[gem5-users] Full System Simulation complains about a missing "vmlinux.aarch32.ll_20131205.0-gem5"

[Amine Marref]

Dear All,

I am trying to use gem5 in FS mode. When I pass the disk image's name to
the simulation command, I get the error message " IOError: Can't find file
'vmlinux.aarch32.ll_20131205.0-gem5' on path".

The disk image I am running is the one from the archive "
aarch-system-20180409.tar.xz
<http://www.gem5.org/dist/current/arm/aarch-system-20180409.tar.xz>" which
does not contain the file mentioned in the error message.

Furthermore, I have used the flags --disk-image, --kernel, and --dtb to
specify exactly the images/binaries that need to be used; however, with no
luck.

My M5_PATH is set correctly.

In [1-5] below, I show relevant information to the issue.

I also downloaded the system images contained in the archive "
aarch-system-2014-10.tar.xz
<http://www.gem5.org/dist/current/arm/aarch-system-2014-10.tar.xz>" (which
contains the file mentioned in the error message), set the M5_PATH to point
to the new location, and ran FS simulation. This time it did not produce
the previous error message, but simulation got stuck after producing the
message "Kernel panic in simulated kernel".

I too am stuck. Any ideas?

I am running gem version 2.0 inside a virtual machine of Ubuntu 16.04.

Thanks,
Amine.

Amine,

Two possible things:

One: set M5_PATH environment variable
Two: modify configs/common/SysPath.py and edit the path and remove /m5 and add your own path

Try one of them or both fixes.


Regards,
Luis Vitorio.

You should check in the configs/common/FSConfig.py. The kernel and dtb
names are mentioned there. The default names are set according to the 2014
image files. Since you are using the 2018 image, so gem5 is not able to
load your kernels and images.
You can do this:
1. Modify the names in FSConfig.py according to your downloaded images and
kernels.
2. Download the default one.

As you also mentioned that you have tried out the 2014 files, you should
again go check if all the files mentioned in FSConfig.py are matching
(kernel binaries and dtbs).

Thanks everyone,

Specifying the correct combination of disk, machine, kernel, and dtb
combination worked for me to start FS simulation mode. Hopefully, somebody
at some point writes a little wiki on the allowed combinations of these
files.

In summary, first, the M5_PATH must be set:
echo "export M5_PATH=/path/to/aarch-system-20180409/" >> ~/.bashrc
source ~/.bashrc

Second, the following are passed to the simulation script.
--disk-image=aarch64-ubuntu-trusty-headless.img
--machine-type=VExpress_GEM5_V1 --dtb=armv8_gem5_v1_1cpu.dtb
--kernel=vmlinux.vexpress_gem5_v1_64

There was no need to edit the default values in FSConfig.py.

You should check in the configs/common/FSConfig.py. The kernel and dtb
names are mentioned there. The default names are set according to the 2014
image files. Since you are using the 2018 image, so gem5 is not able to
load your kernels and images.
1. Modify the names in FSConfig.py according to your downloaded images and
kernels.
2. Download the default one.
As you also mentioned that you have tried out the 2014 files, you should
again go check if all the files mentioned in FSConfig.py are matching
(kernel binaries and dtbs).

Amine,
One: set M5_PATH environment variable
Two: modify configs/common/SysPath.py and edit the path and remove /m5
and add your own path
Try one of them or both fixes.

Luis Vitorio.

Subject: [EXT] [gem5-users] Full System Simulation complains about a
missing "vmlinux.aarch32.ll_20131205.0-gem5"
Dear All,
I am trying to use gem5 in FS mode. When I pass the disk image's name to
the simulation command, I get the error message " IOError: Can't find file
'vmlinux.aarch32.ll_20131205.0-gem5' on path".
The disk image I am running is the one from the archive "
http://www.gem5.org/dist/current/arm/aarch-system-20180409.tar.xz" which
does not contain the file mentioned in the error message.
Furthermore, I have used the flags --disk-image, --kernel, and --dtb to
specify exactly the images/binaries that need to be used; however, with no
luck.
My M5_PATH is set correctly.
In [1-5] below, I show relevant information to the issue.
I also downloaded the system images contained in the archive "
http://www.gem5.org/dist/current/arm/aarch-system-2014-10.tar.xz" (which
contains the file mentioned in the error message), set the M5_PATH to point
to the new location, and ran FS simulation. This time it did not produce
the previous error message, but simulation got stuck after producing the
message "Kernel panic in simulated kernel".
I too am stuck. Any ideas?
I am running gem version 2.0 inside a virtual machine of Ubuntu 16.04.
Thanks,
Amine.
[1] The variable M5_PATH is set correctly.
