Hi everyone,
After my installation of Proxmox VE 6.2 on my Lenovo T450s, I started to work on Disk Passthrough and PCIe Passthrough.
I follow this guide and successfully passthrough my Windows 10 Bare Metal installed SSD.
https://pve.proxmox.com/wiki/Physical_disk_to_kvm

For the PCIe Passthrough, I follow these guides, but I cannot get most of the PCIe device work. Although I have Vt-d enabled in BIOS and see the IOMMU groups, the Web Console keep say the error " No IOMMU detected, please activate it. ". I found that the Intel HD Graphics 5500 was set to IOMMU Group [-1]. However, I still able to passthrough other device, but only the Realtek RTS5227 PCI Express Card Reader (SD Card Reader) work under this condition.

To check the compatibility issue, I installed Proxmox VE 5.4 and upgrade to 5.4-15. In 5.4-15, the IOMMU error does not exist, and Intel HD Graphics 5500 was set to IOMMU Group [1]. However, I still cannot get other PCIe Device work in Passthrough, only SD Card reader work.

https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/

Here is my log in Proxmox 5.4-15.

Also, here is the file details and the Error Code Capture when I tried to Passthrough a Intel Wi-Fi M.2. Module. I rtried to uninstall the driver and reboot the VM but no luck.

I have tried both Unraid and ESXi, only unraid recognise the Wi-Fi as USB device, but have malfunction, always disconnect...
Under this condition, what could i do to make any PCI passthrough device work in Proxmox VE?

do you mind sharing the output for: dmesg | grep -e IOMMU -e iommu -e vfio -e Intel -e bug -e Bug

kernel boot params you could try: pci=noats nomodeset

Also, did you use the https://fedorapeople.org/groups/vir...ownloads/archive-virtio/virtio-win-0.1.171-1/ or https://fedorapeople.org/groups/vir...ownloads/archive-virtio/virtio-win-0.1.185-1/ ISO to install driver for the VM ? Also try out installing qemu-ga found on the ISOs.
Click to expand...

Thank you for your reply.
Here is the dmesg, I found that the PCIe address seems to have error, all ffffffff:ffffffff and no classes. Before I open the WIndows as VM, I had installed the virtio-win-gt-x64.msi in virtio-win-0.1.185-1.iso, but I am not sure the gt-x64 msi include the qemu-ga. I had also tried to install the "Virtio-win-guest-tools.exe", but meet an error.

Seems there is no option to install the 64bit QXL-WDDM-DOD in the virtio-win-0.1.185-1.iso
Also, applying the "nobar" and "text" in grub, the dmesg become shorter.

Hmm. Looks good. My suggestion is to gradually increase the number of vfio-pci ids you configured, that are a lot of ids. Try with one GPU and one other device first. Verify if all vfio-pci ids are correct, maybe also try nointmask=1 ?

Make sure to have IOMMU set to enabled in the BIOS, not auto. Enable UEFI, not csm.

consider commenting and rebooting

option kvm ignore.msrs=1


once: vfio-pci 0000:00:02.0: BAR 2: can't reserve message are gone it should work.


Here is the full boot string i use, do note thise entries in bold are AMD specific, you can remove them. If i remember well, putting video=efifb:eek:ff,vesafb:eek:ff before all others arguments as shown here may be of importance, try it i'd say.

iommu=pt amd_iommu=forced_isolation video=efifb:eek:ff,vesafb:eek:ff text nomodeset rcu_nocbs=0-15 amdgpu.runpm=0 pci=nobar,noats,big_root_window pcie_acs_override=downstream,multifunction kvm-amd.nested=0 profile=kvm pcie_pme=nomsi pcie_aspm=force pcie_ports=native

nointmask=1 already exists. I would like to know if "vfio-pci ids" you mean is equal to the PCI device. Currently I have tried all combination of the five device I added to vfio-pci, except the Intel chipset controller.

I would like to know more about the meaning of log. Is these messages normal?

So I should edit the vfio.conf to only these device? like

options vfio-pci ids=8086:1616,8086:160c,10de:1347 disable_vga=1 disable_idle_d3=1 nointmask=1

but I met this error when added nointmask=1, does it mean that the option is not available in Proxmox 5.4-15?

Important to know is the VM itself must also be configured appropriately. In my experience you must reinstall the VM sometimes for the PCI passthrough to catch on, or reboot the server.

CPU: host
Chipset: q35

When you add a PCI device it is a matter of experimenting with the settings for them. I found disabling 'all functions' and enabled 'PCI-Express' worked well for the GPU i have in passthrough.

Also, upload the Virtio ISO to proxmox and you can mount it as a cdrom in windows. Much easier.

