Boot problem on Debian guest (on proxmox host), works after reloading i915.ko

[kugel-]

Hello,

I installed this in a Debian VM (I understand that I do need this driver on the host as well as the VM right?).

I experience the following problem: On boot, the i915 driver fails to initialize the VF properly. However, if I reload i915.ko after boot it works fine. The guest is bootet with i915.enable_guc=3 and runs on Debian's 6.5 kernel (from backports).

dmesg (reloading i915.ko after ~40s)

I wonder if something is missing from my initrd that's later available on the rootfs? Any module dependency perhaps?

Maybe the system is loading the original i915 driver of Debian

i have this problem too. when i set the model q35 it shows the same as yours ,i am using 6.5.0-0.deb12.4-amd64 too. when i change the model to i440fx it ,it shows sudo dmesg|grep i915 [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-6.5.0-0.deb12.4-amd64 root=/dev/mapper/debian--vg-root ro quiet splash i915.enable_guc=3 [ 0.022749] Kernel command line: BOOT_IMAGE=/vmlinuz-6.5.0-0.deb12.4-amd64 root=/dev/mapper/debian--vg-root ro quiet splash i915.enable_guc=3 however The GPU was not loaded correctly cpu：intel N100 pve kernel 6.5.13-3-pve I have also test in 6.1

Does anyone have any ideas？

[1402366912]

maybe as an alternative we canautomatically run scripts at startup

!/bin/bash

modprobe -r i915 sleep 5
modprobe i915

[1402366912]

要设置在系统启动后的30秒执行该脚本，你可以使用 systemd 的 systemctl 命令和定时器来实现。下面是如何设置的步骤：

1. 创建定时器文件： 创建一个文件 reload-i915.timer，其中包含定时器的配置。打开终端，输入以下命令：

   sudo nano /etc/systemd/system/reload-i915.timer

   在打开的编辑器中，粘贴以下内容：

   [Unit]
   Description=Reload i915 module 30 seconds after boot
   
   [Timer]
   OnBootSec=30s
   Unit=reload-i915.service
   
   [Install]
   WantedBy=multi-user.target

   这个配置文件定义了一个定时器，在系统启动后30秒触发，并指定执行 reload-i915.service 服务单元。

2. 创建服务文件： 创建一个文件 reload-i915.service，用于定义在定时器触发时要执行的操作。在终端中输入以下命令：

   sudo nano /etc/systemd/system/reload-i915.service

   在打开的编辑器中，粘贴以下内容：

   [Unit]
   Description=Reload i915 module
   
   [Service]
   Type=oneshot
   ExecStart=/bin/bash -c '/sbin/modprobe -r i915 && sleep 5 && /sbin/modprobe i915'
   
   [Install]
   WantedBy=multi-user.target

   这个配置文件定义了一个一次性服务，它在执行时会卸载并重新加载 i915 模块。

3. 启用定时器和服务： 完成上述文件的编辑后，保存并关闭编辑器。接下来，通过以下命令启用定时器和服务：

   sudo systemctl daemon-reload
   sudo systemctl enable reload-i915.timer

   这些命令会重新加载 systemd 管理的单元文件并启用定时器，使其在系统启动后的30秒触发。

现在，系统每次启动后的30秒钟，将会尝试重新加载 i915 模块，以解决可能的初始化问题。请测试一下，看看是否能解决你遇到的问题。

this is working well
