当前我使用的PVE版本是`7.3-3`当前的内核是`5.15.74`，网上教程试了一圈发现都不行。最后发现问题是内核的原因。

# 0x01

首先升级宿主机内核

```sh
apt update
apt upgrade -y
apt install pve-kernel-5.19 -y
```

查看固件

```sh
cd /lib/firmware/i915 && ls ehl_guc*.bin &&  ls ehl_huc*.bin &&  ls icl_dmc*.bin
```

修改配置并重启

```sh
echo "options i915 enable_guc=3" >> /etc/modprobe.d/i915.conf
reboot
```

启动后检查

```sh
journalctl -b -o short-monotonic -k | egrep -i "i915|dmr|dmc|guc|huc"
```

输出的内容中有`GuV` `HuC`就代表驱动成功

```sh

docker映射设备`/dev/dri:/dev/dri`

jellyfin 硬解选择QSV

如果中间还加了一层`LXC`就在配置上添加

```
lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.cgroup2.devices.allow: c 29:0 rwm
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir
lxc.apparmor.profile: unconfined
```
