Hi Jianjie ACRN v2.0 support GVT-g and GVT-d. https://projectacrn.github.io/2.0/tutorials/using_ubuntu_as_sos.html base on GVt-g and https://projectacrn.github.io/2.0/getting-started/rt_industry_ubuntu.html base on GVT-d
That is why you found the big difference between them.
For GVt-g: 1) Connect two monitors to your board; and set Aperture Size to 512(Chipset--->Graphics Configuration--->Aperture Size) in the BIOS settings 2) Please refer https://projectacrn.github.io/2.0/tutorials/using_ubuntu_as_sos.html#install-the-service-vm-kernel Adding following kernel cmdline in /etc/grub.d/40_custom; then sudo update-grub
i915.nuclear_pageflip=1 i915.avail_planes_per_pipe=0x01010F i915.domain_plane_owners=0x011111110000 i915.enable_gvt=1 i915.enable_guc=0
3)Remove --windows \ in your launch script(gpu_launch_uos2) since you will launch ubuntu user VM, not Windows VM.
If GVT-g still doesn’t work on your side, please connect UART cable to COM1 of WHL, then input “vcpu_list“ after ACRN:\> prompt; and share us the log.

Hi Terry， Thank you for your reply. SOS: https://projectacrn.github.io/2.0/tutorials/using_ubuntu_as_sos.html i915.nuclear_pageflip=1 i915.avail_planes_per_pipe=0x01010F i915.domain_plane_owners=0x011111110000 i915.enable_gvt=1 i915.enable_guc=0
è I put the kernel cmdline in the /etc/grud.d/40_custom I found the https://projectacrn.github.io/2.0/tutorials/using_ubuntu_as_sos.html has a big difference compared to https://projectacrn.github.io/2.0/getting-started/rt_industry_ubuntu.html, which I follows to install the acrn hypervisor and acrn kernel.

è I put this cmdline with –B “ ” à did not work out è I put this cmdline in the Ubuntu guest /etc/default/grud of linux command default line à it did not work out
$sudo mount /dev/sda1 /mnt
$ sudo sed -i "s/0x01010F/0x010101/" /mnt/loader/entries/acrn.conf
$ sudo sed -i "s/0x011111110000/0x011100001111/" /mnt/loader/entries/acrn.conf
$ sed -i 3"s/$/ i915.enable_conformance_check=0/" /mnt/loader/entries/acrn.conf
$ sudo sync && sudo umount /mnt && reboot
à I can not find this file mnt/loader/entries/acrn.conf, do you know why?
In a short summary, after I tried those cmdline, it did not really solve the problem. The terminal still stuck in the line of Unhandled ps2 mouse command 0x88. Do you have any further suggestion?
Cheers Jianjie Lin

Hi Jianjie, Yes for v2.5 release, the default config is gvt-d. If you really want to try gvt-g, switch back to v2.0 release branch please. Remember switch GSG document to v:2.0 also, there are setting guide for gvt-g, especially kernel command line below:

Hi ACRN-community,
Our team faces the problem of the GPU-d/g for a long time. We try all the possibilities according to the resource from the tutorial or GitHub; however, the issue remains. According to the tutorial, we use a whiskey lake i7 board for the gpu sharing or pass-through, which is fully supported by the acrn hypervisor.
We have tried release v2.5 as the starting point. We can successfully launch the uos in the console version, but the GPU version is either automatically rebooted or stuck for an hour without further action. Then we return back the v2.0 since, based on the issue report, the gvt-g is a known issue since the v2.1. However, it still does not help after we install the release version 2.0.
I attach three files for your diagnose
Thank you very much for your support. Looking forward for your reply.
Mit freundlichen Grüßen / Kind regards Jianjie Lin