What you do with PCI passthrough entirely depends on what you want. Passthrough is interesting for some purposes, not for all. For most devices (audio, usb) there is no need, just use kvm64 or host as CPU for maximum performance.

Do not pass through what you do not need exclusively. Typically you pass through devices you do not share with the host (server)

Configuring vfio-pci ids has consequences. It is also the reason i use amd_iommu=force_isolation and also experiment with one or more of pcie_pme=nomsi pcie_aspm=force pcie_ports=native

you can check options with modinfo vfio-pci

Understand, thank you very much to explain about the PCI Passthrough.

Unfortunately I don't a spare device to install a Windows VM for testing, under this condition, I would suspend the testing, backup the entire Windows disk and install the VM with SSD Passthrough to see any difference.

Btw, seems the parameter is 'nointxmask' not 'nointmask'? Do I need to rearrange the grub config GRUB_CMDLINE_LINUX_DEFAULT?
 
Yeah, sorry, typo, my bad,indeed, notintxmask=1

Not sure what you are trying to do really. At this moment i think all the configuration you have is working as expected and should not change much.

The option i do think you can work with are

  • check: dmesg | grep -e IOMMU -e iommu -e vfio -e Intel -e bug -e Bug -e BAR
    • when the BARx: can't reserve messages are gone you have fixed it.
  • realise there are just a few reasons why these messages change, reduce the number of changes you make per test and takes notes, rebooting when you make changes
    • configuration change in the bios
      • make sure to test if UEFI is enabled, c-states are enabled and iommu is enabled, and svm is enabled
        • in some cases setting it to enabled instead of auto works better
    • configuration change in the kernel boot parameters
      • these look fine to me, maybe test by appending one or more of pcie_pme=nomsi pcie_aspm=force pcie_ports=native
    • configuration change in the /etc/modrprobe.d option parameters
      • options kvm ignore_msrs=1
        • try booting with and without this module option enabled or commented/disabled
    • configuration change of the VM configuration
      • configure the CPU for your VM to be set host
        • kvm64 or default will considerably change the reliability of what you test, use host for all testing.

recommended reading on passthrough on Linux, never mind the distribution, Linux is Linux at this level.

https://wiki.archlinux.org/index.ph...serve_[mem]"_error_in_dmesg_after_starting_VM

These two lines may help your troubleshooting, i use a script specific to AMD CPU which works great and avoids reboot.

echo 1 > /sys/bus/pci/devices/0000\:00\:04.0/remove
echo 1 > /sys/bus/pci/rescan

and related to the above https://wiki.archlinux.org/index.ph...h_via_OVMF#UEFI_(OVMF)_Compatibility_in_VBIOS

An extensive article is here

Know it took me over a week to grow understanding and come to a fix, and diagnosed isolation of a non-fixable issue for which i found the reset script for amdgpu, persist and try things out.
 
Thank you very much, Joris.

Here is the new dmesg which I added the notintxmask=1 in /etc/modprobe.d/vfio.conf
Look like IOMMU not work after added this option
I found I just change the intel_iommu=on to intel_iommu=force_isolation without understanding

I would like to have a crosscheck with your successful sample before I start to test the combination of multiple parameter.

The GRUB_CMDLINE_LINUX_DEFAULT in your /etc/default/grub should be posted in #11:

iommu=pt amd_iommu=forced_isolation video=efifb:eek:ff,vesafb:eek:ff text nomodeset rcu_nocbs=0-15 amdgpu.runpm=0 pci=nobar,noats,big_root_window pcie_acs_override=downstream,multifunction kvm-amd.nested=0 profile=kvm pcie_pme=nomsi pcie_aspm=force pcie_ports=native

Currently my GRUB config is:

quiet intel_iommu=on iommu=pt pcie_pme=nomsi pcie_aspm=force pcie_ports=native pcie_acs_override=downstream,multifunction pci=nobar,noats nofb text nomodeset video=vesafb:eek:ff,efifb:eek:ff"

Seems that I can remove the quiet config? Also, what is the difference to add eek inside the video driver efifb and vesafb? I cannot find anything about the eek option.

May I have your vm config and dmesg so that I can know which part I should clear and which part I should achieve?

check here https://www.kernel.org/doc/html/v5.4/admin-guide/kernel-parameters.html
i have see eek, i have not looked into what it mean, may work for your setup

Use this line, you cannot simply copy stuff :)

iommu=pt intel_iommu=on video=vesafb:eek:ff,efifb:eek:ff pci=nobar,noats pcie_pme=nomsi pcie_aspm=force pcie_ports=native pcie_acs_override=downstream,multifunction nofb text nomodeset

i have no vm config, just q35 and host cpu

when you add the PCI device you have to select the IDS matching port number and figure out what setting works for the particular PCI device.
