Hi Jianjie Lin,

Thanks for these details!

Regarding graphics, the focus has been on GVT-d (so no sharing) after ACRN 1.0, and Tiger Lake does not support GVT-g. I’m not entirely up-to-date on the status of SRIOV for GPU, let me investigate a bit and get back to you.

The ivshmem (shared memory) mechanism to allow communication between User VMs does not break what I call strict isolation. But in your case, the fact you want to share graphics tells me you don’t really need strict isolation.

Regarding Functional Safety, is this a third VM that will run this FuSa workload? In the current state of affair, a FuSa VM would be run as a “pre-launched User VM”, the reason being that otherwise, you get the Service VM and ACRN Device Model that would need to be certified too, and that is not currently possible. A pre-launched User VM cannot share resources with other VMs so graphics sharing is not possible for that one for example. I’m also assuming this FuSa VM would not be running Linux.

Cheers,

Geoffroy

Hi Geoffory,

Thank you very much for your explanations.

About your questions:

* Do I need/want to share graphics between multiple VMs?

à Yes, I need to share the graphics between user VMS. As I seen from the acrn project, intel proposed the gvt-g solution. But I found tiger lake-based processor can not support the gvt-g, but only gvt-d, am I right?

By the way, does ACRN support the SR-IOV GPU virtualization, Like the AMD MxGPU?

* Do I need strict isolation between (some) VMs?

à Well, Actually, We would like to communicate with each VMS, is this “strict” isolation?

* Do I have realtime constraints (and are those “soft-realtime” or “hard realtime”)?

à in the current setting, real time is not important.

* How many Virtual Machines do you want to run?

à at least two User VMs.

* What host OSs do you want to run in those?

à my host OS is the Ubuntu 18.04

* Do parts of the system need to be certified for Functional Safety.

à yes, this is quietly important.

Thank you very much again for your reply.

Cheers,

Jianjie LIN

Hi Jianjie Lin,

This is correct, although a bit of a simplification. This is part of the evolution of Intel’s tick tock model [1], where new microprocessor architectures are introduced and the generation after is about a die shrink (new manufacturing process technology). That model evolved by adding an “optimization” step as well and this is what we are seeing here. So the short answer is, Whiskey Lake is *very* similar to Skylake, but not 100% identical. I don’t have a lot of experience running ACRN on Skylake but I do not know that graphics will be an issue if you need to do graphics sharing. I also believe that running ACRN on SKL should work if you don’t need the graphics sharing feature.

If you can tell me a bit more about your use-case (without disclosing any company confidential info), we can try to guide you the best we can. This is the kind of questions you should ask yourself:

* Do I need/want to share graphics between multiple VMs?

* Do I need strict isolation between (some) VMs?

* Do I have realtime constraints (and are those “soft-realtime” or “hard realtime”)?

* How many Virtual Machines do you want to run?

* What host OSs do you want to run in those?

* Do parts of the system need to be certified for Functional Safety

There may be more of those but that will already help us understand what you need!

Thanks,

Geoffroy

Hi Geoffroy,

As you said, a Skylake (SKL) system is not supported by ACRN hypervisor.

But I find “Whiskey Lake” in the supported Hardware list.

Based on the wiki:  https://en.wikipedia.org/wiki/Whiskey_Lake_(microprocessor)

“Whiskey Lake is Intel's codename for a family of third 14 nm generation Skylake low-power mobile processors. Intel announced Whiskey Lake on August 28, 2018”.

Am I wrong?

Since we are searching for a new hardware for our experiment, your opinions are important for our choice.

Thank you very much for your answer.

Cheers,

Jianjie Lin

Hi Jianjie Lin,

This is a Skylake (SKL) system, and unfortunately it is not tested (nor well supported). Do you have another system from this list that you can try it on? https://projectacrn.github.io/latest/reference/hardware.html#

I also saw your launch script in the Github issue (thanks for posting it), there is a problem with the GPU pass-through in it though as the PCI ID is not the one from the integrated GPU: https://pci-ids.ucw.cz/read/PC/8086/1539

Thanks,

Geoffroy

Hi Terry,

Thank you for your reply.

