I'm finally get new hardware (i7 4771 + HD6950) with VGA passthrough and PRIME support and now I'm trying to evaluate what hardware/drivers can or can'd do.
I'm already find out that this sequence working fine for me:
This working fine and now I want ability to bind discrete GPU to host or VM without host restart (for now X restart is fine), but when I unload radeon module and load it again (a bit later) it's freeze host when I login after lightdm restart.
So I wonder it is possible to do that at all? What is right way to unload radeon module?
I'm already find out that this sequence working fine for me:
- Boot host with "radeon" blacklisted and monitors connected to iGPU.
- Use discrete GPU in Linux/Windows guest using pci-assign or vfio-pci.
- Stop VM and X server on host.
- Unbind GPU from other drivers and run "modprobe radeon audio=0" to use it on host.
- Start new X session and run applications on discrete GPU using DRI_PRIME=1
