Hi,
I'm trying to get GPU passthrough to work, but the host machine locks
up hard at boot time.
My hardware specs:
- Intel i5 6500 CPU
- MSI H170A PC Mate ATX LGA1151 Motherboard
- MSI GeForce GTX 1070 Armor OC 8GB DDR5 256-bit Video Card
- Asus GeForce GTX 750 Ti 2GB STRIX Video Card
I'm running openSUSE Tumbleweed with Kernel 4.10.3 .
I've done the following:
1. Added a new grub entry for vfio, boot line is
linuxefi /boot/vmlinuz
root=UUID=280d6f04-6ad0-4647-96b9-580aec12bbdc ${extra_cmdline}
resume=/dev/sda3 splash=silent quiet showopts intel_iommu=on
2. Added the vfio modules to initrd
/etc/modules-load.d/local.conf :
drm_kms_helper
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
3. Bound the 750Ti video card to vfio
/etc/modprobe.d/99-local.conf :
options vfio-pci ids=10de:1b81,10de:10f0
When I boot with this configuration ( after regenerating the initrd
and the grub2.cfg file ) the boot process hangs early. I took some
pictures of the screen, see the below link.

I added iommu=pt to the boot line, but that did not help ( note that
in the gallery above the first picture is iommu=pt and the second one
is without ).
I am using the nvidia proprietary driver and would like to keep doing so.
Removing the options vfio-pci ids=... line allows the boot process to
proceeed normally.
Any advice on how to unblock this would be very welcomed.
Thanks,
Robert
