iGPU Passthrough to LXC

Setting up fstab to auto-mount NAS shares via SMB/CIFS

Install Jellyfin via Proxmox Helper Scripts
Select custom installation and be sure the container is created as privileged vs. unprivileged so the NFS/CIFS mounts and hardware transcoding can work properly.
Power the LXC container down to make modifications 3. Go to Options > Features and click Edit
Add NFS, SMB/CIFS as needed
Power on the LXC container
Install CIFS Utils and/or NFS Utils (use sudo if not logged in as root user)
```
bash apt install cifs-utils nfs-common
```
Edit the fstab
```
nano /etc/fstab
```

Go to the first blank/open line and enter the following:

# CIFS/SMB Mount
# //192.168.2.6/Media     /mnt/media      cifs    user=jellyfin,password=jellyfin,iocharset=utf8,noperm   0       0
# NFS Mount
192.168.2.6:/mnt/user/Media     /mnt/media      nfs     rw,hard 0       0

Save changes to the fstab

Configuration to pass through iGPU

https://jellyfin.org/docs/general/administration/hardware-acceleration/intel#lxc-on-proxmox

Load the correct graphics driver for the container
```
nano /etc/modprobe.d/i915.conf
```
Add the following line to the blank file and save:
```
options i915 enable_guc=3
```
Modify the LXC container's config file where the ###.conf is the ID of the container
```
nano /etc/pve/lxc/101.conf
```

Add the following lines to the end of the container config (the Proxmox Helper Script may have added these lines already - no need to add them 2x if they are already there):

lxc.cgroup2.devices.allow: c 226:0 rwm 
lxc.cgroup2.devices.allow: c 226:128 rwm 
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

Pass through the iGPU
```
chmod -R 777 /dev/dri/*
```
Verify the passthrough in the Jellyfin LXC
```
ls /dev/dri
```
Install drivers in the container
```
apt install vainfo intel-gpu-tools
```
8. Verify driver install status and supported codecs by running the vainfo command and intel_gpu_top 9. Make sure user and group settings are correct
```
usermod -aG video jellyfin usermod -aG input jellyfin usermod -aG render jellyfin
```
10. Restart the Jellyfin service for changes to take effect
```
systemctl restart jellyfin.service
```
11. Select Intel QSV/QuickSync transcoding in the dropdown and select the correct codecs. - Depending on the generation of Intel CPU/iGPU you are using, you may/will likely need to enable both low power modes. 12. To configure and verify low power (LP) mode, install the following:
```
apt update && apt install -y linux-firmware
```

Add the following to the host system to enable loading of GuC and HuC low power firmwares:

mkdir -p /etc/modprobe.d sh -c "echo 'options i915 enable_guc=2' >> /etc/modprobe.d/i915.conf"

Update the initramfs and grub
```
update-initramfs -u && update-grub
```
Reboot the system for the changes to take effect

Verify the firmware status and be sure there is no ERROR or FAIL in the output

dmesg | grep i915 cat /sys/kernel/debug/dri/0/gt/uc/guc_info cat /sys/kernel/debug/dri/0/gt/uc/hu`_info`

or FAIL in the output

dmesg | grep i915 cat /sys/kernel/debug/dri/0/gt/uc/guc_info cat /sys/kernel/debug/dri/0/gt/uc/hu
