Passthrough iGPU (no.lastname.nz)

OK, this is really annoying...

I have an intel based PC that I use as a server that is sitting under the lounge TV that I was using to drive the TV with a linux VM using pci pass-through of the iGPU.

Every thing was working well, then all of a sudden there was no output to the TV. The iGPU still works fine during boot.

I have just updated proxmox to the latest, and no better results.

I sometimes will get it to work on a new install of a vm, but on reboot of the vm it all stops.

Any thoughts on where/what to look at?

If you're passing the iGPU to the VM then the host can't use it if the VM is on.

If your host supports SR IOV, then have a look at this repo: https://github.com/strongtz/i915-sriov-dkms

Installing this on Proxmox and your guest means the guest(s) and host to use the iGPU at the same time.

I'm not sure if it's in mainline somewhere but I had to install this DKMS to get it working.

Just realised your driving the TV with a VM. This probably isn't relevant then.
