Hi,

I bind the gpu manually to vfio and qemu starts without errors but the attached screen stays black.
Edit: I blacklisted nouveau, nvidia, radeon and tried it without X but i had no success.
Are you using the patched seabios? have you tried swapping cards? perhaps using pcie_acs_override=downstream or mutlifucion (i have really no idea here)?
Some minutes ago i applied this patch (http://lists.gnu.org/archive/html/qemu- … 04300.html) to the nvidia source and build it (i am using PKGBUILD from nvidia-all). Now i can see the boot messages on the attached screen but i have no boot media to install and test windows .
What i have done to get it to this point:
clean arch install
kernel package from the first post with this patch (http://www.spinics.net/lists/kvm/msg92163.html)
qemu & seabios package from the first post
nvidia-all (https://aur.archlinux.org/packages/nvidia-all/) with this patch (http://lists.gnu.org/archive/html/qemu- … 04300.html)
manually attached devices to vfio (like in the usage examples http://lxr.free-electrons.com/source/Do … /vfio.txt)
$ cat /proc/cmdline 
BOOT_IMAGE=/vmlinuz-linux-mainline root=/dev/mapper/desktop-root ro pci-stub.ids=1002:68f9,1002:aa68 intel_iommu=on pcie_acs_override=id:8086:1e1e cryptdevice=/dev/sda2:main quiet
I think this works now, i'll check it later that day with a windows installation. Thanks for your ideas!

Thanks, this might help me too in my quest for three VMs with each having their own graphics cards. So what device are you giving the acs override command here

pcie_acs_override=id:8086:1e1e

. Is it a bridge or something else?

Yes, it's a pci root port/bridge. Before i used 'pcie_acs_override" every device behind that root port/bridge was in the same iommu_group.

I keep forgetting to post this:

If your Intel system won't boot with iommu=on enabled, it's a bug. Straight-up. I've gotten Xen working with passthrough PCI (though not at DomU boot) as far back as Ubuntu 12.04. However, under KVM at the moment, setting that option will result in your system not booting if you have a 0000:05:00.0 pci device. I tried other options, but that's basically what it came down to. Remove the extra PCI device. It will work. It's messed up, I know.

It's not a bug, to enable the iommu on intel the correct kernel parameter is intel_iommu=on, iommu=on might be a xen parameter but its completely unrelated to kvm, since xen is a type1 hypervisor with its own kernel.

I installed the ACS-patch also and now everything works! Also the 4x PCI slots now have the devices in their own iommu groups. Thanks for this info. So now I have 2 VM's both with their own graphics cards on top of the host . Arch + Windows 8 + Ubuntu 12.04.

Now I need another card to test 4 ... (and a PCIe extender cable, since I've run out of room a bit in the card department..)

Hey guys,

Note that I've tried pcie_acs_override = downstream, multifunciton, and singling out the vendor/device numbers for one of the root port. This output did not change.
iommu grouping on my motherboard is insane. If the videocard is on the first PCI express port, I only get the video card and the root PCI-E port. However, moving the card to the other port gives me this.

No its not, its here: http://www.spinics.net/lists/kvm/msg92163.html or here: http://marc.info/?l=linux-kernel&m=136993923507507&w=2 i did not include it since its not in alex tree and technically its unrelated

Thank you so much! Adding "pcie_acs_override=downstream" took care of the iommu_groups silliness. Now only the graphics card pieces show up.

The blue screen seems to happen across multiple driver versions (tried about 4 different drivers between the month my card launched and the latest beta). Same file: atikmpag.sys

Now, I don't know if this helps, but the situation is also bad with an Nvidia card: I swapped it out, reverted to a fresh, driver-less install (yay, ZFS), and installed it. No blue-screen, but also no working driver; driver fails to start and the system reverts to a pre-driver setup.

nbhs: I want to make 110% sure I'm not screwing it up on my end. Each piece of the puzzle I'm running the vfio-reset stuff (built from your packages; thanks again), but I just want to make sure I've installed each bit correctly; is there anything to look out for to verify this?

Have you tried with windows 8?

I tried Windows 7 64Bit and the vm runs fine. But when i install the latest ATI driver (ONLY the display driver) i get a bsod on reboot. Downloading Windows 8 now; 6 hours left...

guest : Ubuntu 13.04, kernel 3.8.0-27-generic (stock)

I've built the patched kernel, seabios and qemu - but I can't get an output on the screen connected to the GT620 when I use vfio. Qemu output is always blank / black as well. If I use "-device pci-assign" instead of "-device vfio-pci" then my guest os initializes the GT620 when starting X on the guest (no output at all before X starts). I can only get an output if I'm using the Nouveau-drivers on the guest, Nvidia binary drivers won't work. I've tried patching the drivers as well, but I've had no luck in getting the patched drivers to work. The output from dmesg on the guest :
[ 17.260770] NVRM: RmInitAdapter failed! (0x26:0x38:1170)
[ 17.260778] NVRM: rm_init_adapter(0) failed

the weird thing is that it seems like hdmi sound is initialized :

Also, when using -device vfio-pci I get an error message saying "qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on,romfile=/home/xbmc/GT620.rom: Warning, device 0000:01:00.0 does not support reset". This message does not appear when I use pci-assign, most likely because no kernel modules have been loaded for the GPU yet. I thought the patched kernel and/ or qemu would take care of resetting the device as well ?

