Hi Pau,
It seems like this is a bit more complicated than I anticipated. The
dist files are too big to be handled by the wiki, so they are apparently
stored as static files in the file system on the web server. I'll have
to make some enquiries and get back to you.
I think putting the script in util would make a lot of sense.
Cheers,
Andreas

Hi Andreas,
My username for the gem5 wiki is Pcabre
I agree that it makes sense to have something that gets distributed with gem5
that automatically builds the kernels, the bootloaders and the DTBs (disk
images may be another story though).
Were you thinking about something like a python script in the "util" directory?
If yes, I should be able to do it.
Thanks,
Pau

Hi Pau,
Thanks for creating these instructions and Dockerfiles! This is something that
has been on my todo/wish list for a very long time.
I should be able to give you the permissions necessary to upload the system
image to the wiki. Do you have a user name that I can bless?
It'd be nice if we could standardise and automate the process of updating the
distribution binaries using a set of scripts that get distributed with gem5.
Docker is very convenient, but is a bit of overkill if you already have the
necessary environment up and running on your workstation. The Docker script
could then reuse these scripts for automation. This would be a much appreciated
contribution. How would you feel about contributing these scripts in that way?
Cheers,
Andreas

Hi all,
I made some changes to the Dockerfile in order to generated DTBs and kernel
filenames more in accordance with the current names in
aarch-system-2014-10.tar.xz.
The newly generated files can be found here:
https://github.com/metempsy/gem5_arm_fullsystem_files_generator/releas
es/download/20170421/aarch-system-20170421.tar.xz
I have also just pushed a changeset to gerrit in order to use these
new files: https://gem5-review.googlesource.com/2841
With these changes, if the new filenames are not found, the old ones will be
used.
If the changes get accepted, it would be good to copy the
aarch-system-20170421.tar.xz file to somewhere in the gem5.org wiki.
Thanks,
Pau

(aarch-system-2014-10.tar.xz)
Hi Mohammad,
I have posted a Dockerfile to generate up-to-date arm full system
files (to the best of my knowledge) in this repository:
https://github.com/metempsy/gem5_arm_fullsystem_files_generator/
You can also directly access the generated files here:
https://github.com/metempsy/gem5_arm_fullsystem_files_generator/releas
es/download/201704/aarch-system-2017-04.tar.xz
The README.md has some information and command line examples for using the new
files.
Please feel free to try/modify them and provide any feedback.
If everybody agrees with these new files, ideally we should upload the released
.tar.xz file to the gem5.org wiki and do some small changes to FSConfig.py in
order to use the new files by default.
Thank you very much!
Pau

Thanks a lot for bringing this up. I wanted to start such conversation for a
long time as all the full system files in the webpage are deprecated.
Thank you,

Hi all,
I would like to start a discussion about updating the
http://www.gem5.org/dist/current/arm/aarch-system-2014-10.tar.xz
file, which should contain the necessary files for running arm
FullSystem simulations.
To the best of my knowledge, it has at least a couple of deprecated files:
1) binaries/boot_emm.arm64 (generated from
system/arm/aarch64_bootloader/boot.S, which got updated on
2015-07-15)
2) binaries/vexpress.aarch64.20140821.dtb (it has a misconfiguration,
as explained by Andreas Sandberg here =>
http://www.mail-archive.com/[email protected]/msg18440.html)
And I also suspect that the /sbin/m5 binary of the images in the
disks directory is not compatible anymore with the current m5
initparam pseudo-instruction, as I am getting the following assertion
failure when trying to use it in a simulated system of
aarch64-ubuntu-trusty-headless.img:
gem5.opt: build/ARM/sim/pseudo_inst.cc:398: uint64_t
PseudoInst::initParam(ThreadContext*, uint64_t, uint64_t): Assertion
`key_str2 == 0' failed.
Given this, I think that it would be good to update such deprecated
files, and it would be also good to add some new files required by
simulations of the VExpress_GEM5_V1 platform, namely:
a) The vmlinux files resulting from the compilations described here
=> http://gem5.org/ARM_Linux_Kernel#Linux_4.x
b) The DTBs from the compilations in the system/arm/dt directory of a
gem5 checkout
Does anybody see any inconvenient?
If there is a consensus on the upgrade, if you want I can provide a
Dockerfile with the necessary steps to build the new file (or if I
get the right permissions, I can upload the ~630MB file to the
gem5.org wiki and add a page explaining how it was generated).
Also, after these changes, we should also update "default_dtbs" and
"default_kernels" in FSConfig.py in order to look for the right DTB
and kernel for VExpress_GEM5_V1, and in turn, add some regression
tests for this new platform.
Thank you very much,
Pau
