My grub line :"GRUB_CMDLINE_LINUX_DEFAULT="rd.modules-load=vfio-pci quiet intel_iommu=on,igfx_off pcie_acs_override=downstream" (igfx_off is because i cannot boot otherwise, got some graphic glitch at boot, if you don't have it feel, free to remove itr"Don't forget to update grub afterwards. It is weird though, rd.modules-load is on others tutorials but not on arch wiki.I believe that was the issue i had when first trying to get vfio to grab the device on antergos first time i wanted to do this.2016-04-23 0:10 GMT+02:00 Alex Williamson <alex l williamson gmail com>:_______________________________________________On Fri, Apr 22, 2016 at 4:06 PM, Brett Peckinpaugh <erylflynn gmail com> wrote:To start I am now running Arch with the VFIO kernel, I did not compile with the i915, my machine failed to boot with that last time. 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?

intel_iommu=on pcie_acs_override=downstream rd.driver.pre=vfio-pciYou're applying Fedora instructions to Arch, rd.driver.pre apparently doesn't do anything on Arch. Look in the archive for the past couple weeks, I believe there are some working instructions there.
