首先是位中文大佬？

我刚刚把系统升级到了6.12 rc2，安装了插件，也显示安装成功并重启了，但是并没有看到vf设备呢？

    I have now adapted the plugin so that users are able to install it on Unraid 6.12.4 without any workarounds and to make sure that packages for upcoming Unraid versions are available. The new plug

有的，最后两行就是

i tryed the new version but no luck, iam near i can smell it.... its close to working.. i make some sort of mistake on my behalve..

 

steps i did

 

1) in Bios enable sriov

2) install i915-sriov Plugin from the link (for now) you provide

3) i checked modprobe.D there is a file called i915-sriov.conf inside that file this is generated

# disable autoload old i915 module on boot
  blacklist i915 
  options i915 enable_guc=7
 

4) i checked my go file and as far i see the Plugin created all entries, right?

5) reboot ---> still no VF's but with dmesg | grep i915 i find this now

I update the plugin, add sleep 3 after modprobe i915 to ensure it is fully loaded. And add /usr/local/sbin/vfio-pci. You may reinstall the plugin and have a try.

 

I am very grateful that you can help me to test my first plugin.

 

is "add sleep 3 after modprobe i915" a typo? or could you be more specific what is needed here?

The PF is worked. What the output of "cat /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs". And have you tried running "echo 4 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs" manually?

During my multi reboot test, the terminal complain that sriov_numvfs not found several times when run to "echo 4 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs" in go script. Then I found out that it is because of i915 sriov module not fully loaded. So I add "sleep 3" after "modprode i915" to wait 3 seconds. Then I have no "sriov_numvfs not found" issues in my reboot tests.

no waaaay...... it works....  iam pre clearing a  disk right now... but i will try the sleep command to. i cant freaking believe it :D awsome, 

the sleep command could be used as alternative branch as Plugin.

目前SR-IOV没有帧缓冲区，无法输出显示。我们只是Intel驱动的搬运工，没有能力做到更多，还得看Intel的后续开发更新。

unraid.thumb.jpg.c9ff54d04fe666104efa49830ea7db69.jpg

 

 

so i  tested some more... i cant get it to work on boot.. idk why. could there be something wrong  with my go file? 

when i add "echo 4 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs" manually i have my 4 FVs when stubbed already to use.

But when i reboot they are gone and i need to put in "echo 4 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs" manually.

 

i mean a cron on startup will do the job but strange enough.

 

 

So i spun up an test VM win 10

 

I did 

 

1) in Bios enable sriov

2) Intel GPU TOP

3) install i915-sriov Plugin from the link (for now) you provide

4) add the ammount of FVs in the go file , echo 4 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs 

5) I need to make an userscript cron on first boot array "echo 4 > /sys/devices/pci0000\:00/0000\:00\:02.0/sriov_numvfs"

5) reboot

 

6) The PF (00:02.0) could be used by Unraid host. And the VFs(00:02.x) are only used for passthrough to VMs

7) install any VM 

8 ) install the intel driver (Linux) or gibe the VM some time Windows update gets the driver on its own.

12代CPU完美虚拟化，完美解码4K高清原盘。但是存在一个问题导致Docker 容器jellyfin硬解不显示画面。

Edited by 程世平

The plugin made it possible to have a working GPU without code 43 in a Windows 11 VM. 

 

Previously, when I selected 00:02.0 video card, the screen on the laptop went from Unraid Console output to black, and I could RDP into Windows. But no screen output on the laptop. This gave me the Code 43 and a message in the log stating that it couldn't find a ROM.

 

image.png.0dbe430716857aa89eeb08b9c0f18742.png

 

When I select 00:02.1 the laptop's screen remains to outputs the Unraid console output.  Within Windows 11 (via RDP) I can see that video card is working (no more Code 43). 

 

What about getting output on a physical connection on the (in my case) laptop or on the screen of the laptop?

谢谢大佬开发的实用插件。这个在13带U上应该也可以吧？

手动执行 echo 2 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs，提示 -bash: echo: write error: Numerical result out of range

可以帮我看看问题出在哪里吗。

手动执行 echo 2 > /sys/devices/pci0000:00/0000:00:02.0/sriov_numvfs，提示 -bash: echo: write error: Numerical result out of range

可以帮我看看问题出在哪里吗。

 

你好，可以看看“cat /sys/devices/pci0000:00/0000:00:02.0/sriov_totalvfs” 和 “lspci -vs 00:02.0 ” 这两个命令的输出吗？

很遗憾，totalvfs显示是0，赛扬这个U虽然支持SR-IOV功能，但可用的vf是0，分配不出来虚拟显卡。

感谢解答，以后升级一下CPU
