Trying to bring up Android cuttlefish on my Jetson nano ; error = exiting with error 1: failed to create IRQ chip

[Marietto2008]

Hello Matt.

I'm trying an experiment that no one tried yet : trying to booting up Android cuttlefish on my Jetson nano 4 GB,where I have installed Ubuntu 22.04 and the kernel 4.9. At the beginning the default compiler was gcc 7.5 linaro. So the first thing that I did has been to upgrade it.

I've upgraded gcc on the jetson nano,following these tutorials :

https://huobur.medium.com/build-gcc-10-to-support-c-20-on-windows-10-raspberry-pi-and-jetson-nano-929f9439c143

https://askubuntu.com/questions/26498/how-to-choose-the-default-gcc-and-g-version

and now this is the version reported :

root@jetson:/home/aresuser/Scrivania/Android/android-image# gcc --version
gcc (GCC) 10.1.0

and then,based on this tutorial :

https://linaro.atlassian.net/wiki/spaces/QEMU/pages/29464068097/Run+Android+using+QEMU

This is what I did :

# sudo apt install -y git devscripts equivs config-package-dev  debhelper-compat golang curl
# git clone https://github.com/google/android-cuttlefish
# cd android-cuttlefish
# tools/buildutils/build_packages.sh
# sudo dpkg -i ./cuttlefish-base_*_*64.deb || sudo apt-get install -f
# sudo dpkg -i ./cuttlefish-user_*_*64.deb || sudo apt-get install -f
# sudo usermod -aG kvm,cvdnetwork,render $USER

and then :

I have no idea about what's broken. Someone can help ? thanks.

[madisongh]

I don't really know anything about this, but the "Address family not supported" errors might mean you need to modify your kernel configuration to add support for the VSOCK address family. Adding CONFIG_VHOST_VSOCK=y looks like it might help with that particular problem.

[Marietto2008]

Maybe you mean these entries ?

CONFIG_VHOST_NET=m
CONFIG_VHOST=m

they are set to m,so probably I can load these modules using this command :

modprobe vhost
modprobe vhost_net

right ? that's correct ?

[madisongh]

No, I meant VHOST_VSOCK

[Marietto2008]

Ok Matt,I have enabled VHOST_VSOCK in the kernel. This is what happens now :

Maybe because with the android emulator I have used gic-version=2 but not in Cuttlefish ? How can I define the gic-version in cuttlefish ? Which parameter should I use ?

Can I know if your patches include the KVM irqchip ? thanks.

[madisongh]

I don't use KVM myself, but a bunch of KVM-related patches were ported over, some time back. If you have CONFIG_KVM=y in your kernel config, that should turn everything on. There might be some additional patches needed from the linux-stable linux-4.9.y branch, though.
