iGPU Passthrough (Ryzen 5 5600G)

[Tim1]

Hallo Zusammen,

ich scheitere gerade daran die iGPU durchzureichen.

Folgendes habe ich bereits gemacht. (Anleitung https://pve.proxmox.com/wiki/Pci_passthrough)

Aktuell sagt er mir beim Start der VM: TASK ERROR: Cannot open iommu_group: No such file or directory

Jemand eine Idee?

servus,
hast du schon im BIOS nachgesehen ob du dort IOMMU aktivieren kannst?

Guten Morgen, ich habe nochmal nachgeschaut, stand auf Auto. Ich hab es jetzt auf enabled gesetzt.

Liegt es evtl. auch daran? So wie es aussieht ist Rennoir IOMMU keiner IOMMU Gruppe zugeordnet. Oder lieg ich da falsch? Wenn ja wie ordne ich die einer Gruppe zu?

Leider sind, soweit ich weiß, interne Grafikkarten meist etwas problematisch da sie z.B. in ihrer IOMMU Gruppe andere Geräte haben die der Host braucht. Das die interne Grafik gar keine hat hab ich bis jetzt noch nicht gesehen.

 

[Tim1]

Hat sonst noch jemand eine Idee?

 

[bluesite]

brauchst du die interne GPU für ne VM oder nur für Hardware Unterstützung bei z.B. Emby oder Plex?

Nur für eine VM dort brauch ich auch den Audio Controller

 

[Tim1]

Niemand eine Idee? Zumindest wie ich den Audio Controller aktiviert und durchgereicht bekomme?

For linux it works with seabios because the vbios non uefi. For Windows does not work with a seabios due to "device does not support requested feature x-vga" error and without x-vga it cause code 43 error.
