Succeded with intel-i915-dkms bakckport for LTS61 on 11800h laptop, host suspends and wakes perfectly! #101

right-0903 · 2023-08-17T08:20:29Z

I have tried with the dkms module from the repositroy(with 6.1.44-MANJARO or 6.4.10-zen2), and I also tried to build this 6.1.38 from linux-intel-lts with this aur package. None of them work with my instance.

Then I found the backport driver ocassionally. You will get the introduction about backport here, aka the out-of-tree driver. And you will find more functions about sriov in backport driver compared with linux-intel-lts, that is no wonder why backport driver work for 11800h while linux-intel-lts not.

you can install the dkms module similarly, make sure you are 515LTS kernel as backport required, I just tested with it. If you are ubuntu, suse, or redhat refer this. There is a packaged dkms module.

Today(10/07/2023), I have packaged for backports driver, you can easily install on arch, refer this

The source doesn't contain a dkms configuration file, you should create one, I list below(I built the debian package in my cloud instance, which contains this.), actually you can download it from intel's repository accroding to this.

The following is my configuration.

Test Environment:

host info:

OS: Manjaro Linux x86_64
Kernel: 5.15.125-1-MANJARO 
CPU: 11th Gen Intel i7-11800H (16) @ 4.600GHz
GPU: Intel TigerLake-H GT1 [UHD Graphics]
GRUB_CMDLINE_LINUX="intel_iommu=on iommu=pt i915.modeset=1 i915.enable_guc=3 i915.max_vfs=7 i915.reset=1 vfio-pci.enable_sriov=1 split_lock_detect=off" (I think not all parms. are necessary)

virsh or qemu configuration

I got it from archwiki, maybe unnecessary.

    <hyperv mode="custom">
      ...
      <vendor_id state="on" value="GenuineIntel"/>
      ...
    </hyperv>

make sure you don't hidden virtualization, credit to @pagkly . I think the guest driver need a flag to know itself is a VF. Hiding kvm is allowed in my case.

⚠️ Warning: do not use!

    <feature policy="disable" name="hypervisor"/>

guest info:

Driver suggestion: 4577 or the latest, some guides recommend 3222, it doesn't work for me.

Guest 1	backport kenel driver	driver from intel-lts or this repository
3222 or 3111	code43	0% utilization
4577	works	code43

guest 1

Edition: Windows 10 LTSC

Guest driver: 4577

guest 2

All my VMs work now with 4577.

Result

Working normally here with intel-i915-dkms bakckport for LTS515 on my 11800h laptop.

Here is the intel_gpu_top -d sriov output under headless.

Suspend

About suspend, the guest will not sleep I think, after I wake host up, I reconnect my guest, there is no relogin animation, and I can't access sleep info by powercfg /sleepstudy. In the host,

EDIT:

revise grub confg update, I mess them up, sudo grub-mkconfig -> sudo update-grub, or use sudo grub-mkconfig -o /boot/grub/grub.cfg.
append several kernel commandline parm.s: intel_iommu=on iommu=pt i915.modeset=1, I notice not all people use them, but necessary.
add several guest instances, and remove version requirement(21h2+), add credits.
add an aur repository for this backports package.

Hi, my distro is Arch and backport successfully built with 5.19 kernel. I could not get dkms to install on 5.15. However, once I reboot, GDM could not load. It shows black screen with blinking underscore.

You mean you can't install dkms or i915 dkms module with 5.15. Have you read dkms log? Is Ctrl+Alt+F2-7 available? have you looked into journal such as journalctl -rb -1? BTW, I use sddm-git which is running on Wayland, X11 or Wayland login session work. At last, why don't you try to install Manjaro Linux515 and headers packages ? you can download and install easily as I download linux-zen from the arch official repository.

Cannot build i915 backport dkms module on kernel 5.15, due to error but I can install it on 5.19.13-arch1-1.
I tried switching to sddm-git but still cant load sddm it says Error Internal "Process crashed" when I looked into journalctl -rb -1

I can't find a prebuilt linux515 or linux519 for arch linux, so I can't test for you, can you show me dkms build error log on 515? Make sure your subversion is not too old, mine is 5.15.125, you can also access the prebuilt linux515-5.15.125-1-x86_64.pkg.tar.zst linux515-headers-5.15.125-1-x86_64.pkg.tar.zst from manjaro mirror, such as here.

do some changes, make it built on 6.1, then I get a underscore too, that means i915 don't work, but my Nvidia works when I attach another monitor to it. log tell me there are some unknown symbol, one of the reasons is svm, I commented svm when building, because thera are some changes to vma, svm code use it. But I am not familiar with it and I can't find any commit about i915 svm in mainline.

I tried following your setup on Manjaro 5.15.125 but could not get sr-iov to work.
When I tried to set VF, it says Numerical result out of range.
Might be because I have Iris Xe GPU. My CPU is i5 1135G7.

have you set kernel command line? what is the kernel buffer? This issue is related to max_vfs setting which is logged in kernel buffer

you can modinfo i915 to determine the working driver, which will display driver path and dependencies, one of dependencies is compat. BTW, if you have set early kms or some other things, make sure you have regenerated initramfs.

Yours is too old, the driver out of tree is more recent than mainline. And the firmware that the module loaded is compatible downwardly, I don't want to explain here, you can read i915 source code. Apparently, your module can't load firmware, download firmware for tgl in the link I mentioned or log mentioned, and place them to /lib/firmware. just read log carefully, dude.

code43 is really weird. my suggestion is try to add some quirks like vendor Id, use MS stock image with the latest update installed, remove virtual display like qxl, connect to it with RDP. And you can also use 3222 or 3111, it chances, good luck.
BTW, use rapr to clean graphics driver when you are trying new driver, I would clean all components came with it, like audio and so on. clean install offered by intel is garbage.