So, today i took a chance to migrate to vfio-pci. But i got stuck at the point, where to start the DomU the first time. If i read the posts here right, the patched versions are for VGA-reset only (so for testing, i actually don´t need them?).

The last thing i did was to add the ivrs entry to the commandline. The AMD-Vi error has gone, but still the outcome is the same "Could not initialize SDL(No available video device) - exiting". There must be something I am missing (?)

Bash command:

qemu-system-x86_64 -enable-kvm -M q35 -m 1024 -cpu host -smp 3,sockets=1,cores=3,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=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on -device vfio-pci,host=01:00.1,bus=root.1,addr=00.1

So, today i took a chance to migrate to vfio-pci. But i got stuck at the point, where to start the DomU the first time. If i read the posts here right, the patched versions are for VGA-reset only (so for testing, i actually don´t need them?).

You need them

It also looks like your trying to passthrough your primary vga device, that wont work, the SDL error is because it doesnt have permission to access the X server, as a regular user try:

xhost +

guest : Ubuntu 13.04, kernel 3.8.0-27-generic (stock)

I've built the patched kernel, seabios and qemu - but I can't get an output on the screen connected to the GT620 when I use vfio. Qemu output is always blank / black as well. If I use "-device pci-assign" instead of "-device vfio-pci" then my guest os initializes the GT620 when starting X on the guest (no output at all before X starts). I can only get an output if I'm using the Nouveau-drivers on the guest, Nvidia binary drivers won't work. I've tried patching the drivers as well, but I've had no luck in getting the patched drivers to work. The output from dmesg on the guest :
[ 17.260770] NVRM: RmInitAdapter failed! (0x26:0x38:1170)
[ 17.260778] NVRM: rm_init_adapter(0) failed
the weird thing is that it seems like hdmi sound is initialized :

Also, when using -device vfio-pci I get an error message saying "qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on,romfile=/home/xbmc/GT620.rom: Warning, device 0000:01:00.0 does not support reset". This message does not appear when I use pci-assign, most likely because no kernel modules have been loaded for the GPU yet. I thought the patched kernel and/ or qemu would take care of resetting the device as well ?

From previous posts it looks like the intel driver also causes problems. Try blacklisting it and check if you get output with vfio

Sorry, i had the primary card cut out. It is a oldschool Matrox Millenium

05:05.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA 2064W [Millennium] (rev 01)

I had no X server In the last setup -> I installed it and the xorg-xhost too, but still noch change. I will now try your patched kernels.

*edit*

Found the following in this thread

Hm... beeing home a while and playing around with this, i installed the x server, some lxde for googling and so son ... qemu now starts without any SDL Error (inside a x session), but its just giving me a new blank window. At least qemu seems to be running now.
Sadly the output on the tv-screen (where the passed through card is connected via hdmi) is still just black. I don´t see the seabios messages. Removing "-vga none" shows the seabios then in the mentioned qemu window.
So i guess qemu is running into seabios, but i can´t see it on the passed-through card.

Is there any more debug-information i can grab?

*update* Got it! Looked like something in the patched qemu got corrupted. Redownloaded nbhs´ packages and everything went on smoothly

I'll start saying that I'm trying this with gentoo so I'm restricted to certain package versions; please don't scorn me.

I'm using a 3.10.5 kernel patched with:
- kernel-vfio-vga-reset.patch.tar.gz
- pci: Enable overrides for missing ACS capabilities

QEMU 1.5.2 patched with:
- qemu-vfio-vga-reset.patch.tar.gz

seabios 1.7.2.2 patched with:
- pciinit: Enable default VGA device

The cards:

My vfio-bind (I use this because all the cards used to be on the same IOMMU group, and even though now it's not the case anymore the result is the same):

#!/bin/bash

        vendor=$(cat /sys/bus/pci/devices/$dev/vendor)
        device=$(cat /sys/bus/pci/devices/$dev/device)

The cards get properly binded:

I tried swapping the cards and the displays, and nothing changes.
I want to think that I'm overlooking something simple. I just hope that is the case.

Well, one thing that bothers me is that some time after boot vgaarb does this:

[   22.719724] vgaarb: transferring owner from PCI:0000:01:00.0 to PCI:0000:03:00.0

But I don't know how relevant it can be. 02:00.0 doesn't work either after all.

EDIT:

I think I'm getting closer: I tried booting archlinux-2013.08.01-dual.iso instead of just testing the bios screen. The display was still black, but I tried grabbing the input and hitting enter and after a few seconds I saw the prompt and it worked.

