Currently I can't seem to get VFIO to claim the devices I want to pass-through. You can see kernel driver is still nvidia. I added my configs below. I even tried a script. Every time I modify mkinitcpio.conf I regenerate my intramfd with mkinitcpio -p linux-vfio What am I missing? <meta http-equiv="content-type" content="text/html; charset=utf-8"> lspci -nnk -d 10de:1087 <blockquote>02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 560 Ti 448 Cores] [10de:1087] (rev a1) Subsystem: NVIDIA Corporation Device [10de:0000] Kernel driver in use: nvidia Kernel modules: nouveau, nvidia_drm, nvidia </blockquote> /etc/mkinitcpio.conf <blockquote>MODULES="vfio vfio_iommu_type1 vfio_pci vfio_virqfd" </blockquote> kernel boot options. <blockquote>intel_iommu=on pcie_acs_override=downstream rd.driver.pre=vfio-pci </blockquote> /etc/modprobe.d/VFIO.conf <blockquote>options vfio-pci ids=10de:1087,10de:0e09 </blockquote> modinfo vfio-pci <blockquote>filename: /lib/modules/4.5.1-1-vfio/kernel/drivers/vfio/pci/vfio-pci.ko.gz description: VFIO PCI - User Level meta-driver author: Alex Williamson <a class="moz-txt-link-rfc2396E" href="mailto:alex.williamson@redhat.com"><alex.williamson@redhat.com></a> license: GPL v2 version: 0.2 srcversion: C2A1332D492B2BE5378D1E1 depends: vfio,irqbypass,vfio_virqfd intree: Y vermagic: 4.5.1-1-vfio SMP preempt mod_unload modversions parm: ids:Initial PCI IDs to add to the vfio driver, format is "vendor:device[:subvendor[:subdevice[:class[:class_mask]]]]" and multiple comma separated entries can be specified (string) parm: nointxmask:Disable support for PCI 2.3 style INTx masking.
