Hi Musa,

 

There is no support for ARM-based processors at this stage. We would love to have this added to ACRN but nobody has stepped up to this task yet I’m afraid.

 

Thanks,

Geoffroy

Hello ACRN community,
Is there any support for ARM based processors? Or is there any such support planned?

Thanks!

Hi Geoffory,

In my case, ls /sys/bus/gpio/devices is empty

I use the tutorial here,

https://www.ics.com/blog/gpio-programming-using-sysfs-interface

https://unix.stackexchange.com/questions/485324/how-to-identify-gpio-pin-numbers-is-gpio-driver-loaded

But it did not work out for me

Thanks,

Jianjie Lin

Hi Jianjie,

There isn’t much useful info in the log that you attached in your previous email. Can you expand a bit on how you have tried to use this? Do you see the any GPIO controller (e.g.: ls /sys/bus/gpio/devices)

Thanks,

Geoffroy

Hi Fuzhong,

Thank you very much for your reply.

In cannot see gpio pins in sor and HV?

I tried with serval methods, but apparently, it did not work out. We try to use this gpio pin to control the motor as an automotive application.

I attached the boot log.

If you need to any information about the whiskey lake, I am pleasure to offer those information.

Thank you .

Hi Jianjie

Not see the gpio pins in sos or HV? 

Could you please share full HV boot log about your issue?

Thanks!

Hi Jianjie,

I do not have any experience with the GPIO subsystem I’m afraid, @Xie, Nanlin, can you ask someone on the engineering team to help look at this?

Thanks,

Hi Acrn community,

After we successfully deployed the acrn hypervisor in the whiskey board 10, we found we could not see the gpio pins inside the acrn hypervisor, which apparently should be included.

Do you know the reason?

Thank you

Hi Geoffory,

I cannot promise you that our group can contribute on this topic. But our group is interesting in to find a way how can we make it properly to use libvirt for the configuration.

Cheers

Jianjie Lin,

Hi Jianjie,

This is something we have been thinking about, i.e. using libvirt as the primary mechanism to handle the ACRN post-launched VM lifecycles. We will have to make sure we can implement all options via this libvirt interface but at some point it should be possible to replace the launch scripts.

Note that it wouldn’t replace acrn-dm per se, the Device Model will still exist but it will be called directly by libvirt.

I don’t believe we have a timeline for that though. Is this something you’d be interested to contribute to?

Thanks,

Geoffroy

Hi acrn community,

As the new release version of 2.6, I find an interesting tutorial about Configure ACRN Using OpenStack and Libvirt  https://projectacrn.github.io/latest/tutorials/setup_openstack_libvirt.html

Therefore, I would like to ask, if it is possible to replace the launch file, which contains the ARCN device model, with the standard libvirt approach?

Do you have any suggestions?

Thank you.

Cheers,

Jianjie Lin

Hi Geoffroy,

Thank you for your reply.

We would like to use CI tools to start UserVM in background and then run some tests there.  

Thank you and best regards,

Feng

Hi Feng,

There is no option to provide the user name and credentials for the User VM OS in the launch script. However, I believe there are ways to set-up the OS to auto-login for a specific user. But can you tell me a bit more about what you want to achieve? I’m wondering why you would want to be automatically logged in?

I have not played with this yet but I think you should be able to modify the “-s 5,virtio-console,@stdio:stdio_port” line in your launch script to redirect this elsewhere (e.g. PTY) – see also https://projectacrn.github.io/latest/developer-guides/hld/virtio-console.html

Thanks,

Geoffroy

Hello all,

In the service VM, we launch an User VM with its launch file. In the console version, the standard way is that we need to use the user name and password to log in the system.

Is there any other option to directly write these information (user name and password ) inside the launch file, so that no additional manual step is required. Or How can we put the program in the background, and use the same terminal for launching the second User VM.

Thank you for support in advance.

Best regards,

Feng
