Hello Nex7, I am issuing the same problems, everything works until I install the nvidia driver on Win7

Hey Cubex, I haven't yet gotten this to work, BUT, I have good news for you, IF you have qemu-1.7.4 or less (you probably have 1.7.0 like I did, from 'pacman -S qemu'). You need 1.7.5+. I can confirm that with the latest 'qemu-git' (and 'seabios-git'), my VM was able to boot into Windows with graphics, but a bunch of other crap was screwed up. I am currently attributing this to TOO NEW a qemu, since the qemu-git package seems to be grabbing the absolute bleeding edge. After dinner I will try to get the package to pull down something post 1.7.5 but not bleeding edge.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

nbhs: Could you perhaps tell us when you update qemu-git and seabios-git aswell? Or are these the same packages we get from AUR?

These are git versions, so unless something breaks or fails to build theres no reason to update the package, you can use the AUR versions if you want since there are no extra patches needed

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Hi all,

I have a small probleme, on my VM i want to start OCCT and i got a BSOD "driver_irql_not_less_or_equal" i have not any other information on the BSOD screen.

I run on qemu 2.0.0-RC1 and kernel 3.14, i have two graphique card AMD HD 6870 (crossfire not enable) on the VM (just for testing).

On dmesg i have :

Hours of tests, 3.14 posted on OP for me was SLOW to a crawl, 3.13 old kernel posted before gets me almost native speed.

i am experiencing unexpected slowdown too. could you please specify your hardware, exact kernel version (if its 3.13.something) and patches?


For others if anyone cares i managed to get my R9 270X gpu running as secondary on libvirt i440fx (default) chipset. here is xml:

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

3.14 In the OP when he posted it the first time, and I dont see that changed.
If u want to know without decompressing the posted PKGBUILD file, here it is:
        'change-default-console-loglevel.patch'
        '0001-Bluetooth-allocate-static-minor-for-vhci.patch'
        '0002-module-allow-multiple-calls-to-MODULE_DEVICE_TABLE-p.patch'
        '0003-module-remove-MODULE_GENERIC_TABLE.patch'
        '0004-Revert-syscalls.h-use-gcc-alias-instead-of-assembler.patch'
        'http://repo-ck.com/source/gcc_patch/enable_additional_cpu_optimizations_for_gcc.patch$
        'radeon_load_vbios_from_file.patch'
        'acs.patch'
        'i915_314.patch'
        'debug_registers.patch'

Kernel version is pkgver=3.14 pkgrel=2 all from PKGBUILD. I dont use the 'override_for_missing_acs_capabilities.patch' since it did not work for me, however I edited the the the PKGBUILD to include a newer patch to fix the IOMMU group isolation from:  http://linux-kernel.2935.n7.nabble.com/ … 96884.html
pasted the patch into 'acs.patch'. The same thing was done for 3.13.6 (posted earlier from OP).

Hardware is a Lenovo W530, Ivy Bridge 3740QM, 8GB Ram. What was passthoughed is an external GPU, 680GTX to the virtual machine as mostly instructed from OP except I replaced all to virtio drivers. Performance of 3.13 is quite astounding, I still can't belive it.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

I'm unable to get qemu to boot the guest os. I've followed the instructions and used the packages in the main post, and have looked around the thread for a solution but I'm still clueless as to what could be wrong. Below is everything I could think of that will be helpful to troubleshoot, sorry that it's a bit much. Let me know if any more information would be helpful.

Command Run:

sudo qemu-system-x86_64 \
-enable-kvm \
-M q35 \
-m 1024 \
-cpu host \
-smp 6,sockets=1,cores=6,threads=1 \
-bios /usr/share/qemu/bios.bin \
-vga none \
-device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 \
-device vfio-pci,host=03:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on \
-device vfio-pci,host=03:00.1,bus=root.1,addr=00.1

Error:

qemu-system-x86_64: -device vfio-pci,host=03:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: error, group 1 is not viable, please ensure all devices within the iommu_group are bound to their vfio bus driver.

Setup:

Asrock z87 Extreme9
Intel Integrated Graphics (not in use, aside for post and bios)
Radeon R9 270x (guest) [03:00.0 and 03:00.1, pci-stubbed]
Radeon HD 6670 (host)  [04:00.0 and 04:00.1]



Drivers Tried:

radeon
fglrx (current)

Please note that both drivers have the same issue.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

@Eb: read the error. it says exactly what you have not done - you have not bound devices to vfio driver using vfio-bind script that you were supposed to make.