I managed to use looking glass with iddsampledriver: https://github.com/ge9/IddSampleDriver
Everything works fine except minecraft bedrock

also I had another screen in addition to the one I specified in the driver option.txt and I had to tell windows to only display on one of them to fix mouse position and have graphic acceleration

gen 11 works perfect using this "intel-i915-dkms bakckport ", while in gen 12(i3-12100, uhd730) I always get code 43 in vm.

many reasons cause code 43, like hiding virtualization, improper driver, etc. You should submit more information. BTW, i915 backport have support linux 6.0lts officially, you can also report this to Intel.

Did you try to pass to romfile qemu/libvirt parameter IntelGopDriver.efi from your motherboard's BIOS? For me it had solved the issue.

Hello, all!
Just now, I find time for it and I managed to compile it for LTS 6.2.
I'm trying it with Win11, and I think it's working, but I'm having trouble launching the Looking Glass host.
I created a virtual monitor with IDDM.
What are the settings in your Looking Glass INI file?

You can create a qxl display to check, I don't set specific settings. BTW, 6.2 is not LTS, even though 6.2 is supported officially now.

You're not using the Xe driver but i915 (as that's still the default) you must use xe.force_probe to use Xe driver, like: i915.force_probe=!56a2 xe.force_probe=56a2 where 56a2 is your GPU's model ID from lspci -nn.

I did try, good luck getting even a desktop running. Long way to go.

rba-andrade · 2024-02-22T20:06:41Z

I did use the force probe, I can get desktop running, but no sucess with SR-IOV. You need to compile mesa with meson build option "-Dintel-xe-kmd=enabled" so you can get to desktop.

plantroon · 2024-02-22T20:10:15Z

I built mesa-git with that build option and it only showed me rainbows or psychedelic imagery in all sddm, gdm, hyprland and gnome session. Is a specific version of mesa needed?

rba-andrade · 2024-02-22T20:12:19Z

I use mesa 24.0.1, but in theory if you are using mesa-git you don't need this option anymore. It has been removed from mesa-git and should work without it. I use hyprland and greetd+gtkgreet for login manager. Will try with mesa-git and give you feedback.

plantroon · 2024-02-24T18:59:47Z

Tried mesa 24.0.1 as well. In both cases I get errors like in the photoscreenshot.

😔

What is your hardware? I have i5 1235U with Iris Xe graphics

rba-andrade · 2024-02-28T19:48:23Z

Didn't work for me with mesa-git, but mesa 24.0.1 works. I'm using an i7-1165G7 with Iris Xe graphics. Did you include CONFIG_DRM_XE_DISPLAY=y in yours kernel config?

plantroon · 2024-02-28T20:32:46Z

Yes CONFIG_DRM_XE_DISPLAY=y was configured. How did mesa-git behave on your side?

EDIT: mesa 24.0.1 works. Colors seem off but at least they're not all inverted. That's on Gnome shell. Hyprland(/-git) no luck ;(

yes, I gave it a try, after did some changes, it can be built, then boot into desktop, throw dereference null ptr error, and drm issue, screen freezing. nowadays, it's a mess, they backported drm module, added dmabuf module, give several build option i915, i915_only, drm, dmabuf, nodrm and so on, but I don't find a doc about how to really do it. I set build all modules, but it wouldn't.

It only boots with "ibt=off" kernel parameter because of MISSING ENDBR instructions. Is there any changes to compile parameters that makes it work?

Hi chiming in, am total newbie just wanna ask some questions (sorry for clutter) Can sr-iov work out of the box now for example on debian unstable which has kernel 6.8 (has the new xe driver which supposedly has it sriov built in?) and mesa 24.1.1? if no then what components are still missing? Also do you need anything other than virtualization enabled in bios? I have a basic locked down bios on a 12th gen laptop (i5-1235U)

johntdavis84 · 2024-06-25T20:34:34Z

Hello, These are great questions. :) There’s another GitHub where the work is being done to get this into the mainline Linux kernel, but I’m not sure which repo that is. SR-IOV features with the i915 requires this DKMS driver (or the one from Intel’s repo—I’m not sure which one is further along in development right now) be manually installed and maintained. SR-IOV will not work out of the box with the Linux kernel until the replacement for the i915 driver (the upcoming “Xe” driver) replaces the i915 driver as the default, which is likely not to happen until, I believe, kernel 6.11, which might be released in October, and will then need to filter down to distro releases. It’s a little confusing because the Xe driver is a huge change, and they’ve been implementing a lot of the underpinning infrastructure since at least 6.8. Xe will appear as a non-default replacement for i915 before it becomes the default, most likely. Keep in mind that when SR-IOV hits mainline, you won’t need this DKMS or have to do any of this, but that won’t be until at least October. If your BIOS lets you enable virtualization enough for, e.g., Proxmox to work, you should be fine. Some BIOSes have a separate option to enable SR-IOV or VTd, but if your BIOS doesn’t have those, assume they were automatically turned on when you enabled virtualization, unless you’re having issues. One thing you absolutely need to do if you can is disable secure boot. It makes this all more difficult and unpredictable. There are some tutorials that show you how to verify you have your BIOS settings correct. The first two links assume you're running proxmox, but the under the hood setup and verification of the BIOS settings are the same for any Debian/Ubuntu. https://pve.proxmox.com/wiki/PCI(e)_Passthrough https://pve.proxmox.com/wiki/PCI_Passthrough https://www.derekseaman.com/2023/11/proxmox-ve-8-1-windows-11-vgpu-vt-d-passthrough-with-intel-alder-lake.html Proxmox VE 8.2: Windows 11 vGPU (VT-d) Passthrough with Intel Alder Lake - derekseaman.com - J.
