VFIO Woes - GTX 1070 Reset Bug?

Been Having problems getting my VM with VFIO passthrough working. Can launch the VM, but can’t get a video output over HDMI. Destroying the VM is the only way to stop it, and GPU doesn’t get reset.

Motherboard: Asus CROSSHAIR VI Hero (x370)
BIOS Version: 7201
CPU: Ryzen 7 1700
GPU (Host): Nvidia RTX 2070
GPU (Guest): Nvidia GTX 1070

There is a polkit policy that allows users in the KVM group to manage libvirt.

/* Allow users in kvm group to manage the libvirt
daemon without authentication */
polkit.addRule(function(action, subject) {
    if (action.id == "org.libvirt.unix.manage" &&
        subject.isInGroup("kvm")) {
            return polkit.Result.YES;
    }
});

Running virt-manager as root, same issue. Also can’t shut down the VM, only destroy it. resulting in a reset bug.

Maybe an issue with the kernel? haven’t done this since the 4.xx kernels.

lspci -nnk

to check the 1070 does not have any nvidia or neuveaueueue drivers in use?

(as in to make sure the vfio-pic.ids= has grabbed the card’s gpu and audio bit)

there’s only two IDs for the 1070: 10de:1b81,10de:10f0

both grabbed by vfio-pci.

Cool, I just looked thru my notes, and it looks like you got all the steps right.

Can you drop the card for a bit, and run the VM with the spice console, see if windows event viewer has any errors logged?

I was attempting a fresh install, so i haven’t even gotten it to boot the installer yet.

i’m recreating my VM tonight, preinstalling windows & cloning the disk before i add the host cards.

Does load with the GPU attached, but still no video out of HDMI. maybe dead port? gonna try DVI in a sec.

:thinking:

Another Edit:

Swapped around some nvidia GPUs, still same result with an rtx 2070.

oh, and

 !!! Unknown header type 7f

when the device fails to reset.

got an update on it, im fairly certain i have the BIOS update issue with ryzen boards.

I’ll need to either find or build a kernel with the following patch.

have you tried giving it rom file? you can dump one using gpu-z and edit it using hex editor to remove nvidia flash header. I did so with my 2070

pretty sure it ain’t that, plus i don’t have a physical partition of windows to even run gpu-z on. Nuked that the other week since it kept causing problems with GRUB

more so since i know it previously worked before i did a BIOS update, and had previously worked with both the 2070 & 1070.

2 things that I found / helped me get my dual guest and boot GPU pass through are giving it proper ROM file and setting ROM bar on. If I remove ROM bar my guests fail to start. Though I think it’s on by default. Removing ROM bar caused what you are experiencing.

I’m just gonna chalk it up to having a cursed machine (or nvidia GPUs). tried to dump the vbios off the 1070 via the method from Proxmox, and tried some different kernel flags. still nothing.

If i remember, the last time i even had VFIO passthrough working on this box was with a RX580 as the guest GPU. Maybe it’s a sign i should just stick to passing through AMD gpus.

Actually I just checked the Asus website and there is a much newer BIOS update available v 7704. I was having troubles with resetting guests where my gpus would blank screen on restart. Updated bios solved that issue. There is also info I found on matheus website that says bios version after November 2019 fixes AGESA problems that causes problems with passthrough. Try flashing latest bios for your mobo. Unless there is a reason for using old BIOS.

Edit: Here is the link to the info. Scroll down to the BIOS settings part where he highlights the problems with bios versions.

picked up a discount 5700 XT off newegg, one of MSI’s dreaded EVOKE OC cards. absolutely no issues getting that one passed through to the VM.

btw, i run arch and arch-based distros.

@Kaiju I’m seeing so much inconsistent information on this topic. I wanted to check back - you had a reset bug issue with an NVIDIA card, and now you’re passing through 5700 XT and you haven’t experienced any reset bug - correct?
Thanks.

I eventually got it working tonight with the GTX 1070 (don’t think i can get it working with the 2070 yet) (gave up back in march after getting the 5700XT working.)

My particular motherboard was behind many bios revisions, and that included many AGESA updates and some fixes in regards to linux compatability.

Guess i had to dump and patch the 1070’s ROM as well. I presume i’ll need to do the same for the 2070, but im happy with just getting the 1070 working atm.

All that said, it ‘works’ but isn’t stable yet. just had a blue screen that flashed by quickly before restarting. Does seem to boot now without even using the patched ROM.

video_dxgkrnl_fatal_error (this may be due to corsair icue [absolutely icue, crashes when attempting to remove the driver]) Fixed.

Update on the 2070 setup: Works like a charm too.
