I have a Dell Precision M6600 Mobile Workstation (really big laptop). Specs:
CPU: i7 2820QM
GPU: Nvidia K4000M
According to http://ark.intel.com/products/52227/Intel-Core-i7-2820QM-Processor-8M-Cache-up-to-3_40-GHz : Intel® HD Graphics 3000
So I have two GPUs. However, there's no mention of the iGPU in the BIOS (usually it has an option for which to use as primary), it's not listed in lspci, and if I try to force the K4000M to not be used, the system won't output an image.
Things I've done to be sure everything is setup correctly:
- Enabled Vt-d in BIOS.
- Enabled IOMMU in the kernel.
- Verified the IOMMU groups are valid (the dedicated GPU is in it's own group).
- Bound the PCI ids to vfio-pci.
-
Set vfio's modules for boot with mkinitcpio.
No display on boot.
Undid #5.
- Created a Windows Virtual Machine with QEMU/KVM using virt-manager using UEFI (OVFM).
So I feel like I'm 90% of the way there. My GPU, CPU, motherboard, and such seem to support everything. It's just the iGPU that's not showing up.
I've tried being sure that the nvidia proprietary driver and the nouveau open source driver are blacklisted and that vfio-pci gets the dedicated GPU, but that's what causes it to boot without a display.
I'm gonna guess the iGPU is connected to one of my outputs and not the laptop monitor perhaps? I do have a VGA, DisplayPort, and HDMI out on this laptop.
