I've pretty new to Arch Linux. I'm trying to get GPU passthrough to work on a VM. I've been following this video https://www.youtube.com/watch?v=6FI31QDtyy4. The differences between what I did and what he did in the video was modules in mkinitcpio config thingy, I used 'MODULES=(vfio_pci vfio vfio_iommu_type1 vfio_virqfd)' instead because the video was a bit outdated.

So what I did was

• Add intel_iommu=on in grub params


• Checked that my system supports IOMMU, I ran 'dmesg | grep -e DMAR -e IOMMU'


• Adding 'options vfio-pci ids=10de:10f0,10de:1b81' to vfio.conf


• Modifying mkinitcpio.conf as described above


• Running 'mkinitcpio -p linux'


• Modifying qemu.conf (prob not related)


• Running 'systemctl enable --now libvirtd' and 'systemctl enable virtlogd.socket'


• Reboot and go back to Windows 10 (NOT DUALBOOTED. I'm running arch off a USB STICK (NOT LIVE USB)) (Tried adding a vm but failed because I didn't do the ntfs-3g thingy)


• Came back from Windows 10 and added 'UUID=061A04D11A04C023 /media/Data/ ntfs-3g defaults 0 0' in fstab


• Changed 'GRUB_CMDLINE_LINUX_DEFAULT="quiet"' to 'GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"' in /etc/default/grub


• Rebooted and stuck at "Loading version 240 (when I remove the intel_iommu=on from params, it booted just fine)

First boot that iommu worked, I used my GPU as output. I tried iGPU after GPU didn't work on the last boot (No Signal). Also I've checked Arch's official wiki about PCI passthrough and the steps were pretty similiar

/etc/mkinitcpio.conf:

# vim:set ft=sh

# MODULES

# The following modules are loaded before any boot hooks are

# run.  Advanced users may wish to specify all system modules

# in this array.  For instance:

#     MODULES=(piix ide_disk reiserfs)

MODULES=(vfio_pci vfio vfio_iommu_type1 vfio_virqfd)



# BINARIES

# This setting includes any additional binaries a given user may

# wish into the CPIO image.  This is run last, so it may be used to

# override the actual binaries included by a given hook

# BINARIES are dependency parsed, so you may safely ignore libraries

BINARIES=()



# FILES

# This setting is similar to BINARIES above, however, files are added

# as-is and are not parsed in any way.  This is useful for config files.

FILES=()



# HOOKS

# This is the most important setting in this file.  The HOOKS control the

# modules and scripts added to the image, and what happens at boot time.

# Order is important, and it is recommended that you do not change the

# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for

# help on a given hook.

# 'base' is _required_ unless you know precisely what you are doing.

# 'udev' is _required_ in order to automatically load modules

# 'filesystems' is _required_ unless you specify your fs modules in MODULES

# Examples:

##   This setup specifies all modules in the MODULES setting above.

##   No raid, lvm2, or encrypted root is needed.

#    HOOKS=(base)

#

##   This setup will autodetect all modules for your system and should

##   work as a sane default

#    HOOKS=(base udev autodetect block filesystems)

#

##   This setup will generate a 'full' image which supports most systems.

##   No autodetection is done.

#    HOOKS=(base udev block filesystems)

#

##   This setup assembles a pata mdadm array with an encrypted root FS.

##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.

#    HOOKS=(base udev block mdadm encrypt filesystems)

#

##   This setup loads an lvm2 volume group on a usb device.

#    HOOKS=(base udev block lvm2 filesystems)

#

##   NOTE: If you have /usr on a separate partition, you MUST include the

#    usr, fsck and shutdown hooks.

HOOKS=(base udev autodetect modconf block filesystems keyboard fsck)



# COMPRESSION

# Use this to compress the initramfs image. By default, gzip compression

# is used. Use 'cat' to create an uncompressed image.

#COMPRESSION="gzip"

#COMPRESSION="bzip2"

#COMPRESSION="lzma"

#COMPRESSION="xz"

#COMPRESSION="lzop"

#COMPRESSION="lz4"



# COMPRESSION_OPTIONS

# Additional options for the compressor

#COMPRESSION_OPTIONS=()
