Yes, that’s the driver in question. I do not know if we have a version of it for the latest kernel, let’s see what the kernel team has to say about it. Geoffroy

I don’t see this anywhere in the 5.10 version, while it was there in the 4.19/preempt-rt. I suspect that means it’s a driver that was never upstreamed (or is still in the process of being upstreamed).

I’d love to see that being added to our code, would you care to develop and patch and submit it upstream? 😉 Thanks! Geoffroy

I do not believe this is possible although this may be an interesting feature. What use-case do you have in mind for this? Geoffroy

Glad you were able to fix it! Can you tell me what fixed it? I'm specifically interested in there are things we need to update/improve/modify in our documentation. Thanks!

Can you tell me how you installed the RT kernel inside the VM? Do you have a serial port on your system running ACRN? If so, I would like to see the output from there.

Are you using the same launch script when you can successfully launch the standard User VM?

Does that mean this system is completely unusable now? Have you tried physically pulling the power cable from the device and waiting at least a few seconds before plugging it back in? I'm not sure how

True, and the longer answer is (and I will also invite all the engineers and architects to correct me if and where needed): you don’t need those because the Service VM is not involved in the schedulin

Could you be hitting something similar as this: https://github.com/projectacrn/acrn-hypervisor/issues/5811 Can you try to boot with with “uart=disabled” and see what happens? Add this to your /etc/gru

Can you share more details about your set-up? More specifically: - Hardware platform (inc. lspci output) - ACRN version - Launch script Thanks, Geoffroy

Hi Christoph, I’m not an expert on kernel BUGs either, but it does look indeed like it’s related to XRDP (it’s mentioned in the trace so your observation seems very correct). Could you try to run the

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

It seems like the basic GPIO controller is not even detected, which can be caused by a driver that’s missing. Have you ever been able to use the GPIO interface on that board using a native Linux (no A

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/

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 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

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 op
