I have recently installed an AMD card for my host system, and my vm guest is also using an AMD card. On the host, I am using radeon driver but would like to prevent the guest getting radeon loaded. With pci-stub, with it built-in to the kernel, it would always grab pci devices before any other driver got the chance. However, with vfio-pci it seems to be loaded much later in the boot process, so radeon gets both cards before vfio-pci can bind it. As a result, I have tried building vfio and vfio-pci as modules and then including them in a Dracut-created initramfs as detailed at https://vfio.blogspot.com/2015/05/vfio-gpu-how-to-series-part-3-host.html. Even doing this, vfio-pci still gets loaded as late as it was built-in to the kernel, and so it does not get loaded before radeon (which is built-in).
Is there a way to get vfio-pci loaded earlier? Do I need to just build radeon as module to hope it gets loaded later also? Thanks, MB _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
