Hello, i've read many threads about passthrough issues with these iGPU's, what's disturbing is despite most of people fail at passthrough, some succeed :) After trying many guides, I think my system is a bit overloaded with non useful config files / parameters. Could someone who was successful with this CPU family help me with cleaning and finding the right config ? My ultimate goal is passthrough a windows 11 VM, but if it's not possible, a Ubuntu 22.10 would be ok :) Last usecase, if none of these 2 is possible, passthrough the iGPU to a Jellyfin container :)

for the time being, I have a no signal / black screen when i passthrough a VM (win11 or ubuntu)

PS: sorry for the LONG post. Thanks in advance !

I am using this.

Install opt-In Kernel 6.1 for Proxmox

/etc/default/grub
Code: 
GRUB_CMDLINE_LINUX_DEFAULT="quiet initcall_blacklist=sysfb_init intel_iommu=on iommu=pt"
/etc/modeprobe.d/i915.conf
Code: 
options i915 enable_guc=3
/etc/modules
Code: 
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
Code: 
update-grub
reboot

If you want to passthrough to LXC
/etc/pve/lxc
add to the LXC conf file
Code: 
# Allow cgroup access
lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.cgroup2.devices.allow: c 29:0 rwm

# Pass through device files
lxc.mount.entry: /dev/fb0 dev/fb0 none bind,optional,create=file
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir
lxc.mount.entry: /dev/dri/renderD128 dev/renderD128 none bind,optional,create=file

Boot up the container (I use Debian)
/etc/apt/sources.list
add non-free
Code: 
deb http://ftp.debian.org/debian bullseye main contrib non-free
deb http://ftp.debian.org/debian bullseye-updates main contrib non-free
deb http://security.debian.org bullseye-security main contrib non-free
then
Code: 
apt-update
apt install intel-media-va-driver-non-free

You should have hardware encoding enabled, just install Jellyfin / Plex / Emby / tdarr and enjoy...
Hopefully.

thanks!
I managed to passthrough the iGPU with a jellyfin LXC. Now i'm wondering if passing through a VM is possible on the same node, because if I blacklist i915 from proxmox, it won't be available for jellyfin ? anyway I couldn't manage to pass iGPU for a VM yet ....

I am using this.

/etc/default/grub


Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet initcall_blacklist=sysfb_init intel_iommu=on iommu=pt"
Click to expand...

what's the purpose of this ? :
quiet initcall_blacklist=sysfb_init
Click to expand...

I believe this also allows you to passthru to VM, but I am not sure, as I have not tried.