The error message says to make sure all of the devices in the group are bound to vfio.  The group, as you reported contains far more than just the secondary function of the device.  The IOMMU group on your system is large because the root port lacks PCIe ACS support.  If you wish to override that, look for the ACS override patch and options to use it (and caveats that enabling it implies).

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Just bought a PCIe USB 3.0 card for my machine. I was going to use it solely for passthroughing but Im having difficulty getting it to work.

Error Im receiving:

Im running with acs override patch included with nbhs kernel(3.13.6-1-mainline) at the moment.
I can see there are just too many devices in group 9, many of them I do not want to pass through. (It seems Intel didnt follow some standards here)

I see beckend found a new acs override patch written by awilliams, but this would be the first time I wouldve manually copy a patch for myself.

I get the following while trying to compile:

patching file drivers/pci/quirks.c
patch: **** malformed patch at line 67:         u16 device;

Any help is appreciated, still got a lot to learn smile

Update: Managed to implement the patch myself. The pci devices are now divided much more than before and I got my USB PCie card passthrough working!

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Still check if they are bound to vfio driver. For example my passed-through usb port 0000:00:13.0:

ls -la /sys/devices/pci0000:00/0000:00:13.0/driver/module/drivers

prints

pci:vfio-pci

Hope you can get it working. We have same GPU and im dying to find out if terrible performance im having is fault of GPU or what (hope its not discouraging!).

Could of sworn I already applied the patch, I'll look into it when i'm back at my system. Thanks.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Yeah 770 works great under new qemu and using ubuntu kernel +  pci acs patch, what problem where you facing Nex7?

I got net working and now im looking at audio, seems that is somewhat laggy and cuts often... tried both nbhs way of adding soundcard and using -soundhw parametere but result is same, all tried with alsa and pulseaudio as driver and still the same hmm

EDIT: Also I changed a bit the vfio-bind script to ignore already binded pci devices, so I can add vfio-bind on the qemu script

#!/bin/bash

if [ ! $USER = "root" ]; then
    echo "Run as root!"
    exit
fi

modprobe vfio-pci

base="/tmp/vfio-bind"
mkdir $base -p
for dev in "$@"; do
    path="$base/$dev"
    if [ ! -f $path ]; then
        touch $path
        vendor=$(cat /sys/bus/pci/devices/$dev/vendor)
        device=$(cat /sys/bus/pci/devices/$dev/device)
        if [ -e /sys/bus/pci/devices/$dev/driver ]; then
                echo $dev > /sys/bus/pci/devices/$dev/driver/unbind
        fi
        echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id
    fi
done

I've re-installed the patched linux-mainline package listed on the main page, but I'm still having the same issue of all my graphics devices being in the same IOMMU group. I'm running a Z87 chipset, would that cause any issues? Is there a specific patch I should apply for this chipset? Thanks a ton for the help.

Edit:

I've also read that this can potentially disable dri, which is something I need. Am I looking at a lost cause here?

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Try the V2 of the IOMMU patch: http://linux-kernel.2935.n7.nabble.com/ … 96884.html
Do not apply the old acs patch.
Edit: only works on Intel.

I run on qemu 2.0.0-RC1 and kernel 3.14, i have two graphique card AMD HD 6870 (crossfire not enable) on the VM (just for testing).

On dmesg i have :

Any help ?
Thanks

try

echo "options kvm ignore_msrs=1" >> /etc/modprobe.d/kvm.conf

Nop, i test it but nothing change, and i remove one card, so now i have only one GPU on my VM.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Just to get it right:
The IOMMU patch is meant to "rearrange" devices in the groups? At least this is what I understood from here
In my case the USB3 Controller and the sound card are in the same group as a pci bridge and several pci exporess root ports. Would be great if I could change that.

The error message says to make sure all of the devices in the group are bound to vfio.  The group, as you reported contains far more than just the secondary function of the device.  The IOMMU group on your system is large because the root port lacks PCIe ACS support.  If you wish to override that, look for the ACS override patch and options to use it (and caveats that enabling it implies).

Could of sworn I already applied the patch, I'll look into it when i'm back at my system. Thanks.

I've re-installed the patched linux-mainline package listed on the main page, but I'm still having the same issue of all my graphics devices being in the same IOMMU group. I'm running a Z87 chipset, would that cause any issues? Is there a specific patch I should apply for this chipset? Thanks a ton for the help.

Edit:

I've also read that this can potentially disable dri, which is something I need. Am I looking at a lost cause here?

You also need correct cmdline option in your bootloader otherwise the patch does nothing

I'm currently using:

intel_iommu=on pcie_acs_override=downstream pci-stub.ids=1002:6810,1002:aab0

Am I missing anything?

Also, does the linux-mainline package on the first page contain the second version of the patch?

