[Bug 1914986] Re: KVM internal error. Suberror: 1 - OVMF / Audio related

[Thomas Huth]

The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.

If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".

If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:

1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:

    https://gitlab.com/qemu-project/qemu/-/issues

and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.

2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).

Thank you and sorry for the inconvenience.

Status in QEMU:
  Incomplete

Bug description:
  This is latest release QEMU-5.2.0 on Arch Linux running kernel

  I'm seeing the following crash when loading an audio driver from the
  OpenCore[1] project in the UEFI shell:

  Here's the QEMU command line I'm using:

  qemu-system-x86_64 \
  -machine q35,accel=kvm \
  -cpu host,+topoext,+invtsc \
  -smp 4,sockets=1,cores=2 \
  -m 4096 \
  -drive 
file=/usr/share/edk2-ovmf/x64/OVMF_CODE.fd,if=pflash,format=raw,readonly=on \
  -drive file=OVMF_VARS.fd,if=pflash,format=raw \
  -usb -device usb-tablet -device usb-kbd \
  -drive file=OpenCore-0.6.6.img,format=raw \
  -device ich9-intel-hda,bus=pcie.0,addr=0x1b \
  -device hda-micro,audiodev=hda \
  -audiodev pa,id=hda,server=/run/user/1000/pulse/native

  The driver loads fine when using the "no connect" switch. eg:

  Shell> load -nc fs0:\efi\oc\drivers\audiodxe.efi
  Shell> Image 'fs0:\EFI\OC\Drivers\AudioDxe.efi' loaded at 7E3C7000 - Success

  However, the crash occurs when loading normally.

  Any ideas? Thanks.
