Qubes fails to boot using RX 5700 XT

[Jarrah Gosbell]

I have upgraded an existing Qubes system to use the AMD RX 5700 XT.
However, when booting with Xen, the driver is unable to install the GPUs
firmware. I receive the following error message:

```

amdgpu [...]: (-14) failed to allocate kernel bo
amdgpu [...]: failed to create kernel buffer for firmware.
amdgpu [...]: amdgpu_device_ip_init failed
amdgpu [...]: Fatal error during GPU init.

```

On the standard tty output, the screen will go blank at this point. On
the serial hypervisor console, I receive the above error message and
eventually am dropped at a non-interactive console login screen.


Solutions I have tried:

- Initially, the navi_* firmware files did not exist. I have added these
from a Fedora 30 install.

- All attempts have been on kernel-latest. Older kernels do not support
this card.

- Allocate exactly 6GB to dom0 to ensure no OOM or similar conditions
exist.

- Allocate exactly 4vcpus pinned to dom0.

- Tried multiple IOMMU settings and increased swiotlb.

- Booted Qubes without Xen. System boots perfectly to graphical login.

- All three options of amdgpu.fw_load_type with the following results

    0) Graphical system without Xen stops display. Can be interacted
with without the screen (eg ctl-alt-del results in a reboot). Xen
console session gives the below error:

```

[drm:amdgpu_device_init [amdgpu]] *ERROR* hw_init of IP block failed

```

    1/2) Graphical system boots fine. Xen console session shows the
first error described above.


I have been discussing this on Github here:

Thanks.

Saw you tried kernel-latest. Was that a 5.x version? If not, check if
it's available in Qubes repos (unstable?). Also, since you have built an
ISO try making a 4.1 one. It will have a newer version of Xen and dom0.

I have just tried this. No change. Using the serial console still
results in the same kernel panic. Without the serial console, there is
no output from Dom0.

I also was recommend pci=nocrs in the console output while testing. Same
result for this.


Of interest, while testing the above I accidentally left the Nvidia GPU
active. I received exactly the same kernel panic in serial console with
the Nvidia GPU as I usually do with the iGPU. It may be that the error I
am looking at is a result of the console, and the real error is
something else.

Thanks.

Please disregard the above. I replied to the wrong email.

It was. 5.3.7 is the version I have installed.

Currently building. I'll get back when it's done.

Having difficulty getting this to build. Qubes builder on a fedora 29
qube. `make qubes` runs fine. But `make iso` fails with the following
output:
