修改配置后 Arch Linux 卡在“正在加载版本 240”

我正在尝试让 GPU 直通在虚拟机上运行。我一直在关注这个视频https://www.youtube.com/watch?v=6FI31QDtyy4。我所做的和他在视频中所做的区别在于 mkinitcpio 配置中的模块，我使用了“MODULES=(vfio_pci vfio vfio_iommu_type1 vfio_virqfd)”因为视频有点过时了。

所以我做的是

  • 在 grub params 中添加 intel_iommu=on
  • 检查我的系统是否支持 IOMMU，我运行了“dmesg | grep -e DMAR -e IOMMU”
  • 将“options vfio-pci ids=10de:10f0,10de:1b81”添加到 vfio.conf
  • 如上所述修改 mkinitcpio.conf
  • 运行‘mkinitcpio -p linux’
  • 修改 qemu.conf（可能不相关）
  • 运行“systemctl enable --now libvirtd”和“systemctl enable virtlogd.socket”
  • 重新启动并返回 Windows 10（非双启动。我正在通过 USB 记忆棒（非 LIVE USB）运行 arch）（尝试添加 vm 但失败了，因为我没有执行 ntfs-3g 操作）
  • 从 Windows 10 回来并在 fstab 中添加“UUID=061A04D11A04C023 /media/Data/ntfs-3g defaults 0 0”
  • 在 /etc/default/grub 中将 'GRUB_CMDLINE_LINUX_DEFAULT="quiet"' 更改为 'GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"'
  • 重新启动并停留在“正在加载版本 240（当我从 params 中删除 intel_iommu=on 时，它启动正常）

第一次启动时 iommu 工作正常，我使用 GPU 作为输出。上次启动时 GPU 不工作（无信号），我尝试使用 iGPU。此外，我还查看了 Arch 官方 wiki 中有关 PCI 直通的内容，步骤非常相似

/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=()

/etc/modprobe.d/vfio.conf：

options vfio-pci ids=10de:10f0,10de:1b81

我太笨了，我把显示器插到 GPU 上，插到 iGPU 上后它就工作了。确保在 BIOS 中将其设为主输出
