Add arm64 support

[hwittenborn]

This was mentioned a bit in #12, but I have a need for arm64 variants of the images for use in my application.

I thought about maintaining this in a separate fork, but it looks like FlatImage requires several external repositories as part of it's build process, which would make this a bit infeasible as a fork long-term. arm64 is also a fairly popular architecture (e.g. Flathub and Snap support it), and I think it'd be nice to have it for any people who'd want it.

Tracking status for arm64 support in FlatImage's dependencies:

• https://github.com/ruanformigoni/e2fsprogs (Add arm64 support e2fsprogs#1)
• • https://github.com/ruanformigoni/libfuse (Add arm64 support libfuse#1)
• https://github.com/ruanformigoni/proot (Add arm64 support proot-static-musl#1)
• https://github.com/ruanformigoni/bubblewrap-musl-static (Add arm64 support bubblewrap-musl-static#1)
• https://github.com/mhx/dwarfs
• https://github.com/ruanformigoni/bash-static (Add arm64 support bash-static-musl#1)

Hi @hwittenborn , thanks for the issue. Supporting arm seems feasible, I'll start to look into it.

[hwittenborn]

Thanks @ruanformigoni! I don't know what your open time to work on FlatImage looks like, but if you'd like I could go ahead and help out with getting PRs going on the needed repositories.

[ruanformigoni]

Sure, feel free to do so. Thanks again!

[hwittenborn]

On another note, would you be open to making an organization for FlatImage @ruanformigoni? Even if you're the only person in it, I think it'd be quite beneficial to see where all of FlatImage's external dependencies are. Most of the repositories I listed above were found through digging, but if they were all under a single account it'd be much easier to see what's being used where at a glance.

[hwittenborn]

It was mentioned in ruanformigoni/libfuse#1, but all PRs have available releases in their respective repositories testing the changes. Feel free to hold off on merging any of them until all the PRs are set up, tested and ready to go though.

[hwittenborn]

All of the PRs should be pretty much ready to go @ruanformigoni, but there doesn't seem to be a super easy way to get QEMU going on GitLab CI at first glance.

This is tying back to #12 a little bit, but if the releases could be published here on GitHub then I could pretty easily get a CI job going to publish all of the needed images on both amd64 and arm64. If you're against that idea I can look more into getting it going on GitLab, but I'd definitely prefer to do it on GitHub where I'm more comfortable if you're open to it.

[ruanformigoni]

Nice! Thanks, I'm merging the PRs. I usually don't work on github because I prefer open source alternatives if they exist, also the possibility of self-hosting gitlab is pretty neat. An alternative to #12 could be to create a github release with the gitlab runner as you said in #15, with the same artifact links or novel packages uploaded to github. However, if it is not possible to create arm64 binaries on gitlab then I'd have no problem to use this as the main repository. I'll look into the organization.

[hwittenborn]

Hey @ruanformigoni, I just wanted to say I'm still working on getting arm64 support working in FlatImage itself. I'm currently working on that all in https://github.com/hwittenborn/flatimage where I'm getting it all working via a GitHub Action workflow, but a fair bit is still broken and I'm not quite sure when that'll be completed yet.

[ruanformigoni]

Thanks for that! I'll set up an aarch64 machine to try things out as well.

[p2pdownsbrz]

@ruanformigoni , How is the progress of the arm64 version?
Is arm32 possible too? I'm studying your project, I really liked it. I have a armv7l linux device. I intend to do several tests with your project on this arm device. What cpu architectures will you officially support?

[ruanformigoni]

Hi @p2pdownsbrz ! Thanks for your interest in the project, it is possible but currently it only supports x86_64.

[Azathothas]

@ruanformigoni Hi,

I am trying to build it on arm, It is successfull, partially (It hangs as shown in the pic) but there are some hard-coded things that need to be changed:

• ./src/cpp/lib/bwrap.hpp

#This needs to be extended to account for aarch64
+ f_find_and_bind("/usr/lib/aarch64-linux-gnu", "nvidia", "cuda", "nvcuvid", "nvoptix");
  f_find_and_bind("/usr/lib/x86_64-linux-gnu", "nvidia", "cuda", "nvcuvid", "nvoptix");
  f_find_and_bind("/usr/lib/i386-linux-gnu", "nvidia", "cuda", "nvcuvid", "nvoptix");

• ./src/boot/config/config.hpp

- ns_env::prepend("LD_LIBRARY_PATH", "/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu:");
+ ns_env::prepend("LD_LIBRARY_PATH", "/usr/lib/aarch64-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu:");

I don't know if that's all that is needed to enable aarch64 support, so I apologize if that isn't the case and it's not as simple as it seems.
Thanks!

Edit:
After waiting for 30-50 seconds, it does actually work:

$ file /tmp/FLATIMAGES/blueprint.flatimage

[ruanformigoni]

Hi @Azathothas, that is really cool! Thanks for taking the time to dig on this, you can have a better idea of what is causing the slowdows by enabling debug mode with FIM_DEBUG=1 /tmp/FLATIMAGES/blueprint.flatimage.

[Azathothas]

Hi, yes, seems like it's my own static binary that's breaking it.

So it is the dwarfs binary....?
I am using the dwarfs binary from: https://github.com/mhx/dwarfs/releases/download/v0.10.1/dwarfs-universal-0.10.1-Linux-aarch64-clang

[ruanformigoni]

I am using a custom build of dwarfs to support the imagesize option, here is my fork where I build the releases, and here is the branch in which mhx implemented this option and here is the related issue. The delay you see is a timeout of 60 seconds for the fuse filesystems to mount, when that fails, it proceeds to enter the container without them.

[Azathothas]

Thank you for pointing me in the right direction.
Seems like, I will only have to make changes to https://github.com/ruanformigoni/dwarfs/blob/experimental/image-size/build.sh
And it should work....
I will try and update you on my progress

[Azathothas]

Hi @ruanformigoni , I have finally done it.

pushd "$(mktemp -d)" >/dev/null 2>&1
git clone --filter="blob:none" --depth="1" --quiet "https://github.com/Azathothas/flatimage" && cd "./flatimage"
chmod +x "./deploy/flatimage.sh"

sudo "./deploy/flatimage.sh" blueprint
rsync -achLv --mkpath "./build/dist/." "/tmp/FLATIMAGES"
find "/tmp/FLATIMAGES" -type f | xargs -I {} sh -c 'file {}; sha256sum {}; du -sh {}'

FIM_DEBUG=1 "/tmp/FLATIMAGES/blueprint.flatimage"

It booted up instantly, however I am still seeing some errors, are these harmless?

Great work!

These happen because the desktop integration was not configured, so it is ignored.

E::desktop.hpp::336::Could not parse json data: Failed to parse json data: ''
E::log.hpp::192::Could not parse json data: Failed to parse json data: ''

The FIM_VERSION errors happen probably because you haven't pulled the git tags when you cloned the repository, so the FIM_VERSION variable is not set, which does not break anything useful besides version checks.

I will update the work that @hwittenborn has done to create aarch64 and aarch32 binaries for the binaries pulled by the flatimage.sh build script, dwarfs inclusive.
