Intel 520 Integrated Graphics Card Passthrough Issues on Proxmox 6.2-4

[tachang]

I am having issues getting my Intel 520 integrated graphics card passing through on qemu. I am using Proxmox Virtual Environment 6.2-4.

I tried a number of different things documented here:
https://gist.github.com/tachang/66d0db979aa6d9149a5a284e15b9bd74

For the most part just getting a blank screen and fault code.

`DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear

Im having same issue.

Its an laptop dell 2 in 1 with 6200U processor and intel 520 gpu. I manage to passthrought however this error occors and I get no HW accelation

I have managed to get this to work.

My string was:
-device vfio-pci,host=0000:00:02.0,id=hostpci0,bus=pci.0,addr=0x10,x-igd-opregion=on,romfile=/usr/share/kvm/i915ovmf.rom

And I used this ROM: https://github.com/HouQiming/i915ovmfPkg

You have to make sure you are on the right version of proxmox. And then you have to edit the conf file manually and put in the romfile and x-igd-opregion=on.

im using

PVE Manager Version
pve-manager/6.2-4/9824574a

same as you I believe. Tried your steps.. still no luck.

May you provide your confs update, please?

Ubuntu 20.04.1, gpu get llvmpipe... no hw acc at all.

what am i missing?

thank you

 

[tachang]

When I wrote the thread it was
Virtual Environment 6.2-4 which had a bug.

You need Virtual Environment 6.2-6

 

[lixaotec]

thanks!
Im digging in to update it.
Just curious if is this version only avaliable for enterprise subscription? Iḿ only have community.
Im trying to update, i will come here after with news.

 

[tachang]

You can use community edition too.

 

[lixaotec]

PVE Manager Version

pve-manager/6.2-10/a20769ed

nice!! , now lets see if passtr. works

 

[lixaotec]

still nothing...

(im conectiong trhough xrdp, may it affects?)

I may be missing some config..

Also, i noticed that i see ubuntu screen at my laptop monitor.

 

[lixaotec]

So frustrating.. xrdp keeps falling back to llvmpipe ..

Will have to give up keep windows running
