Seems like 11th Gen Rocket Lake will not be supported

And then i checked on the intel website:

Don't you love it when the intel website conflicts with itself? Tiger Lake is almost half a year older than Rocket Lake.

[raldone01]

I could get my tiger lake to generate the pci interface (virtual functions) but in a windows guest the device fails with error 43.

Are you add hyper-v enlightenments?

[raldone01]

What do you mean? I have not done anything related to hyper-v.

[sieskei]

add in libvirt xml section feature

Or should I remove it completely?

Also are you use cpu host?

[raldone01]

Thank you! Do you mean this: <cpu mode="host-passthrough" check="none" migratable="on"/>

Do you know which intel drivers work for my windows guest? A link would be nice :upside_down_face:.

My config

[icanc0]

How did you even get virtual functions to show up? Have you also tested multiple VFs?

[raldone01]

sudo bash -c "echo 7 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs"
bash: line 1: echo: write error: Device or resource busy

Apparently windows is using it somewhat. Need to shutdown guest before I can change the number of VFs.

Woops I have a tiger lake: CPU: 11th Gen Intel i7-1165G7 (8) @ 4.700GHz I have read to many xxx lake identifiers today. GPU: Intel TigerLake-LP GT2 [Iris Xe Graphics]

[icanc0]

yea, as expected, the driver you loaded says tgl according to the logs.

[raldone01]

@sieskei Thank you its working!

[raldone01]

@sieskei Should I remove the QXL Display or the spice video card? @icanotc Sorry for hijacking your issue.

[sieskei]

@sieskei Thank you its working!

No problem, that’s good news! If you remove spice/virt gpu you will not have graphical output. Now you can try looking glass and virtual minitor to get better performance.

Btw how many virtual functions you set? Can you share your final libvirt xml?

[raldone01]

I set 1 VF but I can create up to 7. I have not tried to use more than 1 though.

My 'working' libvirt xml

```xml win11 87a95230-fd5d-4b48-9cab-60e63022a158 8388608 8388608 4 hvm destroy restart destroy /usr/bin/qemu-system-x86_64

I am currently writing a guide. It will eventually be available here.

@sieskei do you have a working setup? Does hibernation/suspension work for you?

[sieskei]

No, when I’m running with iGPU host and guest are super, super laggy. Mouse/Kbd are totaly freezing.

This is my ticket. https://github.com/strongtz/i915-sriov-dkms/issues/42

What is your distro?

[raldone01]

Ahh I already 👍 your issue. 🙃 Actually my host and guest are super laggy too but only when starting and when shutting down otherwise performance is OK.

I am using arch btw.

What distor/cpu do you use?

[sieskei]

I’m on Fedora 37 with kernel 6.1.14 and mesa 23.01.

Laptop is asus rog zephyros m16 2021. 11800H, 40Gb ram, gt1

[raldone01]

Did you use their intel-lts kernel or the dkms module?

[sieskei]

dkms module only, you?

[sieskei]

@raldone01 are you sure is working properly? I noticed that when iGPU is not use (task manager) does not laggy. When 3d rendering is needed then it freeze.

Usage is either 0 or 100. Can you check?

[raldone01]

The dkms module stopped working after a kernel update. (sound driver and i915 did not agree on something) So I now built intel-linux-lts myself. I have the same issue as you. Either 0 or 100 percent usage. Sometimes I get 20%. What program do you test it with?

[jubjubrsx]

I can verify that Rocketlake doesnt work, I pretty much get the same results on my MSI B560 with a 12 x 11th Gen Intel(R) Core(TM) i5-11600

the most infuriating part of this is that I tried a intel nuc at work that had a 11th gen in it (tiger lake) and it worked just fine.

[icanc0]

I actually asked on the intel forum, and the response is that 11th Gen desktop (Rocket Lake) is the only platform not supporting graphics splitting since 5th Gen Broadwell. I asked why, but the response was, "This is a top-level secret and we can't tell ya". They really want me to upgrade to a 12th gen huh?

I'm going to close this issue now, if the arc GPUs didn't disappoint me, this definitely did.
