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 .

Best,

Jianjie Lin

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,

Geoffroy

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

Best,

Jianjie Lin

Hi Jianjie,

This is good to know! We will keep that in mind, it will be good to have extra eyes looking at this when we develop this.

Thanks,

Geoffroy

Hi Feng,

I am not well versed on CI tools and how they work. Our CI team is in China, and hence on holiday this week.

Do you have full control of your test image? If so, you could build it so that it does not ask for a password, and/or run the tests automatically (via a system service file for example).

Thanks,

Geoffroy

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

Hi all, 

We are very pleased to announce Version 2.6 release of ACRN. You can see the release blog from https://projectacrn.org/blog/ and detailed Release Notes in website https://projectacrn.github.io/latest/release_notes/release_notes_2.6.html

What’s New in v2.6

·       Nested Virtualization Technology Performance Tuning:

The performance of nested virtualization, a feature first introduced as a preview in the v2.5 release, was improved. CPU and I/O performance of level 2 virtual machines (for example, a VM running on a KVM/QEMU VM that itself is a VM on ACRN hypervisor) is now on par with a VM running on KVM on bare metal. Read more in the Enable Nested Virtualization tutorial.

·       Support loading OSs in ELF format:

ACRN hypervisor now can load OS images packed in ELF (Executable and Linkable Format). This adds flexibility to OSs such as Zephyr running in pre-launched VMs.

·       Document Updates:

We’ve made major improvements to the introductory ACRN documentation including:

²  What Is ACRN

²  Configuration and Development Overview

²  Getting Started Guide

²  Introduction to ACRN Configuration

We’ve also made edits throughout the documentation to improve clarity, formatting, and presentation:

²  Device Model High-Level Design

²  ACRN High-Level Design Overview

²  Power Management High-Level Design

²  Virtio Devices High-Level Design

²  I/O Emulation High-Level Design

²  Virtio-Net

²  Enable ACRN Over QEMU/KVM

²  Enable CPU Sharing in ACRN

²  Enable Nested Virtualization

²  Configure ACRN Using OpenStack and Libvirt

²  Getting Started Guide for ACRN Hybrid Mode

²  ACRN Documentation Generation

See the v2.6 full release notes and documentation for more information about this release including fixed and known issues.

Upgrading to v2.6 From Previous Releases

All project ACRN source code is maintained in the https://github.com/projectacrn/acrn-hypervisor repository and includes folders for the ACRN hypervisor, the ACRN device model, tools, and documentation. You can download this source code either as a zip or tar.gz file (see the ACRN v2.6 GitHub release page) or use Git clone and checkout commands:

git clone https://github.com/projectacrn/acrn-hypervisor

cd acrn-hypervisor

git checkout v2.6

The project’s online technical documentation is also tagged to correspond with a specific release: generated v2.6 documents can be found at https://projectacrn.github.io/2.6/. Documentation for the latest development branch is found at https://projectacrn.github.io/latest/.

ACRN v2.6 requires Ubuntu 18.04. Follow the instructions in the Getting Started Guide to get started with ACRN.

Best & Regards

Terry

Hi Jianjie,

You are right, there is acrn-unit-test repo in acrn github. We ported from kvm-ut and adapted to ACRN arch 3 years ago, you can find detailed commit in: https://github.com/projectacrn/acrn-unit-test/commits/master/guest

But now it is still test framework ready only, no much detailed test case yet. If you are interested, welcome to discuss and joint-contribution together : )

We can update the setup steps in https://github.com/projectacrn/acrn-unit-test/blob/master/README later, then you may try it on ACRN codebase. Stay tuned please.

Best & Regards

Terry

Hi acrn community,

I find in your GitHub repository, there has acrn-unit-test

https://github.com/projectacrn/acrn-unit-test 

It is quite interesting for me. But I find this repository is quite old.

Therefore, I would like to ask do you have any new acrn-unit test program, and how do you test for example, the property of free from interference (FFI).  

Thank you very much for your response.

Cheers

Jianjie Lin

Minor corrections for below :

1. vRTCT is in SOS or Hypervisor ?

         A: For Pre-launched VM, RTCT is pass-through, for post-launched, vRTCT is built in SOS/DM.

1. Does Software SRAM support L3 cache?

      A: Yes, both L2 and L3 are supported for Post-launched RTVM and Only L3 is supported in ACRN on platform that Software SRAM is supported.  

Thanks.
