GPU passthrough on 8.0

i have read a few guides and watched a few videos

what i want - if possible - is to see my nvidia card pop up in a win11 vm and not the basic m$ card

how is that best done for a noob?

and can the same be done for the chipset? the win11 driver installer checks for mfg and it stops as it can not see AMD as mfg

drivers for the sound card worked fine, but it did not detect any sound card
now i have....

when i execute update-initramfs -u -k all i get

root@proxmox:/home/bo# update-initramfs -u -k all
bash: update-initramfs: command not found

root@proxmox:~# update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-6.2.16-3-pve
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.
Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.

IOMMU Passthrough Mode​

If your hardware supports IOMMU passthrough mode,

how do i know if it does?
i assume i got it right

root@proxmox:~# dmesg | grep -e DMAR -e IOMMU -e AMD-Vi
[ 0.000000] AMD-Vi: Using global IVHD EFR:0xf77ef22294ada, EFR2:0x0
[ 0.228670] pci 0000:00:00.2: AMD-Vi: IOMMU performance counters supported

further reading....

The most used variant of PCI(e) passthrough is to pass through a whole PCI(e) card, for example a GPU or a network card.

that is not an option as i have desktop on the host itself... i wanted to combine everything in the same box, hence a client-host setup with 2 machines is not what i'm going for