My system is stable and “dmesg |grep ACRN” also shows the correct message.

After I launch the guest Ubuntu in the acrn kernel, the acrn kernel (service VM) is directly reboot, and nothing happens (Here means the system just restart, and go the service VM again, but guest VM did not launch)

I follow the instruction in https://projectacrn.github.io/latest/getting-started/getting-started.html to install the ACRN hypervisor,

and follow the tutorial in https://projectacrn.github.io/latest/getting-started/roscube/roscube-gsg.html for installing the User VM, but without installing ROS environment.

Therefore the launch_ubuntu.sh is almost the same as in the  https://raw.githubusercontent.com/Adlink-ROS/ROScube_ACRN_guide/v2.1/scripts/launch_ubuntu_uos.sh

By the way,  I try the ACRN hypervisor in a dell pc with x86 cpu, I am not sure if this the NUC platform or not? Or Can we use an PC for deploying the ACRN hypervisor?

Thank you very much again for your help, and support.

Cheers,

Jianjie Lin

Hi Jianjie, welcome to ACRN world : )
For your reboot issue, first, you already successfully boot ACRN and Ubuntu SOS right, you can check dmesg as below. If you don't launch Guest VM, the system is stable right.

$ dmesg | grep ACRN

[    0.000000] Hypervisor detected: ACRN

[    0.862942] ACRN HVLog: acrn_hvlog_init

Then, you just run launch_ubuntu.sh to launch guest VM, could you login Ubuntu for first time or just reboot and never succeed ? BTW, which platform are you trying on, a NUC platform, e.g., NUC11 ?

There are two steps for next debug: 1. could you enclosed your 'launch_ubuntu.sh', we can check if anything missed. 2. enable serial port to get HV log for next analysis: https://projectacrn.github.io/latest/tutorials/using_serial_port.html

Hi Terry,

Thank you for your reply.

My system is stable and “dmesg |grep ACRN” also shows the correct message.

After I launch the guest Ubuntu in the acrn kernel, the acrn kernel (service VM) is directly reboot, and nothing happens (Here means the system just restart, and go the service VM again, but guest VM did not launch)

I follow the instruction in https://projectacrn.github.io/latest/getting-started/getting-started.html to install the ACRN hypervisor,

and follow the tutorial in https://projectacrn.github.io/latest/getting-started/roscube/roscube-gsg.html for installing the User VM, but without installing ROS environment.

Therefore the launch_ubuntu.sh is almost the same as in the  https://raw.githubusercontent.com/Adlink-ROS/ROScube_ACRN_guide/v2.1/scripts/launch_ubuntu_uos.sh

By the way,  I try the ACRN hypervisor in a dell pc with x86 cpu, I am not sure if this the NUC platform or not? Or Can we use an PC for deploying the ACRN hypervisor?

Thank you very much again for your help, and support.

Cheers,

Hi Jianjie, welcome to ACRN world : )
For your reboot issue, first, you already successfully boot ACRN and Ubuntu SOS right, you can check dmesg as below. If you don't launch Guest VM, the system is stable right.

$ dmesg | grep ACRN

[    0.000000] Hypervisor detected: ACRN

[    0.862942] ACRN HVLog: acrn_hvlog_init

Then, you just run launch_ubuntu.sh to launch guest VM, could you login Ubuntu for first time or just reboot and never succeed ? BTW, which platform are you trying on, a NUC platform, e.g., NUC11 ?

There are two steps for next debug: 1. could you enclosed your 'launch_ubuntu.sh', we can check if anything missed. 2. enable serial port to get HV log for next analysis: https://projectacrn.github.io/latest/tutorials/using_serial_port.html

Hi,

I am News to ACRN Hypervisor.   After installing the ACRN hypervisor and a Ubuntu user image according to the instruction from https://projectacrn.github.io/latest/getting-started/getting-started.html, I try to launch the ubuntu user in Ubuntu Service VM.
However, it will automatically reboot the system, without any error message.

Mein launch_ubuntu.sh is modified based on the launch_win.sh by changing the name of image file.

Thank you very much for your reply in advanced.