Now, there are still a few problems:
- If I halt the guest system, qemu doesn't close itself, and even after I forcefully kill it the last image still stays in the monitor and doesn't go away until I re-run qemu. I'm guessing this means the card isn't getting reset?
- I also tried a Windows installation disc, but with that the display stayed black and when I tried to re-run the archlinux CD I got a kernel panic after a while (drm_kms_helper: panic occurred, switching back to text console). From then on the only way to get it to work again is to reboot the host.

Meanwhile dmesg... (2 "good" runs, 1 try with the Windows CD and the last one that ended with a kernel panic)

EDIT2:

Just tried to install an archlinux guest. Managed to complete the installation but when I rebooted the VM I couldn't get any kind of output from the display connected to the card. Switching to the cirrus card I could see that everything was fine and the card was there when I did lspci.
I also tried dumping the bioses of all my cards (got to mount them one at at time on the first PCIe slot since I couldn't manage to get the roms otherwise, damn Input/Output errors) and to run it with them. Nothing changed.

EDIT3:

Oh, I think I may have got it.
Changing the framebuffer device with "fbcon=map:1" lets the kernel use the right one.
So this means there is some other framebuffer device that gets priority during the boot process, namely:

fb0: EFI VGA frame buffer device

Is this part of the Q35? Time to investigate.

Hopefully we'll have this last issue snubbed out eventually. I'm good on non-vfio-pci, but vfio still blue-screens on that Radeon driver.

If this helps, I noticed also that the usb PCI device I pass through is also incredibly slow. As in, my mouse movement is very... choppy? Jerky? And the USB hotspot I hooked up worked but downloaded things VERY slowly (devices hooked up to the same spot via Wi-Fi did not have this issue). My hopes are that it's a software bug somewhere down the line, and possibly is related to having 000:05+ pci devices breaking iommu.

So I decided to try installing Windows 8, but since I couldn't manage to use the right card from the boot, I decided to try installing it with the cirrus and switching to the ATI afterwards, leaving the PCIe devices there (1), or just removing them and adding them after the installation is complete (2), or just hot plugging them once the system is fully installed (3).
Sure enough, all three failed:
BSOD with:

VIDEO_TDR_FAILURE (atikmpag.sys)

Now I'll try with pci-assign, which I wanted to avoid, but I'm losing hope.
It's quite disappointing since I built this system specifically with this in mind, and even though it's still quite immature it seemed the "cleanest" solution and I wanted to avoid the bloaded xen and vmware.

EDIT:

Almost forgot to say, the screen turned on before the BSOD, and stayed on even afterwards. On, and black.

EDIT2:

Well that worked. Well, almost: the jerky mouse makes the system unusable. The keyboard works fine and the animations seem fluid enough. Just the damn mouse. I had the same problem with the cirrus card, plus a constant "white refresh" in the the VM window (I don't know how to explain it... have you even seen what happens when you point an analog video camera to a CRT display? That.)
I even though that the problem was that I still had the VM window output enabled, so I tried "-vga none", but the screen stayed off, probably Windows refuses to boot because it can't find the primary graphic adapter or something like that; I also thought of "-nographic", but I don't know how can I grab mouse and keyboard after I start it like that.

Now I'm trying to make it work with an archlinux guest. It seems to work fine. That is, until I decide that I want X:

It looks like it can't identify the card, despite detecting it and loading the right drivers:

[    99.567] (--) PCI:*(0:1:0:0) 1002:68f9:174b:e233 rev 0, Mem @ 0xe0000000/268435456, 0xfea00000/131072, I/O @ 0x0000c000/256, BIOS @ 0x????????/131072

[    99.617] (II) RADEON: Driver for ATI Radeon chipsets:

Really, I don't get it.

EDIT:

Oh, that wasn't hard, I just needed to create a small xorg config file with this to use the right bus:

Section "Device"
    Identifier "Card0"
    Driver "radeon"
    BusID "PCI:1:0:0"
EndSection

The mouse is still unusable though. I think I'll connect some old mouse for the host and I'll passthrough the current one hotplugging it on occurrence on various guests.

I have try this on my new computer (Nvdia GTX 660 and Intel Hasswell 4600). I have patched seabios, qemu and kernel mentioned in the opening post. It works while using the ArchLinux cd but I can't get it work under Seabios and Windows. It looks like there is still something missing in Seabios to properly initialize the GPU. Using ArchLinux to visualize Linux isn't very useful for me so I hope someone knows how to fix this. I could of course provide some more debug information if someone can tell me what is useful.

While running qemu with -vga none it is by default not possible to grab the keyboard and mouse in the Qemu window. After searching for an option to enable this while not using a emulated video card driver I have found somekind of a hack. If you add '-device qxl' to the Qemu command you would get a second video card which is showed in the Qemu window. In my testing it looks it won't cause conflicts (probably because it doesn't have a video bios).
