARM_MESI/sim/Workload.py(91):
build/ARM_MESI/sim/Workload.py(91): find_compatible
build/ARM_MESI/sim/Workload.py(100): init_compatible
configs/FS_ruby.py(109):
build/ARM_MESI/python/m5/main.py(434): main
I would greatly appreciate it if anyone who has encountered a similar issue
could provide some insights or guidance.
Thank you,
Ziyao
