ich versuche meine iGPU in vom Hostsystem in eine Windows 10 VM durchzureichen leider bisher ohne Erfolg. Ich wollte gerne wissen, ob von euch jemand mit ähnlicher Hardware erfolgreich war. Hardware: Gigabyte Auros Elite AX, CPU Intel 13900T
ich benutze einen Kernel in Version 6.1.8 und den Debian unstable Zweig
und übergebe beim booten folgende Parameter (/etc/default/grub)

sieht man, dass die GPU von vfio-pci angesprochen wird.
Code: Alles auswählen
00:02.0 VGA compatible controller [0300]: Intel Corporation Raptor Lake-S GT1 [UHD Graphics 770] [8086:a780] (rev 04)
DeviceName: Onboard - Video
Subsystem: Gigabyte Technology Co., Ltd Raptor Lake-S UHD Graphics [1458:d000]
Kernel driver in use: vfio-pci
Kernel modules: i915Ich habe Windows 10 ohne passthrough installiert. Hierzu verwende ich das Grafikinterface virtio. Nachdem Windows 10 installiert war habe ich den aktuellen Windows Patchstand eingespielt. VM Heruntergefahren und in der Konfiguration passthrough aktiviert (siehe libvirt XML-Datei). Windows bootet in diesem Fall ganz normal und man sieht im Gerätemanager ein neues PCI device als Grafikkarte. Windows 10 holt sich automatisch die Treiber installiert sie und zum Schluss steht im Gerätemanager eine UHD 770. Jedoch muss man Windows nach der Treiberinstallation neu starten.
Bisheriges Ergebnis: Die VM startet jedoch bleibt der Bildschirm schwarz und Windows läuft in den Reperaturmodus, da der Bootvorgang nicht erfolgreich war. Die Ausgabe läuft nur auf dem virtio mittels spice interface. Ich habe auch schon versucht nur die GPU der VM zu übergeben ohne virtio und spice-server. Leider ohne Erfolg. Sofern ich den passthrough deaktiviere fährt die VM(Windows 10) normal hoch.
Hat jemand noch Ideen was helfen könnte? Besten Dank,
Phil