Try the V2 of the IOMMU patch: http://linux-kernel.2935.n7.nabble.com/ … 96884.html
Do not apply the old acs patch.
Edit: only works on Intel.

I've tried to apply all three parts of the patch, however I'm getting "patch unexpectedly ends in middle of line" for 2/3 and 3/3. After doing this I realized that the patch may not work if there's an older version of the patch installed, or the same one is currently installed. Would I be correct or am I making some sort of silly mistake here?

Edit:

I've failed to mention that I'm fairly new with linux, sorry for any common questions that I may ask.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

I believe they are conflicting patch (that was the case for me), skip the "override_for_missing_acs_capabilities.patch" if you plan to use V2 patch, start fresh undo all patches and go from there.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Still not having much luck with vfio vga passthrough on my AMD R9 290 sad

I've tried pretty much all the suggestions I've seen on here but no matter what I try the guest always crashes after installing video drivers.

I did swap from Win8 to Win7 and noticed that after installing the video drivers and rebooting when windows boots up it crashes with a BSOD saying

"PAGE_FAULT_IN_NONPAGED_AREA"

I've tried the following:
multiple linux kernels all with the patches rolled in.
multiple Qemu versions (1.7.0, 1.7.1, 2.0.0RC0,1 &2) and have applied the vga reset patches
Tried both machine types of q35 and i440fx, of which both successfully passthrough the vga card but crash after installing the drivers and rebooting windows
Tried just passing through the Video card leaving out the HDMI Audio.
Tried installing drivers without installing the Catalyst Control Centre as suggested by some other forums.
Tried both AMD drivers and Windows Provided drivers via Windows Updates.
Tried using RomFiles

I'm guessing the problem lies within Qemu somewhere.

and still no change sad

Hi All,

I'm hoping someone will be able to help me out please. I've been trying to get vga passthrough working with qemu and vfio for a few months on and off but having no luck. I'm getting similar problems to users redger & DanaGoyette.

My hardware: CPU: i7 4770s, MB: Jetway NF9J-Q87 GFX: AMD R9 290

I used to use Xen 4.3 and had vga passthrough working just passing through the intel hd4600 controller to hosts, but since I got the AMD R9 290 card Xen doesn't seem to passthrough the card whatsoever, so thought I would try qemu and vfio.

I've tried using different linux versions and qemu versions but not having much luck. I am able to successfully vfio-bind my gfx card and I can start QEMU and get video via the GFX Card HDMI cable, I'm also able to successfully install Windows 8.1. However after installation I'm getting problems with either windows installing the amd drivers or using the catalyst driver installer, the host just reboots.

My latest setup:

linux 3.13.7-1 + i915 patch
Seabios git 1.7.4-66 (31Mar14)
Qemu 2.0.0 RC0 + patched pcibus_reset & assertion (https://lists.nongnu.org/archive/html/q … 05901.html & https://lists.gnu.org/archive/html/qemu … 00767.html)

Before the pcibus_reset patch I kept getting the following messages when the host rebooted while trying to install the drivers:

"qemu-system-x86_64 shows: hw/pci/pci.c:250: pcibus_reset: Assertion `bus->irq_count[\i] == 0' failed."

dmesg shows:  2805.839608 vfio-pci 0000:01:00.0: irq 46 for MSI/MSI-X


After applying the pcibust_reset patch the host no longer reboots after installing the drivers however the screen just goes blank so I have to manually kill the host. I do see the following messages:

qemu-system-x86_64 shows: ehci warning: guest updated active QH

dmesg shows:  4681.189513 vfio-pci 0000:01:00.0: irq 46 for MSI/MSI-X

This is my QEMU config:

/usr/local/qemu-2-0-0-rc0-patched-pci/bin/qemu-system-x86_64 -name win8 -enable-kvm -M q35 -m 6144  \

-drive file=/root/virtio-win-0.1-74.iso,media=cdrom,index=4,id=virtio  \
-device ide-cd,bus=ahci.2,drive=virtio

If I enable "-vga cirrus" and VNC to the host I can install the AMD drivers successfully and after a reboot it shows in device manager the AMD card but with a yellow exclamation and code 43. If I then go back to "-vga none" windows no longer wants to boot and I need up in a boot loop (seabios>windows booting>seabios>windows booting).

Any ideas please?

I've started fresh from the package on the main page, and have removed "override_for_missing_acs_capabilities.patch" from the pkgbuild and added in all three parts (in seperate files) of the ACS override patch. When I try to makepkg, I'm getting this:

I just know I'm missing something simple here, anyone see what it is? Do I need to edit the patches in some way?
