Desperate with Proxmox 8.4 and GPU Passthrough Geforce GTX1650

[rjcab]

Hello,

I am raising a new post for GPU Passthrough Geforce GTX1650 and Proxmox 8.4. There is a little progress:

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt initcall_blacklist=sysfb_init"

update-grub
update-initramfs -u -k all

root@pve:~# lspci -nnk -s 01:00.0 -s 01:00.101:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:10fa] (rev a1)        Subsystem: Gigabyte Technology Co., Ltd Device [1458:4026]        Kernel driver in use: snd_hda_intel        Kernel modules: snd_hda_inte


/etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:1b80,10de:10f0 disable_vga=1

/etc/modprobe.d/blacklist-nvidia.conf
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
blacklist rivafb
blacklist snd_hda_intel

update-initramfs -u -k all

Then I reboot and I got:

root@pve:~# lspci -nnk -s 01:00.0 -s 01:00.1
01:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:10fa] (rev a1)
        Subsystem: Gigabyte Technology Co., Ltd Device [1458:4026]
        Kernel driver in use: vfio-pci
        Kernel modules: snd_hda_intel
root@pve:~#

So still an issue, I still have a load module which is not vfio .

I you have any ideas.

Thanks

nvidia card is easy to passthrough without additional setting, i am passing through it to a windows 11 VM since PVE8 and now PVE9.

simply adding it to your VM should work just fine.

many thanlf gor your feedback. If I inderstand well, you started from a fresh install of Proxmox 8 or 9.0 and you did not modify grub or modules files or anything else, just the modification with the graphic UI above ? I am asking because if you do not that GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on", DMAR will be not activated ?

Thanks

i have this same as yours

/etc/modprobe.d/blacklist-nvidia.conf
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
blacklist rivafb
blacklist snd_hda_intel

Thanks. So to recap only adds in modprobes and nothing in grub ?

Many thanks

Fresh install of pve8.4.

I add the following content:

cat /etc/modprobe.d/blacklist-nvidia.conf
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
blacklist rivafb
blacklist snd_hda_intel

I did not run update-initramfs -u -k all

I just reboot and the Proxmox crash, not accessible via SSH even icmp request failed.

If you have any ideas please
