为啥没有权限....

看dmesg的输出，你的核显不支持SR-IOV，应该尝试GVT-g。

Hey, it's amazing that you have brought it so far!

I've the following problem. When I try to bind one of the VFs (02.1) to the VM (Win 11) the iGPU does not seem to work (Code 43 in the device manager)

I'm running a 12600k on 6.11.5.

VFs are created and visible in device overview.

02.1 is bound to vfio at boot.

Any idea why it's not working?

Your Rocketlake is not supported SR-IOV, please try GVT-g instead.

GVT-g not supported with INTEL-GVT-G plug in, i have an i5 11600K

不是啊,我的是i5 11400 GVt-g不支持的😂,昨晚弄了好久设备那里就是不显示

根据intel的支持文档，https://www.intel.com/content/www/us/en/products/sku/212270/intel-core-i511400-processor-12m-cache-up-to-4-40-ghz/specifications.html?wapkw=11400

i5-11400就是只支持GVT-g，https://www.intel.com/content/www/us/en/support/articles/000093216/graphics.html 。

只能等gvt-g的驱动更新了。

According Intel's documents, i5-11600K is RocketLake which only supports gvt-g. Could ask the updating for intel-gvt-g plugin.

There is also this article. So it looks like Rocket Lake does not have any support.

Summary

Information about the support of GVT-g technology on 11th Generation Intel® Processors.

Description

Unable to find information regarding the support of GVT-g technology on 11th Generation Intel® Processors.

Resolution

NoteSR-IOV (Single Root IO Virtualization) is supported only on platforms with 11th Generation Intel® Core™ "G" Processors (products formerly known as Tiger Lake) or newer.

GVT-g technology is not supported.

The 11th Generation of Intel® Core Processors works with SR-IOV (Single Root IO Virtualization), that is a new virtualization feature supported in hardware starting from Intel® Iris® Xe and in some of our discrete cards.

Gen9 (i.e. Graphics powering 6th through 9th generation Intel processors) is the last generation of the software-based vGPU solution GVT-G (Intel® Graphics Virtualization Technology –g).

So the 11th generation Rocket Lake cpu does not support GVT-G nor SR-IOV... This is incomprehensible😑

Will this method (usage of plugin) make it possible to get video on a physical screen directly attached to the laptop?

I can attach a SR-IOV graphical adapter 02.1 to the VM, but other than a VNC (or other IP based remote screen viewer) I get no screen output on the laptop's screen, or to a HDMI output directly from/on the host.

"XML error: Invalid PCI address 0000:06:10.0. slot must be <= 0"
這個錯誤提示我也有可以直接改XML
1. 先選0的, 保存
2. 編輯XML , 將0x0 改成1~7都行, 保存

然後進入windows後需要安裝驅動, 否則裝置無法識別

Hey, it's amazing that you have brought it so far!

I've the following problem. When I try to bind one of the VFs (02.1) to the VM (Win 11) the iGPU does not seem to work (Code 43 in the device manager)

I'm running a 12600k on 6.11.5.

VFs are created and visible in device overview.

02.1 is bound to vfio at boot.

Any idea why it's not working?

Yay I finally got it working!!!

Tried everything: Reinstalling the plugin, intel_gpu_top, using the modified kernel instead of the addon...

But the error 43 always remained.

The solution was the following:

Although I already had the intel GPU driver installed, I had to reinstall it with the option for "clean install" marked (otherwise it didnt't work). After the reinstall everything worked as a charm

I'm finally able to run my Win11 VM on VF 2.1 with Parsec (using the Virtual Display Driver) (don't forget to remove the Red Hat Display Driver)

does anyone have transcoding issues with Plex, when enabled the VFs?

I just fix this issue in unRaid 6.11.5, remove /boot/config/plugins/i915-sriov/5.19.17 and reboot will update the module

I installed the plugin earlier this week, just before is appeared on CA

Since then, my Plex and Fileflows containers can't use quicksync anymore, any flows that need transcoding are failing with:

[WARN] -> Cant process '/usr/local/bin/ffmpeg -loglevel error -f lavfi -i color=black:s=1080x1080 -vframes 1 -an -c:v hevc_nvenc -f null -': [hevc_nvenc @ 0x55702636efc0] Cannot load libcuda.so.1

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

And Plex is now hammering my CPU directly for any HW transcode streams.

Is there anything I need to change in the params or individual configs for plex/fileflows so they're using the correct device(s)?

They both currently have --device=/dev/dri in the extra params which was working before I split out the device.

(I'm on an i5-12600K)

*EDIT* - Just saw the post about someone with the plex issue and they 6.11.5 fix. I'll try it this evening and see if it fixed file flows as well. Would it be worth swapping to the CA version, or do they pull from the same place? I did update it a couple of days ago but not sure if they're in sync or not.

i just reeinstalled the plugin, since i went back to stock to check if the problem comes from sriov.

Thanks for working on this plugin! Was just asking the Unraid Discord about this issue a few weeks ago...

I've followed all of the steps and believe that I have the plugin working as intended, but I think my motherboard is causing it not to be usable for me yet. This is new for me, so I'm wondering if anyone can confirm my suspicions. Do I need to have an 'SR-IOV' setting enabled in my BIOS for this to work? I have IOMMU enabled and virtualization works fine, but I haven't found an option for enabling 'SR-IOV' specifically.

i checked your Bios Manual and cannot find any sr-iov setting either, iam afraid there is none and your suspicions are right.

Sorry, it's the first version with web setting page. May cause some file conflicts. Could you please try remove the old plugin then install the new one?
